Hey guys - newbie looking for help understanding SEO. The question is would it be better to do one site or four. I started a blog a few weeks ago and I am starting to get a little traffic for a keyword I have targeted. I have found three other related keywords and I'm not sure of the best approach. For the sake of this conversation lets say my niche is pet food and I have found good key words for "dog food" "fish Food "horse food etc. Would I have a better chance for ranking if I do them all together on one site or should I create three additional sites. Thank for any help you can offer.
