What is a free SEO audit tool?

A free SEO audit tool crawls your website and identifies issues that prevent you from ranking on Google — missing meta descriptions, broken links, no schema markup, slow load times, and more. The problem with most tools is that they hand you a report and leave you to fix everything manually.

Peak Visibility is different. Instead of a checklist alone, you get implementation drafts — sitemap.xml, robots.txt, meta tags, JSON-LD structured data, and Open Graph tags. Review the drafts against your live pages and CMS before deploying them.

Why most free SEO audit tools fall short

Tools like Screaming Frog (free tier), Ahrefs Webmaster Tools, and Google Search Console are powerful — but they require you to interpret the data and implement fixes yourself. For a developer or agency, that's fine. For a small business owner or freelancer on a deadline, it's an extra 10–20 hours per project.

The typical workflow with a traditional audit tool:

  1. Run the audit
  2. Read the 40-page report
  3. Manually write meta titles for every page
  4. Figure out which schema type applies to each page
  5. Build a sitemap by hand
  6. Wonder if you did it right

With Peak Visibility, that workflow becomes: paste URL → download ZIP → review recommendations → validate → deploy approved changes.

What Peak Visibility generates for free

  • sitemap.xml — Every page discovered during the crawl, formatted for Google Search Console submission
  • robots.txt — Correct directives so crawlers index the right pages
  • meta-tags.html — Optimized title and description for each page, under the character limit
  • schema-markup.html — JSON-LD structured data (LocalBusiness, Article, Product, FAQ, etc.) matched to each page's content
  • opengraph.html — og: and Twitter Card tags for every page so social shares look great
  • Peak Report — A confidence score per page showing exactly what was generated and why

The free plan covers 5 pages per scan — enough to get a complete SEO package for a landing page, portfolio, or small site.

How to use the results

Once you download your ZIP, deployment takes about 10 minutes:

  1. Drop sitemap.xml and robots.txt into your site root
  2. Submit your sitemap URL to Google Search Console
  3. Copy the per-page <head> blocks from meta-tags.html into each matching page
  4. Paste the JSON-LD from schema-markup.html into each page's <head> or <body>
  5. Validate with Google's Rich Results Test

Valid structured data makes a page eligible for supported search features, but Google does not guarantee that a rich result will appear. FAQ rich results are generally limited to authoritative government and health sites, and sitelinks are generated automatically rather than unlocked by one markup file.
