I have two separate Asins, they are not same parent child, but they are quite similar products. My question is If I target the same keywords for them in manual campaigns, would they compete with each other and eventually prevent one of them not getting impressions? That is can I target the same keywords for this two separate Asin?
Yes, they partecipate both in the auction. Anyway, I’ve read from the Advigator blog, it’s better to keep one campaign per Product (Parent-ASIN + variations) to have better visibility in the advertising report.
