Buy Expired Old domain without losing Age

I am interested in buying a few expired domains, but do not want to see those as a few days old after my purchase in tools like https://websiteseochecker.com/. What are the options to regain or retain the age property even if it has expired? Should I contact https://websiteseochecker.com/ or?

If it has expired, you cannot regain the domain age. The only way is to buy an auctioned domain, where age is preserved.

There are a few scenarios to consider:

1. As mentioned above, the best-case scenario is buying the domain at auction—this way, the domain’s “history” is preserved.
2. If you’re registering a domain that’s currently available (i.e., at base registration cost), it’s best to choose one that still has pages indexed in Google or Bing. You can check this with a site:domain.com query.
3. And finally, the least favorable case: when the domain has no indexed pages left. This is more of a gray area filled with myths and speculation. But ideally, the last archived snapshot with actual content in the Wayback Machine should be no older than one year.

You can try to contact https://websiteseochecker.com/ and ask them if they can help you retain the age property of the expired domains you are interested in buying. They may have some options or advice for you on how to maintain the age property even after your purchase. It's worth reaching out to them to see if they can assist you in this matter.
