SERP Heat Map

Hi..there!
Can any one tell about what is Google SERP Heat Map??


Thanks.

 

This is often about where the users eyes land and how they scan over the pages. Googling "Google SERP Heatmap" will show up a number of results. Basically it boils down to how much traffic (number of clicks) each result on the google results gets. For example the top spot gets over 40% (cant remember the exact number) of all traffic from people searching for that term. it diminishes from there. I just found a quick overview on youtube here

 

Thanks a lot.........even i don't know about this.
