By Endless Gain


Endless Gain Psychologist Professor Ben Ambridge talks about 12 ways to overcome people’s cognitive biases for better conversions.

If you’re looking to optimise your website through experimentation, you should focus on developing your designs and sales/marketing techniques based on consumer psychology and behavioural economics.


Because you are selling to humans who think and feel and react and respond, and there are ways to overcome their psychological biases to improve your conversions.

Overcoming or applying these consumer biases through your optimisation strategies may help you improve your customers’ buying experience on your site and ultimately your sales.
