Which tags slow down your site?
Finds every third-party script on the page (tag managers, analytics, pixels, chat widgets, A/B tools), measures each one and ranks them by the load time and bytes they cost. You see which tags are worth it and which are dead weight from a vendor you stopped paying.

Go to opsblu.comWhat we check
- Every third-party script and the vendor behind it
- Bytes transferred per tag, including what it loads in turn
- Time to fetch and whether it blocks rendering
- Duplicate tags (two GA4 configs, two pixels)
- Tags loaded in the <head> synchronously
- Total third-party weight versus your own code
Cost of one run: 1 fetch + script timing. Results for the same URL are kept for a few minutes, so running twice is free and instant.
Questions
How many tags is too many?
There is no fixed number, but every tag is a network round trip and often more. Pages with more than 15 third-party scripts usually spend longer loading tags than content. Each should have a named owner who can say what it is for.
Does moving tags server-side help?
Yes. Server-side tagging sends one request from the browser and fans out to vendors from your server, so the page loads one script instead of a dozen and ad blockers see less. That is what TagFrog does.
Why do pixels load twice?
Usually one is hard-coded in the theme and one fires from the tag manager. Both count the same conversion, your ad platforms over-report, and the page pays for both. Remove the hard-coded one.
