About this tool

Background

On-page meta tags still matter. The title and meta description are what Google shows in the search snippet (when it doesn't rewrite them). The H1 reinforces topical relevance. The canonical tag tells search engines which URL is the authoritative version of the page when duplicates exist. Get any of these wrong (too long, too short, missing, or pointing somewhere unexpected) and you leave clicks on the table.

This tool reads the page metadata from our web index, so it shows what Google's crawler most recently saw, not necessarily what your CMS thinks it's serving. That distinction matters: client-side rendering bugs and stale CDN caches often mean the indexed tags differ from the live HTML.

How it works

Submit any URL. We look it up in our latest index (3 billion+ pages) and return the four highest-leverage on-page tags, with character-count warnings flagging anything that's too short, too long, or missing.

Length recommendations: titles 30–60 characters, meta descriptions 70–160 characters. These are pixel-budget approximations (Google truncates at ~580px for titles and ~990px for descriptions on desktop), so a 55-char title with wide letters can still get cut off. Always preview live where it matters.
