Meta tag checker
See how any page is likely to look in Google and Bing search results, whether its title and description will be cut off, and which tags need fixing.
What the checker looks at
Title and description
Whether they're set, and how wide they are in pixels, which is what Google and Bing actually cut by. Character counts are only a rough guide.
Indexing rules
noindex, nofollow and nosnippet in the robots meta tags, the googlebot and bingbot tags, and the X-Robots-Tag header.
Canonical address
That there's exactly one canonical tag and that it points where you expect, not to another page or another site.
Language versions
If the page uses hreflang, that the codes are valid, the page lists itself and there's an x-default.
Structured data
Which JSON-LD types are in the head, and whether any blocks are broken and would be ignored.
The basics
Viewport for phones, character set, page language, site icon, HTTPS and redirect chains.

What is a meta tag checker?
It reads the tags in a page's head that search engines use, such as the title, meta description, robots and canonical tags, and shows how the page is likely to appear in search results. It also flags anything missing or set up wrongly.
How long should a title tag be?
Google shows about 600 pixels of a title on desktop, which is usually 50 to 60 characters. Wide letters like W and M use more space than narrow ones like i and l, so the checker measures in pixels rather than counting characters.
How long should a meta description be?
Aim for roughly 120 to 160 characters. Google shows about two lines on desktop and a little more on mobile, and cuts the rest. Put the most important point first so it survives the cut.
Why does Google show a different title or description?
Google rewrites titles and descriptions when it thinks other text on the page matches the search better. A clear, accurate title and a description that genuinely sums the page up make that less likely, but it can't be prevented completely.
What's the difference between this and the OG checker?
This checker is about search results. The OG checker is about link previews when a page is shared on social networks and chat apps, which use the Open Graph and X tags instead. Most pages need both sets of tags.
Does the checker see everything on the page?
It reads the page's head, which is where meta tags belong. Tags added later by JavaScript, and structured data placed in the body, won't be picked up. Use Google's Rich Results Test, linked from your results, for a full structured data check.
Are the results cached?
Yes, for about an hour, so repeat checks are instant. Press Check again after changing your page to fetch a fresh copy.
