Conversion Optimization

Most conversion tests never had enough traffic to mean anything

We run conversion programs on research rather than opinion, and we call tests on pre-agreed sample sizes instead of stopping the moment a variant looks good. When the honest answer is that your traffic can’t support testing yet, we say so and fix the obvious problems instead.

Replies within one business day. We’ll tell you if your traffic is too low before you pay.

“We ran tests and nothing ever won.”

Usually a sample size problem, not an ideas problem. The audit checks whether testing is viable at all. Start with the audit

“We know the funnel leaks but not where.”

Session recordings, funnel analysis, and form analytics locate it before we touch design. See the research

“Our traffic is modest.”

Then a testing program is the wrong purchase. We’d do a research audit and fix the found problems directly. Read who this isn’t for

“We want more leads without more ad spend.”

That’s the point of this. Same traffic, better conversion. See the plans

Three ways in

Research first, then test only if the traffic supports it

A testing program needs roughly 1,000 conversions a month to produce trustworthy results at reasonable speed. Below that, research and direct fixes beat A/B testing, and we’ll tell you which situation you’re in.

Start here

You need to know where the funnel leaks

For any traffic level. This is the honest first purchase and the only one that works at low volume.

Growth

Conversion is a company priority, not a project

For teams where CRO touches pricing, onboarding, and lifecycle, not just landing pages.

We’ll recommend the smaller tier if your conversion volume can’t justify this.

How it runs

How a test earns the right to launch

Most failed CRO programs fail on statistics, not creativity. This process is built around that.

  1. 01

    Research

    Weeks 1 to 2

    Analytics, session recordings, form analytics, and support tickets get read together. Support tickets are the most underused conversion research there is, because customers already told you what confused them.

    You leave with: A ranked list of real problems, each with the evidence behind it.

  2. 02

    Hypothesis and power check

    Week 3

    Each hypothesis gets a predicted effect size, then a required sample size and test duration. Anything that would need eight months to reach significance gets built directly instead of tested.

    You leave with: A test plan with sample sizes and stop dates fixed in advance.

  3. 03

    Build and QA

    Per test

    Variants get built and checked across browsers, devices, and screen readers. A variant that breaks on mobile Safari doesn’t just lose, it poisons the data.

    You leave with: A tested variant and a QA record, before a single visitor sees it.

  4. 04

    Call it honestly

    Per test

    Tests run to their pre-agreed sample size and get called against the rule set at the start. No peeking and stopping early, which is how most agencies manufacture winners.

    You leave with: A written result, including the losers and the inconclusive ones.

Honest fit

Worth booking, or worth looking elsewhere

This service is unusually easy to fake, because a stopped-early test always looks like a win. Two of these are reasons we decline work.

Worth booking

  • You have analytics running and can grant access.
  • You can ship front-end changes, or let us.
  • You accept that roughly half of all tests lose.
  • You can name what a conversion is worth to you.
  • You want the losing results reported too.

Look elsewhere

  • Your budget is under $1,200. The research audit is the floor, and testing below it is guesswork with extra steps.
  • You have under about 1,000 conversions a month. A testing program will not reach significance in useful time. Buy the audit and fix what it finds.
  • You want us to stop tests as soon as a variant looks ahead. That manufactures winners that don’t survive contact with reality, and we won’t do it.
  • You want a guaranteed lift percentage. Anyone quoting one before seeing your funnel is selling you a number, not a result.
  • Your product or pricing is the actual problem. No button colour fixes that, and we’ll say so in the research.
Before you ask

The questions that decide it

Something not covered? Ask directly and you’ll get a straight answer, not a calendar link.

How much traffic do we need?

Roughly 1,000 conversions a month to run a testing program that reaches significance in two to four weeks per test. Below that, tests take months and you’ll be tempted to call them early, which is worse than not testing. The research audit works at any traffic level and is the right purchase if you’re under that line.

What lift should we expect?

We won’t quote one before research, and treat any agency that does as a warning sign. What we will commit to is honest measurement, pre-agreed sample sizes, and full reporting of losers. Across a well-run program, roughly one test in three wins, one loses, and one is inconclusive.

Why do you insist on fixing sample size in advance?

Because if you watch a running test and stop when it looks good, you will find a winner almost every time, and it usually won’t hold. Fixing the sample size and stopping rule before launch is the difference between measurement and storytelling.

Do you report tests that lose?

Yes, in full, with the same detail as winners. A losing test that tells you customers do want the longer form is worth real money in decisions avoided. An agency that only shows you wins is either lucky, selective, or stopping early.

Can you run tests without our developers?

Usually yes, through a client-side testing tool for most changes. Anything touching checkout, pricing logic, or server-rendered content needs your developers, and we’ll say which is which during the hypothesis stage rather than discovering it mid-build.

What if the audit says we shouldn’t test?

Then you’ve saved yourself several months of retainer, and you still have a ranked list of real problems to fix directly. That’s a good outcome for you and an honest one for us. It happens on a meaningful share of audits.

Next step

Tell us where you think the funnel leaks

Send your funnel, your rough monthly conversion count, and where you suspect the problem is. We’ll tell you whether a testing program makes sense for you or whether the audit alone is the better buy.
