Online presence relies on a technical foundation that shifts every year. In 2024, three structural changes redefine how a site gains visibility: the replacement of a key performance indicator by Google, the emergence of AI-generated answers in search results, and a heightened accessibility requirement driven by new standards. Understanding these mechanisms allows for adjustments to a web strategy before it becomes obsolete.
Interaction to Next Paint: the new Core Web Vital that changes optimization
Since March 2024, Google has replaced First Input Delay (FID) with a new indicator called Interaction to Next Paint (INP). The difference is significant: FID only measured responsiveness to the very first click of a user, while INP assesses the site’s responsiveness across all interactions, from the first tap to the last.
In practical terms, a site could achieve a good FID score with a fast-loading page at first contact, but then become slow as the visitor navigated through a dropdown menu or filled out a form. INP penalizes this type of degradation.
For web development teams, this shifts the optimization work. It is no longer enough to focus solely on initial loading. Every JavaScript event handler, every animation triggered by a click, every layout recalculation after a user action is now part of the calculation. Sites relying on heavy client-side frameworks are the most exposed, as their scripts often block the main browser thread during interactions.
Several technical avenues can improve an INP score: breaking long JavaScript tasks into micro-tasks, deferring the loading of non-visible components, and reducing DOM complexity so that the browser can recalculate display faster after each action. Resources published on the Journal du Webmaster website regularly detail this type of technical optimization for developers and site managers.
Google AI Overviews: adapting your SEO strategy to generated answers
Google rolled out its AI Overviews in the United States in May 2024, then expanded them to over 100 countries in October 2024. By March 2025, nine European countries had access, and the rollout reached over 200 countries and territories in more than 40 languages by May 2025.
The principle: for certain queries, Google displays an AI-generated summary above the traditional organic results. This block captures the user’s attention even before they see the traditional blue links.
What this changes for organic visibility
Organic traffic is redistributed towards the sources cited by AI. Content that is not structured to be understood and extracted by a language model loses visibility, even if it ranks well on the traditional results page.
- Structure content with direct and factual answers in the first paragraphs of each section, as AI Overviews favor excerpts that directly address the query.
- Use clear semantic markup (H2, H3, lists, tables) so that indexing robots can quickly identify the hierarchy of information.
- Produce content that provides verifiable expertise, as Google has indicated that E-E-A-T signals (experience, expertise, authority, trustworthiness) remain crucial in selecting sources for its AI responses.
The challenge is no longer just to rank on the first page, but to be the source that AI chooses to cite.
Web accessibility and WCAG 2.2: a standard ahead of regulations
The W3C has published the WCAG 2.2 standard, which adds new criteria compared to version 2.1. Notable additions include a minimum clickable area size for touch interfaces and strengthened requirements for accessible authentication (reducing reliance on cognitive tests like complex CAPTCHAs).
A gap persists between best practices and legal obligations. U.S. public regulations continue to reference WCAG 2.1 level AA as the standard, and compliance deadlines have even been postponed by a year to April 2026. This gap creates a gray area where a legally compliant site may still fall below recommended technical standards.
Why integrate accessibility into your web strategy despite this gap
An accessible site improves the experience for all users, not just those with disabilities. Buttons that are large enough benefit anyone navigating on a smartphone screen in bright sunlight. Correct color contrasts reduce visual fatigue for all visitors.
From an SEO perspective, a site with clean markup, properly described images, and keyboard-navigable links sends quality signals that search engines value. Accessibility and SEO share a common technical foundation: code clarity and content readability.
Content and search in 2024: what distinguishes a visible site from an ignored one
The three previous trends converge towards the same conclusion: the technical quality of the site now conditions the reach of the content. A well-written article hosted on a slow, inaccessible, or poorly structured site loses visibility compared to equivalent content published on a technically flawless platform.
The content strategy itself is evolving. Regular publishing is not enough if each page does not address a specific search intent. Generalist content that skims a topic without providing actionable answers is what AI Overviews ignore first.
Three criteria separate content that attracts traffic from content that stagnates:
- Specificity: addressing a precise angle with data or concrete examples rather than covering a broad topic without depth.
- Technical freshness: updating outdated information, particularly references to tools or standards that have changed.
- Exploitable structure: a reader (human or machine) must be able to extract the answer to their question by scanning the subtitles and the first words of each paragraph.
The transition of INP to Core Web Vital, the global expansion of AI Overviews, and the shift towards WCAG 2.2 outline a web where technical rigor and content relevance are no longer options. A site that ignores these three axes in 2024 accumulates a technical debt whose effects on its visibility are measured in months, not years.
