Cached data is an important factor to consider when optimizing your website for search engines.

By taking steps to ensure that your cached data remains up-to-date and accurate, you can improve your website’s SEO ranking.

In this blog post, we will provide a definition of cached data, explain its importance in SEO, and share best practices when working with cached data.

What Is Cached Data?

Cached data is information stored by a computer to improve speed and efficiency.

Cached data is typically stored on the hard drive of a computer and accessed quickly when needed.

There are two types of cached data: active and passive.

Active cached data is information actively used by the computer.

Passive cached data is information that is not actively used.

Instead, the hard drive stores this type of data for later use.

Difference Between Cached Data and Cookies?

Cached data is a snapshot of content stored on a server to load it faster the next time a request arrives for it.

Cookies, on the other hand, are small text files stored on a user’s device to save information about their preferences and activity.

How Does Cached Data Work?

When you visit a website, your browser requests content from a server.

The server then sends back the requested information.

Your computer stores the cached data so that subsequent requests for the same content load faster.

What Is the Purpose of Cached Data?

The purpose of cached data is to improve speed and efficiency.

Cached data allows your browser to load content quickly, without having to request it from the server each time.

The process works well for increasing page speed while improving a visitor’s browsing experience and reducing data usage.

Different Types of Cached Data

There are four main types of cached data.

Use this information to help you more effectively understand how to use cached data alongside your SEO plan.

  • Site Cache: Site cache is when a website stores static files, like images and HTML pages, on the server Servers use this type of caching to help reduce load times. Websites load faster because the server doesn’t have to generate these files each time a user visits the site.
  • Browser Cache: Browser cache is temporary storage on your computer for files downloaded from the internet. The next time you visit a website, your browser will use the files stored in the cache to load the page faster. Browsers use cached data to improve overall performance.
  • Server Cache: Server cache is a type of caching that stores data on the server. The server type of caching can improve website performance because it reduces the amount of time needed to generate the page content.
  • Micro Cache: The micro cache is a type of caching that stores data in memory. Memory is faster than disk, so this type of caching can improve efficiency and performance by reducing the time needed to access data.

Example of Cached Data

On Moz.com, the company performed a cache-related case study that revealed how you can improve page speed via cached data.

The study helped an eCommerce store load faster than 98% of other tested sites.

Does Cached Data Affect SEO?

Cached data does not directly affect SEO.

However, it will indirectly impact SEO for WordPress sites by improving website performance.

Cached data can improve your website’s speed, which helps to improve the user experience.

Why Is Cached Data Important for SEO?

Site speed is a ranking factor for search engines like Google.

Cached data can help improve site speed by reducing the amount of time it takes for a web page to load.

The user will more effectively enjoy the experience on their next website visit because they won’t need to wait for pages to load.

Google notices that your visitors easily navigate the site and stay on it longer.

Improving the user experience like this will improve rankings over time.

Is Cached Data Necessary?

Cached data is not necessary for SEO.

Some sites will run quickly based on other SEO techniques, such as using a fast “out of the box” WordPress host.

However, you should strongly consider using cached data correctly to improve WordPress SEO results.

How Long Does It Take for Cached Data to Work?

Cached data works right away.

Once you save a file to the cache, it is available on the user’s next visit to the site.

The improvement in website speed and performance will occur immediately.

However, it may take some time for Google to notice the improved performance and update rankings accordingly.

Process of Clearing the WordPress Cache?

Here are the general steps to consider when clearing the WordPress cache.

We’ll assume that you use a WordPress cache plugin to perform this action.

  1. Log in to your WordPress site as the administrator.
  2. Go to the WordPress cache plugin settings page.
  3. Find the “Clear Cache” button and click it.
  4. Navigate away from your plugin with the WordPress cache successfully cleared.

How to Clear Cache in WordPress

If you’re not using a WordPress cache plugin, then you’ll need to follow the steps specific to your caching solution.

For example, some WordPress hosting providers offer caching features that you can clear from your hosting account dashboard.

Here are the steps to take when using cPanel, for instance.

1. Log Into cPanel

The first step is to log into cPanel.

You can do this by going to yourdomain.com/cpanel.

2. Enter Credentials

After you enter your domain name, you’ll arrive at a login screen.

Enter your cPanel username and password.

These are the same credentials that you use to log into your WordPress site.

3. Click on the “Files” Section

Once you’re logged in, look for the “Files” section and click on it.

4. Find the “File Manager” Option

Under the “Files” section, you should see an option called “File Manager.” Click on that.

5. Select the Folder You Want To Empty

A pop-up window will appear. In that window, select the folder that you want to empty.

The WordPress cache is usually stored in the “wp-content/cache” folder.

6. Click on the “Empty Selected” Button

Once you have selected the folder, click on the “Empty Selected” button.

7. Confirm That You Want To Empty the Cache

A confirmation message will appear.

Click on the “Confirm” button to confirm that you want to empty the cache.

Another simple way to clear the WordPress cache is through your WordPress host’s dashboard.

Many hosts include an area in the dashboard where you can click a button to clear the website cache.

After logging into your WordPress hosting account dashboard, look for a caching option.

It is usually found in the “Performance” or “Cache” section.

Once you find the caching option, look for a button that says “Clear Cache” or “Empty Cache.”

Click on that button to clear the WordPress cache.

Cached Data Best Practices

Here are three of the most important best practices to keep in mind when dealing with clearing a cache in WordPress.

Avoid Caching Dynamic Pages

The first rule of caching is to avoid caching dynamic pages.

A dynamic page is a page that changes based on user input, such as a search results page or a shopping cart page.

Caching these types of pages can cause problems because the cached version may not reflect the most recent state of the page.

Use a Caching Plugin

If you are going to cache static pages, then the best way to do it is with a caching plugin.

A caching plugin will create static HTML files of your pages and serve those files instead of processing the heavier WordPress PHP code.

Don’t Cache Pages for Logged-In Users

Another best practice is to avoid caching pages for logged-in users.

If you cache a page that a user logs into, then they may not see the most recent version.

It can create confusion for your user and may even lead to data loss.

One last tip is to create a backup of your website before clearing the cache or making any other changes to your website.

It will ensure that you can always revert to a previous version if something goes wrong.

Cached Data Tools To Save Time and Money

It’s tough to deal with cache-related issues without the appropriate tools.

Let’s take a look at some of the available cached data solutions.

What Is a Cached Data Tool?

A cached data tool is software that helps you manage your cached data.

You can use these tools to view, edit, and delete cached data.

Cached data tools can also help you automate the process of clearing cache.
