I bought a few expired domains, the 1st one I can actually use had a 301 redirect to a spammy site for years but managed to keep a Moz page score of 45 and domain score of 38. I was wondering how to best utilize this one? Should I scrape the old site page from wayback and use WP to make it sort of like that and then just put a blurb on the site linking it to my money site ? The site I bought has to do with dogs, my site is about travelling so I was going to link it with the text "travelling with dogs" or something like that. Or should I just 301 redirect ? The other sites I bought were travel sites and never had 301's or spam links etc how should I use those ? Thanks just getting my feet wet again after being away from SEO for years.
