All paid search specialists should subscribe to the A.B.T. Rule, meaning we should Always Be Testing. We should always be testing new keywords, keyword bids, ad copy, average position, ad extensions and everything else in our accounts! If we subscribe to this rule doesn’t it make sense that our paid search providers should be doing the same? Well if you are seeing these new green ad labels in your SERP results you are seeing a Google paid search test in action.
