Low Infolinks Earnings……and Ad Layout option

I am getting relatively low infolinks earnings than I used to.
Few days ago I used to get abt $2 per day with about 2000 page impressions but now I get even less than $0.50 with same or higher impressions.
Please help…
Also I want to know that which layout of ads should be preferred on infolinks; The default one with green links and double underlned or making it blend with other links like single underlined and blue in colour. Which has high potential of generating more Click???
Please help??????????
