Im working on a fairly new amazon affiliate niche website and the brand new domain wasn't brand new after all, its about 6 years old. After bringing up the history at archive.org, the site was also an amazon affiliate site and was targeting my exact product and niche. Webmaster tools is clear of any penalty messages and the site is indexed on the search engine. I ran the site through ahrefs and checked out the backlinks profile which only shows 2 random blog sites. However, majestic indicates 1500+ historical backlinks which kinda throws me off. I also ran the site through this penalty checker tool, it shows my sight maybe sandboxed or penalized. What do you guys recommend I do with this site of mine? Continue building it up or cut my losses and start a new domain? Thanks!
