What is the distribution of clicks on a search engine results page? What percentage of clicks gets each search result according to its rank? How much more users’ attention gets the first listing compared to the second? Or how often do users click the listing below the page fold? The way users interact with SERPs is one of the most frequently discussed topics in the SEO community and is also a very important field of study for the search engine specialists. To answer the above questions researchers employ the so-called eye tracking experiments.

Eye-Tracking Studies

The objective of eye tracking studies is gaining insight into how users browse the presented abstracts and select links to click. The results of eye tracking research provide Internet marketers with information on clickthrough rates, thus allowing them to make correct predictions on traffic changes as their rankings are gained or lost. For SE engineers the results provide a basis for improving the interfaces of search engines and metrics to evaluate the relevancy of the presented search results.

To detect users’ interaction patterns the eye tracking experiment observes a number of indicators of ocular behavior using a CCD (charged couple device) camera similar to the appliance used to read bar codes. The indices of ocular behavior include eye fixations, saccades, scan paths and pupil dilation. Eye fixations are defined as a stable gaze lasting for 200-300 milliseconds representing visual attention to a specific area of a SERP. Pupil dilations or pupil diameter changes represent a measurement of interest in a particular listing. This variable is especially important as it helps interpreting an implicit user feedback to the relevancy of the presented search results.
