Website development standards in Europe

In Europe, alongside widely accepted global web standards, there are specific requirements for data protection, accessibility, and consumer rights.

Below are the main groups of standards we follow:

1. Legal and regulatory standards (critical for Europe)

These are the most important differences that make a site “European” from a legal standpoint:

1.1. GDPR (General Data Protection Regulation)

This is the core EU law on personal data protection. Any site that collects, processes, or stores data from users in the EU must comply.

This includes:

— A clear privacy policy: easy to find, understandable, and detailed information on what data is collected, how it is used, and how it is stored.

— User consent: active, informed consent for collecting and processing data (for example, via checkboxes — not pre-ticked boxes).

— Right of access, correction, and deletion: users must be able to request their data, correct it, or demand deletion (“right to be forgotten”).

— Data minimisation: collect only the data truly needed for the stated purpose.

1.2. ePrivacy Directive (Cookie Law)

This directive is closely linked to GDPR and governs cookies and other tracking technologies. It requires:

— Explicit consent before cookies: before setting any cookies (except those strictly necessary for the site to work), you must obtain user consent — usually via a banner or popup.

— Ability to refuse cookies: users must be able to decline non-essential cookies easily.

1.3. Web Accessibility Directive and WCAG

For the public sector in the EU and many large companies, site accessibility for people with disabilities is mandatory.

This is implemented according to international WCAG (Web Content Accessibility Guidelines) at AA or AAA level. A site should be:

— Perceivable: content available through different senses (for example, text alternatives for images).

— Operable: usable from the keyboard, with enough time to interact.

— Understandable: readable text and predictable navigation.

— Robust: compatible with assistive technologies (for example, screen readers).

1.4. Consumer rights directives (for e-commerce)

If the site is an online store, it must also meet EU consumer rights directives — clear display of prices, delivery terms, returns, and warranties.

2. Technical standards and best practices (universal but critical)

These standards are global, but strict adherence is the foundation for success in the European web space:

— W3C standards (HTML5, CSS3, JavaScript): we build sites using current versions of these languages, ensuring correct display in modern browsers, compatibility, and easier maintenance.

— Responsive design (mobile-first): the site should look and work well on any device — from large monitors to tablets and smartphones. We use a mobile-first approach, designing for phones first.

— Performance optimisation: loading speed is critical for user experience and SEO. We optimise images, minimise code, and use caching so the site loads as fast as possible.

— Security (SSL/HTTPS): SSL certificates (HTTPS) are mandatory. This protects user data, supports search visibility, and builds trust. We also take steps against common web vulnerabilities.

— SEO optimisation: while not uniquely “European”, quality SEO is key for visibility in EU search engines. This includes:

— Semantic HTML structure (correct use of H1–H6 headings).

— Optimised meta tags and descriptions.

— Clear URL addresses.

— Fast indexing and sitemap.

— Quality, relevant, unique content.

— Clear navigation and user experience (UX): the site should be intuitive, with a clear structure and a positive experience for the visitor.

3. Language considerations

— Multilingual support: for successful work in Europe, sites often need several languages — with correct technical implementation for SEO (hreflang tags) and convenient language switching for users.
