Well after a relatively successful first couple of months (no great hiccups!) I am in the proccess of concentrating my ads from what I have learnt and oh boy the more I think about it, the more mass of work is involved.
I have read that others think there should be no more than 6 words in each adgroup, I disagree with this and think there should be no more than 4, maybe even three in some cases! (I noticed a BIG difference in CTR whenever keywords were in title of ad)
With negative words included + all the connotations that can derive from even 3 keyword listing (including mispells) is making my campaign screen too long to pragmatically manage, so that leads me onto another recent post I made about when to categorise ads into seperate campaigns, even when they are closely related...still an ongoing issue.
But I digress, back to original point...I am beginning to get concerned that I am thinking too hard about this and wasting efforts concentrating the adgroups.
So has anyone got an opinion/experience when you past the threshhold of worthwhile efforts? Or is this never reached?
