Fireshift / Help / No container found
Why the scan says "no container found"
We give no score when the homepage, /pricing, /signup and /demo load no public Google Tag Manager or Google tag container we can read. The usual reasons: tags load only after cookie consent, the container is served from your own domain (server-side GTM), the site loads tags through Segment or another tool, or the site blocks automated requests. A live browser visit usually settles which it is.
The usual reasons
| Reason | How to tell | What we do |
|---|---|---|
| Tags wait for consent | Page source has no GTM- until you accept the banner | A live visit accepts the banner and logs what fires |
| First-party (server-side) GTM | The script loads from your own subdomain, not googletagmanager.com | The live visit flags "tag script loads from a first-party host" |
| Segment, Tealium or a CMP loads the tags | Page source shows analytics.load( or the vendor's script | Live hits still show what reaches Google and Meta |
| The site blocks automated requests | We get an error or a challenge page | We report it. We don't use bot-detection workarounds. |
| No Google tags at all | Nothing in source and nothing in the Network tab | Nothing to score |
In our 5 Nov 2026 study, 1,298 of 1,727 sites (75.2%) served a container we could read. The rest fell into the rows above.
Check it yourself
- View source on your homepage and search for
GTM-andgtag. - Open DevTools, Network, reload, and filter on
gtm. Note the host the script comes from. - Accept the banner and look again.
If you see a container we missed, reply to the scan email with the ID and we'll rerun it.
FAQ
Does server-side GTM break the scan?
Partly. The web container is still read if it is public; events your server sends on its own are invisible from outside.
Will you try harder to get past a block?
No. We don't evade bot detection. If you own the site, you can allowlist the scan or send us the container ID.
