Do I need a website?

Right now I'm not getting a lot of views, but I think if I had a website I might get a few more. I don't really know how to build a website, but I'm sure if I found the right book I could. I read that having a website makes it easier for search engines to notice you. I'm not sure if the search engines are picking me up now, but I think it would be nice to have a bigger audience. I just don't know if having a website is better than having social media.
