Conversion Tracking Verification Process: Unmasking the Lie in the Dashboard

The verification step is where the whole category breaks down. Every article about conversion API tools in 2026 tells you how to set one up. Which tags to fire. How to check your Event Match Quality score. How to confirm deduplication is running. None of them ask the question that actually determines whether any of it matters: what is in the signal you just verified?

You can have a perfectly implemented CAPI stack. EMQ of 9.1. Zero API errors. Clean deduplication. And still be sending Meta a steady stream of bot conversions, crawler events, and VPN traffic, all neatly matched, beautifully hashed, firing on schedule. The pipeline works. The water is poisoned. Your Events Manager shows green lights on data that is teaching Meta's algorithm to find more of whatever sent those events.

That is the verification failure nobody names. The tools validate the pipe. Nobody validates the source.

Project Andromeda, fully deployed October 2025, acts on contaminated conversion signals within hours, not weeks. The old window where bad data sat inert long enough for you to catch and correct it is gone. Bad events reach the Lookalike engine the same day they fire. By the time you notice your CPA climbing, the audience has already been retrained.

This is not a setup problem. It is a data quality problem that sits upstream of every tool in this category.

What every verification guide gets wrong

The standard CAPI verification checklist is: check Events Manager for server events appearing, confirm event_id deduplication is working, target EMQ above 6.0, use the Test Events tool. This is all correct. It is also entirely about pipe integrity, not data integrity.

Pipe integrity asks: is the signal reaching the platform? Data integrity asks: should that signal have been sent at all?

A bot hitting your purchase page generates a real server event. It passes deduplication checks because it has a unique event_id. It raises your EMQ when it carries a hashed email from a fraud domain. It shows in Events Manager as a healthy conversion. Every green light is on. None of this tells you the conversion was a human.

According to Fraudlogix's 2026 report, global invalid traffic runs at 20.64%. On Meta's Audience Network that figure reaches 67%. Even on core Meta placements the average IVT rate is 8.20%, with Instagram running at 38%. If you are spending on Instagram and running a standard CAPI setup with no pre-filter, you can conservatively assume more than one in three events you send does not represent a real person.

The verification question is not "did it send?" It is "what did it send?"

The five things a real verification process actually checks

1. Traffic source hygiene before the event fires

By the time you are checking EMQ scores, the event has already been sent. Verification that matters runs before any event reaches your CAPI endpoint. That means checking whether the IP generating the event belongs to a datacenter, a known VPN exit node, a residential proxy, or an AI agent framework before you decide to forward it.

There are roughly 361 billion IP addresses worth tracking across those categories. The split matters: datacenter IPs running headless browsers look like residential traffic to a pixel but behave like bots at the server layer. Proxy traffic cycles residential IPs specifically to defeat IP-based filtering. Identifying these before the event fires is not a CAPI feature. It is a pre-filter that has to sit upstream of any CAPI implementation.

Most tools in this category do not have one.

2. Consent-gated event suppression by geography

GDPR applies to EU traffic. It does not apply to a visitor in Ohio. Running cookieless or consent-gated tracking globally because it is simpler than geography-aware logic means you are treating every returning US customer as a stranger, no funnel, no attribution, just a fresh anonymous session. Your CAPI is receiving degraded signals for traffic that never needed to be degraded.

The correct verification check here is: does your consent layer activate conditionally by region? For EU users, does it actually load on every session, including sessions from browsers running uBlock Origin or Brave? Third-party CMP scripts from OneTrust and Cookiebot load from third-party CDNs that ad-blocker filter lists target by name. On privacy-conscious browsers, the banner never loads, consent is never collected, and your identity resolution never activates for users who would have consented if the banner had appeared.

A first-party CMP that loads from your own subdomain does not appear on any filter list. The banner loads on every session. Consent is actually collected. The verification check is simple: is your CMP on a third-party CDN or your own?

3. The reject-all bucket

Most CMP implementations put "reject all" data and identifiable data into the same collection pipeline, then drop everything when consent is not given. This is wrong legally and operationally. Anonymous analytics remain lawful after consent rejection in the EU. There is no legal basis for discarding them, and there is no operational reason to. You are allowed to know a user visited, how long they stayed, and what they clicked. You are not allowed to identify them.

Throwing all of that into a single bucket and discarding the bucket means you are losing 60 to 70% of the intelligence you were permitted to keep. The verification check: does your consent layer distinguish identifiable data from anonymous data, or does it treat rejection as a complete data blackout?

