# Recommended default settings for LiteSpeed Cache

> Suggested LiteSpeed Cache for WordPress tweaks beyond the defaults: domain key, cache, purge, ESI, WooCommerce, and page optimization.

The LiteSpeed Cache plugin ships with sensible defaults. You often only need a few changes. Apply the sections below in the WordPress admin where they match your site.

## General

In **LiteSpeed Cache → General**, request a **Domain Key** if you have not already.

## Cache

Open **LiteSpeed Cache → Cache**.

### Cache Mobile

Set **Cache Mobile** from **Off** to **On** only if your site is **not** responsive or it depends on mobile-detection logic. Otherwise leave it as suits your setup.

### Drop Query String

Under **Cache**, use **Drop Query String** for tracking parameters. If you installed **v3** of the plugin, this is already set. Typical values include:

```
fbclid
gclid
utm*
_ga
```

Add or adjust entries to match the query strings you want ignored for caching.

## Purge

Open **LiteSpeed Cache → Purge**.

### Auto purge rules for publish/update

Under **Auto Purge Rules for Publish/Update**, make sure **All pages** is **unchecked** unless you intentionally want that behavior.

### Serve stale

Set **Serve Stale** from **Off** to **On**.

## ESI

Open **LiteSpeed Cache → ESI**.

Set **Enable ESI** from **Off** to **On** only if your site relies on **WordPress nonces** in a way that benefits from ESI. If you do not need that, you can leave ESI off.

## WooCommerce

If you use WooCommerce, open the **WooCommerce** tab.

Under **Product Update Interval**, choose **Purge product and categories only when the stock status changes** if you use WooCommerce **and** your store does not depend on live **quantity** for display or logic.

## Page Optimization

Open **LiteSpeed Cache → Page Optimization**.

Under **Optimization Settings**, set **Remove WordPress Emoji** from **Off** to **On** unless you need front-end emoji scripts.
