Adlift data from small-budget accounts. Short version: Google captures demand, Meta manufactures it. Under 10k MRR you usually have no demand to capture, so everyone runs Meta, burns cash, and concludes "ads do not work". The conclusion is wrong, the sequence is wrong.
Order that works: first, 500 euros on branded + competitor search (cheap, converts, funds the learning). Second, one Meta creative test: 3 angles, 2 formats, 20 euros a day each, kill fast (kill at 2x target CAC with zero conversions, no sentimentality). Third, only scale the winner, and only with fresh creative weekly (fatigue is real at small audiences, frequency lies).
Biggest waste: agencies selling 2k retainers to 3k-MRR products. At that size the founder must run ads personally for one quarter. Nobody will learn your customer for 2k a month.
