Amazon affiliate: SEO Help Needed

This is the pickle i'm in.

I have a keyword lets call it "hat world" which has about 2000 monthly searches

However "pink hat world", "green hat world" etc all have about 700 monthly searches.

Would I have to make separate reviews of each combination on my amazon site? My fear is I will end up repeating many things which may affect me SEO.

But I still want to rank for all combinations

All your help and past experiences will be much appreciated. Thanks

create one post that includes all of those keywords, otherwise you'll end up with multiple web pages all focused on the same thing with the only difference being the "color word." One day Google may slap your site saying it has "thin or duplicate content." that happened to me :*(

I would target all three keywords on one page. That way my anchor text is diversified, after ranking for "hat world" you should see your other two keywords rise up in the search engine results. Then you can target the remaining two with exact match anchors and others.
