You can also put pages up on mirror sites (Smackjeeves, Comic Fury, etc). This will help get the name out there, but don't put too many pages since you want to be able to tell people "hey, to read the rest of the story, come to my official website of here..." And then link them.
Being active in communities is also very important. The good thing about webcomics is that readers can easily interact with the creators, and a lot of the times that makes them appreciate the work way more.
