Check backlink profile: If you’re not familiar with what backlinks are, they’re basically any public website that “links” to the domain in question. Since there are numerous shady tactics in the SEO world, expired domains’ backlink profiles should be examined carefully. Check if too many links are coming from the same domain or if links have weird anchor texts/use foreign languages. You can use a tool such as ahrefs for these purposes.
I've fixed some speed related problems and the new search cluster is now live. The combination of both speeds up every search noticeably. Also some unfinished expired lists are no longer in the domain name search. Some users noticed that you could already find TLDs in the domain name search that were not released yet. This is not possible anymore, however if you are one of those users, contact me. Let me know what TLD you are interested in and I will prioritize it.
Keyword relevancy is not the only thing that matters when it comes to SEO. However, domain names that were previously used by other businesses usually have a lot of backlinks and a decent ranking on PageRank. Even though such domain names are usually about to expire, they are still worth a lot of money if they have a good number of backlinks and a ranking of five or more.
