SEO Check
The SEO check tool analyzes a webpage's on-page SEO elements and reports findings for each factor: title tag length, meta description, canonical URL, robots meta tag, Open Graph tags, heading structure, image alt attributes, and structured data. It provides actionable feedback for each check, helping developers and webmasters identify and fix common SEO issues without a paid tool.
What is the SEO Check Tool?
The SEO check tool fetches a webpage and inspects its HTML for on-page optimization signals that search engines use to understand and rank content. It checks the title tag (presence, length, keyword placement), meta description (presence and length), canonical link tag, robots meta directives (index/follow), Open Graph and Twitter Card tags, heading hierarchy (H1 uniqueness, H2-H6 structure), image alt text coverage, and the presence of structured data (JSON-LD or microdata). Each check is rated as pass, warning, or fail with an explanation.
How does it work?
Enter the URL of the page you want to analyze. The tool fetches the page HTML server-side (bypassing CORS restrictions), parses the document, and evaluates each SEO factor against best practice thresholds. Results are grouped by category — meta tags, social sharing, content structure, and technical SEO — and each finding includes a description of the issue and a recommended fix. A summary score gives an overall indication of on-page SEO health.
Typical Use Cases
- Auditing a newly published blog post for basic on-page SEO completeness
- Verifying that Open Graph tags are correctly set before sharing on social media
- Checking for duplicate H1 tags or missing alt text after a CMS migration
- Confirming that a page has the correct canonical URL and robots directives
Step-by-step Guide
- Step 1: Enter the full URL of the page to analyze.
- Step 2: Click Analyze to fetch and inspect the page.
- Step 3: Review each check in the results panel, noting warnings and failures.
- Step 4: Fix the identified issues in your CMS or source code and re-run the check.
Example
Input
https://example.com/blog/my-article
Output
Title: OK (52 chars) | Meta desc: Warning (missing) | H1: OK | Canonical: OK | OG tags: Fail (og:image missing)
Tips & Notes
- Keep title tags between 50–60 characters to avoid truncation in Google search results.
- Every page should have exactly one H1 tag that describes the main topic of the page.
- Use JSON-LD for structured data rather than microdata — it is easier to maintain and is Google's preferred format.
Frequently Asked Questions
Does the SEO check tool guarantee Google ranking improvement?
No. On-page SEO is one of many ranking factors. This tool checks technical on-page elements that affect crawlability and relevance signals, but rankings also depend on backlinks, content quality, site speed, Core Web Vitals, and many other factors.
Can I check pages that require authentication?
No. The tool fetches pages as an anonymous public visitor. Pages behind login walls or that require specific cookies will not be accessible and will return an error or redirect to a login page.
