How much does a website cost in 2026?

Simple storefront €1,500-5,000, pro storefront with SEO €5,000-15,000, mid-size e-commerce €8,000-30,000, custom platform €30,000+. Beware of abnormally low quotes — hidden costs or insufficient quality to perform on Google.

How long does creation take?

Simple storefront 2-6 weeks, pro storefront 4-10 weeks, mid-size e-commerce 8-20 weeks, custom portal/SaaS 3-18 months. Beware of promises to deliver complex projects in days.

SEO included or added later?

Absolutely integrated from design. Architecture, URLs, topic silos, semantic markup and tech choices condition your ranking and are expensive to fix afterward. A site launched without native SEO often needs a partial rebuild after 6-12 months.

Is WordPress still a good option in 2026?

Viable for blogs and simple storefronts with autonomous management. But limited native Core Web Vitals performance, many plugins required. For maximum SEO/GEO performance: Next.js, Astro or TanStack Start offer better foundations.

Website creation 2026: what agencies don't tell you

Q: Which technology to choose?

Next.js (React with SSR) for any serious SEO/GEO project. WordPress for blogs and simple storefronts with autonomous management. Webflow for MVPs and landings. Decisive criterion: SSR compatibility.

Website creation: an opaque industry with inflated prices, underestimated timelines, and SEO missing by default. 75% of users judge a company's credibility based on its website, 88% don't return after a bad experience, and it takes 0.05 seconds to form a first visual impression. Here are the real French market prices, the tech that performs in 2026, and what an honest agency should tell you before you sign.

Real website prices in 2026

Tier 1 — Simple storefront: €1,500-5,000 (5-10 pages, WordPress/Webflow template, basic SEO). Tier 2 — Pro storefront: €5,000-15,000 (10-30 pages, custom design, integrated SEO, optimized Core Web Vitals). Tier 3 — Mid-size e-commerce: €8,000-30,000 (Shopify/WooCommerce, 50-500 products). Tier 4 — Custom portal/platform: €30,000+.

Hidden costs no one mentions

Hosting €10-500/month (cheap shared hosting kills Core Web Vitals), domain €10-30/year (register it yourself, never under the agency's name), maintenance €50-500/month, content (copy and visuals often not included), CRM/email/analytics integrations, and the rebuild in 3 years if the tech is obsolete.

Which technology to choose in 2026

WordPress: viable for blogs and simple storefronts with autonomous content management (43% of the web), but mediocre native performance and difficult GEO. Next.js / TanStack Start: native SSR, excellent Core Web Vitals, max scalability — recommended for any serious SEO/GEO project. Webflow / no-code: fast to deploy, ideal for MVPs and landings, but platform lock-in and GEO limits.

The decisive criterion: Server-Side Rendering

A tech without native SSR is a major handicap in 2026. AI crawlers (and partially Google) don't always execute JavaScript. A pure CSR React site risks not being indexed and won't be cited by AIs. SSR or static generation = absolute requirement.

Native SEO: in the brief, not as an option

The most common mistake: order a site, launch it, then call an SEO agency 6 months later. By then the architecture is wrong, URLs are poorly structured, and fixing it costs as much as rebuilding. SEO must be integrated from design: silo architecture, upstream keyword research, semantic markup in the template, 301 redirects mapped before launch, sitemap and robots.txt configured at launch.

Native GEO: the 2026 differentiator

A site launched in 2026 without GEO loses 30-40% of visibility from day 1. The 5 elements to integrate: 1) llms.txt at root; 2) Full Schema.org (Organization, Article, BreadcrumbList, FAQPage — 15+ types); 3) Open Graph and Twitter Cards on all pages; 4) AI crawlers allowed (GPTBot, PerplexityBot, ClaudeBot, Google-Extended); 5) SSR or static generation.

The 8 fatal mistakes

Strategy: launching without an SEO brief, letting the agency keep your domain, neglecting content (allocate 20-30% of the budget), choosing the tech 'the agency masters' instead of the right one. Technical: cheap shared hosting, no HTTPS, non-responsive site, uncompressed images (5MB unoptimized images kill Core Web Vitals).

Pre-launch checklist

HTTPS + valid SSL, 301 redirects if rebuild, XML sitemap submitted to Search Console, GA4 and Search Console connected, server response time < 200ms. Core Web Vitals: LCP < 2.5s, INP < 200ms, CLS < 0.1, WebP/AVIF images, lazy loading. SEO: unique title and meta, single H1, Open Graph, alt on images, clean URLs. GEO: accessible llms.txt, Schema.org Organization/Article/FAQPage, GPTBot/PerplexityBot/ClaudeBot allowed, SSR verified, ai-plugin.json.
