Adapt or Die – Your CRO Strategy is The Key To Survival
4.8 (96%) 5 votes

In the struggle for survival, one factor improves your chances more than any other. Being able to adapt gives you a huge advantage when competing in a changing environment, and a test-and-learn approach makes you more resilient when new challenges arise. That’s why evolution is the ultimate CRO strategy.

Conversion Rate Optimisation (increasing the proportion of customers to visitors) is an important marketing activity for digital businesses. The average conversion rate for eCommerce websites is 2-5%. In a recent study,’s Conversion Rate was found to be 13%. The result? In 2018, Amazon’s share of the US eCommerce market was 49%, and it accounted for 5% of all retail spending nationally.

Ecologists might describe Amazon as an “apex predator.” Personally, I see them more as a “keystone species” (one which shapes the ecosystem in which it lives). Either way, this commercial success story owes a lot to the CRO strategy implemented by the company’s founder, Jeff Bezos. 

Bezos’ focus on two key themes has defined Amazon since its launch over twenty years ago. Those themes were outlined in his 1997 letter to the company’s shareholders. First, he summed up his business outlook: “It’s all about the Long Term.” Then, he described what would now be called his CRO strategy: “Obsess over Customers.” 

Perhaps the most revealing part of Bezos’ letter, however, was a line from the first paragraph. Even in 1997, adaptation was at the forefront of his mind: 

The competitive landscape has continued to evolve at a fast pace…Our goal is to move quickly to solidify and extend our current position while we begin to pursue the online commerce opportunities in other areas.

CRO strategies have been around since the Conversion Rate metric was first incorporated into marketing glossaries. However, with the development of new technologies for measuring Conversion Rate, optimization has become a central part of digital marketing.

An endless stream of experts have offered definitive advice on how to “boost conversions”. The truth is, they have all been wrong.

Think about it, if a business operates in a changing environment, telling them how to adapt misses the point…

  • What works for one company might not work for another (a polar bear with stripes)
  • Some adaptations do not fit every company (a pigeon with a peacock’s tail)
  • As soon as the environment changes, the adaptation will be useless (RIP the woolly mammoth) 

Here are some of the CRO strategies that experts have sworn by in the past…

  • Shortening the Funnel: Reducing the number of steps a customer has to complete before converting seems like an intuitive strategy. At every stage of the conversion funnel you lose customers, so why not shorten the funnel? Well, it turns out there are good reasons for keeping your funnel intact. Leads often need nurturing before they convert. You need time to build up exposure and frame your product correctly. 
  • Building a labyrinth: Casinos are built to keep people inside. In the bad old days, companies offered Freemium trials with hidden opt-out clauses. Even now, exit pop-ups and re-marketing strategies can go too far and harm sales. These approaches will only provide a short-term increase in sales. The minor increase is certain to be followed by a breakdown in trust, damage to your brand’s reputation, and a vastly reduced CLV. 
  • Pressuring the sale: High-pressure sales techniques (in which time constraints, unlikely discounts and hyperbolic messaging are used to shape the consumer’s decision making process) are almost always more trouble than they’re worth. Consumers often experience psychological reactance when they feel pressured into a purchase, and reducing a customer’s options can lead to a powerful aversion effect.

As mentioned earlier, telling someone how to adapt is not helpful. Instead, encouraging them to adapt, and to keep on adapting, is the best way to equip them for the future.

A continuous process of experiment and change (known as a “test-and-learn” or “iterative” process) is the best way to ensure survival. That is why the ultimate CRO strategy is evolution.

This section outlines the iterative process that makes up a successful conversion rate optimization (CRO) strategy. At every stage, it is important to consider:

  • User Experience (UX) 
  • Your customers’ Psychology
  • Customer Retention and Lifetime Value (CLV)
  • Your Value Proposition and goals

The Iterative Process: A Proven CRO Strategy

conversion rate optimization methodology

1. Data Analysis

Data Analysis involves quantitative and qualitative methods. 

The quantitative approach will require you to interrogate your analytics and funnel data, to see where visitors enter and leave the conversion process.

The qualitative approach involves understanding how people use, experience and interpret your store. This requires a selection of specialist CRO tools

Studying Consumer Behaviour is essential to understanding data

We like to think of ourselves as being rational when making decisions. In fact, this is very rarely the case. We are predisposed to certain perceptual biases that skew our judgement and inform our decisions.

Cognitive biases assume many forms, such as Social Proof (following the crowd), Confirmatory Biases (where your response to evidence is shaped by prior beliefs) and Framing (where expectations influence your perceptions).

Thinking about how people make decisions will help you to optimise your conversion funnel. 

2. Creating Your Hypothesis

Your hypothesis is a theory about how users experience your site, and how you might improve it.

For example, you might hypothesise that changing the number of products on your homepage will increase the number of people who click on one. Alternatively, you might think about changing the copy, images or CTAs.

3. Design

How do you incorporate a hypothesis into your website? The design stage is where you begin to create an alternative to your current site. Once you have your hypothesis in one hand, and your new design in another, you can start testing.

4. Testing

To start testing, you need a hypothesis, a treatment, and a goal.

The easiest way to do this is to set up A/B tests. These work by testing a variant page against a control. If your control is your current page (“A”) – then “B” is the newly developed alternative. Testing platforms will usually assign traffic randomly (at 50:50) to each page, and the page that garners the highest conversion rate is the winner.

However, A/B testing requires a certain level of traffic and a degree of technical knowledge. An alternative is to simply observe the effect that regular small changes have on your KPIs.

5. Optimization

If your A/B test fails, you should examine the data, work out which aspects failed, and determine why. 

If your A/B test wins … you still need to examine the data. This will allow you to determine whether the test was statistically significant and why the variant worked better than the control.

If you decided not to run an A/B test, you should wait until you have enough evidence to justify implementing or discarding your changes. Consider using follow-up surveys to ask customers about their experiences.

In all cases, the important thing is to keep testing once you have found a winning variant.

Why Evolution is the Ultimate CRO Strategy

In order to keep your Conversion Rate as high as possible and survive as an eCommerce business, constant improvements in your website and communications are necessary. The most successful businesses advocate a “culture of optimization,” in which every department is expected to continuously tweak and optimise. This iterative strategy may be the difference between achieving long-term success and going the way of the Dodo…

The iterative process, built into a broader “culture of optimization,” is the best way to keep your conversion rate high. The occasional design innovation (like the spontaneous mutations that introduce new factors into the equation) is still an important investment. However, constant adaptation will ensure your tail continues to dazzle and your web keeps catching flies…
