Structured content, citation-worthy formatting, entity reinforcement, schema, llms.txt, freshness signals, and cross-platform footprint - all measured against AI citation appearances.

Who this is for

  • Brands losing referral traffic to AI Overviews and answer engines.
  • Mid-market businesses whose category is being summarized by LLMs in ways they cannot control.
  • B2B and platform companies whose buyers research with ChatGPT and Perplexity before they ever land on a website.
  • D2C brands that want their entity profile referenced consistently across AI surfaces.

What you get

  • AI search audit - citation footprint across ChatGPT, Perplexity, Gemini, and Google AI Overviews with a prioritized improvement plan.
  • Structural optimization - TL;DR blocks, question-based headings, declarative sentences with concrete numbers, lists and tables.
  • Schema markup - Organization, WebSite, Service, FAQPage, Article, Person - JSON-LD validated against Schema.org and the Rich Results Test.
  • llms.txt and llms-full.txt - published at the root, with a clean markdown index of canonical pages and a concatenated full-content variant.
  • Entity reinforcement - consistent NAP, founder bios, and service descriptions across LinkedIn, Crunchbase, G2, Clutch, GoodFirms, Glassdoor, and industry directories.
  • Freshness signals - last-updated dates on evergreen content, content refresh cadence, and a programmatic refresh playbook.
  • Citation tracking - Otterly.ai, Profound, or HubSpot AI Search Grader to monitor brand mentions across ChatGPT, Perplexity, and Gemini.

Frequently asked questions

Still have a question? Talk to a real human on our team - we usually reply within one business day.

What is AI search engine optimization?
The practice of preparing your site, content, and entity profile to be retrieved and cited by AI answer engines - ChatGPT, Perplexity, Gemini, Claude, and Google AI Overviews. Also called GEO, AEO, or LLMO.
Is this different from SEO?
Related but distinct. SEO targets search engine ranking pages. AI search optimization targets AI summary and citation surfaces. Strong technical SEO is a foundation - but AI search rewards different structural and entity signals.
What is llms.txt and do I need it?
llms.txt is an emerging convention for telling LLM crawlers which content to prioritize. It is a markdown index of canonical pages at the root of your site. Publishing it does not guarantee citation but it removes a low-cost obstacle.
How do you measure AI search results?
Citation appearances across ChatGPT, Perplexity, Gemini, and Google AI Overviews - tracked with tools like Otterly.ai or Profound - plus downstream brand-search lift and direct traffic from AI surfaces.
How long until I see AI citations?
Structural and schema lifts can move citations within 8-16 weeks. Entity reinforcement compounds over 3-6 months.
Can I optimize for AI search without losing SEO traffic?
Yes. The structural improvements that help AI search (clear answers, schema, freshness, authority) also help traditional SEO. We sequence the work so both win.
Do you publish content templates and methodology?
Yes - methodology pages are heavily cited by AI systems answering "how does X agency work" queries. Publishing our methodology is part of our own AI search strategy.
How is H4H different from a typical SEO agency adding AEO?
We have built AI SEO playbooks from first principles - schema, structure, entity, llms.txt, freshness, cross-platform footprint, and citation tracking - not as a rebranded SEO add-on.
