Google Tag Manager
Generate official GTM install snippets from your Container ID, copy the head and body code, then optionally verify the tag on a live URL.
Enter Your GTM Container ID
Paste your Google Tag Manager Container ID to generate the install code.
Verify Installation (Optional)
Check a public URL (or paste HTML) for the GTM head script and noscript iframe.
Many sites allow Googlebot but block other server fetches. If URL check fails, open the page in your browser, View Page Source, and use Paste HTML — that check is still valid.
Frequently Asked Questions
Google Tag Manager is a free browser-based tool on Neemtools. Use it instantly with no install or account required.
It generates the official GTM head and body install snippets from your Container ID (GTM-XXXXXXX) and can check a public URL or pasted HTML for those snippets.
Put the head snippet as high as possible in the page <head>. Put the noscript iframe immediately after the opening <body> tag on every page that should load the container.
In Google Tag Manager, open your account and container. The ID appears at the top of the container workspace and looks like GTM-XXXXXXX.
Google Tag Manager (GTM-XXXXXXX) and gtag.js (G-XXXX / AW-XXXX) are different. Many sites install Analytics and Ads with gtag only. This tool’s install snippets are for a GTM container. The checker now reports gtag/GA4/Ads when those are present, even if no GTM container is found.
Your browser and Googlebot are trusted visitors. Neemtools checks from a server fetch, and Cloudflare/WAF often blocks that. Open the page yourself, View Page Source, paste the HTML, and run Check Paste — that is a correct verification.
Tag Assistant runs in your browser on the live page. Our URL check uses a server-side fetch that many sites block. Prefer Tag Assistant for live firing checks, or paste HTML here to confirm the snippets are in the source.
No. Code generation runs in your browser. URL checks only fetch the page through the SEO proxy to scan HTML and are not used to store your tags.