4. Deduplication versus double-counting

The standard advice is correct here: browser events and server events need matching event_id values so the platform can merge them and not count one conversion twice. If your deduplication rate shows events being doubled, ROAS reports at 2x reality and every optimization decision downstream is made on inflated numbers. The verification is straightforward in Events Manager and worth doing weekly, not just at setup.

What the standard advice misses: deduplication tells you about structure, not volume. A perfectly deduplicated set of bot conversions is still a set of bot conversions. Green deduplication status does not mean clean data.

5. The downstream audit: do your platform numbers map to anything real?

Pull your CAPI-reported conversions for any 30-day window. Now pull the same period from your CRM, your Shopify backend, your payment processor. If your Meta CAPI shows 1,400 purchase events and your payment processor shows 900 completed orders, the delta is worth explaining. Some of it is legitimate attribution differences. Some of it is bots completing form fills or checkout steps that never resulted in actual payment.

PillarlabAI ran this audit on four weeks of signups: 4,560 total events reached their CAPI pipeline, 730 were real humans. 84% fraudulent. 650 accounts traced back to a single laptop. Their EMQ was fine. Their deduplication was fine. Their CAPI implementation was technically correct. The data was garbage.

The buyer's decision tree

The right tool depends on what problem you are actually solving. Most buyers in this category conflate three separate problems: signal delivery (are events reaching platforms reliably), signal quality (are those events from real humans), and attribution accuracy (are the events matched to the right campaigns and users). Different tools solve different problems. Almost none solve all three.

You need signal delivery and nothing else

You are on Shopify, running Meta and Google ads, volume under $500K/month GMV, no EU traffic to speak of. Your pixel is leaking events to ad blockers and iOS privacy restrictions. You need server-side relay. This is the majority use case in 2026 and several tools solve it well at reasonable prices.

You need signal quality plus delivery

You have seen CPAs increase without obvious cause. Your targeting has drifted. Your Lookalike audiences are converting at lower rates than they used to. You have reason to suspect your CAPI is feeding contaminated data into the algorithm. You need a tool with pre-event bot filtering, not just reliable event forwarding.

You need multi-platform plus quality plus consent

You advertise on Meta, Google, TikTok, and LinkedIn. You have EU traffic. You need a CMP that actually loads, consent-gated identity resolution, and bot filtering before any platform receives an event. This is the most demanding requirement set and the one most tools in this category only partially address.

You are an agency managing multiple client accounts

You need infrastructure you can deploy and maintain across clients without bespoke developer work per account. The setup complexity and per-account cost structure matter more than raw feature set.

Tool coverage

DataCops

DataCops is the only tool in this category built around the verification problem first. The architecture is: filter the traffic before any event fires, then route what remains through first-party CAPI to Meta, Google, TikTok, and LinkedIn. The bot filtering runs against a live database of 361 billion tracked IPs spanning datacenter, residential, VPN, and proxy categories, plus 160,000 fraud email domains. Bots, crawlers, Puppeteer and Selenium instances, and AI agent traffic are filtered before any event reaches the CAPI pipeline.

The first-party CMP loads from your own subdomain rather than a third-party CDN, which means it is not on any ad-blocker filter list and loads on every session including Brave and uBlock Origin. EU users see the banner. Consent is recorded. Anonymous analytics flow unconditionally after rejection because anonymous data is always legal. Identity resolution activates on consent. Non-EU users get cookieless persistent identity without requiring a banner at all. No cookie expiry, no ITP degradation, no seven-day drop-off on returning user recognition.

The conversion API supports Meta, Google Enhanced Conversions, TikTok Events API, and LinkedIn Insight CAPI from one pipeline. Setup is one script tag plus one CNAME record, live in 5 to 30 minutes on Shopify, WooCommerce, Webflow, or custom builds.

Where it falls short: SOC 2 Type II certification is still in progress, which disqualifies it for enterprise procurement at some organizations. The integration catalog is narrower than Segment or Tealium. It is a newer brand than Elevar or Stape in a category where longevity carries weight with certain buyers. CAPI starts at the Business plan at $49/month. The Free and Growth plans at $0 and $7.99/month include analytics and CMP but no CAPI forwarding.

