Meta tags checker

One check for the tags search engines and social platforms read: <title>, meta description, canonical, robots, Open Graph and Twitter cards, with a Google snippet preview.

Search tags vs share tags

Google builds search results from the <title> and meta description (and rewrites them when it thinks they don’t match the query). Social platforms build cards from og: and twitter: tags. They can say different things: a title tag with “| Brand” for search and a punchier og:title for feeds is normal and fine.

  • Title: Google truncates by pixel width, around 580px, which is roughly 50–60 characters.
  • Meta description: shown up to about 155–160 characters on desktop, less on mobile.
  • Canonical: one absolute URL per page, matching og:url.
  • Robots: make sure a stray noindex isn’t left over from staging.

Frequently asked questions

Do meta keywords matter?

No. Google has ignored the keywords meta tag for ranking since at least 2009. You can leave it out.

Why does Google show a different title than mine?

Google rewrites titles it considers too long, stuffed with keywords or not matching the page. Keep titles descriptive and under about 60 characters, and make sure the H1 agrees with the title.

Is og:title the same as the title tag?

No. The title tag is for browsers and search engines; og:title is for social cards. If og:title is missing, platforms fall back to the title tag.
