From uncovering serious technical SEO problems to crawling top landing pages after a migration to uncovering JavaScript rendering problems to troubleshooting international SEO issues, Screaming Frog has become an invaluable resource in my SEO arsenal.

" Screaming Frog Web Crawler is one of the essential tools I turn to when performing a site audit. It saves time when I want to analyze the structure of a site, or put together a content inventory for a site, where I can capture how effective a site might be towards meeting the informational or situation needs of the audience of that site. I usually buy a new edition of Screaming Frog on my birthday every year, and it is one of the best birthday presents I could get myself. "

About The Tool

The Screaming Frog SEO Spider allows you to quickly crawl, analyse and audit a sites’ onsite SEO. It can be used to crawl both small and very large websites, where manually checking every page would be extremely labour intensive (or impossible!) and where you can easily miss a redirect, meta refresh or duplicate page issue. You can view, analyse and filter the crawl data as it’s gathered and updated continuously in the program’s user interface.

The SEO Spider allows you to export key onsite SEO elements (URL, page title, meta description, headings etc) to a spread sheet, so it can easily be used as a base for SEO recommendations. Check our out demo video above.

 

Crawl 500 URLs For Free

The ‘lite’ version of the tool is free to download and use. However, this version is restricted to crawling up to 500 URLs in a single crawl and it does not give you full access to the configuration, saving of crawls, or advanced features such as JavaScript rendering, custom extraction, Google Analytics integration and much more. You can crawl 500 URLs from the same website, or as many websites as you like, as many times as you like, though!

For just £149 per year you can purchase a licence, which removes the 500 URL crawl limit, allows you to save crawls, and opens up the spider’s configuration options and advanced features.

Alternatively hit the ‘buy a licence’ button in the SEO Spider to buy a licence after downloading and trialing the software.
