Is it wise to run both Automatic and manual campaign at the same time?

Hi Angell,

The short answer - absolutely!

One practice I follow is that I use automatic campaigns to harvest keywords for a product.
Once I find good keywords that convert, I will then move them to a manual campaign and add them as negative keywords to my automatic.

One advantage auto campaigns also have is that they are advertised on other products - this is why you may see an ASIN as a search term on the search term reports.

A disadvantage is that Amazon is choosing the keywords so you may have some irrelevant search terms that are costing a bomb - again an easy fix is the add these to the negative terms as soon as possible.

Have fun with it!
