Should I add negative keywords to main ad group
Re: Should I add negative keywords to main ad group
Hi David F,
If your main keyword "red widget" in Exact match then you need not to add "bright red widget" & "small red widget" as a negative keywords.But if you are main keyword "red widget" is in Phrase,Broad or BMM then you can add those keywods in negative list with exact match.
When multiple keywords within the same adgroup or multiple keywords within the multiple adgroup matches the search terms then Google takes some complex decision in order to show the most relevant ads.
