How to evaluate the services of an SMM specialist?

Question

SMM

Tell me, please, how to evaluate the services of an SMM operator? Is there hourly pay?

Answer 1

piecework - for posts, has
hourly - hardly
for likes - even muddier

Answer 2

Likes generally wind up simply, literally a few kopecks per like) Hourly is also muddy.
I would suggest making a KPI system and evaluate according to it. Roughly speaking - for each client who applied - 10% of the profit. Here it will immediately be seen whether there is a sense from the specialist or not.

Answer 3

By fulfilling the content plan (number and frequency of posts and their relevance to topics) and by conversion into clicks on links in them.
