I have found this presentation of Eye Tracking Study in 2009 , that focus on Social Website like Facebook, Twitter, Youtube.com that we can see how user behavior when they are using social media site. For this research , It will answer you this question. "Will people click the ads in social networking sites?
- The study found that 65% of participants engaged with sponsored ads within the first 10 seconds of their search.
- Scan paths do not follow the order of the search result positions. Often, sponsored ads were looked at before the third or fourth result.
- There is not a significant difference in fixation duration across the first four results or sponsored ads on both Facebook and YouTube.
- 50% of participants were satisfied with their brand search on Twitter. Many liked that they could find the most current opinions about a product.
