I can tell exactly when my website visitor looks at it from top to bottom in seconds even if there are thousands or millions visiting simultaneously; this data helps me adjust accordingly! There isn't anything about eye-tracking we dislike so far--it's very intuitive for nontechnical users/people who have never used an AIDA site before (like us). It doesn’t track mouse movements which makes things difficult sometimes but with some patience you'll get past those issues too once everything works as intended like any other software out there such has Adobe Acrobat Pro etc.,etc.; also don' be afraid because many more technical aspects will come along over time after getting familiar wth its main features & capabilities just keep trying ;-).
