Website & online store # A website the AI can actually name Updated: 27 August 2026 Short answer We build custom websites and online stores with complete structured data, machine-readable content mirrors, **llms.txt** and a citable structure built in **from the first line of code** — not added later as an SEO package. The same team that runs our GEO/AEO programs builds the site, so design and AI visibility are produced in one build. Fixed-price quote, the source code is yours, the first conversation is free. ## Why can't this be bolted on afterwards? Because half of it doesn't work that way. Structured data is only reliable when it is **generated from the same source as the visible content** — otherwise the page shows one price and the search engine receives another, which is exactly what gets penalised. The same goes for machine-readable mirrors and update dates: if a human maintains them, sooner or later they will lie. And there is a harsher point: if content **only appears after JavaScript runs**, most AI crawlers never see it. This is where a lot of expensive, modern websites fail — beautiful to a visitor, empty to a model. That is not a setting but an architecture decision, and it can only be fixed by rebuilding. That is why the same hands do the build and the visibility. Not because it's convenient, but because they are the same job. ## What exactly does aiseo42 build? - **Custom websites** — marketing and service pages that bring enquiries from both search and AI answers, designed for conversion. - **Custom online stores** — with their own product data model (variants, minimum order quantities, per-customer pricing), custom ordering logic, payment and invoicing integration, and product structured data. - **Rebuilds of existing sites** — when the current system is what blocks visibility; content and search rankings are carried over with redirects. ## What is included as standard, at no extra cost? ### Complete structured data Not from a template, but generated from the page's actual content — so it cannot drift away from it. Organisation, service, product, article, FAQ: search engines and language models receive, in machine-readable form, what you sell and at what price. ### Machine-readable content mirror Every page has a clean, markup-free text version at the same path, declared in the HTML head. A language model gets the substance in a single request, with nothing to misread. ### llms.txt and a full content dump A concise list of facts and pages with dates, plus the entire content in one file. Those few kilobytes are the cheapest way to let a model process your whole site cleanly. ### A citable structure Every page opens with a self-contained summary, headings are the questions people actually ask, and numbers carry a source and a date. Models lift content at paragraph level — this is the shape they can lift. ### Server-rendered output Content is real text in the HTML, not something that appears after JavaScript runs. Whatever only the browser assembles is invisible to most AI crawlers — this is where most expensive modern sites fail. ### A permissive robots.txt GPTBot, OAI-SearchBot, ChatGPT-User, PerplexityBot, ClaudeBot, Google-Extended, Applebot, CCBot and the rest, allowed by name. What isn't allowed in cannot cite you. ### Speed, measured Content-hashed, indefinitely cacheable assets, self-hosted fonts, zero third-party trackers on the critical path. Handover ends with a measurement report, so there is something to compare against six months later. ### Protected forms Several server-side layers stacked on top of each other: origin check, honeypot field, size limit, human verification, IP rate limiting — and the enquiry is stored safely before any email goes out. ## How does the process work? - 01 ### Conversation You tell us what your company does, who your customers are, and what they ask an AI before they buy. If it turns out you don't need a new site, only visibility, we say so here. - 02 ### Plan and quote Written scope, fixed price, fixed deadline. The site structure is designed around search and AI intent from the start — we don't optimise afterwards. - 03 ### Build You see it working every two weeks, not as a screenshot. Design and machine readability are produced in the same build. - 04 ### Handover and measurement The source code and every access credential are yours. Measurement report, indexation, structured data error list — and from then on we watch whether the models actually reach your content. ## Do you need a new site, or just visibility? A new site is not always the right answer, and we say so in the first conversation. Roughly, the decision looks like this: | | Your situation | What we recommend | Your site is sound, fast and readable — you're just not being cited | GEO/AEO program, no new site | The site is slow, plugin-heavy, content appears after JavaScript | Rebuild, then a visibility program | The company is launching, there is no site yet | New build — visibility included | Your ordering process doesn't fit a template system | Custom online store | You have a site nobody has touched in years | Start with the free check, then decide ## How do you know aiseo42 can do this? You don't have to take our word for it. This website was built with the exact method we sell: open [aiseo42.com/llms.txt](https://aiseo42.com/llms.txt) and you see precisely what a language model receives about us. The same equipment goes into every client site. aiseo42 comes out of the same workshop as the RootCR development brand, and its live client systems — with measured numbers, the measurement method and the date — are published there: [rootcr.com/case-studies](https://rootcr.com/case-studies/). The full technical breakdown of what [AI findability as standard equipment](https://rootcr.com/ai-search-visibility/) means is there too. ## Frequently asked questions How much does a website or online store cost? Price follows scope: how many page types are built, how much custom logic there is, how many external systems have to be connected. We quote per client, with a fixed price and a fixed deadline — the first conversation and the AI visibility check are free. How is this different from a normal web studio? With us AI visibility is not a package you can buy afterwards; it is part of the build. Structured data is only reliable when it is generated from the same source as the visible content; a machine-readable mirror and an update date are only true when the system writes them, not a human. You cannot bolt that on — you can only build it in. I already have a site. Do I need a new one? Not necessarily. If your site is fundamentally sound and only visibility needs work, a GEO/AEO program is the cheaper and faster route. A rebuild makes sense when the site itself blocks visibility: slow, plugin-heavy, or content that only appears after JavaScript runs. Do you build online stores too? Yes. We work with a custom product data model — variants, minimum order quantities, per-customer pricing — with our own ordering logic, payment and invoicing integration, plus product structured data so your products can appear with price and stock in results and AI answers. Who owns the code? You do. On handover you receive the full source code and every access credential, with no licence fee and no mandatory monthly plan. We build on established technologies so any developer can take it over. Who writes the code? The same workshop that runs the GEO programs — we also do development under the RootCR name (rootcr.com). There is no subcontractor chain: the person who writes the quote writes the code and fixes the bugs.
