Googles John Mueller said when it pertains to repurposing old domains that may have not been utilized but were being redirected elsewhere, it is great for the many part. The only cases where it can trigger SEO or Google ranking problems is if that domain was redirected or used in pure spam cases or for adult sites.John was asked “should I be concerned if I buy a domain that has been rerouting (or has zero traffic) in the last 17 years?” John reacted “Its probably fine, assuming its been redirecting to a sensible destination.” The rerouted area really just matters if it is was rerouted to pure spam or an adult site, John included later on. “I d just inspect where it goes – its normally easy to inform if its pure spam or an adult site,” John stated. John added “anything else is probably okay.”Here are those tweets: Its most likely great, presuming its been rerouting to an affordable destination.– & #x 1f9c0; John & #x 1f9c0; (@JohnMu) November 28, 2021 I d simply inspect where it goes – its typically simple to tell if its pure spam or an adult site.

The pure spam is somewhat new to me, like a domain can have such a bad history of spamming that Google will not be able to handle brand-new material and brand-new purposed on that domain even if the domain has not been used for some time.Forum discussion at Twitter.
