With the help of Vitamin.Tools, I was able to create my own small marketing agency. This service allows me to optimize workflows and manage all clients from one account. In principle, it's possible to operate without employees to promote companies in different niches simultaneously. If any difficulties arise, I can always reach out to the managers for assistance. Moreover, all the funds I receive back from the affiliate program, I don't withdraw but invest in advertising for my agency. This way, I am currently promoting myself completely for free.
