I am so glad I find this thread. I am new here, but I am beginning my way into a Bingo site as well. As a newbie my strategy is focus on the content, even though it is hard to compete with generic terms, you can go a deeper and find some opportunities.
@fonzi: can you tell us a little bit more about your experience? How many hours you dedicate to your site? When you expect to see some results?
Thank you for sharing and have a nice day.
