Google is taking active part in detecting and combating Click fraud as this is important to keep the advertisers happy. Their AdWords program is reportedly generating around 95% of its revenue, and the success of the programs rests on providing a profitable ROI for its advertisers.


The truth is that the battle is still mostly led privately. One just has to keep his eyes wide open and be the watchdog of the way his or her advertising activity performs. This constitutes an inconvenient for many advertisers as well as for publishers, who think their job would be to ensure quality content for their sites and not waste time sniffing around and keeping their eyes on the stats, thinking it's Googles job to ensure click safety.


They have taken steps in the direction of protecting advertisers, it has a quite complex monitoring system (analyzing a multitude of parameters beyond CTR) that uses both engineering systems and human analysis and they are on continuous activity of upgrading their detection mechanisms to combat fraudulent activity. Last year, they have also improved their smart pricing system, so as to charge the advertiser in accordance with the analysis of the probability of a click converting or not.


Once an invalid activity tracked this is what Google does:
  • Advertisers are not charged for clicks or impressions that were identified as fraudulent. Or refunds are made if the case.
  • Publishers are not judged starting from the assumption of innocence and are severely penalized without much debate: AdSense™ account dismantled. They give no guarantee for the possibility of account reinstatement although they state their opening for discussion, considering the possibility of sabotage.

Customizing Adsense Ads for better performance mainly involves choosing three aspects:

Ad Color:
By properly chosing the colors you use with your ads to match the theam of the over all website, it is possible to make the ads appear as an integral part of the website and less like Ads. This improves the chance of a visitor clicking on those.
The five parts of the ad which you can change the color on are:
  • The border color of the ad
  • The background color of the ad
  • The link color of the ad
  • The url color of the ad
  • The text color of the ad
  • By not choosing a border, that means the border color should be the same as the page background color
  • By choosing the Ad background color the same as the page background color
  • And choosing the text, url and link color in such a way to suit the existing colors used on the page.
  • Leaderboards and Banners are horizontal formats and are suitable to place on headers and footers.
  • On the verticle sections like left and right nav bars, you may use narrow or wide skyscrapers
  • When you want to places ads around or within the main content of the page, choose Buttons, Squares and Rectangles.

It is hard to generalize what colors should you use. The generally agreed theory is that the Ads should blend with the overall theame of the site and should compliment the content. You can bleand the Ads with the rest of the content:
Ad Format
Depending on where you want to place your Ads you choose the Ad Format. 
General guidelines of using these Ad formats.
Best style is determined based on how it fits best on your page. Using formats that have been very popular and overused (like banners and classic skyscrapers with a border) may not work very well in most cases as they tend to be ignored because they are instantly recognized as ads. Integrating them into the content gives good results.

Sometimes choosing image ads may work well and compliment your site if your site is purly content based with minimum graphics.

Borders
The commonly agreed recommendation is to not use borders. This means you should choose border color as the same as page background color. A border seems to act like a separator between the Ads and the content which is not a good thing in most cases.

Using a single password on the internet is often a recipe for disaster. One account creation on the wrong site, and all of your accounts can be compromised.

On the other hand, how can you remember all of these passwords for each site, and which one you used where? It's a herculean task of memory. To make your life easier, there is software that will take care of it for you. Never click on "Forgot your password again." Read on to learn more.

Many sites are starting to use Facebook's login technology to verify your account, which means the only password you'll need is the one for Facebook. To take advantage of Facebook connect, simply click on the Facebook icon. You'll see a small Facebook overlay verifying your attempt to log in using Facebook. Comply and you'll be logged in with a single click.

Using an online solution is great for sites that support those kinds of logins, but there are thousands of other sites that don't.
Browsers are another alternative. Most browsers store your passwords and will autofill them when you surf to a page it recognizes. The problem is when you upgrade your browser or if you ever have to reinstall, you lose all of those passwords in one foul sweep.

The best way to organize and secure your passwords under one is using software like Keepass (Windows, Linux, and Mac) or the Agile Web Solutions' popular 1Password software.
These applications will create very secure passwords for every site you create an account for and store it locally on your computer under a single password. When it detects a login, it will give you the option to fill in your account settings for you, using the password you enter or an ultra-secure password it has generated for you
