I am getting around 300 unique visitors per day and over 700 PV. Yet my earnings are meager and hover around 4 or 5 bucks per day. There is only one ad unit that is placed just under the title of the article. I tried various positions for ads but only the ads that are placed under the title are getting some clicks. If you have time, check the link in my sig to take a look at the position. I am looking for tips on increasing my adsense revenue because I feel that I have decent traffic.
That's already a very good CPM rate (about $5 or so, right?). I would be glad to get that much revenue with that less traffic. Change the green color to a color that is more related to your site. Put a block in the top of the context navigation. Use AdSense in your Youtube videos (as a partner if you are not the uploader itself). But why you just want to get more using AdSense? There are a lot of other networks with other advertising methods. Something like Adf.ly's 'Full Page Script' for outgoing links. Not much confusing layer ads like Clicksor's bottom layer banner. Just for giving you an idea of alternate networks. But once again: Your CPM is already very good. Try to get more targeted visitors to your site.
Its good but you can increase by putting one image ad on sidebar. You can even put one image/text ad at the end of post.
I think that kind of traffic, it's already good enough earnings. You should be focusing on driving more traffic to the site. Of course you can still tweak it but I doubt it will make a big different. Is that the site that you're talking about (at your signature)?
