I have only one blog in blogger. These days normally i receive more-than 250 daily unique visitors and more-than 500 page preview (according to Google Analytics statistics). But my Google Adsense earning not exceed 3$ (maximum). Most of days i receive 2.5$ click 10. Yesterday 1.98$. So why is this. Majority visits come form USA, UK and India; and also70% of visitors come form Google search. I use 3 Adsense unites. One is below the post title (left hand side) another one end of the post (before the comments) and final ad unite in right hand side. So please tell me what's the wrong? I'm very very upset for this one!
$3 per 250 visits is good ratio, you should write more content and get more traffic. you may host a domain if you want more seo option.
Work on your ad placement. Use the google heatmap as a Guide, and move the ads into the hot positions. Left Sidebar, Above and Below the content are good.
500 impression, 10 clicks and $2.5, mean you are getting 2% CTR and $0.25 CPC which is considered as average (better than many publisher). You cant expect to make hundreds with only 500impression per day
If it just so easy to earn on adsense, maybe we should try it.. but basically it involves money, that's why it is slow.. it is not easy to get
But my traffic increase 50% but earning not increase. However 2 months ago my total daily visitors less than 130 and page preview less than 220 (according to Google Aanlytics) at that time my earning also 2.5$. So now my visitors double but my earning not increase its same as previous.
I have exactly the same problem, there is not matter how many visitors a day my website has the earning is not increasing, I have a flash game website, I earn exactly the sam when I have about 100 unique visitors a day and when I have a 500 unique visitors a day, that looks very strange , it seems like google change price per click if someone getting better traffic to reduce the earnings, that`s it what I observed on my example. This looks very strange, couple of first clicks gives me about 5-10 cents per click but at the end of day when I count that I get about 0,001 cent per click. I spent a lot of money to gain traffic from google but that has any influence on my earnings from adsense, no mater how many traffic I get I earn exactly the same money. So i think the AdSense is not worth of my time and I should pay more attention to CPA networks.
Try to optimize your content header and includes long tail keyword with some sense of curiosity to attract more targeted visitors to read it. Also, do not forget to replace your current keyword with the latest search trends you can find using the KW researching tool.
