Why speed maps to money for mobile app landing page
Install value is modest per user but volume and conversion rates are high, and almost all the traffic is mobile, where every 100ms is more expensive to deliver. A landing page is the simplest thing to make fast, so the speed work here is cheap relative to the lift it buys.
Where the load time goes. Ironically these single-purpose pages are often bloated with a marketing hero video, a font stack, and analytics. Inline the critical above-the-fold styles, swap the autoplay video for a poster image, self-host one font weight, and the store buttons paint almost instantly.

Questions & answers
- How much revenue can faster page speed add for mobile app landing page?
- On this profile (3s to 1.5s at 200K visits a month), the model puts the gain at about $33.6K a month, or $403.2K a year, from a roughly 15% relative lift in conversion. Your real numbers will differ; tune them in the calculator.
- Is the 15% conversion lift realistic?
- It comes from one assumption you can change: a 1% relative conversion change per 100ms faster, applied to the 1.5s this profile shaves off. That sensitivity is in the range of widely cited retail studies; for lower-intent traffic use a smaller figure, for high-intent checkout flows a larger one. The model also caps the modeled lift so an extreme speedup can't imply a fantasy multiplier.
