# Impression Region Using Dynamic Content

Once your account has been configured with Impression Tracking, track the performance of the dynamic content block, rules, and content by using impression tracking reports.

The Impression Region name is automatically created with the dynamic block position, dynamic block name, rule name, and content block name. There are double underscores that concatenate these items together in the field name. For example, the Impression Region name can be updated to 01\_\_Left\_\_Biking\_\_Image. The field has a maximum character limit of 60, so we recommend keeping the name short.
