New-generation websites

Tomorrow’s website is run by talking to AI

We now build our websites in Astro, a technology that produces ultra-fast static pages, with no database to hack and almost no hosting costs. That is already the case for 7days.dev and for the websites in our editorial network, which score 100 in all four Lighthouse categories.

And the back office is disappearing. Tomorrow, you will no longer go through an admin interface to change a text, add a product or launch a promotion. You will ask your AI assistant, in writing or out loud, and your website will update itself. That is already how we develop our own websites.

  • SpeedPages served in a few milliseconds, 100 on Lighthouse, mobile and desktop.
  • SecurityNo database and no plugins to update, so almost nothing to attack.
  • CostAlmost free hosting and no theme or plugin licences.
  • AIPages that are crystal clear for Google and AI, and a website you develop by talking to AI.
You ask your AI assistant, out loud, to add the autumn collection to the home page. The AI replies that it is done, and the website updates itself without going through a back office.

The choice of technology depends on your business, your objectives and your budget. We master the main technologies and advise you objectively. We always put your long-term interest ahead of a solution that suits us.

Our recommendation

Astro, our choice for new-generation websites

Who is it for? Showcase websites, content websites, blogs, networks of websites and local pages, and more and more online shops (with Shopify behind the scenes for payment).

  • Maximum speed, static pages served in a few milliseconds
  • Security, no database and no vulnerable plugins
  • Almost free hosting and no licences
  • Clean code, ideal for SEO, GEO and AI agents
  • A website run by talking to AI, with no back office
  • No traditional admin interface, changes go through AI or through us
  • Less suited to websites that rely on many WordPress plugins
WordPress, total flexibility

Who is it for? Showcase websites, blogs, e-commerce (WooCommerce), custom platforms, start-ups that want total control

Advantages:

  • Maximum flexibility, with more than 60,000 plugins available
  • Excellent native SEO (when configured properly)
  • Full ownership of your data and code
  • Controlled hosting costs (from €5/month)
  • A huge global community (support, developers, resources)

Limits:

  • Requires regular maintenance (WordPress updates, plugins, security)
  • A moderate learning curve for advanced administration
  • Security needs watching (a target for hackers because it is so widespread)

Our technical recommendations:

  • An optimised premium theme (Kadence, GeneratePress, Astra)
  • Essential plugins only (< 15 to limit conflicts)
  • Optimised WordPress hosting (OVH, Kinsta, WP Engine, O2Switch)

Total budget (excluding build): €150 to €500/year (hosting + theme + premium plugins)

Shopify, turnkey e-commerce

Who is it for? Pure online shops, dropshipping, e-commerce brands that want to focus on product and marketing, not on technical matters

Advantages:

  • All-in-one hosting, zero technical maintenance
  • Performance and security handled by Shopify
  • Powerful e-commerce apps (basket reminders, upselling, customer reviews)
  • Built-in payments (Shopify Payments) with no transaction fees
  • Automatic scalability (easily handles more than 10,000 orders a month)

Shopify costs and constraints:

  • Fixed monthly costs, €29 to €79/month (depending on the plan)
  • Transaction fees if you do not use Shopify Payments
  • Limited customisation compared with WordPress (less flexible for custom work)
  • Decent SEO, but less configurable than a CMS such as WordPress
  • Total dependence on the Shopify ecosystem (migration is more complex if you change solution)

Our technical recommendations:

  • Shopify plan at €79/month minimum (the €29 Basic plan is too limited for professional use)
  • A conversion-optimised theme (free Dawn, or a premium theme at €180 to €350 depending on needs)
  • Essential apps, customer reviews, basket reminders, SEO, email marketing (+€50 to +€200/month depending on volumes and features)

Total budget, €80 to €300/month, or €950 to €3,600/year depending on the plan + the apps used.

