Cached Page

Cached pages are saved copies of web pages that a search engine, browser, or other service has stored at a particular moment in time.

For instance, when Googlebot crawls your site, it takes a snapshot of each page and stores it on Google’s servers. That stored version is the cached page, and it allows you to view it directly through the search engine’s results to see how it looked the last time Google visited.

What is Caching?

There are two distinctions to keep in mind when it comes to defining caching. Browser caching is when your own browser saves and stores elements of a page, such as images and stylesheets, so when you return, it won’t have to download everything again and slow the process down.

On the other hand, search engine caching is when the likes of Google or Bing store a copy of an entire web page for their own purposes.

Both caching approaches improve the speed and efficiency of loading pages, but they exist for different reasons. The former is designed to help the individual visitor and the latter helps the search engine.

SEO Impact

For search engine optimisation purposes, cache can be a useful troubleshooting tool.

By checking Google’s cached version of a page, you can confirm whether the search engine has crawled any recent changes you’ve made. You can also see roughly when it last did so, as well as check how Google rendered the content, which can uncover problems where its interpretations of your site can be different from what users see.

Caching also provides a quick look into how search engines perceive your page. However, it’s also worth keeping in mind that Google retired its public “cached” link feature in its search results in 2024, meaning that even though pages are still cached, it’s impossible to track in the same way it once was.

The freshness of the most recent cache can also offer a sense of how frequently Google crawls pages. Crucially, the parts of your website that Google considers important are more frequently crawled and recached, while more obscure pages can sit with an old cached version for longer.

This ties into crawl budget and how Google prioritises its crawling, though it’s always an approximation rather than a precise figure.

Caching Configurations

For most website owners, cached pages are not something to actively manage. Instead, caching happens automatically, and the main practical relevance comes from its browser caching, where the process helps to contribute to page speed, the user experience, and Core Web Vitals.

While the old SEO habit of checking Google’s cache to debug crawling is no longer possible in the same way as before, the concept of caching remains a vital component of how a functional and fast website is built.
