Enter any page address to check its title tag, meta description, canonical URL, robots rules, Open Graph tags, headings, images and structured data. You get a score, a preview of how the page looks on Google and when shared on social media, and a plain-language list of what to fix.
| Tag | Recommended length | Why |
|---|---|---|
| Title tag | About 30 to 60 characters | Longer titles are cut off in search results |
| Meta description | About 70 to 160 characters | Longer descriptions are truncated |
| H1 heading | One per page | States the topic of the page clearly |
| og:title | Up to about 70 characters | Shown when the link is shared |
| og:image | 1200 × 630 pixels | Gives a sharp preview on social networks |
Meta tags are snippets of HTML in a page's head that describe the page to search engines and social networks. The most important are the title tag and the meta description, which usually form the headline and summary shown in Google results.
Aim for about 30 to 60 characters. Google shows roughly the first 600 pixels, which is about 60 characters, and cuts longer titles with an ellipsis. Put the most important words first and keep each title unique across your site.
About 70 to 160 characters. Google often rewrites descriptions, but a clear, accurate one that matches the search increases the chance your version is used and the chance people click.
The title tag is a real ranking signal. The meta description is not a direct ranking factor, but it affects click-through rate. Other tags, such as canonical and robots, control which version of a page is indexed and whether it is indexed at all.
A canonical tag tells search engines which URL is the preferred version of a page when the same content is reachable at several addresses. It prevents duplicate-content confusion and consolidates ranking signals on one URL.
Open Graph tags (og:title, og:description, og:image and others) control how a link looks when shared on Facebook, LinkedIn, WhatsApp, Slack and similar apps. Without them the preview can be plain or wrong.
Yes. We only read what is publicly visible on the page, the way a search engine does. We do not store the page, and private or internal addresses are blocked.
