The best way to find freelance marketers is to use a freelance marketing website. These are recruitment sites that hold databases of freelance digital marketers available for hire. Some specialize in digital marketing professionals only. Others have listings for all types of freelancers, marketing included.
Most freelance marketing sites let you search their talent pool for suitable people. Many also let you post job opportunities. And then match you to candidates. You usually pay rates set by the freelancer. Some sites offer fixed-price packages for defined jobs. Most sites also help you manage projects, performance and payments securely.
The best sites to hire digital marketing freelancers are Mayple, Contently, MarketerHire, Fiverr, and Upwork.
