Meta Tag Analyzer
Reads common metadata from returned HTML and approximates a search-result preview.
We fetch the page for you. Our server fetches the public address you enter and reads the response. Nothing you enter is stored. Free, no account.

RankBrain rewrites the titles and descriptions that get cut off, across every template.
RankBrain works on websites built in code, through the AI tool you already use (Cursor, Claude Code, Codex, ChatGPT).
How it works
You have written a title and a description and you want to know what a search engine reads. This tool fetches the page, lists supported metadata from its head and approximates desktop and mobile search previews. It measures the title and description in pixels, so you see where the text gets cut.
- 1
We fetch the address and read its head: title, meta description, canonical, robots, viewport, charset, language, hreflang, Open Graph and X card tags.
- 2
Title and description are measured in pixels as well as characters, because search results cut text by width. A title full of wide letters is cut sooner than its character count suggests.
- 3
The preview shows the title and description as a desktop and a mobile result would display them, cut where they would be cut.
What it does not do
Search engines sometimes rewrite titles and descriptions. The preview shows what you asked for, not what they may choose to show.
Tags added by JavaScript after the page loads are not read.
When a source is busy or a site does not answer, this tool says so. It never fills the gap with a guess.
Questions
Why does my title get cut even though it is under 60 characters?
Search results cut the title by width, not by character count. A title built from wide letters, such as capitals and m or w, fills the space sooner than its character count suggests. This tool measures your title in pixels and shows where the cut lands. The preview shows what you wrote, and search engines may rewrite it later.
Why can't I see the tags my JavaScript adds?
The tool reads the HTML as it is fetched from the server. It parses the head of that response and stops there. Tags that a script inserts after the page loads, in the browser, are not in that response, so they are not listed. A crawler that does not run scripts sees the same thing you see here.
What does the canonical tag do, and do I need one?
A canonical tag names the version of a page you want search engines to treat as the main one, which matters when the same content is reachable at more than one address. The tool shows whether the page has one and what address it points to. It does not decide which address should be canonical for you.
