Introducing our 6-Step Conversion Research Framework

Did you know that most A/B testing programmes end up losing money, with teams quickly giving up? That’s because most CRO programmes don’t start with a robust conversion research process. We do. 

From day one, we identify the real problems your users are experiencing across your website. From then on, all valuable insights and problems are logged and turned into potential test ideas or to fix/implement immediately if it’s a no-brainer. 

Each test hypothesis is prioritised by impact, time to implement and whether tactics are delivered in-house, by a third party or by us and will continually develop as the process evolves. Recommendations can be anything from testing alternative landing page designs and using specific terminology to ways of fixing technical issues and developing the customer journey.

Finding bugs is usually the easiest way to have an instant impact on conversions. Once we are confident that the data is accurate and we are measuring everything we could possibly need, we then look for what's missing and what's problematic.

The output is a list of items to fix, which can be anything from uncompressed images, separate JavaScript/CSS script files that should be combined and slow page speeds to fundamental issues with the website.

Our analytics health check identifies leaks and drop-offs across the website, identifies key segments (such as actions that correlate with higher conversions), and understands what users are doing and not doing. This stage also helps with prioritising issues.

Using heatmaps, scroll maps and user session replays, we find underperforming pages, usability and clarity issues, and points of friction and distractions.

We help you set up customer surveys, web traffic polls and user interviews to understand buyer groups, what problems they are trying to solve, how they're deciding, what’s holding them back, what else they want to know and any sources of friction. We also pay attention to the language they use to describe their problems, challenges and solutions.

This is a structured way to evaluate pages (segmented by device category, as mobile and desktop are totally different contexts) where we assess key pages across popular journeys to identify areas of interest, such as:

• Relevancy - does it meet expectations? Does the message match the original ad?

• Clarity - is it easy to understand what is going on?

• Motivation - is it increasing motivation to take action?

• Sources of friction - what is being done to minimise friction and distractions on the page?

Plan and run face-to-face and/or online user tests to identify usability and clarity issues and sources of friction. This instant feedback reveals what’s difficult to understand, difficult to do and what goes wrong.

CRO stands for Conversion Rate Optimisation. In digital marketing, we typically spend a lot of time and resources on attracting visitors to your website. However, an effective CRO programme can lead to business growth by consistently converting more of the visitors you already have.

This scientific approach to marketing places your customers and their needs centre stage, and through a process of rigorous testing, learning and adapting you’ll continuously improve the efficiency of your website and increase revenue.

But it’s more than just maximising conversion rate. It’s about improving the customer journey from start to finish and optimising your business. When developing test ideas, we are looking to increase revenue, as well as:

• Improve relevancy
• Simplify the process
• Reduce friction
• Increase motivation
• Dilute distractions
• Reduce hesitancy
• Provide clarity
• Give more emphasis to commercial pages

Where we have the most traffic? No.

We test where we have the highest dropoff and plug that leak. It's best to start with the biggest problems to solve.

It depends. The two things you need to account for are a) if you are testing different KPIs (conversion rate of email sign-up vs conversion rate of purchases) or b) if the traffic is not overlapping (testing the landing page for Google Ads traffic and also testing the checkout page).

When you have two tests that overlap, both tests get the credit, and things get murky. You don’t want to run multiple tests on the same pages (instead, you should combine these changes into the same test so that you can attribute them appropriately). If you have enough traffic, you can do multi-variant testing to see the interaction between those changes.

There are cases where you can run multiple tests simultaneously if you are testing completely different pages/sections. You'll need to think about how much interaction will there be between the tests? For example, the interaction between testing the navigation and product image sizes is minimal.

If mobile and desktop have enough traffic to run separate tests, then do it as it can be a totally different experience. You can also segment the results but it’s easier to treat them as different tests.

Even if we know what the right problem is, we never know what the right solution is, which is why we test. The more variations we can test, the better. However, this is also based on how much traffic we have.

You never want to run an A/A test over an A/B test. This advice usually comes from bloggers who never actually do testing. Instead of just an A/A test, you can run an A/A test at the same time as other tests. Or an A/A/B 25%/25%/50% test. Don’t sacrifice precious testing time on A/A testing.

An A/B test is a 50%/50% traffic split. Bandit testing changes traffic allocation algorithmically depending on what is winning. The point of bandit testing is that you are maximising the amount of money you are making but it takes longer to learn which variation is better.

We typically recommend you run Bandit Tests if you have a one-week sale/limited campaign (flash sales, Christmas, Black Friday), although we won't be able to reuse the learnings anywhere or reach a scientific conclusion, we'll be confident that during the campaign you'll make the most amount of money that you can.

Whenever you change something during the test, reset the test data.
