FAQ
What is the best tool here for smaller accounts?
A tool that ranks by baseline outperformance (like Posteriks) beats raw-number tools, because big numbers favour already-large accounts.
Do I need more than one?
Often one viral-insight tool plus one for production or scheduling. Buying by job beats buying an all-in-one that is average at each.
