12 things hurting your AI visibility

llms.txt
No /llms.txt: the emerging standard map that tells LLMs and agents what your site is and where the key docs are.
→ Publish the generated llms.txt below at https://yoursite/llms.txt.
JSON-LD structured data
No schema.org JSON-LD found.
→ Add JSON-LD (generated below) so engines know your entity, product and pricing unambiguously.
Entity / product schema
No Organization / Product / SoftwareApplication schema.
→ Add Organization + Product/SoftwareApplication schema with name, url, logo, sameAs (socials), offers.
One clear H1
No H1 heading.
→ Use exactly one H1 that names the product and its core benefit.
Scannable section headings
0 H2 headings. LLMs chunk pages by headings.
→ Break the page into H2 sections: what it is, how it works, pricing, FAQ.
Machine-usable interface (API / MCP)
No OpenAPI spec, MCP server or API docs discovered. AI agents can read about you but can't act (sign up, query, buy).
→ Expose an MCP server or OpenAPI spec and link it from llms.txt so agents can use your product, not just read about it.
Pricing is machine-readable
No pricing found. Agents comparing tools for users skip products without clear prices.
→ Add a plain-HTML /pricing page and `offers` in your JSON-LD.
Descriptive title tag
"Substack" (8 chars)
→ Use a 15-70 char title: `Product: what it does for whom`.
Meta description
30 chars.
→ Write a 50-160 char description stating exactly what the product does.
Docs / help content linked
No docs/help links. Agents rely on docs to answer how-to questions about you.
→ Publish public docs/how-to pages and link them from the homepage and llms.txt.
Question & answer content
No FAQ section found.
→ Add an FAQ answering the exact questions buyers ask ChatGPT ("best X for Y", "X vs Y", "how much does X cost").
Linked brand profiles
0 social/profile links. Corroborating profiles help AI trust and identify your brand.
→ Link your X, LinkedIn, GitHub, Product Hunt pages and list them in schema `sameAs`.
