What is a Cached Page?
A cached page is a copy of a web page stored in temporary storage, or “cache,” to improve data retrieval performance. Caching allows quicker access to frequently visited pages by storing HTML files, JavaScript, and images locally on a user’s device or on proxy servers.
Types of Cache:
- Browser Cache: Stores web page data on the user’s device to reduce load times for revisits.
- Server Cache (CDNs): Stores copies of web pages on proxy servers worldwide, delivering content from the nearest server to the user.
Importance:
- Speed: Reduces load times by serving pre-stored content.
- Bandwidth Efficiency: Lowers bandwidth usage by avoiding repeated data downloads.
- Search Engine Backup: Google caches pages to provide backup access if the live page is unavailable.
Managing Cached Pages:
- Prevent Caching: Use Robots meta tags, like
<Meta Name="GoogleBot" Content="Noarchive">
, to prevent Google from caching your pages.
