You've answered your own question.
You are on page 3 and getting about 10 a day = 300 a month, that sounds better than average as not very many people actually make it to the third page, unless you are providing something very unique and specialised, and folk need to sift through pages.
Your question should probably be more geared around "What optimization do I need to do to try to get my site to rank higher".
Oh you have no idea how much work I put to make it to page 3...
Let me rephrase my question.
At what rank shall I see decent traffic for the keyword that I'm targeting?
Sorry if I sound a bit rude but making money off SEO is much harder than I thought...
i m on the top 4 with a EMD which has 3k monthly exact visitor but getting only 4/5 visitor daily.When you hit top 5 you will start to see real traffic.
