Build for ChatGPT
Build a website ChatGPT actually quotes.
ChatGPT search has different rules than Google search. Different crawler, different ranking signals, different output. The fastest way to be quoted in ChatGPT is to ship a site engineered for the way ChatGPT reads, not the way Google indexes.
In one paragraph
ChatGPT picks pages it can fetch (GPTBot allowed in robots), parse cleanly (Schema.org JSON-LD present, content not buried in design components), navigate (llms.txt present), and chunk into citable passages (200-500 word headed sections, one topic per section, direct answers to questions). Sites that pass all four get quoted disproportionately. Sites that fail any one of them disappear from ChatGPT's recommendations.
What GPTBot actually fetches
GPTBot is OpenAI's web crawler. It identifies itself in the User-Agent string and reads robots.txt. If you do not explicitly allow it, many CDN defaults block it. We have audited builders where the default robots.txt disallows every AI crawler; the user's site cannot be quoted by ChatGPT no matter how good the content is.
The minimum robots.txt block
User-agent: GPTBot
Allow: /
User-agent: ChatGPT-User
Allow: /
User-agent: OAI-SearchBot
Allow: /BuilderWeb ships this block in every site's robots.txt by default.
What ChatGPT parses, in priority order
-
1. Schema.org JSON-LD
When JSON-LD is present, the parser knows for certain what each block is: an FAQ answer, a price, an opening time, an author. When JSON-LD is missing, the parser approximates from HTML structure. Approximations get quoted less often because they have lower confidence.
-
2. llms.txt
A simple, predictable file at the root that lists the pages an AI agent should care about, what each page is for, and how they relate. Anthropic, Perplexity and ChatGPT-style agents already use it; Google has not formally adopted it but does not penalise its presence.
-
3. Section headings and chunk boundaries
ChatGPT's retrieval splits a page into roughly 200-500 word chunks at H2 and H3 boundaries. Long unbroken paragraphs and walls of marketing copy do not chunk well; short headed sections with one topic each do.
-
4. Direct-answer paragraphs near the top
If a user prompt is "what is X?", ChatGPT prefers to quote the paragraph on your page that opens with "X is...". Burying the lede inside a long story makes you uncitable for the most common prompts.
-
5. Outbound citations and authority signals
Author bylines with Person schema, last-updated dates, and outbound citations to authoritative sources signal that the page is maintained by someone responsible for accuracy. ChatGPT's grounding step weights this.
Common mistakes that kill ChatGPT visibility
- ·Default-block robots.txt. Several CDN defaults disallow every crawler that is not Googlebot.
- ·Content rendered only client-side. If the HTML response is empty until JavaScript runs, GPTBot may not see your content at all.
- ·No JSON-LD, ever. The single most common gap on builder-generated sites.
- ·Buried lede. Marketing copy at the top, real answer 800 words in. ChatGPT quotes the chunk that contains the answer; if the chunk is wrong, ChatGPT quotes a competitor.
- ·Stale dates. "Updated 2022" tells ChatGPT to weight the page lower. Active sites with current dates get cited more.
How BuilderWeb generates ChatGPT-friendly sites by default
Every BuilderWeb site ships:
- ✓robots.txt with explicit Allow for GPTBot, ChatGPT-User, OAI-SearchBot, and the rest of the AI-crawler ecosystem
- ✓Sitewide Schema.org JSON-LD: Organization, WebSite, Article, FAQPage, Breadcrumbs, Product, Service where they apply
- ✓llms.txt and llms-full.txt at the root, regenerated when content changes
- ✓Pages structured into 200-500 word headed sections with single topics
- ✓Direct-answer paragraphs at the top of each page
- ✓Author byline with Person schema and last-updated date
- ✓Static HTML (not client-rendered) so GPTBot can read the page on first fetch
