Keyword targeting with irrelevant content - Against TOS

We could see many websites with content which are irrelevant to the ads displayed by Google Adsense for that particular site. It's not because Google adsense have done their job wrong, its again one of the game played by the webmaster for greater earnings. The webmaster could target ads to high paying keywords even though the ads which ought to be displayed are low paying. The publisher could produce some clicks to his ads even though the ads were not related to the content. This could produce more earnings than with the usual keywords he could have used relating to his content. His content would be liked by large number of visitors but could be of very low paying ads which could show up for that content. This tactics is now a greater problem which could produce unwanted clicks for the advertisers. This results in a failure in Google Adsense. So Adsense have started taking appropriate measures against such methods employed by some publishers. My friend was once warned and was asked to make appropriate changes to his site if he was interested in Google Adsense anymore.

Adsense warns Publsihers for adult contents.

Adsense warns publishers through email if they had adult related content. eg , if they had pictures and wallpaper collections with some adult touch in it. Its not necessary that the pictures were naked and or porny. Google Adsense considers photos with some adult touch in it as adult content. Adsense just gives an opportunity for the publishers by leaving them with just a warning rather than disabling their accounts. Adsense had just stopped serving ads to such sites.

Google Adsense makes landing page costlier for slower sites

Adsense now demands more CPC for a website for using adwords if their landing page of their sites are loading slowly. This shall increase the quality of the adwords users. If their pages are loading slowly, their CPC campaign would cost 5-10 times higher than the other competitors targeting for the same keywords. This act done by Adsense would lead to increase in the users using Adwords and would also result in happiness for the publishers for displaying Ads of adsense which would load fastly resulting in more people interested in clicking on Adsense ad units.

Google Adsense banning publishers for the goodness of both.

We could see that Google Adsense bans many publishers periodically. Many publishers would think that its just for the goodness of Adwords members. Even though its the main factor, Google Adsense does it also for the goodness of other Adsense publishers. We could see that many Adsense publishers facing drastic times of getting very low ecpm, its because of the publishers who does not comply with the TOS of Adsense.
But while disabling accounts for many publishers, Google Adsense have to consider the publishers who were innocent and their accounts could also have been banned. They should alteast respond to the request of the publisher regarding his account's reinstatement.

Adsense are now very strict regarding their payouts..

There are going to be lots of problems regarding the payouts for the disabled accounts. Usually Google Adsense ships their cheques at the end of the month, lets consider that to be on march 27th.
But if your account is getting closed on April 8th or 9th, then if you have received the cheque before that and if you had already encashed it before the account has been disabled, don't think that the money you have got is yours... You shall receive a rejection memo from the bank asking you to pay back the amount you have en cashed from that bank.
Google Adsense doesnt want to waste a single penny for the publishers whose accounts were disabled.

Google Adsense grows and learns as time passes by..

We can see that Google Adsense learns and adopts itself towards excellence. We could have seen some MFA sites using Adwords earlier which had very low rate per click. Nowadays we can see only service oriented websites using Adwords, which profits a publisher. Adsense grows and moves as the their team have planned. Let us hope the Adsense shall grow generating mutual benefits.
