Until we forgot we had the old site, the domain name expires and we realise it only 1 month after it is gone. A huge dip in our SEO visibility and traffic starts to disappear.
We repurchased the domain, by luck we had a full backup of all pages before the expiry date and put them all back up and decided to relaunch the 301 redirect to save/ restore any link value we may get.
Till this day we haven’t seen improvement and we are looking at a massive loss of opportunity
