With a growing number of users accustomed to accessing websites via mobile devices, and Google's earlier announcement of implementing a "mobile-first indexing" strategy, many websites are now designed following the "mobile-first" principle.
But have you considered that serious usability issues might arise when these "mobile-first"
web designs are displayed on PC desktops?
What potential usability issues can arise from adhering to a "mobile-first" web design?

Arachne Group Limited indicates that while
responsive design allows websites to intelligently adapt their layout based on user behavior and the device environment, content originally optimized for small screens can encounter issues like fragmented content and excessive white space when "forcibly" displayed on the large screens of PC desktops.
When significant portions of the page suffer from content fragmentation, the overall user experience can be severely impacted, leading to:
— Increased page length requiring more user scrolling.
— Utilization of mobile-specific design elements (e.g., accordion panels), making it difficult for users to locate needed information.
— Enlarged images and increased white space potentially separating related content across different screen areas, forcing users to remember information located on different sections and scroll back and forth to draw conclusions or make decisions.
— Increased page length and working memory demands due to content fragmentation; scattered information also makes it harder for users to evaluate content and construct a conceptual mental model of the information presented on the site.
— Websites with fragmented content can diminish the prominence of important information, leading some users to perceive the company as hiding details, potentially eroding trust in the brand.
That being said, "mobile-first" web design is not without merits. For instance, reducing content per screen can enhance text prominence, indirectly improving the overall website experience.
What web design strategies can help us reduce the usability problems brought by "mobile-first"?

As an increasing share of web traffic originates from mobile devices, it is imperative for businesses to prioritize the
"mobile-first" web design principle. Therefore, during the
website development process, we must pay attention to the following aspects to avoid the most common pitfalls:
Prioritize Key ContentTo ensure the website renders correctly across different devices, it is advisable to prioritize the display of important content. Use visual styles like larger fonts, contrasting colors, etc., compared to other elements, to highlight this content, thereby enhancing the page's sense of hierarchy and aesthetics.
Avoid Overly Complex OperationsThe relatively small screens of mobile devices often necessitate multiple steps or actions for users to access target information or functions. However, for PC users, multiple steps or actions only increase cognitive load and cause frustration. Therefore, strive to minimize unnecessary operations in the design and place crucial content within the immediately visible area of the page.
Utilize White Space JudiciouslyIn web design, excessive white space can make a page appear empty and monotonous, while insufficient white space can make the interface look cramped and lack "breathing room." Paying attention to controlling the white space between elements helps create a more balanced and aesthetically pleasing page, while also highlighting the hierarchical relationship of the information presented.
Avoid Mobile-Specific Interactions and Design ElementsDuring the web design process, besides ensuring users can find information quickly and reducing their cognitive load, we should also consider factors like screen size and user experience on PC devices. Try to avoid using mobile-specific interactions and design elements, such as hamburger menus or accordion panels, to prevent increasing the operational difficulty of the website on PC devices.
Provide Clear Feedback and PromptsOffering clear feedback and prompts at appropriate times, and using easily understandable vocabulary and icons to represent page elements and functions, can help users quickly comprehend the page information, functionalities, operational methods, and outcomes. This reduces users' cognitive load and helps them build an accurate conceptual model.
【Summary】While designing an entire website following the "mobile-first" principle can indeed lead to usability issues on PC devices, these problems can be avoided. It is recommended not only to evaluate how the website renders on different devices and screen sizes but also to conduct A/B testing to select the most suitable web design solution.
