Hi, I have been having a disagreement with another online marketing company. We are both promoting the same product under a different brand name but we ended up using the same theme to build our WordPress sites off of but in no way is the content the same.
They are telling me that using the same theme in the same industry will cause a Google penalty. I do not believe this and do not see this causing a problem. The sites are relatively new so there is no proof of traffic dropping or penalties as of yet.
What is everyone's professional opinion on this? Can a WordPress theme cause duplicate content penalty? If so would that not mean that anyone using themes will have some sort of penalty?
