What we do

What Convertica does as your CRO agency

A CRO agency works on what happens after visitors arrive. Convertica's work comes in three fixed steps, from finding the problems to building every fix on your site.

Find the problems

Free CRO audit

Eight checks on your page, for people and for AI agents, each scored out of 100. The report gives every finding, with its evidence and how to fix it. Run the free CRO audit.

Fix one page

One page rebuild

One page. Convertica's team builds every fix the audit found on it, on your site, whatever platform it runs on. $497.

Fix the whole site

Full site rebuild

Every page on your site. Each one is audited and Convertica's team builds every fix the audits found, on your site, whatever platform it runs on. $1,997.

Two readers

AI agent readiness

Agent readiness is one of the eight checks: whether AI shopping agents and AI search can read your products, prices and policies. A rebuild covers those fixes with the rest.

How it works

How working with Convertica's CRO agency works

From a free audit to every fix live. You decide after the audit whether to go on, and the audit app runs the rest: setup, your order online, approvals and a new score at the end.

  1. Run the free CRO audit

    Enter your website and watch the audit check your page for people and for AI agents. Your free report shows your score and every issue it found, with how to fix each one.

  2. Choose to fix every issue

    Your report ends with the number of issues found and a choice: fix this page or your whole site. One page costs $497 and the whole site $1,997, both paid through Stripe Checkout.

  3. Set up and sign online

    Five short steps: what the page is for and who approves changes, access to your site by invite (never a password), anything off limits, how changes are approved, then sign your order.

  4. Follow every fix

    Convertica's team builds every fix the audit found, on your site, whatever platform it runs on. Your job page shows each fix, and changes to your words or offers wait for your OK.

  5. See your new score

    When every fix is live and checked, the page is audited again and you get the before and after scores by email.

Most rebuilds take a couple of days, 7 days at most from the day we have access to your site.

What is a CRO agency?

A CRO agency, or conversion rate optimization agency, is a company that specializes in raising the share of website visitors who take a desired action, such as buying, signing up or getting in touch. Unlike a general marketing agency, it does not bring more traffic. It works on what happens after visitors arrive, using research and A/B tests to decide what to change. You will also see it called a CRO marketing agency or a digital CRO agency; the work is the same.

What does a CRO agency do?

A CRO agency checks your tracking, researches where and why visitors leave, ranks the fixes, designs and builds tests, reads the results and helps roll out what wins. A traditional agency supplies the whole team for this:

  • A strategist, who sets goals with you and decides what gets tested next.
  • A researcher or analyst, who checks the tracking, studies the funnel and the recordings, and reads test results. Our guide to CRO analysis walks through the method.
  • A designer, who turns each hypothesis into a variation.
  • A developer, who builds the variation and checks it works on every browser and device. The types of test are compared in our guide to CRO testing.

Some agencies also build the winning changes into your site. Others hand them back to your developers.

What does an ecommerce CRO agency do?

An ecommerce CRO agency does the same work for an online store, where most sales are won or lost on product pages, the cart and checkout, and where AI shopping agents may now read the catalog. Convertica's store work includes the JustThrive and dScryb case studies; the ecommerce conversion optimization guide covers the fixes that matter most for a store.

CRO agency, CRO company or CRO consultancy?

The names overlap, and people search for all three. In practice, a CRO agency or CRO company usually sells a done-for-you team, while a CRO consultancy diagnoses, prioritizes and directs, and your own people build. Convertica works as a CRO agency with fixed prices: an audit that says what to change, and rebuilds in which its team builds it. In medicine, a "CRO company" is a contract research organization that runs clinical trials, which has nothing to do with websites.

Should you hire a CRO agency or build an in-house team?

Hire a CRO agency when no one in your business can design, code and launch a change, or when you want results before you hire. Build an in-house team when you have the traffic to test all year and the budget for several specialists. Our guide to the CRO specialist role lists the skills to check, and the CRO consultant guide covers the middle option.

How to choose a CRO agency

To choose between CRO agencies, compare how each one checks your data, decides what to test, builds and checks the tests, calls a winner and hands over what it learned. The questions below work for any agency, Convertica included. Good answers are specific; vague ones are a warning.

