Dramatically speed up your WordPress site and make navigation effectively instant by loading the next link on hover.

The InstantClick settings page
InstantClick dramatically speeds up your website, making navigation effectively instant in most cases. This plugin is the easiest way of adding InstantClick to your WordPress theme.
Before visitors click on a link, they hover over that link. Between these two events, 200 ms to 300 ms usually pass by (test yourself here). InstantClick makes use of that time to preload the page, so that the page is already there when you click.
See InstantClick.io for more information on InstantClick.
This plugin simply adds InstantClick to your website using the WordPress scripts API. Some customization may be required.
