I like using Ahref's Content Explorer tool to find similar content/backlinks etc. But I think if they simply showed broken links as well for topics/keywords, that would be so useful in building links.
Does something like this exist? It was suggested as a feature over a year ago but it hasn't gotten anywhere: https://ahrefs.canny.io/content-explorer/p/add-broken-yesno-filter
It looks Aherfs' API has the functionality to separate broken links: https://ahrefs.com/api/documentation/broken-links. We just need to search by anchor text, title and alt text.
