How to Choose an App Marketing Agency in New York
- Check the New York claim. Clutch's New York list includes agencies that only "serve" New York from other cities.
- Ask what they report. Ask for cost per trial, subscriber or paying user, not only cost per install.
- Read the low reviews, not only the average. A 4.5 can hide a run of 1.0 scores.
- Check who owns the ad accounts. If the agency owns them, your history leaves with the agency.
- Separate agencies from platforms. A programmatic platform sells inventory; an agency decides where to spend.
