Children's camp invitations: who wins the parents, kids on camera or the founder?
Two creators invited parents to a children's camp. One built the video around kid reactions and a fast montage. One built it around the founder explaining the offer. Jeena ran both through real-viewer eye tracking and the gap that opened in the first seconds is already visible in the two hero stills.
Same trendy font, 117x the views. Eye tracking shows what the faceless guide missed.
Two creators taught the same trendy font in the same edit app. The person-led version pulled 117 times the views and 538 times the reposts of the faceless guide. Jeena ran both through real-viewer eye tracking, and the gap that opened in the opener is already visible in the two hero portraits.
Same hook, 372x the views. Eye tracking shows where the gap opens.
A copycat lifted the original creator's "Going viral didn't make me rich" hook beat for beat. The influencer got 372 times the views and 2,354 times the comments. Jeena's eye tracking shows the gap opened in the first second, and you can already see why in the two hero frames.
Wearing vs styling: two near-identical reels ran 44× apart. Jeena saw why.
Two outfit-transformation reels with the same format, the same "Wearing vs styling" on-screen title, and the same camera setup. One did 44× the views of the other. The gap doesn't live in the format. It lives in what viewer gaze did during the one-second window around the swap, and that is the kind of pattern only eye-tracking can see.
Pixar vs the dermatologist: which skincare video format wins, and why
Two creators tackled the same skincare question. One brought a dermatologist. The other brought Pixar-style 3D bottles. We ran both through Jeena and the eye-tracking data shows what flipped the numbers.

How to Test a Reel Hook Before You Post It
Your hook reads fine to you because you already know the payoff. A stranger does not. Four ways to test a hook before you post, from a free thumb-scroll check to a real-viewer eye-tracking panel, and exactly what a passing test looks like.
What to actually film for Reels: a small-business inventory
A practical inventory of seven short-video formats small businesses can actually film: behind-the-scenes, before-after, customer quote, how-it-works, one-mistake. Per format: the hook pattern, the typical payoff, and the trap to avoid.
What is a hook, really: the 1 to 3 second test every video has to pass
The hook is the first 1 to 3 seconds that decide whether the viewer stays. Five hook types that work, what each one is doing inside the viewer attention, and how each one breaks when it is used wrong.
How attention heatmaps for short video work, and what they show that web heatmaps cannot
Web heatmaps treat the page as a static layout. Video heatmaps add a time dimension that changes everything: hot zones move, the gaze pattern is vertical rather than F-shaped, and the most useful signal is where viewers are not looking. How to read each one, with the failure modes of both.
Fun, Contact, or Use: the three reasons people watch short video
Every short video that lands hits one of three payoffs: Fun (entertainment), Contact (recognition or connection), or Use (practical takeaway). A video that targets all three usually lands on none. How to pick the one yours is for, before you press record.
You only need 5 viewers to know if your Reel works. Here is why.
Jakob Nielsen showed in 2000 that five users catch about 85 percent of usability problems on a website. The same diminishing-returns curve applies to short video: five viewers surface the recurring failure modes; fifty mostly confirm what the first five told you. Why the small-n test is the right tool for content decisions, and where it stops working.