Right for: any advertiser where bot contamination is suspected, multi-platform setups that need Meta plus Google plus TikTok plus LinkedIn from one stack, and EU advertisers who need a CMP that actually loads. Value 9/10. Pricing: Free, $7.99/month, $49/month (CAPI), $299/month, Enterprise custom.

Stape

Stape is the leading managed Google Tag Manager server-side container hosting platform. It is not a conversion tracking tool in the traditional sense. You bring your own GTM setup, Stape hosts the server container on infrastructure it manages so you do not need to spin up your own Google Cloud or Cloudflare Worker instance. The pre-built template library covers Meta CAPI, Google Enhanced Conversions, TikTok Events API, and dozens of others. The Custom Loader feature routes your GTM client-side requests through a first-party subdomain, which bypasses most ad blockers.

What you get is infrastructure flexibility with full GTM control. What you do not get is anything out of the box. No bot filtering. No consent management. No analytics layer. Everything has to be assembled and maintained inside the GTM container. Google Tag Gateway launched in January 2026 as a free Google-only server-side option, which undercuts part of Stape's value for single-platform Google setups. But for teams managing complex multi-platform implementations across many clients, Stape remains the most flexible infrastructure layer at a reasonable price.

Where it breaks: requires real GTM expertise to configure and maintain. Support is not unlimited. The $17/month Pro plan covers hosting but Cloud Run infrastructure adds $50 to $300/month depending on traffic. An agency that does not already live in GTM will find the total cost of ownership significantly higher than the headline price suggests.

Right for: in-house GTM engineers and agencies with existing server-side GTM expertise who want flexible hosting without managing cloud infrastructure. Value 7/10. Pricing: $17/month Pro, $83/month Business, plus Cloud Run $50 to $300/month.

Elevar

Elevar is the gold standard for Shopify-native server-side tracking. It has been doing this longer than most competitors, and the depth of Shopify integration shows. It handles checkout steps, post-purchase events, subscription renewals, Express Checkout ClickID relinking, and cross-device identity resolution in ways that a generic server-side relay does not. Brands like SKIMS, Vuori, and ColourPop use it. The conversion accuracy monitoring dashboard flags data quality issues before they compound.

The honest limitation is pricing. For stores doing meaningful Shopify volume, Elevar escalates fast. The entry plan is around $200/month for 1,000 orders, and the Business tier at $950/month for 50,000 orders is a significant line item for a mid-market DTC brand. There is no bot filtering. High-fidelity bot events reach Meta with better match quality than a standard pixel would produce, which is arguably worse than doing nothing because the signal is both wrong and confident. The platform is also Shopify-only, which limits its utility for brands selling across multiple platforms or running B2B alongside DTC.

Right for: Shopify-only stores above $500K/month GMV where order-level fidelity and deep checkout attribution justify the premium. Value 7/10. Pricing: approximately $200/month entry, $950/month Business, per-order overages apply.

Tracklution

Tracklution is a fully managed server-side tracking service positioned as a simpler, no-GTM alternative to Stape. It supports Meta CAPI, Google Enhanced Conversions, TikTok Events API, and GA4, with setup times comparable to DataCops rather than the hours a GTM container requires. SOC 2 Type II and ISO 27001 certifications make it viable for enterprise procurement conversations where DataCops currently is not.

The EU-leaning design is both a feature and a limitation. Tracklution handles consent mode and GDPR compliance thoughtfully, which is why it wins with EU-based agencies. The weakness is no bot filter. Events go to platforms as received, without pre-filtering. For high-traffic accounts in bot-heavy verticals, the CAPI overage costs on fake events are real money.

Right for: small to mid EU agencies wanting clean server-side delivery without GTM expertise, particularly where compliance certifications are a procurement requirement. Value 7/10. Pricing: €31/month Starter, custom Enterprise.

TrackBee

TrackBee is a purpose-built Shopify tracking tool that handles Meta CAPI, Google Enhanced Conversions, TikTok Events API, and Klaviyo integration with no GTM dependency. The five-minute setup claim is credible, and the cross-device identity resolution built into the Shopper Profile system is more developed than most no-code competitors. The Klaviyo integration is particularly strong for DTC brands running email alongside paid, where tying email engagement to ad attribution requires careful cross-channel identity work.

The weakness is scope. TrackBee is Shopify and the ad platforms it supports. It is not a consent solution, not an analytics layer, not a bot filter. If you need multi-platform beyond Shopify or B2B tracking alongside DTC, you are in a different category.

