Benchmarking without fooling yourself

Dear founder,

Someone always shares a chart claiming the average eCommerce conversion rate is some tidy figure, and half the founders reading it panic. I understand why. But most benchmarks are far shakier than they look, and taken the wrong way they'll send you chasing the wrong things.

Why most benchmarks mislead

A single average hides enormous variation. Your numbers depend on things the benchmark can't see.

• Your traffic mix — cold ads convert nothing like returning email subscribers
• Your price point — a two hundred pound product converts slower than a tenner
• Your category — impulse buys and considered purchases live in different worlds
• How the figure was measured — nobody counts sessions quite the same way

Compared against a blended average of thousands of dissimilar stores, your number is almost meaningless.

How to benchmark usefully

The most honest benchmark you have is your own past.

1. Compare this month to the same month last year, like with like
2. Segment before you judge — new versus returning, mobile versus desktop
3. Use external benchmarks only as a rough range, never a target
4. Ask whether the source actually resembles your kind of business

The most useful comparison is you, last quarter. Beat your own numbers and you're genuinely improving, whatever the industry chart says.

Benchmarks are a compass for a gut check, not a scoreboard. Let them reassure you that you're roughly in the right area, then get back to improving on yourself. If a scary statistic has you doubting a store that's actually doing fine, book advisory time and we'll put it in proper context.