Webflow, premium design without compromise

Who is it for? Upmarket brands, creative agencies, tech start-ups, businesses that want a unique, modern design without limits

Advantages:

  • Completely free design with no template constraints
  • Advanced native animations and interactions (scroll, hover, transitions)
  • Clean, lightweight code (better performance than the average WordPress site)
  • An intuitive visual CMS for the end client
  • Ultra-fast hosting included (global AWS CDN)

Limits:

  • Higher costs ($23 to $212/month depending on traffic)
  • Limited e-commerce (max. 3,000 SKUs, basic features vs Shopify)
  • Fewer plugins/extensions than WordPress
  • A designer’s learning curve (Webflow skills needed for advanced changes)

Our technical recommendations:

  • CMS plan minimum ($23/month) for dynamic websites
  • Avoid Webflow e-commerce for > 500 products (choose Shopify)
  • Perfect for premium showcase websites, portfolios and landing pages

Total budget (excluding build): $280 to $2,500/year depending on traffic

Our advice:

  • You want a unique, modern design without compromise → Webflow
  • You want flexibility + control + powerful SEO → WordPress
  • You are launching an online shop with no technical skills → Shopify
Headless CMS — advanced technical flexibility

Who is it for? Complex web/mobile applications, multichannel websites (web + app + IoT), projects requiring extensive API integrations, advanced technical teams

What is a headless CMS? A complete separation between the back end (content management) and the front end (display). The content is stored in a database accessible through an API, then consumed by any interface (website, mobile app, interactive kiosk, voice assistant).

Main solutions:

  • Strapi (open source, self-hosted, very flexible)
  • Sanity (real-time, excellent for collaborative content)
  • Contentful (premium SaaS, enterprise scalability)
  • Ghost (geared towards blogging/newsletters, simple and efficient)

Advantages:

  • A modern decoupled architecture (independent back end + front end)
  • Maximum performance (an optimised front end with no CMS constraints)
  • Native multichannel, the same content delivered on web, mobile app, smartwatch, etc.
  • Complete freedom on the front end (React, Vue, Next.js, Nuxt, Svelte…)
  • Stronger security (no direct database access from the front end)

Limits:

  • High technical complexity (experienced developers needed)
  • Higher development costs (custom architecture)
  • Separate front-end + back-end maintenance
  • A steep learning curve for teams
  • A less extensive plugin ecosystem than WordPress

Total budget (excluding build): €500 to €3,000/year depending on the solution (self-hosted Strapi = cheaper, Contentful Enterprise = very expensive)

Our advice: Reserved for projects with a real need for multichannel delivery, or a technical team able to maintain the architecture. Otherwise, WordPress/Shopify/Webflow are more than enough.

Framer / Siter / Typedream — the new design-first + AI wave

Who is it for? Tech start-ups, creative agencies, solo entrepreneurs, projects that need fast iteration and premium design without a developer

What is it? A new generation of ultra-modern no-code/low-code tools that combine intuitive visual design + generative AI + technical performance to create professional websites in a few hours (compared with several weeks traditionally).

Main solutions:

Framer (the current leader)

  • Ultra-modern design with smooth native animations
  • Built-in AI for content generation and translation
  • A simple but effective CMS
  • Excellent performance (loading time < 1.5 s)
  • Ideal for landing pages, premium showcase websites, portfolios, SaaS marketing

Siter (the French challenger)

  • 100% no-code, an intuitive Figma-style interface
  • Modern templates and automatic responsiveness
  • Decent native SEO (tags, sitemap, basic structured data)
  • Very competitive prices (free for up to 3 projects)
  • Ideal for very small businesses and SMEs, tight-budget projects, fast MVPs

Typedream (specialising in content creators)

  • Ultra-simple (a Notion-like interface)
  • Conversion-optimised landing pages and sales pages
  • Native marketing integrations (email, payment, analytics)
  • Ideal for content creators, info-preneurs, product landing pages

Advantages:

  • Extremely fast creation (a complete website in 2-5 days vs 4-8 weeks)
  • Modern design and native animations (Webflow level without the complexity)
  • Built-in AI for content, translation and SEO optimisation
  • Affordable prices (€15 to €50/month depending on the platform)
  • Frequent updates and new features
  • Ultra-fast hosting included (global CDN)

Limits:

  • A young ecosystem (fewer plugins/integrations than WordPress)
  • Limited e-commerce (not for shops > 50 products)
  • Total dependence on the platform (migration is difficult)
  • Good SEO, but less configurable than a traditional CMS
  • Community and resources still limited compared with WordPress
  • Less suited to complex projects (advanced members’ area, marketplace)

