Stable income: Stable

A digital marketing agency can offer a stable income source for those who have the skills and dedication to build and maintain a client base. From personal experience and online research, many individuals consistently earn from this side hustle. While there can be fluctuations due to market changes or client acquisition, overall, it provides a reliable source of income for most. I'd rate it a 4 out of 5 because it offers decent predictability with stable monthly earnings for those who put in the effort.
