Nevermind how many people actually SEARCH for a given term in a month. Let's say that only a limited amount of advertisers buy that term, and that they can only afford a low amount of click-throughs per day. That might result in, say, only 1000 click-throughs per day between them all.
It might only take 200,000 impressions before all 1,000 click-throughs were "used up", but Google might have 800,000 impressions to offer between themselves and all their publishers.
If that was the case,Google would "run out" of click-throughs every day.
So instead of running PSA's in the extra 500,000 impressions ad space, they decide to do a number of things:
a) substitute other, high-paying ads, which is better for them and for us versus running PSA's
b) split the impressions out throughout a 24 hour period, so all the click-throughs don't "run out" at 2am
c) and/or rotate the impressions around a series of different sites throughout the month, so everyone has an equal chance of getting a portion of the 1,000 per day click-through revenue?
d) some or all of the above, testing out which is best for everyone
If this is the case, it adds a new wrinkle to our work as publishers: trying to find search terms that don't have too much available inventory.
I don't know. I'm new to all this. Is this too obvious?
b) split the impressions out throughout a 24 hour period, so all the click-throughs don't "run out" at 2am
I think this has been a standard feature for Adwords/Adsense since the beginning.
But advertizers can also run or pause their ads pretty much at will as I understand it. So ads that are available at prime time may not be available in the middle of the night for instance.
