# 🔥What is the difference between Event ID and pixel ID?

In Twitter, an "Event ID" and a "Pixel ID" serve different purposes in the tracking and measurement of advertising campaigns.

A Pixel ID is a main pixel that is created automatically by Twitter. The Pixel ID is used to track Page view events only. One Business account can only create only 1 pixel ID.

On the other hand, an Event ID is a unique identifier assigned to a specific event or action that you want to track on your website or mobile app.

For example, you can use Event IDs to track when someone clicks on a specific button or makes a purchase on your website. This allows you to measure the effectiveness of your Twitter Ads campaigns in driving specific actions on your website.
