ENTRY PRODUCTS

Productised. Single deliverable. Five working days to two weeks.

£500

AI Headline Lab

5 working days

Twenty AI-generated headline variants ranked against your buyer’s actual language. Tested-ready copy for A/B against live traffic. You leave with the variants and the hypothesis library.

£1,500

Speed Sprint

2 weeks

Core Web Vitals fix. Conversion-aware speed work on the highest-leverage pages. Before/after numbers tied to actual revenue, not PageSpeed scores. BeeFRIENDLY went $48K to $1.45M annual revenue from a 2.24-second LCP reduction.

£2,500

Pricing Experimentation Audit

2 weeks

Promo-window pricing experiments at 99% statistical significance. Structured to survive the scaling test, not spike on Black Friday weekend. Enzymedica went 3.4% to 16.9% this way.

SERVICE TIERS

Sustained. Multi-page. Compounding wins per quarter.

£2,500

Sprint

1 month

Single high-leverage engagement. Rebuild a page, ship five hypotheses at 99% confidence, deliver the lift report. The work every store has on its punch list but never gets to.

£2,500/mo

Growth

3-month minimum

Sustained CRO programme. 8-12 tests per quarter at 99% confidence. Monthly report tying every change to revenue. The size most £100K-£1M monthly stores need to break the stagnant conversion plateau.

£5,000/mo

Scale

Performance-guaranteed

Full operator-led-AI programme. 30+ experiments per quarter. Monthly report. The 28-34% conversion-lift band Build Grow Scale’s 347-store research documents is the standard, not the goal.

FULL-SERVICE TIERS

How to choose between Sprint, Growth, and Scale

The three tiers solve three different problems. Pick by which problem you currently have, not by which sounds most comprehensive.

Choose Sprint if you have a single, well-defined CRO hypothesis

Sprint (£2,500, 2 weeks) is right when you already know what you want to test. Example: you have a pricing page where the middle tier converts at 1.4% and you want to know whether adding a comparison table would lift trial-to-paid. Sprint runs the diagnostic, builds the test, ships it live with the 99 Rule applied, and hands back the result with a clear winner-or-no-winner verdict.

Sprint is not right if you have multiple competing hypotheses or no clear test priority. In that situation, the diagnostic phase needs to be longer than 2 weeks allows.

Choose Growth if you need an ongoing testing programme

Growth (£2,500/month, 3-month minimum) is right when you have steady traffic (10K+ monthly visitors on the page you're testing), a backlog of hypotheses, and need someone running the programme weekly. Growth typically delivers 4-6 confirmed wins over 3 months, with cumulative lift of 14-22% on the optimised surfaces.

Growth is not right if your traffic is below 5K monthly visitors per surface — the 99 Rule won't reach significance within reasonable run lengths and you'll get false-negative results.

Choose Scale if you need a measurable conversion lift in 6 months

Scale (£5,000/month, 6-month minimum, 90-day conversion lift guarantee) is right when conversion lift is a board-level priority and you need accountability tied to outcome. The 90-day guarantee means if we haven't produced a measurable, statistically significant lift within the first 90 days, the rest of the engagement is free until we do.

Scale typically delivers 28-34% cumulative conversion lift over 6 months across the prioritised surfaces. The lift compounds because each confirmed win stays in the programme — we don't roll back wins to test new variants.

The three productised entry products

For situations where a retainer doesn't fit, we offer three productised entry products that solve specific problems for a one-off fee:

AI Headline Lab — £500

Three AI-generated headline alternatives for your hero, each with the reasoning behind the variation (specificity vs benefit-led vs social-proof-led). Delivered in 5 working days. Right for landing pages, product pages, and email subject lines where headline copy is the bottleneck.

Speed Sprint — £1,500

Page-speed audit plus implementation of the top 5 lift-producing speed fixes. Targeted at Largest Contentful Paint (LCP) and Interaction to Next Paint (INP). Delivered in 10 working days. Right for stores where page-speed is hurting conversion (LCP above 2.5s).

Pricing Experimentation Audit — £2,500

A 4-week pricing-page audit covering tier structure, anchor placement, comparison table format, FAQ block coverage, social proof, sticky CTA, and 99-Rule test design for the top 3 hypotheses. Delivered as a written audit plus a 60-minute walkthrough call. Right for SaaS pricing pages, ecommerce pricing pages, and services pricing pages.

What's not included (so there are no surprises)

None of the tiers include: paid media management, SEO content writing, brand work, custom development beyond test implementation, or design work outside the testing surfaces. We focus narrowly on conversion-rate optimisation because that's where the operator-led work compounds. For paid media or SEO content, we recommend specialists — we have a referral list of agencies we trust on those surfaces.

Full-Service CRO Engagements

Beyond the productised entry products above, GoGoChimp offers three full-service CRO engagement tiers — each with hypothesis-led testing, AI-accelerated variant generation, and downstream-metric audit.

  • Sprint — £2,500 one-off. A single-test conversion sprint. Hypothesis, variant, ship, audit, report. 4-6 weeks. Best for one specific page or funnel step you want to fix fast.
  • Growth Plan — £2,500/month. Ongoing CRO programme. 2-3 tests/month, full-funnel analysis quarterly. No long-term contract. Best for £500K–£5M/year businesses building a testing programme.
  • Scale Plan — £5,000/month + 90-day guarantee. Full-funnel CRO + AI variant production + dedicated engineering + statistically rigorous testing. We’ll guarantee a measurable lift within 90 days or extend the engagement for free. Best for £5M+/year businesses where compounding wins matter.

All three tiers operate under The 99 Rule (99% statistical-significance threshold, no peeking, downstream-metric audit) and use the OperatorAI methodology. Compare against other UK CRO agencies on the Best CRO Agency UK 2026 comparison page.

CONSULTANT VS AGENCY

Considering a freelance CRO consultant instead?

Productised services vs ongoing consultancy is a structural choice. Consultants advise; agencies execute. The right answer depends on whether your team can run a testing programme or whether you need it run for you.