Right for: Shopify DTC brands without technical resources that run Meta, Google, TikTok, and email in parallel and want setup without GTM. Value 7/10. Pricing: €79/month.

Littledata

Littledata earned its reputation on one specific problem: making GA4 actually work on Shopify. Standard GA4 implementations routinely miss checkout steps, misattribute revenue, and handle subscription renewals incorrectly. Littledata fixes this by routing Shopify order and session data server-side to GA4 directly, bypassing GTM entirely. Subscription revenue tracking through Recharge is among the strongest implementations in this category. Future Kind increased checkout event capture by 205% after switching.

The ad platform CAPI coverage is functional but secondary to the GA4 focus. If your primary pain is inaccurate GA4 reporting, Littledata is the surgical fix. If your primary pain is Meta CAPI signal quality, you will want something else. No bot filtering. Pricing scales with orders which creates cost visibility challenges as stores grow.

Right for: Shopify subscription businesses with strong GA4 reliance where accuracy in analytics is more important than expanding ad platform coverage. Value 7/10. Pricing: $199/month Standard, scales by order volume.

Triple Whale

Triple Whale sits in a different category from pure CAPI tools. It is an attribution and analytics dashboard with server-side tracking underneath. The Pixel, Sonar for server-side, and the attribution dashboard together make it useful for DTC brands that want a single view of creative performance, customer LTV, and blended ROAS without assembling multiple tools. The product intelligence layer and spend tracking are genuinely differentiated.

The limitation for verification purposes: Triple Whale improves how you read data. It does not filter what goes in. The same bot conversions that pollute a basic CAPI stack also flow into Triple Whale's attribution engine. The dashboard will be beautifully designed and just as wrong. It also covers Shopify-native DTC primarily. B2B SaaS, WooCommerce, and multi-platform scenarios are under-served.

Right for: Shopify DTC brands wanting one dashboard for creative performance, attribution, and spend optimization who understand the analytics layer is downstream of tracking quality. Value 6/10. Pricing: $179/month annual, $259/month Advanced, GMV-based pricing above $5M.

Northbeam

Northbeam is enterprise-tier marketing attribution using machine learning to model channel contribution across your media mix. It is expensive and designed for accounts with the data volume and ad spend to make MMM meaningful. The $1,500/month entry price means a sub-$2M revenue business is unlikely to generate the signal volume that makes Northbeam's modeling useful.

No bot filtering. The ML models are only as good as the events they ingest. At Northbeam pricing, contaminated training data is an expensive problem.

Right for: enterprise brands with $10M+ annual ad spend that want media mix modeling and are staffed to act on it. Value 6/10. Pricing: $1,500/month entry, scales $5,000 to $10,000+.

SignalBridge

SignalBridge is notable in this list for including bot filtering alongside standard CAPI delivery. It is one of very few tools at SMB pricing that treats signal quality as a first-class feature rather than an enterprise add-on. Analytics, bot filtering, and funnel insights are included at $29/month, which makes it worth serious consideration for any buyer where budget is the primary constraint but data hygiene still matters.

The IP database depth and proxy detection capabilities are not disclosed in the same detail as DataCops' 361 billion IP database, which makes like-for-like comparison difficult. Multi-platform support covers the core platforms. For buyers who want bot filtering but cannot justify $49/month, SignalBridge is the nearest alternative.

Right for: budget-constrained SMBs that need basic bot filtering alongside server-side delivery and cannot justify higher-tier pricing. Value 8/10. Pricing: $29/month.

Cometly

Cometly is an AI-driven attribution platform built for B2B SaaS and longer sales cycles where the gap between ad click and closed-won revenue spans weeks or months. The server-side tracking feeds into a multi-touch attribution model that ties ad spend to CRM outcomes. For B2B teams running LinkedIn alongside Meta and Google, where standard CAPI reporting attributes nothing to pipeline, Cometly provides attribution visibility that pixel-only setups never will.

The pricing is sales-led and ranges widely. The tool is not designed for ecommerce and should not be evaluated on ecommerce criteria. It solves a B2B attribution problem that most tools in this category simply ignore.

Right for: B2B SaaS and high-consideration product teams where the purchase cycle extends beyond a single ad click and CRM attribution is the primary measurement goal. Value 7/10. Pricing: $199 to $499/month, sales-led.

