Advanced metrics that every ecommerce app should measure
Today, more than 63% of online purchases in Spain are made from mobile devices, and apps far outperform browsers in terms of conversion, retention and recurrence. But why does this happen, and what happens in the user's brain that leads them to buy more from an app? In recent years, neuroscience applied to mobile ecommerce has revealed answers that help to understand digital consumer behavior and optimize an eCommerce app to sell more.
In this article you will discover the brain factors that drive mobile shopping and how to apply them to your app. In addition, we will analyze how Duuo Shop, the vegan sneakers store, has taken advantage of the psychology of the mobile user to increase sales and loyalty thanks to its eCommerce app.
Apps generate an instant reward environment that triggers the release of dopamine, the neurotransmitter associated with pleasure and quick decision-making. According to a Stanford University study, users react 45% faster to visual stimuli when interacting with touch interfaces than when browsing the web.
Apps allow for less friction, more speed and fewer interruptions. All of this fuels impulsive behavior that favors purchase.
This set of factors accelerates the purchase decision, especially in low-medium ticket products.
Behavior within an app is not rational: it is influenced by brain biases that can boost conversion when designed strategically.
When an experience is easy, the brain interprets it as correct. According to Nielsen Norman Group, cognitive fluency can increase purchase confidence by as much as 23%.
Phrases such as "Last units" or "Delivery in 24h" activate the amygdala, which drives quick decisions. Baymard Institute indicates that this bias increases conversions by 8% to 19%.
Animations, micro-interactions or confirmation messages activate the reward circuit, which improves satisfaction and retention.
Neuroscience has shown that user attention increases when the brain receives clear, organized visual stimuli with well-defined hierarchies. Native apps optimize this environment better than mobile websites.
According to a study by App Annie, users spend 78% more time in apps than in mobile browsers. This is due to:
The apps allow the integration of colors, animations and smooth transitions that activate brain regions associated with emotion and memory, favoring the purchase decision.
Personalization activates the "familiarity effect," which the brain interprets as trust and confidence. According to McKinsey, companies that apply advanced personalization generate 40% more revenue from their digital channels.
The app thus becomes an "assistant" capable of anticipating the user.
Duuo Shop, a Spanish brand of vegan sneakers, is a clear example of how scientific principles applied to mobile ecommerce directly impact conversion.
These adjustments, based on neuroscience applied to mobile ecommerce, generate more engagement and greater emotional response from the user.
Apps that apply neuroscientific principles can increase sales between 20% and 50% according to data from AppsFlyer and studies by UX Research Lab.
It is the use of brain and behavioral studies to optimize eCommerce apps. It helps to improve conversion, decision speed, retention and impulse purchases.
Immediacy, cognitive fluency, personalization, visual excitement and tactile reinforcement are key elements influencing the decision.
Applying micro-interactions, simplifying processes, reinforcing actions, personalizing content and optimizing loading times.
Because it generates less friction, more emotional stimuli, tactile experiences and greater sustained attention, which drives action.
Conversion, recurrence, time per screen, clicks per step, abandonment, response to notifications and average order value.
Science shows that the brain responds best to fast, simple, personalized and emotionally stimulating experiences: just what mobile apps offer. Understanding these principles and applying them strategically allows you to create a more effective eCommerce app, closer to the user and much more profitable. Neuroscience applied to mobile ecommerce is not a trend: it is the way forward for brands that want to lead the future of digital commerce.
