Google is mixing up all the keywords and posts. I have a post targeting the keyword "discount XXXX" (POST A) and a post for "Cheap XXXX" (POST B) When I try to search discount XXXX, google returns POST B on the 7th page and it returns POST B on 7 / 8 th page when I search Cheap XXXX. I have compare the two post for things like keyword density and these two posts are not duplicate. This is only one example. A lot of posts are like that!!! Does anyone also have such experiences???
