Similar Font Size For Best AdSense Results?

The official Google AdSense blog reports on the ad optimization of website Engineeringtalk. Quote (my emphasis): “They found the biggest influence on CTR [click-through-rate] was the similarity between the AdSense type (size and font), and the main body text of the page. The more similar the type, the higher the CTR.�
I’m certain this tip, and many other AdSense optimization tips, can be wrapped up by saying “make the ads look more like your normal content.� However, some of these approaches – certainly not using a similar font, but e.g. putting the ads right inside the content – can turn into barriers for reading the main content. And of course, that hurts the site (and ads) in the end.
