The 7 Birmingham CRO agencies we checked

Each profile gives the agency’s approach in two short paragraphs, then the reasons to pick it and the reasons to think twice.

1. Get-Found: Test Discipline

A Shopify and performance agency at Steamhouse on Cardigan Street, Get-Found runs CRO in four steps: audit, hypothesis, A/B test and ship.

It sets 95% confidence and 80% statistical power before a test starts, and codes winning changes straight into the site rather than leaving a testing script in place.

Why choose them	Think twice if
Clear testing rules set before any test runs; winners coded into the site; free 13-point audit	Low-traffic sites may wait weeks for a result

2. Opace: Published Price

With more than 15 years in business, Opace works with ecommerce, SaaS, lead generation and service businesses from 11 Brindley Place.

Its programme runs from a conversion audit to user behaviour analysis, controlled tests and rollout. A change that fails its test does not go live.

Why choose them	Think twice if
The only agency here with a published price, from £1,000 a month; works across ecommerce, SaaS and lead generation	Smaller programmes start at that fee, so very small budgets may not fit

3. ALT Agency: In-House Builds

ALT Agency pairs CRO with WordPress and WooCommerce development at Eleven Brindley Place.

It studies analytics, heatmaps, session recordings and customer feedback, then designs, builds and deploys the changes itself, so tests are not stuck waiting for a developer.

Why choose them	Think twice if
Designs, builds and deploys changes in-house; runs CRO for both ecommerce and lead generation sites	Its site does not publish CRO case-study figures

4. Pure Marketing: Lead Generation

A Google Partner agency at Grosvenor House on St Paul’s Square, Pure Marketing treats CRO as diagnosis.

Heatmaps, session recordings, form analytics and funnel drop-offs point to the problems, then A/B and multivariate tests check the fixes. It works without long contracts.

Why choose them	Think twice if
No long contracts; form analytics and funnel data behind every test; free website review	Strongest on enquiry and lead sites rather than large online stores

5. Catalyst: B2B Funnels

Catalyst is a marketing agency at Assay Studios on Newhall Street, with offices in London and Dubai too.

Its CRO starts with a channel performance review across SEO, paid media, email and landing pages, then maps each touchpoint to where the buyer is in a B2B decision.

Why choose them	Think twice if
Looks at the whole funnel, from ads to sales enablement; offices in Birmingham, London and Dubai	CRO is one part of a wider marketing service rather than a standalone programme

6. Creative Ideaz: Small Firms

Working from 10 Brindleyplace, Creative Ideaz runs CRO alongside SEO, paid ads and websites, with sector pages for dental practices, trades, construction and clinics.

Its process covers heatmaps and recordings, user testing, A/B and multivariate tests, and form and speed fixes before rollout.

Why choose them	Think twice if
Sector pages for clinics, trades and construction; free conversion review	CRO sits inside a broad mix of services, so ask who leads it

7. Avid Panda: AI-Ready CRO

From Alpha Works in Alpha Tower, Avid Panda optimises sites for two kinds of visitor: people and the AI agents that may soon shop on their behalf.

Alongside usual conversion work, it checks that forms, buttons and checkout flows are structured so a bot can complete them, and it reports on agent form completions as well as human ones.

Why choose them	Think twice if
Optimises for AI agents as well as human visitors, with reports on both	Agent shopping is still early, so weigh how much of your traffic it affects

What CRO costs in Birmingham

Opace says its CRO starts from £1,000 per month for smaller programmes, rising with testing volume, traffic and funnel complexity. The other six quote after a first conversation.

• Use the free step. Get-Found runs a 13-point audit, and Pure Marketing, Creative Ideaz, Catalyst and Opace all offer a free review, audit or proposal.
• Check what the fee covers. Ask whether design and development of each test are included or billed separately.
• Ask about the contract. Pure Marketing works without long contracts; get the minimum term in writing from anyone else.
• Confirm VAT. Agency prices are usually quoted before VAT.

How long a test takes to call a winner

A test needs enough visitors to tell a real lift from chance. Get-Found’s rules show what a strict programme looks like.

• Set the bar first. It fixes 95% confidence and 80% statistical power before a test starts, so nobody moves the goalposts later.
• Expect weeks, not days. Most of its tests need between two and six weeks; busier sites finish sooner.
• Low traffic changes the plan. Pages with few conversions are better served by research-led fixes than long-running A/B tests.
• Ship winners properly. Coding a winning change into the site avoids leaving a testing script running for months.
