What an on-page SEO checker looks at
On-page SEO is everything you control inside one page: its title, meta description, headings, text, images, links and the tags that tell search engines how to treat it. This free on page SEO checker loads the page the way a search engine does and reads those basics in a few seconds. It gives you a score out of 100, the heading outline, the images that miss alt text and a list of findings sorted from the most serious to the least.
Why these basics matter
A missing title, a stray noindex tag, two H1 headings or images without descriptions rarely show up when you look at a page, yet they can keep it out of search results or weaken how it appears. Most of them take a minute to fix once you know they are there. Every warning in the report comes with a short, plain-language tip.
How to use it
- Paste the address of one page, with or without https://.
- Press “Check this page” and read the score, then the findings marked “Fix” and “Improve”.
- Follow the tip under each finding, then run the check again to see the score rise.
Tip: check your most important pages first, such as the home page, your main service pages and the pages that bring the most visitors.
