Page caching is a method of speeding up websites and web page load time by creating and storing a ‘snapshot’ of each webpage. These snapshots are delivered to website visitors rather than building a webpage dynamically for each page visit. See the video below to see page caching in action!
Here is what Google says about page speed:
You may have heard that here at Google we’re obsessed with speed, in our products and on the web. As part of that effort, today we’re including a new signal in our search ranking algorithms: site speed. Site speed reflects how quickly a website responds to web requests.
Speeding up websites is important “” not just to site owners, but to all Internet users. Faster sites create happy users and we’ve seen in our internal studies that when a site responds slowly, visitors spend less time there. But faster sites don’t just improve user experience; recent data shows that improving site speed also reduces operating costs. Like us, our users place a lot of value in speed “” that’s why we’ve decided to take site speed into account in our search rankings. We use a variety of sources to determine the speed of a site relative to other sites.
Enabling page cache is HIGHLY recommended. Watch this quick video to learn more:
