Today, Adsense announced about two recent changes to their site targeting feature, Say hello to placement targeting.
What is site targeting feature? Site targeting allows advertisers to select specific publisher sites on which to run their ads.
Advertisers can target your site if they have determined a match between their offerings and the interests of visitors to your site.
The first change is that they have renamed ‘site targeting’ to ‘placement targeting’ to better reflect the variety of targeting options they offer.
Advertisers can still target their ads to an entire site, but they can now also target your individual ad units or groups of pages based on how you have set up ad placements using custom channels.
The second change is that advertisers can bid on placement-targeted ads (formerly known as site-targeted ads) on a cost-per-click (CPC) basis.
Previously, advertisers could only bid on these targeted ads on a cost-per-impression (CPM) basis. Just as with contextually targeted CPC ads, you willl generate earnings for valid clicks on placement-targeted CPC ads.
Here are some tips to maximize your revenue potential with placement targeting:

Google Adsense launched a new feature, Simplified ad management. They promised about this feature two weeks ago, Coming soon: Make ad changes without replacing code.
Simplified ad management will save the settings of your ad units within your AdSense account. That means, each time you want to change the colors, channels, or even the corner styles for your ad units, you can make the changes directly in your account rather than generating and pasting new code.
Google Adsense were still working on rolling this feature out to all publishers, so don”t worry if you don”t see it in your account yet — it”ll be there soon. Fortunately, I see this feature in my account. Great!

This feature made your adsense code different from your current one.
Adsense Old Code

Adsense New Code

Hopefully, this feature will save the settings of my ad units within my AdSense account. Have a great day!
