I sometimes think we AppTheme members should have our own little club were we go around clicking on each others ads. Not too often, but maybe enough to help pay the bills! (Just joking Mr Moderator!).
Having said that, I may have clicked on some of your ads just now, but I wouldn't do it too often since Google are very smart!
My stats are not good, but its not because of AppThemes. It is a tough market in Australia. Gumtree has everything sown up. Trying to get people to place ads at my website is impossible.
And trying to get people to discover you is also difficult. Advertising cost money especially pay per click that Google and Facebook offer. We also have tough Anti-Spam laws so I can't exactly go sending unsolicited emails or text messages.
You've got a healthy number of ads on your website. at least people are using it, which is something.
