Cost per lead means nothing without the funnel under it. Enter spend and your own conversion steps — every default is an editable example, not a benchmark.
No — and treat anyone quoting you one universal funnel as a red flag. Use your own CRM’s stage history; the tool is only as honest as the rates you enter.
Because spend is fixed at the top of the funnel — every stage you lose upstream divides the same dollars across fewer closings. That sensitivity is the point.
Yes — run it once per channel with that channel’s spend and rates, then compare cost per closed deal, never cost per lead.
