Tracking incoming CPM costs

Most traffic sources deal in CPC (cost per click) pricing. They pass the actual click cost in real time using a token like {cost}. However, some sources pass a CPM (cost per mille/thousand impressions) bid instead. This article explains how to handle both scenarios in FunnelFlux.

Passing CPC cost values

Some traffic sources pass cost per click in real time, usually with a token like {cost}.

Add this token to the cost / CPE field in your traffic source settings:

Handling CPM bid values

Some traffic sources pass a CPM bid rather than a cost per click. For sources like pops or redirects, this value will be roughly 1000x the actual per-click cost.

To handle this, prepend cpm_ before the cost/bid token:

In a live URL, this appends ...&c=cpm_12.34 to the URL. The FunnelFlux edge server detects the cpm_ prefix and divides by 1000 automatically. For example, it calculates 12.34 / 1000 = 0.01234 as the cost per click.

Found a template that needs updating?

If you find a traffic source in our templates where the cost token is present but should have this modifier added, please let us know.
