AI search optimization

Be the source AI answers cite

AI Overviews, AI Mode, ChatGPT search, Perplexity and Copilot answer first and cite second. We make your site the one they retrieve, trust and quote, and we measure it every week.

RETRIEVAL

Get retrieved

Crawler access for OAI-SearchBot, ChatGPT-User, PerplexityBot and ClaudeBot; Bing indexing (ChatGPT search overlaps Bing's top results far more than Google's); IndexNow; fast, clean HTML. We publish llms.txt too, while being clear that Google says it does not use it.

TRUST

Get trusted

Consistent entity data everywhere (Organization and LocalBusiness schema, sameAs, NAP), named authors, dated pages, cited sources, brand mentions from digital PR.

QUOTABILITY

Get quoted

Answer-first paragraphs, question-form headings, definitions and tables assistants can lift verbatim, original data nobody else has.

What we do, month by month

  1. Baseline: a 40-prompt panel per topic across Google AI Overviews, ChatGPT, Perplexity and Copilot; who is cited today and why.
  2. Access: robots and firewall rules (CDNs often block AI agents by default), Bing Webmaster Tools, IndexNow, sitemap hygiene; llms.txt as a courtesy, not a ranking signal.
  3. Entity work: schema, sameAs, profiles, consistent descriptions of who you are across the web.
  4. Answer-first rewrites: the pages that should be cited get openings that answer, headings that ask, and facts that can be quoted.
  5. Mentions: data-led assets pitched to publications and communities the assistants already trust.
  6. Measurement: citation share, AI referrals and leads in your monthly report, with the panel re-run weekly.

What we will not claim

Nobody can guarantee a citation, and the assistants change weekly. What we can show is the panel moving, the referrals arriving and the leads that follow, with dates.

Questions

What is AI search optimization?

Making a website visible and quotable in AI-generated answers: Google AI Overviews and AI Mode, ChatGPT search, Perplexity, Microsoft Copilot and Claude. It combines classic SEO (the AI systems still retrieve from search indexes) with answer-first content, entity consistency, crawler access, structured data and citation tracking.

Is it different from SEO?

It is SEO with a different scoreboard. Rankings still matter because retrieval starts from indexes (Google and Bing). What changes is the emphasis: being the clearest, most quotable, most consistently described source, and measuring citations and AI referrals rather than positions alone.

Should we block AI crawlers?

Blocking training bots (GPTBot, Google-Extended) is a policy choice. Blocking the search and retrieval agents (OAI-SearchBot, ChatGPT-User, PerplexityBot, ClaudeBot) removes you from the answers your customers read. We recommend allowing retrieval and deciding separately on training.

How do you measure it?

Weekly prompt panels per topic across the assistants, citation share, AI referral sessions in GA4 (chatgpt.com, perplexity.ai, copilot.microsoft.com referrers and utm_source=chatgpt.com), crawler activity in server logs, and leads attributed to those sessions.
