Hi
There's something not clear in the description of an auction model:
You determine the maximum amount you are willing to pay for a tap on your ad. Using a second price auction, Search Ads calculates the actual cost of a tap based on what your nearest competitor is willing to pay for a tap on their ad, up to your maximum cost-per-tap bid, so you’ll always pay a fair market price.
Ok, I define max CPT.
But what if there is no competitors for the keyword? For example I need to show my app for the people searching for the keyword "Several Species of Small Furry Animals Gathered Together in a Cave and Grooving with a Pict". There are no competitors. Can I pay $0.01 for the tap? Or $0.00001?
What if there are 1000 people searching for the keyword "furry animals" today and my competitors have budget for only 900 of them? Will I be able to buy 100 tap for $0.0001?
So basically the question is what max CPT should I set for extra rare keywords and what will be the actual (not max) CPT?
