Screaming Frog Crawl

Example of a sitemap.xml crawl from Screaming Frog. 

Some Key points I look for from a Screaming Frog crawl of a sitemap.xml include: Missing Meta Content - Titles, Descriptions, and H1s. These represent key tie-ins to the page content and its context relative to the searcher's query.
I also look for self-referential rel="canonical" tags, over- and under-optimized meta content, and any retired, redirected, or non-indexable pages. this review gives a good high-level overview of the site's health and hygiene.
