What is AI visibility (GEO)?

Traditional websites speak only to people. Our Advanced infrastructure encodes your brand as a semantic data network (an entity) that ChatGPT, Gemini and Google's AI search can understand. AI can then recommend you as a trusted source when people ask about your industry.

Frequently asked questions

What is the difference between Essential and Advanced?

Essential is a custom-coded, fast and secure website with technical SEO in place. Advanced adds an AI visibility layer on the same foundation: an entity model, external profile work and GEO-focused page architecture so Google, ChatGPT and Gemini recognize your business as one accurate identity, followed by 90 days of follow-up after delivery.

How long does delivery take?

Essential is delivered in 15 days. Advanced is delivered in 30 days, followed by 90 days of tracking and improving how search engines and AI answers identify your business.

Who owns the domain and hosting?

The domain and server (VPS) are registered to your account and stay with you when the work ends. We set them up at no extra charge; you only pay the hosting provider's fee.

Do I get the source code?

Yes. All source code is handed over, so you're never dependent on us for future development.

Do you guarantee performance?

Yes. If any Google PageSpeed Insights metric is below 90, we revise the site for free.

Why not WordPress or a ready-made template?

Templates ship with code and plugins most sites never use, which costs speed, security and maintenance. Custom code contains only what's needed, and because pages are rendered on the server, search engines and AI crawlers read the content completely.

Is it guaranteed that ChatGPT will recommend my site?

No; nobody can honestly guarantee that, because no one controls how AI assistants choose sources. With Advanced we build the infrastructure needed for your business to be understood correctly and report the change with baseline and outcome measurements.

What does the starting price cover?

Everything listed on the cards and in the delivery scope is included. Needs outside that scope, such as extra pages or custom integrations, are priced separately after a conversation.

Free

How do ChatGPT and Gemini describe your business?

We'll check your site and how AI assistants present your business for free, and tell you plainly what's missing and which package fits.
