I am trying to help a client just boost their rankings and organic reach, but for the longest time they will just copy and paste like a top ten list from a page and use it in a blog post. Should I go back through and just delete the copied lists, will that be enough? What kind of damage would this have done in the eyes of google? It is a pretty competitve niche. Thanks for any advice I am still a little new at this. Is the damage done and should I just leave it and go after social instead?
