How this service works
Does a website use Google Tag Manager? Fetches the page (homepage for a bare domain) and matches Google Tag Manager's fingerprints in the HTML and response headers, returning yes/no with the evidence snippet and the category (tag-manager). Technographics for sales, competitor research and migration planning, one technology per call. $0.01 per check.
Output
Returns a yes/no boolean indicating whether Google Tag Manager is detected on the site, an evidence snippet from the HTML or response headers that matched the GTM fingerprint, and the technology category label ('tag-manager').
Example use cases
Competitor technographic research
“I'm building a sales list and want to know which of our competitors use Google Tag Manager — can you check if acme.com has GTM installed?”
Pre-migration GTM audit
“We're about to migrate our client's analytics stack — can you confirm whether their site clientsite.com is currently running Google Tag Manager?”
Sales prospecting qualification
“I'm qualifying leads for our tag management product — can you check if prospectdomain.com uses Google Tag Manager so I know whether to pitch a migration or upsell?”
Technical details
Endpoint
GEThttps://site.intel.rallylive.ca/site/uses/google-tag-manager?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, low-cost ($0.01) single-domain check for Google Tag Manager specifically. It is ideal for sales intelligence workflows, pre-migration audits, or technographic profiling where you need a definitive yes/no with evidence rather than a full technology stack scan. For bulk checks across many domains, prefer the sibling bulk endpoint.
Side effects
- Domain is unreachable or returns a non-200 status, resulting in an error or inconclusive result
- The website blocks crawlers or returns a bot-detection page, causing a false negative
- The site uses a server-side GTM setup not detectable from HTML or standard headers
- Rate limiting or network timeouts prevent the page from being fetched
