On Page SEO Grader
An on-page SEO grader is a tool that checks a URL's page-level SEO signals and returns a score plus prioritized recommendations for improvement.
Key takeaways
- An on-page SEO grader gives a quick diagnostic score (0–100) for a single URL.
- It checks 20+ factors like title tags, meta descriptions, headings, and internal links.
- Use it to prioritize fixes, not as a guarantee of rankings.
- Best results come when you pair it with a target keyword.
- Don't rely solely on the grader; also consider search intent and content quality.
It helps SEO practitioners quickly spot page-level issues that may affect relevance, crawlability, and rankings, then turn them into a fix list.
What People Use It For
- Diagnose page issues: Identify problems with title tags, meta descriptions, headings, content length, internal links, canonical tags, image alt text, and indexability.
- Get a score: Receive a 0–100 score that summarizes page optimization level.
- Prioritize fixes: Use the action checklist to address the most impactful issues first.
- Compare against a keyword: Enter a target keyword to see how well the page is optimized for it.
- Track improvements: Re-run the grader after changes to see score improvements.
Quick Workflow
- Enter the URL of the page you want to analyze.
- Add a target keyword (optional but recommended for context).
- Run the analysis – the tool checks 20+ on-page factors.
- Review the score and read the prioritized recommendations.
- Implement fixes – start with the highest-priority items.
- Re-run the grader to confirm improvements.
When Not to Start Here
- Full site audit needed: Graders analyze one URL at a time; use a site crawler for bulk checks.
- Technical SEO issues: Graders focus on page-level signals, not server errors, site speed, or structured data.
- Keyword research first: You need a target keyword to get the most value from the grader.
- Content strategy: Graders don't assess search intent or content quality deeply.
