http://ping.fm/qRoVl Google PPC: Content or Search?

When advertising with pay per click Google gives the advertiser two broad options. Advertising in search results, advertising in websites content or indeed many choose to do both. Advertising in search means that results are displayed in Google under searches, and in its distributors search results. Google content advertising applies to those websites who choose to incorporate ìAdsenseî into their websites. As adsense rapidly expands, it is now viewable on millions of web pages throughout the web. However, many advertisers are shunning this in favor of merely advertising in search results.
There are several reasons for this, and the first is trust. This has been a result of smaller websites, through to adsense empires choosing to embark on Click Fraud. Although this issue occurs in search it is far less dominant. Those who commit Click Fraud on search are those trying to weaken a competitorís ROI. With Adsense the same applies, along with the website owner trying to increase his revenues using similar tactics.
