Technical SEO Audit Tool & Website Crawler

What is Technical SEO Crawler?

The Visiblio Technical SEO Crawler visits your pages the way a search engine does and reports problems that hold back crawling, indexing and rankings: broken links and redirects, missing or duplicate titles and descriptions, heading problems, canonical and noindex mistakes, slow pages, weak structured data and more.

Every finding says what it is, why it matters, which pages have it and what to do next, so you can hand the list straight to a developer or a writer.

Why use Technical SEO Crawler

One page or the whole site

Check a single address in seconds, or crawl a full website with the settings you choose.

Plain-language fixes

Each issue explains why it matters and how to fix it, not just a code.

Choose how it crawls

Pick the user agent, follow your robots.txt rules, include subdomains, ignore tracking parameters and limit depth.

Weekly monitoring

Save a website and get an automatic weekly check with alerts when something changes.

Traffic beside the issues

Connect Search Console and Analytics to see which problem pages actually get visits.

Frequently asked questions about Technical SEO Crawler

What is a technical SEO audit?

A technical SEO audit checks the parts of a website that affect how search engines crawl, understand and index it: status codes, redirects, canonicals, robots rules, page speed, headings, structured data and links. The goal is a list of fixes that remove obstacles to ranking.

How many pages can the crawler check?

You can audit a single page, or crawl a whole website up to the limit of your plan. The crawler follows your internal links and sitemap and respects the robots rules you choose.

Does it work on websites that need JavaScript to show content?

The crawler reads the HTML your server sends. For pages that build their content in the browser, Visiblio can also check a sample of pages in a real browser and flag differences, so you know when important content depends on JavaScript.

Can I check my site every week automatically?

Yes. Save a website in weekly monitoring and Visiblio runs the check for you each week and shows what is new, fixed or worse compared with the last run.

Is the Technical SEO Crawler free?

You can start for free. Plans set how many pages and runs you get each month, and you can see them on the plans page.
