Why give these away for free? These tools solve the practical, recurring tasks that happen every day in SEO: checking a robots.txt file, validating a sitemap, or generating schema markup. Rather than solving them privately every time, I built them as tools anyone can use. They show the kind of technical work behind the paid services, without pretending a tool is a substitute for strategy.

What These Tools Are Great For, and Where They Stop

A free tool can tell you that a page is missing a tag or that a sitemap has a broken URL. It can't tell you which of the 200 issues on your site actually matter. Knowing when to use a tool versus when to get help is critical.

These tools are a great fit if:

  • You need a quick, one-off check or file generated, a single page's on-page elements, one robots.txt file, one sitemap.

  • You're a student or course learner practicing hands-on SEO skills and want to check your own work.

  • You're a developer implementing a specific SEO recommendation (schema, redirects, sitemaps) and need a fast, no-login utility.

  • You want to spot-check something before deciding whether it's worth deeper investigation.

You need more than a free tool if:

Getting the Most Out of These Tools

These tools give you data or output (a list of issues, a generated file, a validation result), but interpreting that output and deciding what actually matters is a separate skill entirely.

Treat a tool's output as a starting point for investigation, not a finished verdict. A page that passes every technical check can still fail to rank if the content doesn't match search intent. If you want to build the judgment to prioritize what these tools flag, I recommend starting with the SEO Course: Basic to Advanced or, if you already practise SEO, the Advanced SEO Course.

Being Honest About the Limits

  • These tools check one page, one file, one specific item, or a sample of up to 100 pages at a time; they don't run ongoing, automated monitoring across an entire site.
  • They surface issues and generate output; they don't prioritize which issues matter most for your specific business or judge trade-offs.
  • They don't replace a full technical, content, or migration audit for complex or large-scale sites.
  • They don't provide strategic recommendations, only the specific check or file each tool is built to output.

Need Help Beyond the Tools?

If you've run the checks and realized you need someone to interpret the results, prioritize the fixes, or just handle the execution for you, the next step is a strategic service or a structured course.

Frequently Asked Questions

Yes. Every tool listed on this page is free to use for checking individual pages or generating specific files.
No. You can use these utilities immediately without creating an account or logging in.
The tools provide accurate technical readouts and properly formatted file generation based on standard SEO practices, but interpreting whether an issue actually matters for your business requires human judgment.
No. These are single-file, single-page, or specific-task utilities. They do not crawl or monitor your entire website on an ongoing basis.
Use the On-Page SEO Checker to review a page's title tag, meta description, heading structure, and core content elements.
The Generator writes the JSON-LD code for you based on the information you input. The Validator checks code that already exists on your page to see if it has errors.
The Redirect Rule Generator writes the actual server code (like .htaccess rules) for a redirect. The Redirect Mapping Tool helps you organize and match old URLs to new URLs in a spreadsheet format before you implement them.
The Redirect Checker traces one URL (or up to ten) hop by hop and shows every status code, header and timing, including the http, https and www versions. The SEO Migration Redirect Checker takes a long list of old URLs, usually with the new URL each should reach, and checks hundreds of them at once against your redirect map.
The Core Web Vitals Checker shows what real Chrome users experience (LCP, INP and CLS) plus a Lighthouse lab test, using Google PageSpeed Insights. The Website Performance Checker does not use Google: it measures the server response, page weight, render-blocking files, images, caching and compression directly, and explains the causes. Use the first to see whether there is a problem and the second to find what to fix.
The Keyword Generator creates new keyword ideas from a seed, using real search autocomplete. The Keyword Extractor reads a page or text and shows which keywords it already uses and where. The Keyword Density Analyzer measures how often specific target keywords appear and whether they are over-used. Generate ideas first, extract what competitors use, then check your own page.
The Website Health Check is the wide scan: it samples speed, security, crawlability and on-page basics and tells you what to fix first. The Security Headers Checker, SSL Certificate Checker and HTTP Header Viewer go deep on one layer each. Headers are graded and come with copy-paste config, the certificate is checked for expiry, names and issuer, and the Header Viewer shows the raw response at every redirect hop. Start with the health check, then open the one it points to.
No. The tools are designed to handle the technical formatting for you (like generating XML or JSON-LD), but you will need to know how to upload or add the resulting code to your website.
Yes. The generators create the required format automatically from your inputs, making it simple to create or convert sitemap files.
No. The tools surface issues and generate output, but prioritizing what to fix requires understanding your specific business goals and search strategy.
No. These tools are useful for spot-checking individual pages or tasks. They do not replace the comprehensive, site-wide diagnosis and prioritization of a professional SEO audit.
The Mapping Tool helps you plan where URLs should go before a migration. The Redirect Checker tests them after the migration to confirm they actually resolve correctly.
Yes. The toolkit evolves based on the recurring problems we see in active SEO and consulting engagements.
Yes. You can use the Contact page to suggest utilities that would be helpful for your daily SEO workflow.