Total budget (excluding build): €180 to €600/year depending on the platform and traffic

Our recommendation:

  • Framer if you want the best possible design + modern animations (budget €25-50/month)
  • Siter if your budget is tight and you need a professional showcase website quickly (free → €20/month)
  • Typedream for a product/service landing page or the creator economy (€15/month)

When to avoid these solutions:

  • Online shop > 50 products → Shopify is a must
  • Complex website with custom features → WordPress/headless
  • Need for total control over advanced SEO → WordPress
  • A project that must last 10+ years without platform dependence → self-hosted WordPress

The choice depends on 4 decisive factors. Here is our final advice:

  1. Your budget (initial + recurring annual)
  2. Your need for future flexibility (changes planned within 2-3 years)
  3. Your in-house technical skills (maintenance autonomy)
  4. Your launch deadline (urgent or planned)

Website and e-commerce website redesign agency

Why redesign or build a new website in 2026?

Is your website 3, 5 or 10 years old?

Your website is your first salesperson. It works 24/7, answers questions, reassures your prospects and generates sales. But only if it is well designed.

It may have worked well at launch, but today your performance is stagnating. Here are the signs that it is time to move to a more modern, higher-performing version.

Performance

Your website is slow

After a few seconds of waiting, a large share of mobile visitors leave before they have seen your offer. And Google measures that slowness.

Design

It looks dated

Design is the first impression. An ageing website makes people doubt how serious you are before they have even read anything.

SEO

It is invisible on Google

A badly structured website stays hard to find, and every visit then has to be paid for in advertising.

Conversions

It generates few enquiries

Visitors, but few contacts? The journey does not lead people to take action.

Maintenance

It is hard to change

Going through a developer to change a photo costs time and money. A new-generation website can be edited by talking to AI.

GEO

AI does not recommend it

Google AI Mode, Gemini and ChatGPT cite fast, clear, well-structured websites. A confusing website gets left out.

Website design or redesign project audit

Describe your project in a few lines to get an initial assessment of its feasibility, its stakes and its growth potential.

  • Analysis of your objectives and constraints
  • Identification of functional and technical needs
  • Recommendation of suitable solutions (CMS, structure, stack)
  • Estimate of the resources and the project scope

The aim is to secure decisions upstream, avoid common mistakes and lay a consistent foundation for the rest of the project.

A badly designed website is expensive, lost traffic, missed conversions, total dependence on paid advertising. Conversely, a well-designed website becomes an asset that generates qualified traffic, converts your visitors and lowers your acquisition costs.

We do not build “pretty websites”, we build conversion machines, optimised for Google and generative AI. At Oli-via-net, every website is designed around 3 fundamental pillars, technical performance, commercial effectiveness and scalability.

Pillar 1: Technical performance

Loading time < 2 seconds

  • Advanced optimisation, compressed WebP images
  • Lazy loading, minified code
  • CDN, smart caching
  • Premium hosting if needed

Technical SEO built in from day one

  • A structure designed for Google, semantic HTML5 markup
  • Schema.org structured data, XML sitemap, optimised robots.txt
  • Core Web Vitals in the green

Natively mobile-first Designed first for mobile (60% of your traffic), then adapted for desktop — not the other way round.

Security & compliance

  • HTTPS as standard
  • Automatic daily backups
  • Intrusion protection
  • Native GDPR compliance (cookie banner, privacy policy)
Pillar 2: Commercial effectiveness

Strategic calls to action Visible buttons, short forms (5 fields max.), persuasive messages, reassuring micro-interactions.

Persuasive, benefit-focused content Texts written to convince, not just to inform. Customer-focused copywriting, “What you gain” > “What we do”.

Pillar 3: Scalability & autonomy

A modular, scalable architecture. New features are easy to add, blog, shop, members’ area, online booking, multilingual

Guaranteed maintenance and responsive support. Regular updates (WordPress, plugins, security), automatic backups, responsive technical support

Our 4-step methodology

A well-designed website is a measurable growth engine.
Our technical and UX redesigns help you gain speed, rankings and conversions, while reducing advertising costs.

