Congratulations Lazer317 on earning your first cent. Many big journeys begin with a small step.
1. Keep motivation high. The initial weeks/months are going to be slow - both for traffic and money. Make sure you have other sources of revenue to sustain yourself during this time.
2. Write more. Write better. Write faster.
3. Keywords. Choose 10 or 20 keywords. And write content around ONLY those keywords for the whole year. Yes, one whole year. Use Google Keyword Tool to choose those 20 keywords. Ideally the keywords should be related. But that's not absolutely necessary.
4. Write on other websites (on sites suggested by other hubbers here), and create backlinks from those sites to your hub(s). Make sure the backlinks are created using your kewords as anchor texts. Don't insert more than two links in one external article.
