Another way people say EPC is RPS (revenue per session). That latter is more common with people who got their start in e-commerce, the former more common with people who got their start in affiliate marketing, but they mean the same thing.
The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.
A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!
Specific to Facebook, dynamic ads are made of the standard conversion rate optimized content but the difference is in how Facebook deploys your ad. Dynamic ads are automatically shown to relevant audience members who have expressed digital interest elsewhere on the internet. For example, if someone visited your site and looked at a few products, Facebook dynamic ads will target them with your Facebook ads when they’re active on the platform.
Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
