It's pre-set for SEO
Crawling an entire site is generally unnecessary and takes a long time. I like that SEO Radar sends emails on all the SEO elements someone typically cares about. It's pre-set for SEO. They already know what people are looking for, and it's helpful that they spoon feed you: on this day, this element on the page has changed, and this is what it used to look like. They already capture the screenshot for you.
