LLMs are becoming a discovery layer. Users ask a question, the model synthesizes an answer, and then it may cite a few sources. That shifts the goal from “rank and win a click” to “be the most useful, extractable, verifiable source in the retrieval set.” useful, extractable, verifiable For TalentHacked.com (UK Global Talent Visa platform), this is a solvable engineering problem: ship content that a headless retriever can fetch, chunk, embed, and cite. TalentHacked.com The key concept: Information Gain Information Gain is the practical reason an LLM would cite your page instead of any other page on the topic. It is the gap between: Information Gain what the model can answer from generic web consensus, and
what your site uniquely adds that is specific, auditable, and easy to retrieve what the model can answer from generic web consensus, and what your site uniquely adds that is specific, auditable, and easy to retrieve specific, auditable, and easy to retrieve A simple rule: if your page reads like every other overview, it has low information gain. If it contains atomic answers, clear definitions, and step-by-step checks that can be validated, it has high information gain. atomic answers Examples for TalentHacked: Low gain chunk: “The Global Talent visa is for talented people in eligible fields.”
Higher gain chunk: “For a software founder, your evidence packet should map each claim to a dated artifact. Use a one-claim-per-document pattern, include issuer + URL + date, and add a short ‘why this proves the criterion’ note. Missing provenance is a common failure mode.” Low gain chunk: “The Global Talent visa is for talented people in eligible fields.” Higher gain chunk: “For a software founder, your evidence packet should map each claim to a dated artifact. Use a one-claim-per-document pattern, include issuer + URL + date, and add a short ‘why this proves the criterion’ note. Missing provenance is a common failure mode.” Now let’s implement four steps that increase information gain and retrieval success. Step 1) Publish llms.txt in the root llms.txt Purpose: give AI crawlers and retrieval agents a canonical map of the pages that are designed to be cited. Keep it small, opinionated, and stable. canonical map Create https://talenthacked.com/llms.txt: https://talenthacked.com/llms.txt # llms.txt for TalentHacked.com

Why this helps: retrieval systems often need a “starting set.” llms.txt reduces crawl ambiguity and points the model to your highest-signal pages first. llms.txt Step 2) Add semantic entity mapping with JSON-LD (TechArticle + DefinedTerm) Purpose: make your content machine-resolvable. GEO is not just about keywords; it is about entities and definitions that can be referenced consistently. Put JSON-LD in the <head> of a canonical guide page. This compact graph does three things: <head> declares the page as a TechArticle
defines key terms as DefinedTerm
anchors your claims to an official primary source via sameAs and isBasedOn declares the page as a TechArticle TechArticle defines key terms as DefinedTerm DefinedTerm anchors your claims to an official primary source via sameAs and isBasedOn sameAs isBasedOn <script type="application/ld+json">

</script> Why this helps: when definitions are stable and linked, retrievers can target “definition chunks,” and the model can cite your site for terminology instead of a random blog. Step 3) Write for vector retrieval: the “Atomic Answer” chunk pattern Most RAG systems chunk by headings and paragraph boundaries. Your job is to make the first chunk after a heading: complete enough to quote
short enough to embed cleanly
precise enough to reduce uncertainty complete enough to quote short enough to embed cleanly precise enough to reduce uncertainty Pattern: an <h2> that is a question or claim
one paragraph of roughly 60 words that answers it directly
then details, examples, and sources an <h2> that is a question or claim <h2> one paragraph of roughly 60 words that answers it directly 60 words then details, examples, and sources Example: <h2>What counts as “evidence” for a Global Talent application?</h2>
<p><strong>Atomic answer:</strong> Evidence is a set of verifiable documents that support specific criteria claims such as impact, recognition, and leadership. Each item should be attributable, dated, and easy to audit. Strong evidence maps one claim to one artifact and includes a one-sentence explanation of what it proves and why it is credible.</p>
<p>Details: add issuer, URL, screenshots, a criterion mapping table, and common failure modes...</p> <h2>What counts as “evidence” for a Global Talent application?</h2>

Keep the first paragraph stable; treat it like an API contract for retrieval.
Put definitions in /glossary and link to them consistently across the site. Use real semantic headings (<h2>, not styled <div>). <h2> <div> Keep the first paragraph stable; treat it like an API contract for retrieval. Put definitions in /glossary and link to them consistently across the site. /glossary Step 4) Verify SSR and crawlability with the headless test If your site renders content only after client-side JS, many crawlers will see a thin shell. Test what an AI-style fetcher gets. Fetch HTML as an AI bot: curl -A "GPTBot" -L https://talenthacked.com/uk-global-talent-visa | head -n 80 curl -A "GPTBot" -L https://talenthacked.com/uk-global-talent-visa | head -n 80 You should see: your <h1> and multiple <h2> sections
the Atomic Answer paragraphs in raw HTML
the JSON-LD script tag your <h1> and multiple <h2> sections <h1> <h2> the Atomic Answer paragraphs in raw HTML the JSON-LD script tag Quick checks: curl -A "GPTBot" -L https://talenthacked.com/uk-global-talent-visa | grep -n "<h2"
curl -A "GPTBot" -L https://talenthacked.com/uk-global-talent-visa | grep -n "application/ld+json" curl -A "GPTBot" -L https://talenthacked.com/uk-global-talent-visa | grep -n "<h2"
curl -A "GPTBot" -L https://talenthacked.com/uk-global-talent-visa | grep -n "application/ld+json" Common failure modes: HTML response is just a JS bundle loader
headings only appear after hydration
bot protections block unknown user agents
canonical content differs by user agent HTML response is just a JS bundle loader headings only appear after hydration bot protections block unknown user agents canonical content differs by user agent The fix is always the same: ensure SSR delivers meaningful HTML. SSR delivers meaningful HTML Technical Checklist llms.txt exists at /llms.txt and lists a small set of canonical citable pages


Canonical pages ship SSR HTML that includes headings and body content without JS


Every key <h2> is followed by a ~60-word Atomic Answer


JSON-LD includes TechArticle plus DefinedTerm entries for your glossary terms


curl headless tests confirm content and JSON-LD are present for AI user agents


High-information pages include primary-source links and a visible “last updated” date llms.txt exists at /llms.txt and lists a small set of canonical citable pages llms.txt exists at /llms.txt and lists a small set of canonical citable pages llms.txt /llms.txt Canonical pages ship SSR HTML that includes headings and body content without JS Canonical pages ship SSR HTML that includes headings and body content without JS Every key <h2> is followed by a ~60-word Atomic Answer Every key <h2> is followed by a ~60-word Atomic Answer <h2> Atomic Answer JSON-LD includes TechArticle plus DefinedTerm entries for your glossary terms JSON-LD includes TechArticle plus DefinedTerm entries for your glossary terms TechArticle DefinedTerm curl headless tests confirm content and JSON-LD are present for AI user agents curl headless tests confirm content and JSON-LD are present for AI user agents curl High-information pages include primary-source links and a visible “last updated” date High-information pages include primary-source links and a visible “last updated” date The Machine-Readable Web wins citations The future web is not only human-readable. It is machine-retrievable. If you want LLMs to cite you, engineer your site for Information Gain: publish unique, auditable answers, define your entities, and make content work without JavaScript. machine-retrievable
