How embedding works
Pick a widget, set the theme and size, copy one line of HTML and paste it into your page. It runs in its own frame, so it cannot clash with your site's styles, and it resizes itself if you use the loader.
-
Return on ad spend as a multiple and a percentage, with break-even ROAS from your margin.
-
Solve CPM, campaign cost or impressions from the other two.
-
Cost per click plus CTR, CPM, conversion rate and CPA from one campaign's totals.
-
Conversion rate from visitors and conversions, with an optional A/B comparison and z-test.
-
Social media engagement rate by followers and by reach, for one post or several.
-
Tag a URL with UTM campaign parameters, keeping its query and #fragment, then copy it.
No widget matches that search.
