# Use custom request blocking

When a website loads, it sends requests to a number of different domains. Some requests are associated with loading page content, but others, like requests that serve ads, have nothing to do with the data you want to collect. The *Request Blocker* allows you to speed up agent processing and efficiency by blocking domain requests unrelated to page content.

### Apply request blocking

In the Agent Builder:

1. Select **File** > **Settings**.
2. Select **Request Blocking**.
3. Select the **level of request blocking** you would like to use:
  - **Level 1 - Standard** to block ads and analytics.
  - **Level 2 - Third-party** to block any URLs that do not match the starting.
  - **Level 3 - Event-Driven** to block additional events once the document is ready for data scraping.
  - **Level 4 - One Request** to allow only one request, which is for the HTML document itself.
4. **SAVE**.

In addition to the levels of Request Blocking add Auto-blocking expressions to customize your own Request Blocking expressions.
