How does Strossle measure impressions?

Joakim Stenberg Updated by Joakim Stenberg

We only measure viewable impressions.

Once the recommendation (e.g. an article or an ad) is coming into view on the visitors device we append a background-image to the recommendation slot, triggering an impression event. These impression events are collected by our servers and ends up in e.g. widget- and campaign reports.

How did we do?

Will the Strossle widget slow down my website?
