There is a secondary registrar check built-in, so shouldn't happen very often, so that's the amount external domains we found. Then out of those how many of them are expired domains we've found which will appear in here or in any of the other ones, depending on which type of crawl were running, and that's just simply how long this crewel has been running. So we've got a lot of the similar settings here, in the search query crawl. We have how many queries have been blocked, which you shouldn't get many with any blocked because you're, not hammering google, you know you're sending one query and then processing the results and then sending another query see not scraping Google all all at once. So that's how many queries we've done and how many we've got left to process.
We do not only have Expired Domains, but you can also find lists of Deleted Domains for a lot of TLDs. Deleted Domains or Dropped Domains are available for registration and can be picked up for just the normal regfee at your preferred domain registrar! All Domains have the typical SEO relevant data, like Number of Backlinks, Archive.org Birth Date and a lot more.
