- GENERATIVE ENGINE OPTIMIZATION FOR DIALNEXA
They told the AI not to read them. So it didn't.
DialNexa sells voice AI agents, yet its own site was invisible to the AI engines buyers now ask first. The reason was hiding in one file: robots.txt was blocking the crawlers. We opened the door, pointed the content at the questions people actually type, and in eight weeks AI assistant traffic to the site more than tripled.

- The Client
DialNexa builds the voice agents buyers now research through AI.
A conversational and voice AI platform competing in one of the most crowded, fastest moving categories in Indian tech. Its buyers are exactly the kind of people who open ChatGPT or Gemini and ask “best voice AI agents in India” before they ever reach a search box. That made AI visibility a commercial priority, not a vanity metric.
Industry
Voice AI and conversational AI platforms
Primary Market
India, in a field led by Vapi, Yellow.ai, Gnani and Retell
The Project
A GEO-first engagement: visibility inside AI answers, not just on the results page
Where They started
AI visibility score of 0 in India · zero AI engine mentions · AI crawlers blocked in robots.txt
The Buyer
Founders and ops leaders who ask an AI assistant to shortlist vendors before taking a call
Primary Goals
Turn AI engines into a source of qualified, high-intent traffic and signups
- The Challenge
A voice AI company
the AI had never heard of.
The irony wrote itself. DialNexa sells AI agents, but when a buyer asked an AI engine for options, DialNexa did not come up. Our audit found the cause was not a content problem first. It was a permissions problem, compounded by a content base pointed at the wrong terms.
The Door Was Bolted Shut
The site's robots.txt was blocking AI crawlers from training and indexing the content. The engines that decide who gets mentioned in an answer were being told, in writing, to stay out. Nothing downstream could work until this was fixed.
Zero Presence in AI Answers
An AI visibility score of 0 in India and no brand mentions across ChatGPT, AI Overview, AI Mode or Gemini. An entire research channel, the one DialNexa's own buyers were using, was returning nothing.
Ranking for the Wrong Things
The content that did rank was generic BPO glossary material, informational but not commercial. The terms that sell voice AI sat far outside page one, so even existing traffic rarely matched a buyer.
Outgunned on Authority
Category leaders already held deep AI citation footprints and years of domain authority. DialNexa was starting from a low base against competitors the AI engines already trusted and named by default.
Four phases.
Open the door, then earn the mention.
GEO only works if the engines can read you, so the sequence was non-negotiable. Fix the crawl access first, find the exact prompts buyers use, publish answers to them, then build the off-site authority that makes an AI engine confident enough to name you.
Audit & Access
- Full site audit to find what was holding AI visibility at zero
- robots.txt rewritten to allow the AI crawlers that had been blocked
- Technical SEO cleared so new content could be crawled, indexed and cited
- Analysis run across Semrush, Ahrefs and Yozigo to map the real gaps
Prompt & Query Research
- Identified the core prompts and queries people use when searching for voice AI agents
- Separated buyer-intent questions from generic informational noise
- Mapped each query to the AI engine and funnel stage it belongs to
- Prioritised the commercial terms competitors had left open
Answer-First Content
- Published content built directly around those real queries
- Formatted for extraction, so engines could lift a clean answer
- Comparison and alternatives pages aimed at vendor shortlisting moments
- Content structured to turn a cited page into a clicked link
Authority & Off-Page
- Published original industry reports as citable, linkable assets
- Off-page campaign built high authority backlinks for the domain
- Secured mentions on relevant third party sites in the category
- Gave the AI engines the external corroboration they reward
Eight weeks in, the needle moved.
The Metric That Matters Most
The engagement started on 11 August. GA4's own period comparison, the eight weeks after against the eight weeks before, is the cleanest read on what changed. AI assistant sessions to the site nearly tripled, and they arrived more engaged than any other channel.

Quality, Not Just Volume

| Cited pages | low single digits | 10 |

| Organic keywords (Semrush, India) | baseline | 194 (+25%) |
| Referring domains | building | 729 |
Five decisions that moved the needle fast.
GEO rarely shows results in eight weeks. This did, because the single biggest blocker was removed on day one and everything after it was aimed at buyer intent rather than traffic volume.
We Found the Bolt First
Most GEO programmes start by writing content. We started by reading robots.txt. The crawlers were blocked, so no amount of content could have surfaced in an AI answer. Unblocking them unlocked everything downstream.
Content Built on Real Prompts
We identified the exact prompts and queries buyers use when searching for voice AI agents, then published answers to them. Not keywords sprinkled into blogs, but content shaped to be the answer an engine lifts.
Aimed at the Buyer, Not the Chart
The old content ranked for BPO glossary terms that never converted. We pointed the new content at commercial, vendor-shortlisting intent, which is why the signup page moved almost as fast as the traffic.
Reports the AI Could Cite
Original industry reports gave the engines something concrete to reference, and the off-page campaign built the high authority backlinks and third-party mentions that make an engine trust a source enough to name it.
Measured What Converts
We tracked AI assistant sessions and signup actions, not just rankings. AI-referred visitors turned out to be the most engaged on the whole site, which told us the channel was worth doubling down on.
AI Engine Optimisation
As buyers increasingly research using ChatGPT and Claude, we built Dialnexa's presence on AI platforms through sturctured, AI-first content.
One file was costing them an entire channel.
The most valuable thing we did for DialNexa took about ten minutes to fix and would have cost them months if it had gone unnoticed. The rest of the engagement was the patient work of earning citations, but it could only begin once the engines were allowed in.
The Audit Finds the Bolt
AI visibility sat at zero in India. The audit traced it to robots.txt, which was disallowing the AI crawlers outright. A company selling AI agents was invisible to AI engines by its own configuration.
Access, Then Intent
Crawlers unblocked and technical SEO cleared. In parallel, we mapped the real prompts buyers use for voice AI, using Semrush, Ahrefs and Yozigo, and prioritised the commercial terms nobody owned yet.
Publishing the Answers
Answer-first content went live against those queries, formatted so engines could extract it cleanly. Citations in India began rising from their March base of around five toward the mid-twenties.
Building the Corroboration
Original industry reports published as citable assets, backed by an off-page campaign earning high authority backlinks and third-party mentions. External trust signals the engines reward.
The Channel Comes Alive
AI assistant sessions up 208%, signup views up 185%, impressions up 81%, and AI-referred visitors engaging longer than any other channel. A dead channel is now the most qualified one.
AI citations in India since March, the leading indicator that the visibility score follows next.
- Ready to Grow?
Is your brand invisible to the AI?
Your buyers are already asking ChatGPT and Gemini who to shortlist. If your site is blocking the crawlers, pointed at the wrong queries, or simply never mentioned, you are losing deals you never see. The first fix is often faster and cheaper than you would expect.
- Check whether your site even lets the AI engines in
- Find the exact prompts your buyers ask AI
- Publish content engines can lift as the answer
- Build the authority that earns the citation
