I highly recommend Screaming Frog for any person involved in SEO.

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.
