Which search engines cache web pages they crawl?
Technically,…. ALL OF THEM, but not all of them make the cache available, all engines cache the page so the can effectively and efficiently index the content and also experiment with the content when trying new alorithms and different scenarios. Another reason they like to cache but doesn’t apply anymore is just as recently as ten years ago, web sites weren’t as reliable since the proliferation and acceptance of the web as a resource or tool wasn’t the common theme and this let web site operators take their sites down for periods of time for maintenance and upgrades and some even brazenly during the day. This unreliability factor and lack of availability created difficulties for search engines which tried to index content without replicating it to a local cache.
