These are actually some really good ideas!Some good answers there.
You can also open up a Facebook page and get a page and url vanity name the same as your website name if you can. When you post content on your website, you can put up a post on FB with an excerpt and call to action to get them to your site.
Obviously you're going to want some fans to your FB page. Get people you know to like your page. You can run a small ad campaign for page likes with a daily budget of $5 for maybe a week or so.
This ought to get you going.