Every project follows a 4-step structured process to guarantee quality, meet deadlines and stay aligned with your business objectives. You are involved at every key step, with regular approvals.

A web page mock-up with its blocks.

Step 1: Audit, strategy and design

Analysis of your ecosystem:

  • Audit of the current website (if redesigning), SEO, technical, UX, conversions
  • Competitor benchmark (5 competitors analysed)
  • Definition of measurable business objectives (leads, sales, awareness)

Visual design:

  • Choice of a suitable template or desktop and mobile mock-ups of every page (depending on the project and budget)
  • Brand guidelines if needed (colours, typefaces, iconography)
  • Approval at each step (3 approval points)

Deliverables:

  • Complete approved site structure + wireframes of the key pages
  • Reasoned choice of platform (Astro, WordPress, Shopify, Webflow…)
  • Complete approved design, ready for development
Code chevrons, the development of the website.

Step 2: Development & technical optimisation

Technical development:

  • Integration of the mock-ups or adaptation of the template
  • Platform set-up (Astro, WordPress, Shopify, Webflow)
  • Technical SEO optimisation (tags, Schema.org, sitemap)

Performance & analytics:

  • Speed optimisation (WebP images, cache, CDN if needed)
  • GA4 + Google Tag Manager set-up
  • Configuration of conversions and key events

Conversion optimisation:

  • Reassurance elements (testimonials, logos, certifications)
  • Strategic CTAs (buttons, forms, optimised journeys)
A content page under an SEO magnifying glass.

Step 3: Content & SEO

  • Optimisation or writing of the texts (depending on the package)
  • Integration of texts, images and videos on every page
  • Unique, persuasive title tags and meta descriptions

If redesigning:

  • 301 redirects to preserve rankings
  • Checking there is no traffic loss after migration
  • During the redesign, we protect your current rankings by keeping the good URLs and restoring the important inbound and outbound links, to avoid any loss of visibility.
A screen validated with a tick, the website going live.

Step 4: Testing, training & launch

Exhaustive testing:

  • Multi-browser and multi-device
  • Checks on forms, features and tracking
  • Accessibility validation (WCAG 2.1)

Training & launch:

  • Personalised training (2 to 6 hours depending on the package)
  • Complete documentation + video tutorials
  • Move to production + HTTPS certificate
  • 1 month of priority support + review at D+30

Too many websites go live without an SEO and GEO strategy.

The result is zero organic traffic, total dependence on paid advertising and a wasted investment. SEO is not an option you add afterwards, it is the very foundation of the architecture.

Our approach: SEO is built in from the design stage.

SEO architecture — the invisible foundation

A structure in thematic silos Content organised logically by theme to strengthen semantic authority

An optimised site structure A maximum of 3 clicks to reach any page from the home page (the 3-click rule)

Strategic internal linking Internal links designed to pass “SEO juice” to the priority pages

Clean, descriptive URLs example.com/services/search-engine-optimisation (≠ example.com/page?id=1234)

Breadcrumb trail Secondary navigation that helps Google and users understand the structure

Technical SEO — invisible but critical foundations

Optimised meta tags. Unique title tags (50-60 characters), persuasive meta descriptions (150-160 characters), a clear heading hierarchy

Schema.org structured data. JSON-LD markup for Google rich results, FAQ, products, reviews, events, breadcrumb, organisation.

Automatic XML sitemap. Automatic generation and submission to Google Search Console.

Optimised robots.txt file. Precise control of Google’s crawl (pages to index/exclude).

Canonical tags. Avoids internal duplicate content.

Clean 301 redirects. If redesigning, all the old URLs redirect to the new ones (zero traffic loss).

Core Web Vitals performance — modern technical SEO

LCP (Largest Contentful Paint) < 2.5 s The loading time of the largest visible element — a direct impact on Google rankings.

INP (Interaction to Next Paint) < 200 ms How quickly the website responds to user interactions.

CLS (Cumulative Layout Shift) < 0.1 Visual stability (no content shifting during loading).

