If I set up a campaign with 2 adgroups like this: adgroup 1: keywords: kw1 kw2 kw3 adgroup 2: keywords: kw4 kw5 kw1 Both adgroups use the exact same ad. Is there any disadvantage to doing this? I am copying / pasting some keywords and some are ending up in multiple campaigns. Would it be smart to delete the duplicates (which would take a lot of time), or does it not matter? Thanks, Matt
By having the same keywords across different ad groups only one of them will show up, usually the best performing keyword of the bunch. I would recommend removing the duplicates as it makes analysing the data that much harder when you have the same keyword across a number of ad groups.
