Read every meta tag on any page in seconds: title, description, canonical, robots, Open Graph, X cards, hreflang and schema. See Google and social previews and a clear fix for each problem.
Meta tags are hidden from visitors but read by search engines and social networks. They decide how your page looks in Google, whether it can be indexed, which URL is the main version and what shows when someone shares your link. One wrong robots tag can remove a page from Google, so checking them is a key part of any SEO audit.
