Your Meta ads rely on data — but what if that data is incomplete?

Browser privacy restrictions, ad blockers, and short cookie lifetimes are cutting off valuable insights, causing missed conversions and wasted ad spend.

Without accurate data, Meta’s AI struggles to optimize targeting, leading to higher costs, poor attribution, and underperforming campaigns.

Watch our webinar to learn how to recover lost data, improve attribution, and boost ROAS with a scalable data tracking setup.

Speakers:

  • Rohith Bhatia, Global Partnerships Marketing Manager @ Meta
  • Dan Murov, Data Tracking Lead @ Stape

✨ What you’ll learn:

  • Why your Meta Ads underperform – how tracking gaps lead to lost conversions and wasted ad spend
  • How to fix tracking gaps & improve attribution – what Meta Conversions API is, how it works, and which implementation option to choose
  • Real-world success story – how businesses improved ROAS and client retention by switching to server-side tracking
  • Common tracking challenges – how to streamline setup, avoid troubleshooting, and scale CAPI setup across multiple clients
  • How Stape simplifies Meta CAPI setup
  • Live demo – step-by-step Meta CAPI setup using Stape pre-built template
  • Q&A session – get expert answers to your tracking and implementation questions

✨ Who should watch:

  • Performance marketing agencies looking to improve Meta Ads attribution
  • Media buyers and advertisers struggling with data loss and tracking limitations
  • Digital marketers responsible for Meta Ads
  • Business owners who want to increase ad efficiency and scale faster

Common questions and answers

1. Do I need both client-side and server-side Meta tracking?

Best practice is to use both — Meta recommends the redundant event approach: send events from the pixel (client) and CAPI (server) with proper deduplication. This improves reliability and performance.

2. Do I need Google Tag Manager to use Meta CAPI?

If you use Meta CAPIG (Conversions API Gateway), you don’t need server GTM. But for more flexibility and customization, server GTM is preferred.

3. What’s the benefit of using server GTM via Stape vs. just setting up CAPI manually?

Stape simplifies server GTM hosting and adds features like Cookie Keeper, Custom Loader, Custom domains, and prebuilt templates. It reduces setup time and helps maintain compliance and performance.

4. Can I run Meta CAPI without GTM containers if I already set it up via Meta CAPI Gateway?

Yes — if you use CAPI Gateway, you don’t need additional GTM setup. But don’t use both (CAPI Gateway + server GTM) at the same time to avoid overreporting.

5. Can I use Stape even if my website isn’t built on WordPress?

Absolutely. Stape supports all CMSs — WordPress, Shopify, Webflow, custom code, etc. Check stape.io/meta-capi-server-gtm for setup guides by CMS.

6. Do I always need to use Data Tag to send data to the server?

We recommend using the Stape Data Tag as it works independently from GA4 logic therefore is platform-agnostic and provides additional control and reliability.

7. Can I use server-side tracking without updating the client-side JavaScript manually?

Yes — server-side setups can still rely on existing dataLayer events. You can enrich those with plugins or backend logic, but no full rewrite is needed.

8. My CAPI is set up, but costs are still high. When will I see improvement?

It varies per account, but advertisers typically start seeing performance improvements within a few weeks, especially when more accurate conversion signals are used.

9. My Advanced Matching Score is stuck at 50%. What’s wrong?

You’re likely missing user parameters (like email or phone) in some events. To reach higher figures, ensure both client and server versions of events consistently send available user data.

10. How do I track offline conversions from CRM without overreporting?

Use event deduplication (event IDs) and only send meaningful events (like Qualified Lead or Purchase). Avoid reporting the same conversion twice from different sources. 

11. Can server-side tracking improve Event Match Quality?

Yes — when properly implemented, server GTM with user data (email, phone, etc.) can boost EMQ significantly. Tools like Cookie Keeper also help with better attribution.

12. How does deduplication work with Meta CAPI?

Meta deduplicates events using event_id (also _fbp cookie as a fallback) Send the same ID from both pixel and CAPI — Meta will keep only one event and discard the duplicate.

13. Can GA4 deduplicate client and server events too?

Although GA4 attempts deduplication using transaction_id, it assumes a single data stream coming in, either via the server or the web so there’s no deduplication such as you have with Meta. Best practice: choose either server or client-side for GA4 to avoid data inflation.

14. Is there a risk of performance issues if I use many tags (one per event)?

No — having separate tags per event is a clean and manageable approach, especially with server-side tagging. It doesn’t affect page performance the way client-side tags might.

15. Can I store data (like item arrays) in cookies to enrich events later?

Yes in principle, you may need to stringify your objects though. Also consider using localStorage or session-based enrichment via the server, depending on your particular needs.

16. Can I send a webhook-triggered JSON payload to both Meta and GA4 from server GTM?

Yes — you can capture a webhook, transform the data, and route it to both Meta and GA4 using server-side tags in server GTM.

Yes. Cookie Keeper maintains user identifiers across domains, helping improve attribution when checkouts happen off your main site.

18. Are Stape tags better if I use your plugin vs. another plugin/CMS?

No — as long as the dataLayer is correctly structured, the source (plugin or CMS) doesn’t affect performance. Just make sure it contains the right data.

19. As an agency, how can we help clients who struggle with setup?

Use Stape’s CMS apps and pre-built server GTM templates to simplify implementation. You can also white-label Stape services or offer setup as a managed service.

20. How do I show performance uplift to clients after switching to server-side?

Track key metrics before and after implementation: EMQ, conversion volume, cost per result. Stape Analytics can also show recovered server-side events.

21. How can we stay GDPR/CCPA compliant with Meta tracking?

Stape supports full consent-based tracking. Make sure to integrate Consent Mode, trigger tags only after user opt-in, and use hashed PII.
