Meta Tags Checker

Check any page's title, meta description, canonical URL, Open Graph, and Twitter Card tags, with truncation warnings and missing-tag alerts.

About this tool

This tool fetches a page once and reads its title tag, meta description, canonical URL, H1 heading, and Open Graph and Twitter Card tags directly from the page's HTML. Title and description length is shown both as a character count and as an estimated rendered pixel width, since Google truncates search result snippets by how wide the text actually renders, not by a fixed number of characters. The pixel width shown is an estimate based on typical letter widths, not an exact match to Google's own rendering, since that depends on the specific device and font in use.

Frequently asked questions

Google truncates title and description text in search results based on how wide the text renders on screen, not on a fixed character count. A title made mostly of narrow letters like "i" and "l" can fit more characters than one made of wide letters like "m" and "w" before it gets cut off. A character count alone can make a title look safe when it would actually be truncated, or the opposite.
No, it is an estimate. There is no way to measure the exact rendered width without a real browser using the exact font Google renders with, which can also change over time and vary by device. The estimate uses typical letter widths for a common search-result font and is meant as a useful guide for spotting titles and descriptions that are clearly too long, not as a pixel-perfect prediction.
Missing title, missing meta description, more than one title or description tag, more than one H1 heading, a title that exactly matches the H1, a missing canonical URL, and missing Open Graph or Twitter Card tags. Each of these is a common, fixable issue, not necessarily a serious error, and some pages may have good reasons for one of them, so use the list as a checklist to review rather than a strict pass or fail.
They control how a page looks when it is shared as a link on social platforms and messaging apps: the preview title, description, and image. Without them, platforms usually fall back to the page's title and meta description and may show no image at all, which is why missing tags are flagged even though they are not required for search engines themselves.
No. Like the other tools on this page, it reads the raw HTML returned by the server. Meta tags, titles, and Open Graph tags are almost always present in the initial HTML even on JavaScript-heavy sites, since that is what search engines and social platforms also rely on, but a tag injected only after client-side JavaScript runs would not be seen here.
No. The address is used to fetch the page for that one check and is not saved. Only public web addresses can be checked: requests to private or internal network addresses are refused.
