Server-Side Tracking & CAPI: Recover Every Conversion

Your client-side pixels are losing 20–40% of conversions to Safari ITP and ad blockers. Server-side tracking and CAPI get them back.

I implement a server-side data collection architecture (GTM server container / sGTM) along with each ad platform's Conversions API — Google Ads (server-side), Meta CAPI, Microsoft/Bing, TikTok, Pinterest — to rebuild reliable measurement, extend first-party cookie lifespans, and send platforms complete, deduplicated conversion signals.

How Blockers Are Hurting Your Business

Broken Attribution

On Safari, cookies expire after 24 hours or 7 days. A purchase made 8 days later shows up as 'Direct' instead of 'Paid.'

Shrinking Audiences

Your remarketing lists keep getting smaller because ad blocker extensions block pixels before they fire.

Missing Conversions

Around 20–40% of your users run ad blockers. That's a significant share of conversions that never appear in your reports.

Frequently Asked Questions

What is the Conversions API (CAPI) and how is it different from a pixel? +

A pixel runs in the browser and can be blocked by ad blockers or ITP. The Conversions API sends the conversion event from your server directly to the ad platform (Meta CAPI, Google Ads server-side, Bing). We use both together with deduplication for complete, resilient measurement.

Server-side for Google Ads, Meta, and Bing — what are the differences? +

Each platform has its own server channel: Google Ads (server-side via sGTM / Google Ads API), Meta via the Conversions API, and Microsoft/Bing via Offline/Server-to-Server. I implement the right connector for each platform while maintaining a single source of truth in the GTM server container.

Do I really need a GTM server container (sGTM)? +

It's the most robust option: a server-side GTM container hosted on a first-party subdomain that orchestrates event forwarding to all ad platforms. This is what I deploy and maintain for you.

Does server-side tracking stay resilient to GDPR? +

No. Technically it could be used to track without consent, but that's not allowed. I configure the server-side setup to strictly honor user consent choices from your consent banner (Consent Mode v2).

Will I see more measured conversions? +

Yes — typically a 10–20% increase in measured conversions as soon as the setup goes live, thanks to better signal capture. There's no artificial inflation: we're simply recovering conversions that were already happening but going untracked.
