I have a problem with one of my sites. My site is about cars and I have as anchor texts: Volkswagen Cars opel cars mercedes cars audi cars ferrari cars The problem is that was positioned on page 4 for keyword "cars", but now I am not in the top 10. I've never done any backlink to this keyword, only for the other anchor texts. Anyone know if this is a penalty? When using other anchor texts are considered too I am using the anchor text "cars"?? Hopefully some advice.
