I have been working as a freelance writer for a long time. Don’t worry about freelancing it always takes time to be credible enough to get more work, but you can start trying by posting ads about your services on several platforms. If someone searches for how to create a Wikipedia article about a person, the search engine will show the ad or link to your profile. By posting ads on different platforms will be more beneficial than you expected. So, I suggest promoting yourself on different platforms online to make sure you are selling your service correctly.
