From Screaming Frog:
Screaming Frog SEO Spider is a small desktop program you can install on your Mac to spiders websites' links, images, CSS & scripts from an SEO perspective. You can view, analyse and filter the information as it's gathered and updated continuously in the program's user interface. The Screaming Frog SEO Spider allows you to quickly analyse or review 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 and where you can easily miss a redirect, meta refresh or duplicate page issue. The spider allows you to export key onsite SEO elements (url, page title, meta descriptions, headings) to Excel so it can easily be used as a base to make SEO recommendations from.
