On-page SEO is everything on the page itself that helps search engines understand it and helps people choose it in the results: the title, meta description, headings, body content, images and links. This on page SEO checker reviews all of them in one pass and tells you exactly what to change.
It is the part of SEO you fully control, and usually the quickest to improve — most fixes take minutes in your CMS.
How to run an on-page check
Paste the page URL
Enter the address of the page you want to optimize.
We read the page
The checker extracts the title, description, headings, text, images and links.
Review the findings panel
See your current title, description, H1 and word count exactly as search engines see them.
Apply the fixes
Work through the list in order, then re-check the page.
The on-page elements we check
- Title tag — present, unique, about 50–60 characters, with the main topic near the start.
- Meta description — present and 140–160 characters, written as a reason to click.
- H1 heading — exactly one, describing the page’s topic.
- Heading outline — H2 and H3 sections in a logical order without skipped levels.
- Content depth — enough text to genuinely answer the query; we flag pages under 300 words.
- Images — descriptive alt text, explicit dimensions and lazy loading below the fold.
- Links — internal links to related pages and no broken links.
- Canonical and indexability — the page names itself as canonical and isn’t marked noindex.
- Social and structured data — Open Graph tags for sharing and JSON-LD that describes the page type.
On-page vs technical vs off-page SEO
On-page SEO covers the content and HTML of individual pages. Technical SEO covers how your site is crawled and served — robots.txt, sitemaps, redirects, speed and HTTPS. Off-page SEO is mostly about links and mentions from other websites. This checker covers on-page SEO in depth plus the most important technical signals, so you can fix everything that lives in your own code and content.
Writing on-page elements that rank and get clicks
Write the title for the searcher first: lead with the topic they searched for, add the benefit, and finish with your brand. Make the H1 match the promise of the title so visitors know they have landed in the right place. Use H2s that mirror the questions people ask, and answer each one directly in the paragraph below it. Describe images as you would to someone who can’t see them. Link to related pages using the words people would search for.
Quick on-page wins
- Put the most important words in the first half of your title — mobile results often cut the rest.
- Rewrite descriptions as a promise: what will the reader get, and why is your page the best place to get it?
- Add a short FAQ section that answers the questions people ask about the topic.
- Link from your strongest pages to the page you are optimizing, using a descriptive anchor.
Limits to keep in mind
We check structure and signals, not writing quality. A page can pass every on-page check and still fail to rank if its content doesn’t serve the search intent better than the competition.
Privacy and safety
The checker reads only the public HTML of the page you enter. Nothing is changed on your site, and anonymous reports are deleted after 30 days. Read our privacy policy for details.

On page seo checker: frequently asked questions
What does an on page SEO checker do?
It reviews the elements on a single page — title, meta description, headings, content, images, links and key tags — and flags anything missing, too long, duplicated or broken.
What is the ideal title length?
Around 50–60 characters. Google truncates titles by pixel width, so very long titles get cut off and are more likely to be rewritten.
Does the meta description affect rankings?
Not directly, but it affects how many people click your result, which is why a missing description is still flagged as a warning.
How many words should a page have?
There is no magic number. We flag pages under 300 words because they rarely answer a question fully, but the right length is whatever covers the topic better than the pages already ranking.
Should I use more than one H1?
HTML allows it, but one clear H1 per page makes the topic unambiguous for readers and search engines. Multiple H1s are flagged as a minor improvement.
Is on-page SEO enough to rank?
For low-competition queries it often is. For competitive ones you also need strong content and links from other sites; on-page work makes sure those efforts aren’t wasted.
