A high-performing website loads quickly, responds to visitor interactions without delay, and remains accessible across all devices. Creating a website involves more than choosing a tool or template: it requires technical decisions that affect the project’s search rankings, conversions, and regulatory compliance.
Interaction to Next Paint: the performance metric most websites overlook
A page’s initial load speed is no longer enough to determine whether a website performs well. Since March 2024, Google has replaced FID (First Input Delay) with INP (Interaction to Next Paint) in its Core Web Vitals.
The difference is significant. FID measured responsiveness only during a visitor’s first interaction. INP evaluates how quickly a page responds throughout the entire visit, with every click, keystroke, and menu opening.
In practice, a site can have a good load time yet still score poorly on INP if its JavaScript blocks the browser’s main thread after the initial render. Pages with lots of animations, dynamic forms, or carousels are most at risk. To learn about the technical improvements available when designing a web project, see the Geekovision website.
Monitoring INP during development using the measurement tools built into browsers helps avoid having to restructure code after launch.
Web accessibility: a regulatory requirement for some e-commerce websites
Digital accessibility has taken on a new legal status. Since June 28, 2025, the European Accessibility Act has applied to several categories of private services, including e-commerce and certain banking, transport, and telecommunications services.
Not all brochure websites are automatically covered. Some microenterprises are exempt. However, any site offering an online purchasing journey falls within the scope of the legislation.
Checks focus on the purchasing journey itself, not just the appearance of the pages. A checkout button that cannot be accessed by keyboard, a form field without a label that a screen reader can read, or a visual CAPTCHA with no alternative can each make a site non-compliant.
Priority checks
- Every form field must have an explicit label that assistive technologies can read
- The entire site must be navigable using only a keyboard, without requiring a mouse
- Text and background color contrast must meet the WCAG thresholds to ensure readability
- Error and confirmation messages must be conveyed to screen readers, not indicated solely by a color change
Accessibility also affects organic search rankings: clean semantic markup, text alternatives for images, and a consistent heading structure benefit search engines as well as users with disabilities.
Cookie consent: an interface that determines a site’s compliance
Cookie management involves more than displaying a banner. Consent must be obtained before any trackers that require it are activated. Rejecting must be as easy as accepting, and visitors must be able to change or withdraw their choice at any time.
In practice, a banner with a large “Accept” button and a discreet “Settings” link hidden in a submenu does not meet these requirements. Both options must be equally visible and require the same number of clicks.
This interface requirement directly affects a company’s online presence. A site with a non-compliant cookie banner risks penalties, but also loses the trust of visitors who are increasingly attentive to how their data is handled.
Page structure and SEO: what makes the difference
A website’s organic search performance depends on technical foundations that design alone cannot make up for. Three elements determine how well a search engine can index and rank a site’s pages.
Heading hierarchy and internal linking
Each page should follow a strict heading hierarchy (one H1, followed by H2s and H3s) that reflects the logical structure of the content. Search engines use this hierarchy to understand the main topic and the subtopics covered.
Internal linking—the links between pages on a site—distributes authority and guides crawlers. If a site’s deeper pages receive no internal links, those pages are likely to be under-indexed.
Content and semantic relevance
SEO-friendly content is about more than repeating a keyword. Expanding the semantic field helps search engines understand the topic: for a page about website creation, terms such as “domain,” “hosting,” “design,” “user experience,” “pages,” and “customers” strengthen semantic relevance without resorting to keyword stuffing.
The density of a primary keyword should stay below a reasonable threshold. Beyond that, content becomes less readable, and search engines may penalize it.
Mobile performance and indexing
Mobile-first indexing means Google uses a site’s mobile version as its primary reference for rankings. A site that cuts off content, hides links, or places elements too close together on mobile will lose visibility in search results.
- Test every page with Google’s mobile-friendly testing tool before publishing
- Make sure buttons and links have a sufficiently large tap target
- Ensure that the content visible on mobile is the same as on the desktop version
A website that incorporates these criteria during the design phase, rather than addressing them after launch, saves time and protects its budget. Regulatory compliance (accessibility and cookies), responsiveness measured by INP, and rigorous semantic markup provide the technical foundation on which a company’s online presence can be built for the long term.
