Definition
A marketing funnel is a model that maps the staged journey prospective customers take from first awareness through to purchase (and beyond), used to identify where prospects drop off and where to invest in conversion improvements.
The classic funnel — awareness, interest, consideration, intent, evaluation, purchase — is a simplification, but a useful one. Real customer journeys are messier (they loop, restart, involve multiple stakeholders), but the funnel framework still helps you identify the specific stage where the math is breaking and where one intervention will move the entire pipeline.
Modern funnels add post-purchase stages — retention, expansion, advocacy — because in subscription and recurring-revenue businesses, the funnel doesn't end at the first sale. The full funnel runs from first touch through customer success.
Origin
The concept dates to E. St. Elmo Lewis's AIDA model (1898). The modern funnel terminology was formalised in B2B marketing in the 1990s and 2000s and extended to recurring-revenue businesses in the SaaS era.
How it works
- Define the stages relevant to your business (typically 4-7 stages).
- Instrument each stage in analytics — every transition must be measurable.
- Compute conversion rates between stages.
- Identify the lowest-converting transition — that's where intervention has highest ROI.
- Test improvements at the bottleneck stage; measure the lift.
- Repeat — the next bottleneck moves once you fix the first.
When to use it
Use when
- Any time you're allocating marketing budget across channels and stages.
- When diagnosing pipeline problems.
- When designing nurture sequences.
Skip when
- For very short, single-touch transactional flows.
- When the funnel becomes a fiction that doesn't reflect actual customer behaviour.
Key metrics
- Stage-to-stage conversion rates
- Total funnel conversion (top to bottom)
- Time-in-stage (how long prospects sit at each step)
- Drop-off rate per stage
Examples
- Our top-of-funnel was healthy but middle-of-funnel converted at 4%. Fix that, double the pipeline.
- We mapped the actual customer journey and discovered it had 11 stages, not the 5 we'd been measuring.
- Every channel got measured on its full-funnel conversion, not just CTR.
In practice at Makreate
Every Makreate growth engagement starts by mapping the client's actual funnel — not the funnel they wish they had. We instrument every stage transition, then build a single live dashboard that shows where prospects actually drop off. Most clients discover within the first week that their bottleneck is one stage they hadn't been measuring at all, and one targeted intervention there moves the entire pipeline.
Advertising →Common mistakes
- Designing the funnel around what's easy to measure instead of how customers actually behave.
- Optimising the top of funnel when the bottleneck is in the middle.
- Not measuring stage-to-stage conversion rates.
- Treating the funnel as linear when real journeys loop.
- Stopping the funnel at first purchase in a recurring-revenue business.
Frequently asked
How many stages should a funnel have?
Typically 5-7. Fewer than 4 misses important transitions; more than 8 becomes unmeasurable.
Is the funnel still relevant in a non-linear customer journey?
Yes — as a measurement framework, not a description of the literal path. Customers loop and restart; the funnel still tells you where the math breaks.
Does the funnel include post-purchase stages?
For subscription and recurring-revenue businesses, yes — retention, expansion and advocacy are part of the full funnel.
