I've been using adsense in google in my blog site however I still have a few earnings on the number of impressions. I have placed several adsense from right to down just to have more space on advertisement as being mentioned on some forums just to have more impressions that you'll get. And its been a month now that the earning doesn't change or doesn't increase my earnings. If you could take a long on a blog site kindly have some suggestions and recommendations on how to increase my number of clicks and impressions. Please see the blog site on my profile. How do you increase your number of clicks?