CustomerLabs

CustomerLabs is a no-code first-party customer data platform that lets marketers configure server-side CAPI connections through a visual interface without GTM or developer involvement. The real-time audience syncing capability is differentiated: it pulls behavior and CRM data and activates it across Meta, Google, and LinkedIn as dynamic custom audiences, not just conversion events.

The $99/month entry price is accessible, though the pricing model scales by tracked users which creates cost unpredictability at volume. No bot filtering. The platform is strongest for marketing teams that have collected first-party data they want to activate across ad platforms rather than teams primarily trying to recover pixel signal loss.

Right for: marketing teams with existing first-party data they want to activate across ad platforms without developer support, particularly for B2B where CRM-to-CAPI activation matters more than ecommerce funnel tracking. Value 7/10. Pricing: $99/month entry, usage-based scaling.

Analyzify

Analyzify takes a done-for-you configuration model: you pay a setup fee and they configure GA4 and Google Ads tracking for your Shopify store correctly. There is ongoing support available. For early-stage Shopify merchants under 500 orders/month that do not have the internal resources to configure GTM and want expert setup without a recurring high monthly cost, the model makes sense.

The limitation is flexibility. If your store setup changes significantly, reconfiguration is an additional paid engagement. There is no self-serve adjustment. And the coverage is GA4 and Google Ads, so brands running Meta and TikTok need to add something else.

Right for: early-stage Shopify stores that want correct GA4 and Google Ads tracking configured properly once, without ongoing technical overhead. Value 6/10. Pricing: one-time setup fee model, ongoing support tiered separately.

WeltPixel Conversion Tracking

WeltPixel covers GA4, Meta CAPI, TikTok, and Google Ads in one flat-price Shopify app. The predictable pricing is the main selling point: unlike Elevar or Littledata, WeltPixel does not escalate with order volume. For stores anticipating growth where per-order pricing creates uncertainty, the flat rate model offers real planning value.

The depth is shallower than dedicated solutions. Elevar's Shopify-native checkout attribution is more developed. Littledata's GA4 subscription handling is stronger. But for stores that need core coverage across multiple platforms without GTM complexity and want a bill that does not surprise them, WeltPixel is worth evaluating.

Right for: growing Shopify stores running Meta, Google, and TikTok that want flat-rate predictable pricing without GTM expertise. Value 7/10. Pricing: flat-rate, check current Shopify App Store listing.

Trackify

Trackify focuses on Meta Pixel and TikTok Pixel tracking for Shopify. It handles the core use case cleanly and is straightforward to set up. For stores that advertise primarily on Facebook and TikTok and have no immediate need for GA4, Google Ads Enhanced Conversions, or LinkedIn, Trackify avoids unnecessary complexity.

It is a narrow tool, and that is its value proposition. The moment you need Google Ads attribution or GA4 accuracy, you are adding another app alongside it.

Right for: Shopify stores running primarily Meta and TikTok ads that want simple reliable pixel and events tracking without broader platform coverage. Value 6/10. Pricing: tiered by events/month, starts under $30/month.

Meta Conversions API Gateway (1-click, free)

Meta launched free one-click CAPI on April 15, 2026. For Meta-only advertisers with a single Shopify or WooCommerce store, no EU traffic, and no need for Google or TikTok conversion data, this is the correct answer. It is free, deduplication works, and Meta obviously prioritizes signals from their own infrastructure.

What you do not get: no bot filtering, no multi-platform, no consent management, no analytics layer, no Google CAPI, no TikTok, no LinkedIn. It is also worth noting that high-quality bot signals flowing through Meta's own CAPI reach the algorithm faster and with less friction than through any third-party tool. Free does not mean clean.

Right for: single-store Meta-only advertisers with simple setups and no EU compliance requirements. Value 9/10 for what it is. Pricing: free.

Google Tag Gateway

Google launched Tag Gateway in January 2026. Free server-side Google tracking hosted on GCP, Cloudflare, or Akamai with one-click setup. For Google Ads Enhanced Conversions and GA4 server-side event delivery, this is the lowest-friction option available. Combined with Meta's free 1-click CAPI, a budget-constrained advertiser can have server-side delivery on both major platforms for zero monthly tool cost.

The same caveat applies: no filtering, no consent management, no LinkedIn or TikTok. Infrastructure, not intelligence.

Right for: Google-focused advertisers or anyone adding Google server-side tracking to an existing Meta setup at zero cost. Value 9/10 for what it is. Pricing: free.

