Just like you can turn a profit on sharing your skills online, you can also do so using your knowledge. There are a variety of sites out there that will pay you to do research, answer questions, or be an on-call expert in a number of different industries. Have a nursing degree? You can pick up some extra cash when you’re off duty by answering medically-related questions. Off-duty handyman or plumber? You can do the same thing with home improvement questions. If you just enjoy researching, you can pull in some cash by doing research through a website like Wonder.
Offering specific online SEO services is also another online freelancer role that businesses are crying out for. If you know how to improve a website’s SEO by doing keyword research, creating content that can rank in search engines, adding metadata/schema to posts and pages, and building backlinks to a domain, to name a few tasks, then this could be a great line of work for you.
