What is Caching and why is it important ?
When a user visits your WordPress site, a series of operations are performed to dynamically generate the content. This process includes fetching data from the database, processing server-side scripts, and rendering the final HTML output. These steps can be resource-intensive and time-consuming, particularly for high-traffic websites.
Caching involves storing copies of frequently requested data in a temporary storage area known as a cache. This allows the server to quickly access and deliver the data to the user upon request, significantly reducing the waiting time for the user.
Here are some benefits of using Caching:
- Caching reduces load times by serving static content, enhancing user experience.
- It decreases the server’s workload, allowing it to handle more traffic.
- Faster websites rank higher in search results.
- Quick-loading sites increase user satisfaction and engagement.
- Efficient caching can lower hosting expenses.
- Caching helps manage traffic spikes effectively.
- Faster sites improve user engagement and conversion rates.
- A fast site enhances your brand’s credibility.
