We have a new client that previously used a company that really messed up their on page seo as well as many other things. The main site, example.com had two other sites called example1.com and example2.com. Apparently the original strategy was to create content on the 1 & 2 domains and point them both to example.com. They also had the main site link to the two other sites. Most of the content was identical and they got smacked hard by Google a while ago.
My main question is this, should we just completely remove websites 1 & 2 with no trace? Or should we point example1.com and example2.com to example.com? Or perhaps something else?
