Caching is a technique used to speed up WordPress websites by reducing repeated processing.

Without caching, WordPress must generate each page from scratch for every visitor.

What Caching Does #

Caching:

• Stores generated pages temporarily
• Reduces PHP execution
• Reduces database queries
• Improves load times

Visitors receive pre-generated content instead of dynamic processing.

Why WordPress Needs Caching #

WordPress:

• Is database-driven
• Uses PHP for every page request
• Can become slow without optimization

Caching significantly reduces server load.

Types of WordPress Caching #

Common caching types include:

• Page caching
• Browser caching
• Object caching

Most users interact with caching via plugins.

Caching and WP Toolkit #

WP Toolkit:

• Does not automatically configure caching
• Does not force caching plugins
• Allows you to manage WordPress freely

Caching choices are customer-controlled.

When Caching Helps Most #

Caching is especially useful when:

• Traffic increases
• The site has many plugins
• Pages are content-heavy
• The site is publicly accessible

Even small sites benefit from caching.

Common Caching Mistakes #

• Using multiple caching plugins
• Enabling aggressive caching without testing
• Caching admin pages
• Forgetting to clear cache after changes

Improper caching can cause display issues.

Responsibility Notice #

You are responsible for:

• Choosing a caching method
• Configuring caching plugins
• Clearing cache when needed
