Meta tag checker
Enter any URL and we’ll fetch the live page and show its real title, meta description, canonical, Open Graph, and Twitter tags — with length and quality checks.
One page checked — audit the whole site.
atlookup crawls every page and flags title, description, canonical, OG, and structured-data issues in one prioritised report. Free to start.
What this checker does
Enter a URL and we fetch the live HTML server-side, then read the exact tags Google and social platforms use: the <title>, meta description, canonical link, robots directive, Open Graph and Twitter cards, the page’s <h1>, and its language. You get the real, rendered values — not what you think is on the page.
What the checks mean
- Title / description length — flagged when too long (likely truncated) or too short (missed opportunity).
- Canonical — confirms the page declares its preferred URL.
- Robots noindex — warns if the page is telling search engines to skip it.
- H1 count — flags zero or multiple H1s.
- Open Graph — warns when social-share previews would look plain.
Notes
We fetch the raw HTML, so JavaScript-rendered tags (added after page load) may not appear — the same way many crawlers see your page first. The checker only fetches public pages and is rate-limited to keep it fair for everyone.
