Mobile first is a concept in web design in which the development of websites and web applications is primarily geared towards the needs of mobile devices. This means that the website or application is first designed and developed for use on mobile devices, such as smartphones and tablets, before it is optimised for desktop computers or laptops.

The importance of mobile first in neuroweb design lies in the fact that more and more users are accessing the internet via mobile devices, such as smartphones and tablets. A study by Statista from 2021 shows that around 55 per cent of web traffic worldwide comes from mobile devices. To ensure a positive user experience on mobile devices, websites and applications must be optimised specifically for the smaller screens and touch interactions of mobile devices.

Mobile first not only means that a website or application should look and function well on mobile devices, but that it should also be quick and easy to load. This is particularly important as the loading time of a website also has an impact on the user experience and user behaviour. A slow website can cause users to bounce and switch to the competition.

In neuroweb design, mobile first can help to improve the user experience on mobile devices and increase conversions. An optimised mobile website can help users stay on the website longer and perform more interactions, such as filling out forms or adding products to the shopping cart.
