Marketing funnel

    The model of the path from stranger to customer - awareness, consideration, preference, purchase, and in modern versions retention and advocacy. A simplification everyone argues with and everyone still uses, because it gives teams a shared map of where buyers drop and which activity works on which stage.

    Where it's used

    Used for planning, reporting and team alignment. Good for a shared picture of where people drop off, and it misleads when treated as a real path.

    How to calculate it

    Step conversion = People at this stage ÷ People at the previous stage

    Worked example

    Illustrative numbers

    In one quarter a SaaS ad reaches 500,000 people. Of those, 20,000 visit the site, 1,000 start a free trial and 150 pay.

    Ad to site visit

    20,000 visits ÷ 500,000 people = 4%

    Site visit to trial

    1,000 trials ÷ 20,000 visits = 5%

    Trial to paid

    150 customers ÷ 1,000 trials = 15%

    What it tells you

    Compare each step with a benchmark to see which is out of line. One extra point of trial to paid is often cheaper than getting the same result from more media.