Technical optimisations deployed:

  • Compressed WebP images + lazy loading
  • Minified and deferred CSS/JS code
  • Browser and server caching configured
  • CDN (Content Delivery Network) for global delivery
  • Optimised premium hosting (SSD server, PHP 8+, HTTP/2)

Our goal, 100 on PageSpeed Insights, mobile and desktop

Optimised content — editorial SEO

Strategic keyword research. Identifying high-potential queries (volume + intent + difficulty).

Content that matches search intent. Every page precisely answers the search intent (informational, navigational, transactional).

Semantic optimisation. A richer vocabulary, natural co-occurrences, synonyms, frequently asked questions.

Catchy headings and H tags. A unique, descriptive H1, with H2-H6 structuring the content logically.

Persuasive meta descriptions. A hook that makes people want to click in Google’s results.

Frequently asked questions about website design & redesign

Building or redesigning a website is a strategic investment. Between the choice of technology, timescales, costs and expected results, it is normal to have questions before getting started. This FAQ answers the most frequently asked questions about building and redesigning websites — WordPress, Shopify, Webflow — to help you make the right decisions, avoid costly mistakes and maximise the return on investment of your project.

Prices and budget

How much does it cost to build a website?

At Oli-via-net, a showcase website starts at €600 excl. VAT and an e-commerce website at €900 excl. VAT. Websites for franchise networks and large corporations are quoted on request. The final price depends on the number of pages, the content to produce and the features.

Why do prices vary so much from one agency to another?

They depend on the time spent, the degree of customisation, the content to write and the technology. Our prices come from a highly tooled method, with proven templates and AI for repetitive tasks. The standards, however, stay the same, SEO, GEO and performance included.

What costs should you plan for after launch?

The domain name, hosting, any subscriptions (Shopify, for example) and maintenance. An Astro website costs very little to host and has no theme or plugin to renew.

Technology

What is an Astro website?

Astro is a technology that generates static pages, ready to be served. The website is very fast, very secure because it has no database, and almost free to host. It is our choice for new-generation websites.

Astro, WordPress, Shopify or Webflow, which should you choose?

Astro for a fast, secure website run with AI. WordPress if you want a traditional back office and plenty of plugins. Shopify for turnkey e-commerce. Webflow for complete design freedom. We advise you according to your business and your budget, not according to our habits.

Will I be able to edit my website myself?

Yes. On WordPress, from the back office. On an Astro website, by asking an AI assistant for the changes, in writing or out loud, or by leaving them to us.

Will it soon be possible to manage your website by talking to AI?

It is already largely possible. We develop our own websites by talking to AI, and this way of working will gradually replace admin interfaces, including for running an online shop.

Timescales and method

How long does it take to build a website?

A few weeks for a showcase website, longer for an e-commerce website or a network of websites. The timescale depends mainly on how quickly the content and approvals are available.

Does a redesign make you lose your rankings?

No, if it is well managed. We keep the good URLs, redirect the old ones to the new ones, keep the important links and monitor traffic in Search Console after launch.

How does a website creation project work?

In four steps, audit and strategy, development and technical optimisation, content and SEO, then testing, handover and launch. You approve each key step.

SEO and AI

What is a GEO-optimised website?

It is a website that AI, Google AI Mode, Gemini or ChatGPT, can easily understand and cite. Fast pages, clear content that answers real questions, structured data and consistent information across your whole online presence.

Will my website rank well on Google?

SEO is built in from the design stage, architecture, technical work, content and structured data. No one can guarantee a position on Google, but a well-built website starts with a head start.

Why is website speed so important?

A slow website drives visitors away, converts less and weighs on your rankings. Our goal is 100 on PageSpeed Insights, on mobile and on desktop.

Franchises and large corporations

Do you build websites for franchise networks?

Yes. We design a national website with a useful local page for each outlet, a consistent brand across the whole network and harmonised Google profiles, so that each franchisee is visible in their town.

Do you work with large corporations?

Yes. For groups and large companies, we take into account multi-site architecture, multilingual requirements, integration with the information system, accessibility, security and governance. The project is scoped and quoted separately.

Do you have a project in mind, a website to improve, or simply questions about the best strategy to adopt?

We help businesses across France – from Paris to Perpignan – grow their visibility, attract more prospects and win more customers through their website.

Our aim is to turn your website into a genuine growth lever, measurable and profitable.
