Trackers and ads significantly increase page load time. A single page delay may not seem huge, but over a lifetime of browsing (and data usage) that wasted time stacks up. Ghostery Lite has employed a page performance visualization feature to allow users to see the effect Lite has on page load speed, as well as the load time of pages when Lite is paused. Page load speeds range from fast (0-5 seconds), medium (5-10 seconds) and – slow (10+ seconds). When reviewing page load times it is important to take into consideration that some great sites are ad and tracker-free, and will load quickly regardless of the presence of an ad and tracker blocker.
