q=why+white+labels+are+bad+seo
Actually as it turns out ^^ white label SEO is a SEO agency term LOL.
White labels are just duplicate content and many don't allow indexing or have rel=canonical meta tagging. Others are separate versions of the same content shared in common by 100's or even 1000's of affiliate sellers.
So, unless you are going to buy traffic or feed traffic to a cam white label -- you are going to be very disappointed with the results.
