Sales Funnel

A sales funnel is the narrowing path from stranger to customer, staged as awareness, interest, consideration, and purchase.

What a sales funnel is

A sales funnel is the path from stranger to customer, drawn as narrowing stages: awareness, interest, consideration, purchase. Many enter, fewer pass each stage, some buy.

Marketers shorthand the stages as top, middle, and bottom of funnel: TOFU, MOFU, BOFU.

Why the funnel matters

It locates the problem. “Sales are down” says nothing; “consideration-stage visitors aren’t converting” points at specific pages and specific fixes.

What each stage needs

  • Top: discovery through content, ads, and word of mouth
  • Middle: evaluation material, comparisons, reviews, Q&A
  • Bottom: the offer, checkout ease, and final reassurance
  • After: post-purchase experience that refills the top

Frequently asked questions

Is the funnel outdated as a model?

Real journeys loop and skip stages, so the funnel simplifies. It stays useful as a diagnostic frame even when the path isn’t linear.

Where do most ecommerce funnels leak?

Between interest and purchase: the product page and checkout. That’s where doubt, cost surprises, and friction concentrate, and where fixes pay fastest.
