The Screaming Frog SEO Spider is a small desktop program you can install locally on your PC, Mac or Linux machine which spiders websites’ links, images, CSS, script and apps from an SEO perspective. The Screaming Frog SEO Spider fetches key onsite elements for SEO, presents them in tabs by type and allows you to filter for common SEO issues, or slice and dice the data how you see fit by exporting into Excel. You can view, analyse and filter the crawl data as it’s gathered and updated continuously in the program’s user interface.
The Screaming Frog SEO Spider allows you to quickly crawl, analyse and audit a site from an onsite SEO perspective. It’s particularly good for analysing medium to large sites, 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.
The Screaming Frog SEO Spider allows you to export key onsite SEO elements (url, page title, meta description, headings etc) to Excel so it can easily be used as a base to make SEO recommendations from. The video below provides a demonstration of what the SEO tool can do:
