Free On Page SEO Checker

This free on-page SEO checker reads a single page the way a search engine does and grades the elements you control directly: title tag, meta description, H1 and heading outline, keyword coverage, image alt text, internal and external links, and whether the content is deep enough to answer the query it targets.

On-page elements the checker grades

• Title tag - presence, length, uniqueness and keyword placement.
• Meta description - length, clarity and whether it sells the click.
• Heading structure - one descriptive H1 and a logical H2-H6 outline.
• Keyword coverage - whether the focus term appears in the title, H1, intro and body without stuffing.
• Images - missing alt text, oversized files and uncompressed formats.
• Links - internal links that pass context, broken links and thin anchor text.
• Content depth - word count, section count and whether the page answers the query in full.
• Snippet readiness - Open Graph tags, structured data and FAQ markup that earn rich results.

How to fix on-page SEO issues in priority order

Fix the title and H1 first because they carry the strongest relevance signal, then repair the heading outline so each section answers one sub-question, then add or trim body content to cover the query fully, and finally clean up images, alt text and internal links. Re-run the checker after each change so you can see the score move.

On-page SEO vs. technical SEO

On-page SEO is what sits inside the page: copy, headings, metadata and links. Technical SEO is how crawlers reach and interpret it: indexability, canonicals, robots rules, sitemaps, speed and rendering. A page needs both, so run the on-page checker alongside the technical audit.

Frequently asked questions

What does an on-page SEO checker do?

It analyses the elements of a single page that affect relevance and click-through, then scores each one and lists the specific fixes, such as a missing H1, a title that is too long, or images without alt text.

Is the on-page SEO checker free?

Yes, and it exports the full result list as CSV without an account, so you can hand findings to a writer or developer.

How many words should a page have to rank?

There is no universal number. The page must fully answer the query, so compare your coverage against the ranking pages for that exact term rather than chasing a fixed word count.

Does keyword density matter?

Only as a sanity check. Modern systems reward topical coverage, so use the term naturally in the title, H1, first paragraph and subheadings, then cover related entities instead of repeating the phrase.

Can I check a page that is not published yet?

The page must be publicly reachable, so preview links on staging that allow crawler access work too. Localhost and private network addresses cannot be checked.

Does the checker look at mobile performance?

It reports load time, page weight and viewport configuration, and flags render-blocking assets that hurt mobile users most.
