I visited
LiewCF.com and find that his idea for Adsense placement ingenius.
He highlights two of his "hottest" articles and continues it with the Adsense ads.
The effect is that it blends into one big block of text link which has the top half linking to the
real contents of LiewCF own site and the other half which is actually Google Ads. It almost fooled me into clicking the other Adsense links thinking it was LiewCF content.
Will implement it in my other websites. I'm sure the click-thru rates are pretty high for ads like this.
