How can I improve on my sites income? I know content is the main thing holding me back, any other ideas? template? ad locations?
What you need is a complex web site with hard links to related content. Rich with good well written information about the topic an also ads in various places. I have seen a fantastic format that brings in about $8k per month on a regular basis. But it takes time for it all to come together and be crawled deeply by the G bots.
