Google reccomended only 20 keywords --- however I put 75 keywords ---- isn't more keywords better? Thanks!!!!!!!!
More keywords it's better, but you have to build your ad groups around the similar keywords. Many experts recommend max 20 keywords per ad group since there should be only related keywords. Do you sure that 75 keywords you're using, are tightly connected?
it is hard to have 75 highly relevant keywords targeted to 1 ad copy. My guess is your probably irrelevant if you are doing this like this. Also, 20 is not a magical number, its just an average. Some adgroups might have 10 while others have 30. But Google knows if your sticking 100 keywords in 1 adgroup, most likely they are not all relevant to the text ad.
