Just write a plugin that gets the content, splits it in half (more or less depending on your rules), adds the ads and puts it back together again. I've done it on mine and while it was fiddly to get the balance right it works well enough.
display adsense ads right below the title or anywhere on the top of the page. This will surely increase your CTR & eCPM.
See if you are getting good traffic and having less earnings than its time to make changes in ads such as adding more ads and doing more experiments by this you can increase your earning in adsense and also you will learn what works best....
I would advise you to keep targeting new keywords related to your niche and make a quality resource in which people naturally link to.
game niche is very low paying..it's very hard to get $1 for a single click..you can blend the color with your site and you can use many image ads to attract more visitors
To earn some thing you have to spend little and earn much hire a SEO i agree with above poster seo is the best solution.
get an automated system that already has website built and has adsense on it you just need to put your adsense id and you'll earn like crazy. the only thing you need to do is get traffic and watch your money fly in there are lot of systems to choose from but they're all nice check out the ones you like on my site atajan.com
Be sure to use channels to track which ads work best (text vs image), size and placement. I've tweaked my site quite a lot to earn about $50 to $75 per 1,000 unique visitors from Google ads alone. I have many pages like this one (list of Las Vegas hotels) that have a high click through.
That's a good idea. I'm actually only using the channels to track the performance of different sites right now. But one can do the same with different ads as well to check them out.
you need to do email marketing of your site or do SEO of your site it take many user to your site the greater the visitor you have the great chance you earn more from it.Also use social network site for your site marketing.
