I am having few sites which I start for earnings from adsense.But now I understand one thing. Its of no use. I am getting only few pennies with even 1k traffic.
Then try something else. Or change the adsense so that it blends with the site: smae color background etc...
Patience is key.. keep building up the traffic for your site. Clearly the more people that visit the more chances of clicks. Best of luck.
Whats the niche? Maybe the site is not designed/written to convert? Is that 1k daily? Whats the target? 15-20 years old? 20-35 years old?
Just consider about your keyword of the website/page. Maybe you will be choose the high paying KW for your site.
