When looking for broken links, the content explorer is potentially a great tool as I can enter a keyword, such as 'healthy grains' and see 700 articles relating to it. If this report showed which of these 700 articles were broken/dead, then I'd very quickly have a list of articles that I can replicate and then outreach the backlinkers.

Generally using various tools across the web, I've found looking for broken links from a keyword very difficult and time consuming. Your report has the potential to automate this process completely.
