I just got adsense up on my website and i was just wondering, can i put a text unit and directly below it an ad unit? Is there any rules saying there has to be space in between them? Also yesterday i received one click and it was only 8 cents? is this the average at adsense? and what can i do to increase it? thankks
Yes is the answer to your first question. Some ads pay in dollars while others will get you as little as 1 cent. You can reduce the number of ads on your site to increase your CPC (earnings per click) but it will likely reduce your CTC (the number of clicks you get). The best option is to aim for a balance between your CPC and CTC. Apart from that you can aim to target high paying keywords.
