Are click IDs case-sensitive?
Yes. Treat parameters exactly as the platform documents them (fbclid, not FBCLID) to avoid filtering.

How to Debug Click ID Loss
Click IDs such as fbclid, gclid, and ttclid tie ad platform optimization to actual conversions. When those IDs vanish, bidding algorithms lose signal and CPAs spike overnight.
Debugging click ID loss means tracing every redirect, script, and form handoff that touches the URL so you can preserve the identifier through to the CRM.
Why click IDs disappear
Some trackers rewrite URLs with their own query parameters and accidentally drop the click ID. Browser privacy settings and meta refreshes can also wipe IDs because the next page loads from a clean URL.
Manual actions?like a sales rep copying a landing page URL from the address bar without its query string?remove the click ID before it ever reaches backend systems.
How to detect click ID loss
Use a redirect checker plus the Click ID Extractor to observe whether the ID exists at every hop. Compare CRM or analytics entries against ad platform logs to see where the value first went missing.
Inspect browser dev tools for script-based rewrites and inspect server logs for truncated URLs. The moment the ID disappears, document which system touched the URL.
How to fix click ID tracking
Propagate click IDs through hidden form fields or first-party cookies so even if the URL changes, backend systems retain the value. Configure trackers to treat click IDs as reserved parameters that cannot be removed.
Educate teams on how to share links without stripping parameters and automate QA checks whenever landing pages or smartlinks change.
FAQ
Click ID FAQ
Can I store click IDs in cookies?
You should. First-party cookies keep the ID safe even if the user refreshes the page without query parameters.
What if privacy tools block click IDs?
Implement both URL-based and server-side capture so you have redundant identifiers when browsers strip tracking parameters.
