Sure! Survivorship bias is a cognitive bias where we tend to focus on the things or people that have survived a particular process or event, rather than on those that did not. In other words, we tend to overestimate the importance of certain factors in success, simply because we only look at those who have succeeded, and we ignore the role of chance or other external factors that may have contributed to success or failure. This bias can lead to flawed decision-making, as we may underestimate the risks or overestimate the opportunities of a particular situation based on incomplete or biased information.
Sure, here's a blog post about the survivorship bias:
Survivorship bias is a cognitive bias that can significantly affect conversion rate optimization strategies. This bias happens when you only consider the successful cases and ignore or overlook the failed attempts, leading you to arrive at an incomplete or inaccurate conclusion.
In conversion rate optimization, this bias can lead to wrong assumptions about what works and what doesn't. To understand this better, let's take a closer look at what survivorship bias is and how it can impact your approach to CRO.
Survivorship bias, also known as "survival bias," refers to the tendency to focus on the successes, rather than a full range of outcomes. This bias typically happens when you only look at data or examples from the people or things that survived an experience while ignoring the ones that didn't.
For example, you might only look at successful case studies or testimonials and ignore the ones that didn't work. Or, you might only analyze data from customers who completed a purchase and not the ones who abandoned their cart.
When you ignore the "non-survivors," you can develop a skewed understanding of what makes for success. This is because you're only seeing the variables that work, not the variables that didn't.
This kind of bias can be particularly problematic in conversion rate optimization, where every piece of information is essential to making informed decisions.
To illustrate the impact of survivorship bias on conversion rate optimization, here are some examples of how it can impact your strategies:
Testimonials can be a powerful tool for persuasion, but they can also be subject to survivorship bias. If you only use testimonials from customers who had an excellent experience with your product or service, you might be missing out on valuable feedback from the customers who didn't.
By ignoring negative feedback, you're missing out on opportunities to improve your product or service, which could lead to a higher conversion rate down the line.
A/B testing is a popular tool used in conversion rate optimization to test different versions of a page or element to see which one performs better. However, survivorship bias can creep in when you only test the versions that "survived" the testing process.
For example, suppose you're testing two different versions of your landing page. Version A performs better than Version B, and you decide to implement Version A on your website. But what if there were other versions that you didn't test that could have performed even better?
By only focusing on the successful test, you might miss out on valuable insights that could help you improve even further.
When analyzing your website's traffic sources, you might be tempted to only focus on the ones that generate the most traffic. However, this type of analysis can be subject to survivorship bias because you're only looking at the traffic sources that "survived" the competition.
For example, you might focus solely on social media traffic and ignore other traffic sources such as email marketing or paid advertising. By ignoring these other sources of traffic, you might be missing out on potential opportunities to improve your conversion rate.
Now that we've seen how survivorship bias can impact conversion rate optimization, let's look at some strategies to avoid it:
To avoid testimonial bias, collect both positive and negative feedback from your customers. By doing so, you'll get a more comprehensive understanding of the customer experience and identify areas for improvement in your products or services.
To avoid A/B testing bias, test more than two variations of your page or element. By doing so, you'll get a more comprehensive understanding of which elements work best and which don't.
To avoid traffic source bias, analyze all of your website's traffic sources, not just the ones that generate the most traffic. By doing so, you'll identify potential areas for improvement and opportunities to increase your conversion rate.
Survivorship bias can significantly impact conversion rate optimization strategies by leading to incomplete or inaccurate conclusions. To avoid this bias, it's essential to collect both positive and negative feedback, test more than two variations, and analyze all traffic sources.
By doing so, you'll get a better understanding of what works and what doesn't, leading to more informed decisions and a higher conversion rate in the long run.
