Before being accepted into a project, the local organizations will look at your profile to see if they want to talk to you. The more information you include, the better. These factors will also help you rank higher in the search.
Additionally, displaying your social media profiles helps prospective organizations get to know you a little better before agreeing to speak with you. It helps them understand if you’re a good fit for their needs. This is optional and you can opt-out of it if you wish.
