AI visibility

How AI assistants decide whom to cite

Most AI assistants answer by searching the web, reading a few top pages and citing them. To be cited, your site must be open to their crawlers, rank for the underlying search, and contain a clear, sourced passage that answers the question.

The basics

SEO, AEO and GEO — what’s the difference?

Short answer

SEO gets your pages ranked in search results. AEO shapes those pages so search features and voice assistants can quote a direct answer from them. GEO makes your content easy for AI assistants such as ChatGPT, Perplexity and Google AI Overviews to find, trust and cite. Each builds on the one before it.

Frequently asked questions

Which should I start with: SEO, AEO or GEO?

Start with SEO. A page has to be crawlable and indexed before an answer engine can quote it or an AI assistant can cite it. Then add answer-first structure (AEO) and sourced, quotable facts (GEO) to the pages that already rank.

Can one page be optimised for all three at once?

Yes, and it should be. A page with a clear question heading, a short direct answer, supporting lists or tables, cited sources and correct schema serves search engines, answer engines and AI assistants with the same content.

What does THB SEO do?

THB SEO is the search and AI-visibility service of THB — The House of Business in Dhaka. We audit, fix and grow websites so they rank on Google and Bing, get quoted in answer boxes and get cited by AI assistants, and we publish free tools and guides on the same subjects.

Do you work with businesses outside Bangladesh?

Yes. All work can be done remotely, and our team writes and optimizes in English, Bangla and other languages with THB’s translation team.

How is this website itself built for SEO, AEO and GEO?

Every page is pre-rendered static HTML, has a canonical URL, Open Graph tags and a linked JSON-LD graph (Organization, WebSite, WebPage, Article, BreadcrumbList, FAQPage). Robots.txt explicitly allows AI retrieval bots, and /llms.txt is generated from the same content as the pages.
