[Stape webinar] Conversion signals & server-side tracking: how digital agencies can maximize ad performance

Published
Feb 11, 2026

Ad platforms are phasing out manual optimization tools, leaving advertisers with one key lever: the signals they send back. As automation takes over, the quality of those signals increasingly determines how well campaigns perform.

In this webinar, we’ll take a practical look at conversion signals - what they are and why they matter. We’ll also show how the Stape platform supports the implementation of both online and offline conversion signals. Advertisers still sending weak data to ad platforms will continue to fall behind those who’ve learned how to show platforms what “good” looks like. With signal quality emerging as a key trend for 2026, now is a great time to get clear on the fundamentals.

Common questions and answers

We covered this topic in depth in our previous webinar (recording): https://www.youtube.com/watch?v=6DPs8w86CA0

We wouldn’t choose one over the other. First, make sure your signal volume is as close to 100% as possible compared to your source of truth (CRM/CMS). Then, enrich events with as many relevant parameters as you can send to the platform. In practice, ad platforms value user data the most (in addition to basics like IP address and user agent). Better user data helps platforms build stronger audiences and optimize toward people who are more likely to convert.

Yes, this is a good use case for offline conversion tracking. See: https://stape.io/blog/ways-of-offline-conversion-tracking#what-is-offline-conversion-tracking

Google Ads Offline Conversions includes an “unknown” consent option for cases like this. If you’re in a GDPR jurisdiction and you have not received valid consent, you may not be able to legally transfer those conversions (and there can be local nuances). We recommend checking with your solicitor or DPO for the correct approach in your jurisdiction.

Both matter, but signal quality directly impacts how effectively your ad spend can work—so improving signals often makes your media budget perform better.

If you have no control over the third-party domain where the conversion happens, server-side tracking typically won’t work there, because you need a validated custom domain to operate in a first-party context. That said, many third-party platforms allow you to host part of their service on your subdomain, which solves the issue. Another common option is a redirect to a custom thank-you page on your domain, where you can track the conversion as usual.

In practice, you usually validate this through improvements in performance metrics—more attributed conversions and better ROAS (and/or lower CPA), assuming everything else is held reasonably consistent.

EMQ is heavily influenced by the user data you provide. In general, the more click identifiers (and other relevant parameters) you send, the higher the score can be. So it’s not that low spend “hurts” EMQ—rather, higher spend can sometimes increase the amount of identifiable traffic, which may improve EMQ.

The main option is cross-device/cross-browser tracking. However, it’s complex and can introduce drawbacks—especially the risk of incorrect/false attribution.

COGS is a native parameter, so you’re effectively delegating the calculations to Google. If you send profit directly, you have more flexibility in how you build reporting and performance dashboards.

Use a landing page on a subdomain of the main site. That way, you’re less likely to lose cookies and other attribution attributes.

Store the user’s consent status in your CMS/CRM. Then include that consent status in the webhook payload sent to your server-side GTM endpoint. Based on that field, you either send conversions or suppress them. In some cases, you can also enforce consent at the webhook-sending stage (depending on the CMS/CRM).

It depends on your experience and the scope (number of platforms, events, and complexity). It can range from a few minutes (simple ecommerce + one platform) to several days (complex flows with many platforms and events).

Sometimes there’s another data layer implementation (or a “rogue” setup) firing the same event somewhere in the code. Adding _stape helps ensure you don’t double-count events if another add_to_cart is firing.

Yes—if you have complete user data and a high percentage of fbc. In practice, we rarely see scores above ~9.3.
