# JS Rendering

#### JavaScript Rendering for Google SERPs

{% hint style="info" %}

Some features load content dynamically through JavaScript, meaning the initial HTML source does not contain all the visible content rendered in the browser. \
To accurately capture such dynamic content, NetNut's SERP API offers **JavaScript Rendering** for Google searches via the `render` parameter.

This feature is specifically designed and optimized to handle complex Google SERP elements, including **AI Overviews, dynamic widgets, and JavaScript-driven search result blocks**, ensuring you retrieve fully rendered, complete SERP data.

**Parameter:** `render`

| Field           | Description                                                                                                                                                                                         |
| --------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Type**        | Boolean (`true` / `false`)                                                                                                                                                                          |
| **Default**     | `false`                                                                                                                                                                                             |
| **Description** | When set to `true`, the API will fully render the search result page, executing JavaScript before scraping. This is essential for pages where content loads asynchronously via client-side scripts. |

**Time & Performance**

The average processing time for rendered request is approximately **8-12 seconds**, though in many cases it may complete faster.

***

#### Example API Request with Rendering Enabled

```bash
curl --location 'https://serp-api.netnut.io/search?hl=en&rawHtml=1&googleDomain=www.google.com&q=Explain%20how%20photosynthesis%20converts%20light%20energy%20into%20chemical%20energy%20in%20plants&render=true' \
--header 'Authorization: Basic base64(username:password)'
```

***

#### Things to Consider

* **Rendering increases response time**, as it requires full page load and script execution.
* It is recommended to only use `render=true` when necessary (e.g., sites that heavily rely on JS).
* This feature currently supports **Google SERPs only**.
* **Rendering is a premium feature** with a different price tag than regular SERP requests.
