It can be used to crawl both small and large websites, where manually checking every page would be extremely labour intensive, and where you can easily miss a redirect, missing page title, or duplicate page issue. You can view, analyse and filter the crawl data as it’s gathered and updated in real-time in the apps UI. 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. Crawl 500 URLs For Free The ‘lite’ version of the tool is free to download and use. For just £199 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. Updates
