Meta tag checker
The meta tag checker is a free tool that requests one page with no JavaScript and shows the title, description, canonical, Open Graph, X card and structured data that crawlers receive, with a fix for each problem.
One request to the page you enter. Nothing is stored.
Add structured data
No JSON-LD on the page? Write it in a minute with the free generator.
Check what AI crawlers get
Tags and files only help when crawlers can read the page. The free scan requests your pages as GPTBot, ClaudeBot, PerplexityBot and CCBot and shows what arrives.
Questions
What does the meta tag checker read?
It requests your page once, with no JavaScript, and reads the title, meta description, canonical link, robots and viewport tags, the html lang attribute, H1 headings, Open Graph and X (Twitter) tags, hreflang links and JSON-LD types.
Why does it say my title is missing when I can see it in the browser?
Your site probably sets the title with JavaScript after the page loads. The checker, like most AI crawlers, does not run JavaScript. Set the tags in the HTML the server sends.
How long should a title and description be?
Keep the title under about 60 characters and the description between 70 and 160 characters. Longer text is often cut in search results.
Do meta tags affect AI answers?
AI search tools use the title and description to label and summarize a page, and Open Graph tags shape link previews in chat apps. The page text still matters most.
