Here’s a really interesting blog post from the Google blog on how Google analyzes users’ searches using heatmaps.
Now, this is something that is very very interesting as I am a writing on the exact subject, “search”.
You can also do this type of test on your own website using CrazyEgg.
To see what the eye-tracking data we collect looks like, let’s go back to the results page we got for the query [how to tie a tie]. The following video clip shows in real time how a participant in our study scanned the page. And yes, seriously — the video is in real time! That’s how fast the eyes move when scanning a page. The larger the dot gets, the longer the users’ eye pauses looking at that specific location.
