# 🎬 Lazy load iframes and videos

{% hint style="info" %}

### Who can use this feature?

Lazy load (iframes and videos) is available on the **Pro** and **Expert** plans.
{% endhint %}

### What is Lazy load (iframes and videos)?

Embedded videos and maps are heavy. A single YouTube embed can pull in more data than your entire page. If you load them all at once, your store crawls.

With this on, embeds stay paused until customers scroll near them. The rest of your page loads quickly first.

This covers:

* YouTube and Vimeo videos
* Google Maps
* Other iframe embeds

### Why use Lazy load (iframes and videos)?

* **Cuts the heaviest page weight** — a single video embed can outweigh your whole page; deferring it loads your content first.
* **Faster initial load** — embeds wait until customers scroll near them.
* **Better Core Web Vitals** — less upfront data means a quicker first paint.
* **No visual change** — videos and maps still appear normally as customers reach them.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.appplaza.app/speed-optimizer/speed-up/lazy-load-iframes-and-videos.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
