How Indian Manufacturers Can Get Found by ChatGPT and AI Search Tools
Kalk Solutions Editorial
TL;DR
AI tools like ChatGPT and Perplexity are increasingly used for early-stage supplier research. Most Indian manufacturer websites are invisible to these tools because they are not structured for AI to read and reference. This guide covers what AI Engine Optimisation means for manufacturers and how to start.
Quick answers
- What is AEO?
- AI Engine Optimisation. The practice of structuring a website so AI tools like ChatGPT, Perplexity, and Google AI Overviews can read it and reference it in answers to buyer questions.
- Are buyers really using ChatGPT for supplier research?
- Yes, increasingly for early-stage research. They ask things like which Indian manufacturers make X for Y industry with Z certification. The AI synthesises an answer from indexed content.
- What is llms.txt?
- A simple text file at the root of your website, similar to robots.txt, that guides AI crawlers to the most important content on your site. Almost no Indian manufacturer websites have one.
A buyer at a US-based industrial distributor opened ChatGPT and typed "which Indian manufacturers make precision turned parts for valves in 6061 aluminium with IATF 16949 certification". ChatGPT gave him a list of six names with one-line descriptions of each. He emailed two of them the same day.
None of the six names had bid for that conversation. The AI surfaced them because of how their websites were structured. The other 40 Indian suppliers who could have done the work were simply not in the answer. They were not present in the conversation that decided who got the first email.
This is happening more often than most Indian manufacturers realise. AI search is not replacing Google yet, but it is increasingly where early-stage supplier research begins, especially among international buyers.
What is AI search visibility and why it matters now
AI Engine Optimisation, or AEO, is the practice of making a website readable and quotable by AI tools. ChatGPT, Perplexity, Google AI Overviews, Claude, and others.
These tools answer buyer questions by synthesising from indexed content. If your website states what you do in clear, specific, fact-shaped sentences, the AI can pull from it. If your website talks about quality commitment and innovation, the AI has nothing to extract.
The shift matters now because the percentage of buyers using AI for first-pass supplier research is rising fast, and the suppliers who win the first-pass shortlist usually win the deal.
How AI tools decide which companies to mention
AI tools favour content that does three things well. It states facts clearly, in plain language. It is organised so each fact lives in a predictable place. It is reinforced by other sources, customer reviews, directory listings, founder LinkedIn posts, news articles.
A clear capability page that says "we manufacture CNC turned components in 6061 aluminium, 7075 aluminium, SS304, SS316, and brass, in volumes from 500 to 50,000 pieces, with tolerances to plus minus 0.01 mm, certified to IATF 16949, supplying valve and automotive Tier-1 OEMs across India and Gulf" is something an AI can extract and reuse. A page that says "we are a trusted partner offering world-class precision solutions" is not.
Our website RFQ generation guide covers the page structure in detail. The same structure that wins RFQs also wins AI mentions.
The llms.txt file, what it is and why manufacturers should have one
llms.txt is a simple file you place at the root of your website, the same way robots.txt sits there. Its job is to point AI crawlers to the most important content on your site, in a clean, machine-readable form.
For a manufacturer, a useful llms.txt lists your capability pages, your certification pages, your case studies, your founder bio, and key product or process pages. It removes ambiguity about what matters on your site.
Almost no Indian manufacturer websites have an llms.txt today. Adding one is a 2-hour job that puts you ahead of 99 percent of your competitors on AI discoverability. The standard is documented at llmstxt.org.
Structuring content so AI tools can read and use it
Three rules cover most of it.
First, write in claims, not adjectives. Replace "best in class quality" with "first-pass yield of 98.7 percent on critical aerospace parts in the last 12 months". The AI can quote a number. It cannot quote a feeling.
Second, use clear FAQ sections at the end of every important page. AI tools love structured question-answer pairs because they map directly to how buyers ask questions. Every capability page should have 5 to 8 FAQs covering tolerance, lead time, MOQ, certification, sample policy, and shipping.
Third, give every fact a clear context, what, who for, what proof. "We CNC turn 6061 aluminium for two-wheeler Tier-1 OEMs in Aurangabad, with IATF 16949 certification audited in March 2026" is one sentence that does three jobs at once.
This is early. That is the opportunity.
The window is narrow. Once buyers fully shift to AI for supplier research, and once your competitors notice, the playing field will look like Google SEO does today, crowded and expensive.
Right now, almost no Indian manufacturer has structured their site for AI tools. Adding an llms.txt, restructuring capability pages, and writing FAQ sections takes 6 to 10 weeks of focused work. The result is being among the first companies an AI mentions in your category, for at least the next 12 to 18 months while competitors catch up.

Questions about this topic
Do I need to choose between Google SEO and AI search?
No. The same structured, specific, fact-stated content that wins AI tools also performs well on Google. AEO is an extension of good SEO, not a replacement.
What kinds of buyer queries do AI tools answer well?
Open-ended sourcing questions, like which Indian manufacturers do AS9100 CNC machining for aerospace, or which Pune suppliers do sheet metal fabrication for solar. The AI returns a shortlist.
How do I check if ChatGPT knows my company?
Ask it directly. Open ChatGPT or Perplexity and ask which Indian manufacturers do your specific capability for your specific industry. If you are not in the answer, you have an AEO gap.
How long does it take to see AI search visibility?
AI tools index slower than Google. Expect 2 to 4 months for clear capability content and llms.txt to appear in answers, longer for AI overviews.
Is this a real opportunity or hype?
Real, but early. The opportunity is precisely because almost no Indian manufacturers have done it. Being among the first answers an AI gives is a moat that closes within 18 to 24 months.