Questions to ask a CRO agency

  1. Who will work on our site, and who builds the tests? Check that the senior person in the sales call is involved after it, and whether designers and developers are in-house or outsourced.
  2. How will you check our tracking before you start? If they do not plan to, their findings rest on numbers nobody has verified.
  3. Can we see a real audit or test plan you have delivered? Look for evidence behind each recommendation, not a list of best practices.
  4. What do you measure a win by? Revenue, orders or qualified leads. Button clicks alone are not a result.
  5. How do you decide a test is finished? They should talk about sample size and significance, set before the test starts. The A/B test sample size calculator shows what your traffic allows.
  6. Who owns the testing account, the data and the designs? If you part ways, you should keep the history of what was tested and what won.
  7. How do winning tests get built into the site? A test that wins inside a testing tool is not the same as a permanent change. Ask who does that work.
  8. What does it cost, and what exactly is included? If the answer needs a sales call, ask why. Convertica publishes its pricing up front.

Red flags when hiring a CRO agency

  • A guaranteed lift quoted before anyone has seen your analytics.
  • Winners declared after a few days, or tests stopped as soon as one version pulls ahead.
  • Results without a metric, timeframe or source. A percentage with no context cannot be checked.
  • A best-practice checklist sold as research. Advice that would be the same for any site is not about yours.
  • No losing tests, ever. Every honest testing program has plenty.
  • Lock-in. A long contract before any research, or a testing account and data you cannot take with you.

Convertica publishes each case study result with its metric, timeframe and source, so you can apply the same standard to it.

CRO agency FAQ

What is a conversion rate optimization agency?

A conversion rate optimization agency, or CRO agency, is a company that specializes in raising the share of website visitors who take a desired action, such as buying, signing up or getting in touch. It works on what happens after visitors arrive, using research and A/B tests to decide what to change.

What does a CRO agency do?

A CRO agency checks your tracking, researches how visitors use the site, turns what it finds into ranked hypotheses, designs and builds A/B tests, reads the results and helps roll out the winners. Some agencies do all of it. Others do the research and direction while your team builds the changes.

Why hire a CRO agency?

Hire a CRO agency to turn more of the traffic you already pay for into customers, without building a team first. An agency brings the research, design and development skills a test program needs. Convertica starts with a free CRO audit, so you can see what it finds before you spend anything.

Should I hire a CRO agency or build an in-house team?

Hire a CRO agency when no one in your business can design, code and launch a change, or when you want results before you hire. Build an in-house team when you have the traffic to test all year and the budget for several specialists.

How do I choose a CRO agency?

Choose a CRO agency by asking who builds and checks the tests, how they verify your tracking, what they count as a win, how they decide a test is finished, who owns the testing account and data, and how winners get built into the site. Avoid any agency that guarantees a percentage lift before seeing your data.

How much do CRO agencies charge?

Convertica's prices are fixed: the CRO audit is free and a one page rebuild costs $497 and a full site rebuild $1,997. Other agencies price CRO in different ways, such as per month, per project or per test, so ask each one exactly what is included.

What does an ecommerce CRO agency do?

An ecommerce CRO agency raises the share of an online store's visitors who buy. It checks the tracking against real orders, studies where shoppers leave, and fixes or tests the pages that lose them, mostly product pages, the cart and checkout. Convertica does this with a free CRO audit and fixed-price rebuilds.

Can a CRO agency work alongside my own team?

Yes. With Convertica, the free audit gives every finding with how to fix it, so your own team can build the fixes. If you would rather not, a rebuild has Convertica's team build them on your site, whatever platform it runs on.

What is the difference between a CRO agency and a CRO consultant?

A CRO agency supplies a team that does the work. A CRO consultant directs the work your own team does. Convertica's standard offers are a free CRO audit and two fixed-price rebuilds in which its team builds the fixes. A retainer or ongoing consulting is available on some bespoke campaigns.

Is a CRO agency the same as a contract research organization?

No. In marketing, a CRO agency is a conversion rate optimization provider that helps websites turn more visitors into customers. In medicine and pharmaceuticals, CRO stands for contract research organization, a company that runs clinical trials.