Datahash

Datahash is an enterprise-grade first-party data and CAPI solution designed for large advertisers with custom data pipelines and compliance requirements. It handles data clean rooms, identity resolution, and multi-platform activation at a level that SMB tools do not attempt. The pricing reflects the segment: most deployments run $500 to $2,000/month on custom contracts.

Right for: large enterprise advertisers with dedicated data engineering teams running complex multi-channel attribution at scale. Value 7/10. Pricing: custom, typically $500 to $2,000/month.

Aimerce

Aimerce is a dedicated Meta CAPI and Google Enhanced Conversions relay for Shopify with strong EMQ optimization focus. The Durable ID system for cross-session user re-identification is more developed than standard pixel approaches, and the Express Checkout ClickID relinking handles a common attribution gap on Shopify checkouts. It positions explicitly on EMQ scores and conversion recovery rates.

The weakness is the same Layer 5 problem: no bot filter. Aimerce delivers bot-contaminated events to Meta at higher match quality than a standard pixel would. The signal is technically cleaner but not data-quality clean. For EU traffic, the consent handling has been flagged as a GDPR Article 6 exposure in some implementations. The $299/month base price with usage-based escalation above 1,000 orders makes total cost unpredictable for growing stores.

Right for: Shopify advertisers with high Meta spend where maximizing EMQ on real human traffic is the primary goal and bot contamination is not a concern in their vertical. Value 6/10. Pricing: $299/month base, usage-based above 1,000 orders.

Hyros

Hyros is a premium attribution platform designed for info-product businesses, coaches, course creators, and high-ticket offers where multi-step funnels span webinars, email sequences, and multiple ad interactions before a purchase. The AI attribution logic and lifetime value tracking across long sales cycles is genuinely differentiated for that use case.

It is expensive, sales-led, and not designed for ecommerce or B2B SaaS. The value is specific to the funnel type it was built for.

Right for: info-product businesses and high-ticket offer owners where multi-touch attribution across a complex pre-purchase journey is more important than ecommerce conversion tracking. Value 7/10 for its intended use case. Pricing: $1,000 to $5,000/month, sales-led.

Feature comparison

When not to use DataCops

There are four scenarios where a competitor is the more sensible choice.

You are a Shopify-only store above $500K/month GMV with a dedicated analytics team and the primary pain is checkout attribution fidelity at the order level. Elevar's Shopify-native depth, its understanding of checkout steps and post-purchase events, and its established integrations with Shopify's data layer are worth the premium. DataCops is a better fit for multi-platform needs and bot filtering. Elevar is a better fit for Shopify-deep attribution accuracy.

You are an agency or in-house team with strong GTM expertise that wants maximum flexibility over your tracking container. Stape gives you full server-side GTM control at lower infrastructure cost than managing your own Cloud Run setup. DataCops is an outcome, not infrastructure. If you want to build and own the implementation, Stape is the right foundation.

You are in enterprise procurement and need SOC 2 Type II certification today. DataCops is in progress. Tracklution (SOC 2 Type II, ISO 27001) or Datahash meet that procurement requirement now. This is a real constraint for regulated industries and enterprise buyers.

You advertise only on Meta and have no EU traffic and no bot concerns in your vertical. Meta's free 1-click CAPI launched April 15, 2026. There is no argument for paying $49/month for a tool when a free native solution covers your use case exactly.

How to run the actual verification

Pull your last 30 days of CAPI-reported conversion events. Match them against your payment processor or CRM records for the same period. The delta between events sent and verified transactions is your contamination floor. Some gap is legitimate attribution difference. A gap above 20% is a signal quality problem.

Pull your top 50 source IPs from your server logs for the same period. Run them against a datacenter, VPN, and proxy database. If more than one in five belongs to a non-residential category, your events include non-human sources.

Check whether your CMP is loading on sessions from browsers with uBlock Origin or Brave enabled. Use a VM with uBlock active, visit your site, check the network tab for your CMP script loading. If the banner does not appear, your consent layer is not working on the traffic most likely to be privacy-conscious, and your identity resolution is not activating on users who would have consented.

Check your geographic consent logic. If your cookieless tracking fires the same way in Germany as it does in Texas, you are either over-collecting in the EU or under-collecting in the US.

These four checks take an hour. They will tell you more about your data quality than EMQ scores and deduplication reports combined.

The question worth sitting with: if you ran that verification process on last month's CAPI data, what percentage of the conversions you sent Meta can you prove came from a human being who made a real decision?
