## LiteSpeed Cache Crawler

The crawler tool reviews your site for old content and updates the existing cache. This ensures that visitors see the most up-to-date content when they view your website. For example, if you updated a page’s content recently, a visitor may see the older version “cached” version of the page.

You can run the crawl manually or set up a cron job to automatically crawl your site on a set schedule. Here are the steps.

1. [Login to your WordPress Dashboard](https://www.inmotionhosting.com/support/edu/wordpress/logging-into-wordpress-dashboard/).
2. Click the **LiteSpeed Cache** then **Crawler** link in your navigation menu.

4. This will take some time to complete. You can click the **Show crawler status** button to see the progress.![Viewing Crawl Status](https://www.inmotionhosting.com/support/wp-content/uploads/2021/02/show-crawler-status.png)

7. Switch the *Crawler* option to **ON**.![Enable Crawling Cron ](https://www.inmotionhosting.com/support/wp-content/uploads/2021/02/enable-crawler.png)
8. Click the **Save Changes** button.

It will now automatically re-crawl your site on the set interval and update your site cache.

## WordPress Optimization Tools

Now that you have your site caching set up, we will go over the additional tools available that are included with the LiteSpeed Cache plugin. These can help improve the performance of your WordPress site.

### CDN Tools

A **content distribution network** (CDN) stores parts of your content such as images on a separate server from your website. These CDN servers are typically optimized for a specific type of content. Often they are also in different locations so they can “distribute” the content globally. 

Here is how to enable the CDN settings in the LiteSpeed Cache plugin. You will also need to enable the CDN service in your QUIC.cloud account.

1. [Login to your WordPress Dashboard](https://www.inmotionhosting.com/support/edu/wordpress/logging-into-wordpress-dashboard/).
2. Click **LiteSpeed Cache** then **CDN** in your navigation menu.
3. Set the *QUIC.cloud CDN* option to **ON**.![Turning CDN On](https://www.inmotionhosting.com/support/wp-content/uploads/2021/02/enable-cdn.png)
4. Click the **Save Changes** button.
5. Login to your [QUIC.cloud](https://quic.cloud/) account.
6. Select your site from the **Domains** list.
7. Under *Service* click the **CDN** option.
8. Click the Enable CDN button.![Enabling CDN Service](https://www.inmotionhosting.com/support/wp-content/uploads/2021/02/enable-quic-cdn.png)
9. Select the “**I want to use CNAME**” option.![Using CNAME Record](https://www.inmotionhosting.com/support/wp-content/uploads/2021/02/use-cname.png)
10. You must then [create a CNAME record](https://www.inmotionhosting.com/support/domain-names/create-cname-record/) with the provided text.
11. Click the **Continue** button. The CDN will then begin working once your CNAME change has been verified. Please note that this change may take up to 24 hours to [propagate](https://www.inmotionhosting.com/support/domain-names/dns-nameserver-changes/complete-guide-to-dns-records/#propagation).

### Image Optimization

1. [Login to your WordPress Dashboard](https://www.inmotionhosting.com/support/edu/wordpress/logging-into-wordpress-dashboard/).

### Page Optimization

The LiteSpeed Cache plugin includes a wide array of page optimization features, we’ll now show you how to access them. Since specific site setup can differ, we recommend only adjusting settings that you are familiar with. Also, test your website extensively after making any changes here.

5. Click the **Save Changes** button after making any changes.
6. Be sure to Purge All Cache as described above.

### Database Optimization

Keeping your database free of old or unused content is another important way to ensure your site is running smoothly. For example, you can use this plugin to quickly delete all “Spam” and “Trashed” comments, or “Post Revisions” with just a single click. 

1. [Login to your WordPress Dashboard](https://www.inmotionhosting.com/support/edu/wordpress/logging-into-wordpress-dashboard/).
2. Click **LiteSpeed Cache**, then the **Database** link in your navigation menu.
3. You can then select the specific database element that you want to clean up. You can also click the **Clean All** button to remove them all at once. It will immediately perform the cleanup process.![Optimize WordPress Database](https://www.inmotionhosting.com/support/wp-content/uploads/2021/02/database-optimization.png)
