    There is research to indicate that running multiple ad versions may result in higher clicks and conversions over the entire audience than selecting just one “winner”. Some people respond to one type of ad; other people like a different type. By varying the ad types, you can sell to everybody. People often see the ads more than once before they click. Running a set of ads can give the advertiser a second (or third) chance to convert.

    Good addition. I used to write a bunch of differents ads per adgroup. Rotate envenly and then with good data, optimize for clicks. I will definitely have a go to that one.
