Make your site’s pages instant in 1 minute and improve your conversion rate by 1%
Amazon and others found that 100 milliseconds of latency is responsible for 1% in sales.
But latency on the web is hard to overcome.
instant.page uses just-in-time preloading — it preloads a page right before a user clicks on it.
Before a user clicks on a link, they hover their mouse over that link. When a user has hovered for 65 ms there is one chance out of two that they will click on that link, so instant.page starts preloading at this moment, leaving on average over 300 ms for the page to preload.
On mobile, a user starts touching their display before releasing it, leaving on average 90 ms to preload the page.
You can also click the menu
to experience it.
Cheating the brain
The humain brain perceives actions taking less than 100 ms as instant.
As a result, instant.page makes your site feel instant even on 3G (assuming your pages are fast to render).
Easy on your server and your user’s data plan
Pages are preloaded only when there’s a good chance that a user is going to visit them, and it preloads only the HTML of that page, being respectful of your users’ and servers’ bandwidth and CPU. It’s 1 kB and loads after everything else. And it’s free and open source (MIT license).
