Case study

Doubling daily installs by changing nothing but the screenshots

The Chrome Web Store gives a listing seconds to make its case, and the screenshots do most of the talking. One developer in the r/chrome_extensions community reported that after swapping their old screenshots for polished, captioned ones, their daily installs roughly doubled — with no change to the product itself.

The before: raw screen captures

The common failure mode is honest but unconvincing: a flat crop of the extension's popup or panel, no context, no caption explaining the value. It shows what the UI looks like, not why anyone should install it. On a crowded store page next to competitors, that reads as unfinished.

The after: a real listing kit

The fix isn't more features — it's presentation. Each screenshot wraps the real UI in a clean background, at the exact 1280×800 the store expects, with a short headline that names the benefit. The set reads as a deliberate pitch instead of a pile of screen grabs. That's exactly the kit Markee generates from a store URL: screenshots, promo tile, and marquee, sized to spec.

Why presentation moves installs

Users skim. When the first two screenshots communicate the value in a glance — legible text, obvious benefit, professional framing — more skimmers convert to installers. It's the highest-leverage change available to most extension developers because it's pure presentation: no engineering, no new features, just clearer images.
