FAQ

What is GEO?

Generative Engine Optimization. More people now ask ChatGPT or Gemini instead of typing into a search box, so it matters whether AI cites your company in its answers. We add answer-first content, structured data and clear company facts so AI can read and quote your site.

Do SEO and GEO need separate work?

They share the same foundation: a fast, well-structured site reads well to both search engines and AI. So we do them together.

How long does it take and what does it cost?

It depends on the screens and features. Send us your plan and we will reply with a schedule and quote.

Do you maintain the site after launch?

Yes. We handle fixes, new features and operation after launch.

What kinds of games do you make?

Browser games and Android or iOS games, including localization into other languages.
