How to use the on-page SEO checker
An on page SEO checker looks at one page at a time and tells you what Google actually sees. This one checks your title and description the way Google cuts them, plus headings, alt text and whether the page can be indexed at all.
- Paste the page URL or drop the HTML into the box above.
- Run the check to see title length, description length, headings and alt text.
- Fix the flagged items on your page, then check again to confirm.
When to run a page check
- Before you publish a new page, to catch a missing title or description.
- After a redesign, to check headings and alt text survived the move.
- When a page stopped showing up in Google search, to see if it is set to noindex by mistake.
- Before you promote a landing page, so the meta description reads well in search results.
What you get
The result shows your title and meta description at the length Google actually uses, so you know if they will be trimmed in search results. It lists every heading on the page so you can see if the h1 is missing or duplicated, checks which images are missing alt text, and tells you if the page is set to noindex or otherwise blocked from Google.
Good to know
This on page SEO tool checks one page at a time, not a whole site — paste a new URL for each page you want to review. It looks at what is already on the page; it does not check backlinks, page speed or keyword rankings.
Questions people ask
What does an on page SEO checker actually check?
It checks your title and meta description at the length Google shows them, the heading structure including the h1, missing alt text on images, and whether the page is indexable or set to noindex.
Is this on page seo checker free to use?
Yes. There is no account and no watermark, and it runs on our own servers.
What is a noindex tag and why does it matter?
A noindex tag tells Google not to show the page in search results. It is sometimes switched on by mistake through a plugin or a CMS setting, so it is worth checking on any page that should be ranking.
Why does my title get cut off in Google search results?
Google shows a limited width for titles, so longer ones get truncated with three dots. The checker shows you the cut point so you can trim the title before it happens.
Do I need to sign in to check a page?
No. There is no account needed, and the file you upload is deleted from our servers within an hour.
What is alt text and why does the checker flag it?
Alt text describes an image for screen readers and for Google image search. The checker flags images with no alt text so you can add it.
