Understanding Click IDs (fbclid, ttclid, gclid) in Server-Side Tracking
In the evolving landscape of digital privacy, traditional client-side pixels are losing up to 30% of their data due to ad-blockers, iOS 14+ restrictions, and the phasing out of third-party cookies. To maintain marketing efficiency, Server-Side Tracking (SST) has become the industry standard.
This generator is designed to help developers and marketers verify that their Cloud Server handshake is correctly identifying and storing the unique click identifiers sent by ad platforms.
What is an FBCLID?
The Facebook Click ID (fbclid) is a parameter that Meta appends to your destination URL whenever someone clicks an ad. When a user lands on your site, the ServerTrack snippet captures this ID. If your server-side setup is correct, this ID is sent back to Meta via the Conversions API (CAPI), allowing Meta to match the event to a specific user, even if the browser pixel is blocked.
Why Test with a Link Generator?
Normally, you would have to spend real money on ad clicks to see if your server is capturing these parameters. Our tool simulates a high-intent click by appending a unique ST_TEST_XXXX identifier. By clicking these generated links, you can:
- Verify Deduplication: Ensure your server and browser events share the same ID.
- Check Cookie Persistence: Confirm the ID is stored in a first-party cookie.
- Validate Match Quality: Increase your Event Match Quality (EMQ) score in Events Manager.
Pro Tip: The Power of First-Party Cookies
When using ServerTrack, we convert these incoming Click IDs into First-Party HTTP-Only cookies. Unlike standard Javascript cookies that expire in 7 days on Safari, our server-side cookies can persist longer, ensuring that a user who clicks an ad today but buys in 14 days is still attributed to your campaign.
How to use these test results
- Generate: Enter your site URL and generate the links.
- Navigate: Click the 'Test URL' to visit your site.
- Inspect: Open your browser's Developer Tools (F12) > Application > Cookies. Search for
_fbpor_fbc. - Confirm: Check your ServerTrack dashboard to see if the event reached our processing engine with the generated ID.
