What changes when we rebuild

Three illustrative patterns we see across industries — not specific client case studies. Run your own audit to see exactly what we'd change about your site.

Before
Built 2016
  • Not mobile responsive
  • No schema markup
  • Slow page load
  • Generic stock photos
After SOSEI

  • Mobile-first responsive

  • Self-hosted fonts, no Google CDN
  • AI-discoverable via llms.txt
SEO · GEO · AEO

Found by Google, quoted by AI

Three jobs, one site. SEO gets you ranked. GEO gets you crawled by ChatGPT, Claude, Perplexity, and Google AI. AEO gets you quoted when they answer — because the site that's cited wins the customer.

SEO

Classical search

Clean titles, meta, canonicals, sitemap.xml, heading hierarchy — everything Google ranked you for in 2015 still ships by default.

GEO

Generative Engine Optimization

Makes your site findable and attributable by AI crawlers: GPTBot, ClaudeBot, PerplexityBot, Google-Extended, Applebot-Extended. Named in robots.txt. llms.txt steering file. Organization + WebSite JSON-LD.

AEO

Answer Engine Optimization

Makes your content quotable. FAQPage, HowTo, BreadcrumbList, QAPage schemas. Declarative H1s, front-loaded answer blocks, short citable sentences — the exact shape ChatGPT, Perplexity, and Google AI Overviews lift verbatim.

Voice

Voice assistants

Speakable JSON-LD tells Siri, Google Assistant, and Alexa which sentence to read aloud when someone asks about you in the kitchen or the car.

Structured

Full schema.org coverage

Organization, LocalBusiness, Service, FAQPage, HowTo, BreadcrumbList, Article, WebPage — emitted automatically based on what each page actually does.

Analyzer

Separate GEO and AEO scores

Our free audit reports SEO, GEO, and AEO as three distinct scores — not bundled. You see exactly which engines can find you and which can quote you.

The subscription advantage

A one-time redesign ages in 18 months.

Standards, algorithms, regulations, AI crawlers — something new every few months. SOSEI tracks them in the generation pipeline, so each time you regenerate, the new build ships against the current web.

2024

Google AI Overviews rolled out

Schema-poor sites started losing visibility in AI answers

2024

llms.txt proposed for AI crawlers

Sites with one get cleaner attribution from ChatGPT, Claude, Perplexity

2025

EU Accessibility Act enforceable (28 June)

Non-WCAG public-facing sites in scope; penalties set by each member state

Ongoing

New AI crawlers, schemas, Core Web Vitals updates

Every regen ships against the current standards we track

One subscription. Re-generate whenever the rules change.

New schema, new AI crawler, new accessibility rule — we update the pipeline; you hit regenerate (up to 5×/domain) or refine with the chat editor. No agency call, no “we need to redesign again.”

A modern website without the slow redesign process

SOSEI handles the rebuild, hosting, privacy basics, search structure, and future updates in one subscription.

Your Brand, Modernized

We keep your logo, colors, and tone recognizable, then rebuild the design so it feels current, credible, and easier to trust.

Key Pages Rebuilt

SOSEI crawls your most important pages, brings over useful content and images, and turns them into a cleaner multi-page website.

Edit With Chat

Ask for a new headline, section, image, service page, or tone change in plain language instead of waiting on a developer for every small edit.

Versions You Can Restore

Preview changes before they go live, keep older versions, and roll back if a rewrite or redesign does not feel right.

Mobile-First Experience

Built for the device most visitors actually use first, with clear sections, readable text, and fast pages on phones.

SEO + AI Search Ready

Clean headings, metadata, schema, FAQs, and AI-readable structure help search engines and AI assistants understand what your business offers.

Analytics Preserved

Common tools like GA, GTM, Meta Pixel, Hotjar, LinkedIn, TikTok, Plausible, Umami, and Clarity can be detected and kept behind consent.

GDPR-Ready Foundation

Cookie consent, privacy pages, legal templates, and self-hosted fonts give your site a stronger privacy baseline from day one.

Legal Pages Included

Privacy, terms, cookies, impressum, accessibility, and 404 pages can be generated in your site language and adjusted later.

