Web trend reports look similar: lists of micro-animations, giant typography, pastel gradients. These visual inventories overlook the technical and regulatory constraints that have truly changed the way websites are designed in 2024. Here, we offer an overview focused on structural changes, those that weigh on choices of architecture, stack, and compliance.
Structured markup and multimodal search: the real SEO lever of 2024
Search engines no longer just index plain text. In 2024, search interfaces have strengthened the role of synthetic and multimodal answers. Poorly marked content, without schema.org, and without a coherent Hn hierarchy, loses visibility against systems that automatically extract and summarize information.

We observe that structured markup now conditions discoverability much more than the choice of a font or a gradient. Websites that have invested in structured data (FAQ, HowTo, Product, Article) capture an increasing share of clicks in position zero.
This evolution requires cross-functional work between writing, front-end development, and technical SEO. Successful web design in 2024 is no longer judged solely on the screen: it is judged by the quality of what machines read in the code. To keep up with the news on Only Internet, this technical dimension is part of the topics regularly addressed.

European Accessibility Act: interface compliance becomes a legal obligation
The European Accessibility Act comes into effect on June 28, 2025. The entire year of 2024 has served as a period for early compliance for those who did not want to find themselves out of law at the last minute.
Concretely, this affects keyboard navigation, color contrasts, compatibility with screen readers, and the semantic structuring of pages. Purely aesthetic web trends in 2024 (complex animations, unconventional menus, scroll hijacking) come into direct tension with these requirements.
What compliance changes in daily design
- Interactive components (modals, carousels, accordions) must be operable via keyboard with a visible focus, which limits certain decorative animations
- Minimum contrast ratios impose more restricted palette choices, reducing the leeway on very desaturated color trends
- Forms require explicit labels and associated error messages via ARIA attributes, not just by color or icon
Teams that treat accessibility as a peripheral constraint accumulate technical debt. Those that integrate it from the design stage produce more robust interfaces and, as a side effect, faster ones.
Digital sobriety and web performance: beyond the discourse
The average weight of pages has continued to increase despite discussions on sobriety. The tension between visual richness and performance remains the main friction point in 2024. Websites that load several megabytes of unoptimized scripts and media penalize the user experience on mobile and increase their carbon footprint.
We recommend treating performance as a design criterion, not as a post-delivery fix. Native lazy loading, modern image formats (AVIF, WebP), reduction of third-party JavaScript: these technical choices have more impact on visitor satisfaction than a change in graphic trend.
Concrete indicators to monitor
The Core Web Vitals remain the benchmark for measuring perceived experience quality. Largest Contentful Paint, Interaction to Next Paint, and Cumulative Layout Shift constitute the triptych that Google uses to evaluate a page’s performance.
A site that scores well on these three metrics offers a measurable user experience, independent of aesthetic trends. This is a sustainable competitive advantage.
End of third-party cookies and first-party collection: the web changes model
The gradual disappearance of third-party cookies has restructured the product priorities of web teams in 2024. The issue goes beyond simple GDPR compliance: it changes the way user journeys, conversion funnels, and measurement strategies are designed.
First-party data collection becomes the foundation of any digital strategy. Websites must offer interactions that encourage users to voluntarily share their data (accounts, preferences, segmented newsletters) rather than relying on opaque tracking.
Consequences for interface design
Consent banners are no longer sufficient. UX teams are rethinking collection points to ensure they provide perceived value to the visitor: real personalization, exclusive content, exclusive features. A registration form placed without clear compensation generates rejection.
Advertising targeting is evolving towards contextual methods and anonymized cohorts. Front-end developers must integrate these new SDKs and consent measurement tags without degrading page performance.
Web trends 2024: what really matters in a redesign project
Visual trends (expressive typography, micro-interactions, gradients) remain tools serving design. They do not constitute a strategy in themselves. A redesigned site in 2024 that ignores structured markup, regulatory accessibility, measured performance, and first-party collection accumulates concrete risks.
Technical architecture choices weigh more heavily than aesthetic choices on the lifespan and profitability of a site. Animations and trendy graphic elements become outdated in a few months. A solid, compliant, and high-performing technical foundation remains usable for several years.
Web design in 2024 is read as much in the source code as on the screen. Teams that understand this deliver sites that users, engines, and regulators treat correctly, without constant renegotiation.
