Conversion tracking for websites allows you to track:

Conversion tracking for websites specifically measures the actions users take on your website after interacting with your Twitter ads. This includes valuable events like purchases, sign-ups, or form submissions, directly linking ad exposure to on-site behavior. This data is crucial for optimizing campaigns and calculating return on ad spend. While knowing how long someone spent looking at an ad might be interesting, it's not the primary function of conversion tracking, which focuses on post-click/view actions. Detailed location information is typically gathered through other targeting or analytics tools, not directly through conversion tracking pixels, which are designed to report specific user actions on a website.
