Have a situation here, which is new for me. My potential client has two ecommerce websites (1 old, 1 new), which for now sell THE SAME products. In future it's planned to add different categories to each website, but they will sell products from the same niche anyway.
So the questions are :
1) is it good or bad for overall SEO campaign, to run two similar websites? As I see it, it's more beneficial to put all the efforts in improving 1 website, than to disperse money and efforts…
