Why ChatGPT Dominates AI Search Referrals, and What It Actually Means for Bangalore Businesses

A new study analysing 6.77 million AI-driven website sessions found that ChatGPT alone accounts for 92.4 percent of all traffic coming from standalone AI platforms, dwarfing Gemini, Claude, and Perplexity combined. For a Bangalore business trying to prioritise where to invest limited AI-search attention, this number matters, but not in the simple “just optimise for ChatGPT” way the headline suggests.

What the Study Actually Found

Search Engine Land reported on Previsible’s third AI Traffic Study, analysing 6.77 million LLM-driven sessions across 166 websites over 19 months, finding that monthly AI-referred sessions grew 9.9 times over the period, reaching 644,478 in May 2026, with ChatGPT responsible for 92.4 percent of that standalone-platform traffic. The original report, published via Business Wire, confirms Gemini grew 3.2 times over the same period and now sits as the clear second-place platform, while Claude grew 64-fold and passed Perplexity in March 2026.

The growth itself is the more important number for most businesses, even ahead of the ChatGPT-specific share. Monthly AI-referred sessions across the study’s 166 sites nearly grew tenfold in nineteen months. Whatever share ChatGPT holds within that growth, the underlying trend, AI platforms sending real, measurable traffic to real websites, is accelerating rapidly and shows no sign of plateauing.

The Nuance the Headline Number Hides

Here is the detail worth taking seriously before reallocating any budget: this 92.4 percent figure covers standalone AI platforms specifically, ChatGPT, Gemini, Claude, Perplexity, visited directly rather than through Google. It does not include AI discovery happening inside Google’s own results, AI Overviews and AI Mode, which the report itself describes as remaining the larger overall centre of AI discovery. The study’s own authors recommend prioritising Google’s AI surfaces first, and treating ChatGPT as the leading standalone alternative second, precisely because Google’s AI features currently reach a broader base of everyday searchers than any standalone chatbot does on its own.

This matters enormously for how a Bangalore business should actually act on this data. The genuine takeaway is not “abandon Google-focused GEO work and optimise purely for ChatGPT.” It is that the fundamentals already covered in how Bangalore businesses can get found by AI search, entity clarity, direct-answer content, structured data, serve as the foundation for citation across every AI surface, Google’s own AI features and standalone platforms alike, and a business built on that foundation is well positioned for both rather than needing a separate ChatGPT-specific strategy.

This is precisely the same reasoning behind our checklist for AI search readiness when hiring an agency: an agency chasing whichever platform is trending in the news that month is solving the wrong problem. The genuine question worth asking any prospective SEO company in Bangalore is whether they understand the underlying signals that transfer across platforms, not whether they have a ChatGPT-specific tactic of the month.

Why E-Commerce and Certain Sectors Should Pay Closer Attention

The Previsible study found e-commerce AI referral traffic rose 37-fold over the study period, with ChatGPT responsible for nearly all of that specific traffic, since no other standalone platform currently sends meaningful referral volume to e-commerce properties. A Bangalore business selling products directly online, rather than offering local services, faces a genuinely different calculus than a typical service business. For this segment specifically, ChatGPT’s dominance within standalone platforms is worth taking more seriously as a direct action item, since the study suggests shoppers increasingly arrive at product pages with purchase intent already formed through a ChatGPT conversation.

Claude’s 64-fold growth and its specific strength among developers, technical buyers, and professional services is a second sector-specific signal worth noting. A B2B technology or professional services business, similar to the manufacturing exporters and CA and financial firms covered elsewhere in this series, may find Claude citation genuinely relevant in a way a consumer retail business would not.

What Actually Changed for Perplexity

The study found Perplexity’s monthly sessions declined 61 percent since March 2025, attributed partly to the platform shifting toward keeping users inside its own browser and agent tools rather than sending them out to source websites. This is a useful reminder that platform-level product decisions, not just content quality, shape referral volume. A business doing everything right on its own content can still see referral traffic from a specific platform decline for reasons entirely outside its control, which is exactly why diversifying citation across multiple AI surfaces, rather than betting everything on one platform’s current behaviour, remains the sounder long-term strategy.

Measuring This Properly Rather Than Reacting to a Headline

The temptation with any striking statistic like “92.4 percent” is to treat it as an immediate call to action. The more useful response is to check what your own business’s actual AI referral data shows before changing anything. Search Console’s AI Performance report, where available, alongside GA4 referral tracking, tells you which platforms are actually sending your business traffic right now, which may look quite different from the aggregate study average depending on your specific sector and customer base.

A Bangalore service business with no e-commerce component may find its AI referral traffic, however small currently, splits more evenly across Google’s AI Overviews, ChatGPT, and occasional Perplexity or Claude sessions, since the study’s e-commerce-specific ChatGPT concentration does not necessarily apply the same way to a local service category. Checking your own data rather than assuming a national, cross-industry average applies directly to your business is the more disciplined response to a headline number like this one.

A Practical Starting Point

Do not restructure your entire content and SEO strategy around ChatGPT specifically based on this one number. Continue building the entity clarity, structured data, and direct-answer content foundation that serves citation across every AI surface, since this is what the study’s own authors recommend prioritising first. If your business sells products directly online, pay closer attention to ChatGPT-specific behaviour and shopping-related features, since the data suggests this is where standalone-platform referral traffic concentrates most heavily right now. If your business serves technical, professional, or B2B buyers, keep an eye on Claude’s continued growth as a secondary but genuinely rising citation source.

Track your own AI referral traffic directly in GA4 rather than assuming national study averages apply identically to your specific business and sector, since the study itself notes results vary enormously by industry and site structure. A full local SEO and GEO strategy built around genuine specificity, the same principle running through every piece in this series, positions a business well regardless of which specific AI platform happens to dominate the headlines in any given month.
