UTM and redirect monitoring

A landing page can load while the campaign tracking disappears

UTM parameter monitoring compares the tracking keys submitted with a campaign URL against the final destination after redirects, exposing attribution loss that an ordinary uptime check can miss.

Two kinds of health

HTTP 200 does not mean the campaign is still attributable

The destination can load normally while a redirect drops utm_campaign or another submitted parameter. Visitors see a page, but reporting loses the context used to connect the visit to the campaign.

What is compared

Bifro checks submitted UTM parameter names through the chain

The check follows the URL to its final destination and reports which submitted UTM names are missing. It does not inspect analytics events, pixels, conversion tags, or Google Analytics configuration.

  • utm_source
  • utm_medium
  • utm_campaign
  • utm_content and other submitted UTM keys

What to do

Find the redirect that changed before rewriting the campaign

Confirm the original campaign URL, inspect each redirect hop, compare the final query string, and correct the redirect or destination rule that removed the required key. Then run a manual check to confirm recovery.

Clear answers

Questions agencies ask

Can a redirect remove UTM parameters?

Yes. A redirect target can omit the original query string or rebuild it without one or more submitted UTM keys.

Does Bifro Check verify analytics events?

No. It verifies whether submitted UTM parameter names remain present at the final URL; it does not inspect analytics or pixel events.

Can I check a link manually?

Yes. The public checker offers a point-in-time check, and monitored links include a manual check action in the application.