Accessibility Basics Built In

Semantic HTML, readable contrast, keyboard navigation, and screen-reader friendly structure are handled in the renderer, not left to chance.

SSL + Custom Domain

Go live on HTTPS and connect your own domain or subdomain with common DNS providers such as Zone.ee, GoDaddy, and Namecheap.

Privacy-Friendly Fonts

Fonts are served from SOSEI instead of third-party font CDNs, improving privacy and reducing unnecessary external requests.

Contact Form Built In

Every site can include a contact form, with submissions saved in your dashboard so new leads are easier to manage.

Any Language

Estonian stays Estonian. English stays English. The generated copy and legal pages match your source language.

Built to Convert

Industry-specific sections, clearer calls to action, social proof, and shorter forms help visitors understand your offer and take the next step.

How It Works

Six steps from outdated URL to live, modern, AI-citable site.

Step 01

Submit Your Website

Share your current website URL. Our system begins a comprehensive analysis of your entire online presence.

Works with any website platform — WordPress, Wix, Squarespace, custom HTML, or any other.
Step 02

AI Crawls Your Site

A parallel crawler walks up to 15 of your top pages, extracting content, images (with dimensions), brand colors, fonts, logo, favicon, and your tracking codes (GA, GTM, Meta Pixel, Hotjar, LinkedIn, TikTok, Plausible, Umami, Clarity).

Your logo also gets a Claude vision pass to lift 2–3 dominant brand hexes — so the rebuild's palette comes from your actual brand, not a guess.
Step 03

Assets Re-hosted

Every image, the logo, and the favicon are downloaded from your old site and uploaded to SOSEI storage.

Your new site doesn't hotlink the old one — when you eventually take the old domain down, nothing breaks.
Step 04

AI Plans, Designs, and Writes

A 5-stage pipeline runs: industry detection across 161 verticals → site plan → frozen voice card → design system (tokens, mood, motion) → 10-way parallel page writing → legal pages.

The LLM never writes HTML or CSS — it produces structured JSON that our renderer compiles. That keeps WCAG contrast, layout, and motion contracts unbreakable. Choose Fast (Sonnet 4.6, ~1 min) or Best (Opus 4.8, ~3 min).
Step 05

Compliance Baked In

WCAG 2.1 AA contrast (AAA on body text), cookie consent banner, six auto-generated legal pages (privacy, terms, cookies, impressum, accessibility, 404), and sitemap.xml + robots.txt that names 18 AI crawlers + llms.txt.

Self-hosted fonts only — no Google Fonts, no third-party request fires before consent. Tracking scripts preserved from your old site, gated behind consent.
Step 06

Review, Edit, Go Live

Preview the rebuild, refine it with the chat editor (sections, header, footer, brand colors, fonts, or generate new images), then point your domain.

You get a live SOSEI URL the moment generation finishes. For your own domain, the dashboard shows the exact DNS records to add — CNAME for subdomains, or A records / CNAME flattening / ALIAS for apex. We handle the Let's Encrypt cert via Cloudflare for SaaS.
First rebuild:~1 min Fast · ~3 min Best.Re-generate anytime.

Why not an agency? Why not DIY?

Traditional agencies cost $5,000+ and take months. DIY tools make you the developer, designer, SEO specialist, and lawyer. We do all of it, for a subscription price.

How it's engineered

Not another AI website builder

SOSEI takes your existing URL and rebuilds it — preserving brand, content, and tracking — through a 5-stage AI pipeline that grounds every decision in a curated catalog, then compiles the output through a renderer that the LLM can't bypass.

AI-native pipeline
Built on a purpose-built, frontier-AI pipeline — not a WordPress theme wrapper
161 industries
Catalog-grounded design and copy — not generic AI website-builder output
Source-language native
Estonian source → Estonian site. No machine-translated awkwardness
Renderer-enforced quality
WCAG contrast, motion, layout contracts can't be violated mid-edit

“Most outdated sites carry the same five problems — no schema, no llms.txt, no consent gating, fonts hotlinked from Google, images hotlinked from the old CMS. SOSEI encodes all of them as renderer-enforced defaults, so a regen can't ship without them.”
