Free On-Page SEO Checker: Overview & Context

Key Features

    Validate H1, H2, and H3 structures to confirm that your content flow is logical and crawlable.

  • Metadata Compliance Scan

    Verify that title tags and meta descriptions are within standard character limits and include target keywords.

  • Alt Tag Diagnostics

    Identify images that are missing alt descriptions, improving accessibility and image search potential.

  3. Apply the recommended structure updates to your CMS or codebase.

Frequently Asked Questions

  • Why is a correct heading structure important?

    Search crawlers use heading tags (H1-H6) to understand the topic hierarchy of a page. Out-of-order headings can make it harder to parse your content.

  • What is the ideal meta description length?

    Meta descriptions should ideally be between 120 and 160 characters to avoid truncation in standard search result snippets.

  • Can I run this on local files?

    This tool audits public, reachable web URLs. For local files, verify preview builds in your staging environment.
