Low search volume KW & QS issues
I have a group with many Low search volume KW, why don't they show up even when the search exists?
On th other hand i have 3 KW with QS of 1/10, two of them are showing and the third one isn't. Why is this? is it because of IS percentage?
Re: Low search volume KW & QS issues
There is a lower threshold of ad rank specific to KWs below which Google will not bother to show the advert. (That's because - based on former stats - the algo thinks users will not click and they will not accrue revenue.) The formula for Ad Rank is this: QS * Bid.
3 KWs with QS=1/10. Same reason for not showing. The reason for the ones that showed might be that the algos occasionally perform tests to see if users' clicking habits are changing.
