Meta tag checker

• Title tag and meta description: present, unique, and how long they are.
• Canonical URL: present, self-referencing or pointing elsewhere, conflicting duplicates, and canonicals placed outside <head> (which search engines ignore).
• Indexing directives from both the robots meta tag and the X-Robots-Tag HTTP header.
• Open Graph and X (Twitter) card tags used for link previews.
• Viewport (mobile rendering and zoom), page language and character encoding.
• Heading outline (H1–H6) and images without alt text.

Search engines truncate titles and snippets by display width, not by a fixed number of characters, and they often rewrite snippets to match the search. Studio flags titles over about 65 characters and descriptions over about 170 as likely to be shortened. Treat these as hints, not rules: a slightly long title with the important words first is usually fine.

• Duplicate titles or descriptions: usually two SEO plugins, or a theme and a plugin, both printing tags. Turn the feature off in one of them.
• Unexpected noindex: check the page settings in your SEO plugin, the CMS's "discourage search engines" option, and any X-Robots-Tag header added by the server or CDN.
• Canonical pointing elsewhere: correct for duplicate content; a mistake if every page points at the home page, which some misconfigured themes do.

• Studio reads the HTML the server sends and does not run JavaScript. Tags added in the browser by JavaScript frameworks are not seen here, though search engines may see them after rendering.
• Only the first 2 MB of HTML is analyzed.
• "Indexable" means nothing on the page asks search engines not to index it. It does not mean the page is indexed; use Google Search Console's URL Inspection for that.
