What this tool does
Enter a URL and the tool reads the page’s HTML and reports on its title, meta description, robots tag, canonical link, viewport tag, the H1 headings and how many H2s there are. It flags lengths and problems such as a missing title or more than one H1.
What to look for
- Title. Roughly 50 to 60 characters is a good guide. Much longer risks truncation in results, and very short titles waste space.
- Meta description. Around 120 to 160 characters. It doesn’t affect rankings directly, but it can affect whether someone clicks.
- H1. One clear H1 that describes the page is the usual advice. Multiple H1s are allowed by HTML5, but a clear single one is easier to reason about.
- Robots. Make sure a live page doesn’t carry
noindexby accident. A leftover from staging is a classic mistake. - Canonical. It should point to the preferred address of this page.
- Viewport. Needed for the page to render properly on phones.
Limits
The tool reads the HTML with simple patterns. That is quick, but a tag written with an unusual attribute order or built by JavaScript can be missed. If the tool says a tag is missing and you know it is there, view the page source to confirm.
It checks what’s on the page, not whether the content is good. A perfect set of tags doesn’t make a page rank, and an imperfect one doesn’t stop it. Use it as a checklist before publishing.
The request comes from this site’s server and results are cached for 10 minutes. Up to 12 checks a minute are allowed. To see how a title and description may look in results, use the SERP preview.
Why does it report a missing tag that I can see in my source?
The tool reads tags with simple patterns, so an unusual attribute order or a tag injected by JavaScript can be missed.
Is more than one H1 wrong?
HTML allows it, but one clear H1 per page is the common recommendation and easier to maintain.
Does meta description length affect rankings?
Not directly. It affects how the snippet looks, which can influence clicks.
Will it check my images or page speed?
No. It only audits the tags and headings listed above.
What does it report about headings?
It lists the H1 headings found on the page and counts the H2 headings. It does not audit the whole heading outline.
