PPC
Pay per click. A model where you pay each time someone opens your ad, whether or not they buy.
Why it matters when you read an offer
It matters because with this service you pay twice: once for the work, and once for the clicks themselves, to Google or Meta. An offer where the two amounts are not separated cannot be evaluated.
What it looks like in an offer
Ad management with one blended amount. Ask what part is the work fee and what goes to the platforms as budget: those are two different numbers.
