The AI search market is projected to exceed $40 billion by 2033, and B2B companies that optimize now will capture disproportionate market share as buyer behavior permanently shifts away from traditional search. According to Grand View Research, the AI search engine market was valued at $16.28 billion in 2024 and is growing at a 13.6% CAGR—but the real opportunity lies in the conversion gap: AI search traffic converts at 4.4x the rate of traditional organic search.
This isn’t a distant future trend. Forrester reports that 89% of B2B buyers already use generative AI tools in their purchase process, with 50% now starting their buying journey in ChatGPT or Perplexity rather than Google. The window for first-mover advantage in AI search optimization is closing rapidly, and B2B companies that delay risk permanent invisibility in how modern buyers discover solutions.
The Seismic Shift in B2B Buyer Behavior
B2B purchasing decisions have fundamentally changed as AI search tools become the default research interface for decision-makers. According to 6sense’s 2025 Buyer Experience Report, 94% of B2B buyers now use large language models during their buying process, yet they maintain the same number of vendor interactions—16 touchpoints per person with the winning vendor. The critical difference is that AI makes buyers more informed before human relationships begin.
Millennials and Gen Z now comprise 65% of B2B decision-makers, and this cohort demonstrates starkly different research habits than their predecessors. TrustRadius research reveals that 72% of buyers encounter Google’s AI Overviews during vendor research, while 55% of Gen Z buyers specifically find AI “helpful and easily provides information”—up from just 37% in 2024. These digital-native buyers spend 83% of their buying journey on independent research away from sales representatives.
The implications for vendor visibility are significant. G2’s August 2025 survey of 1,000+ B2B software buyers found that 87% report AI chatbots are changing how they research, with 50% now starting their buying journey in an AI chatbot instead of Google Search—a 71% increase from just four months prior. When buyers prompt questions like “Give me three CRM solutions for a hospital that work on iPads,” they create instant shortlists that completely bypass traditional SEO-driven discovery.
The Attribution Black Hole
Traditional demand generation metrics are increasingly insufficient for measuring buyer engagement. When buyers use ChatGPT to research your category, they still visit websites to verify claims—but their initial discovery happens in what 6sense calls the “Dark Funnel.” Individual touchpoints become harder to track as research moves into opaque channels like LLM conversations.
However, the solution isn’t to panic about disappearing intent data. Intent signals are becoming more valuable precisely because they’re harder to capture through traditional methods. The brands that thrive recognize a critical pattern: with 77% of buyers contacting the eventual winner first and 85% having prior experience with evaluated vendors, the battle is won or lost before explicit engagement begins.
The AI Overviews Impact on Organic Traffic
Google AI Overviews are fundamentally reshaping organic search performance, with CTR declines that demand strategic response. Seer Interactive’s September 2025 analysis of 3,119 search terms across 42 organizations reveals that organic CTRs for queries with AI Overviews plummeted from 1.76% to 0.61%—a 61% decline. Even queries without AI Overviews declined 41% year-over-year.

The data is unequivocal: brands cited in AI Overviews earn 35% more organic clicks and 91% more paid clicks compared to those not cited. This creates a stark visibility divide where optimization for AI citation becomes essential for maintaining search performance.
| Metric | With AI Overviews | Without AI Overviews |
| Organic CTR (Sept 2025) | 0.61% | 1.62% |
| YoY CTR Change | -61% | -41% |
| Click Benefit from Citation | +35% organic, +91% paid | N/A |
The zero-click search phenomenon compounds these challenges. A 2025 Bain & Company study found that 60% of searches now end without clicks, while Pew Research Center documented that searches displaying AI Overviews see click-through rates drop to just 8% compared to 15% for traditional results. By March 2025, AI Overviews appeared for 13.14% of queries—doubling from January’s 6.49%—with projections suggesting 20-25% coverage by year-end.
BrightEdge’s May 2025 research confirms average click-through rates dropped 30%, while GrowthSRC Media documented that Google’s top organic CTR dropped from 28% to 19%—a 32% decline correlating with AI Overview expansion. Position two experienced an even steeper 39% decline from 20.83% to 12.60% year-over-year.
The Rise of AI Search Platforms
Beyond Google, dedicated AI search platforms are capturing significant buyer attention. Perplexity AI processed 780 million search queries in May 2025, tripling from 230 million in mid-2024. The platform now has 22 million active users globally—a 450% increase in 18 months—with 2 million daily visitors demonstrating strong engagement patterns.
The enterprise adoption trajectory is particularly noteworthy. Enterprise usage of Perplexity grew 240% year-over-year, with 15% of Fortune 100 companies now actively using the platform for internal search and research workflows. Developer adoption of the Perplexity API grew to 85,000 active integrations by June 2025, with average monthly API call volume exceeding 360 million.
ICODA is seeing increased demand from B2B SaaS companies recognizing this platform diversification imperative. Where traditional SEO focused exclusively on Google, AI search optimization requires presence across ChatGPT, Perplexity, Gemini, and Google AI Overviews simultaneously. Each platform has distinct content preferences and citation patterns that require specialized optimization approaches.
ChatGPT maintains its position as the dominant AI platform, with around 800 million weekly active users in 2025, roughly doubling from earlier in the year, while Google’s Gemini has seen its monthly audience grow rapidly, narrowing the gap and reaching hundreds of millions of monthly users by late 2025, demonstrating that AI adoption is accelerating across multiple platforms rather than consolidating around a single winner.
Why B2B Companies Are Moving Now
The business case for AI search optimization has reached a tipping point where delay creates compounding competitive disadvantage. According to ICODA’s demand observations, enterprise inquiries have shifted from “what is this” to “how do we start”—indicating market education is complete and execution is now the priority.
Vlad Pivnev from ICODA notes the shift: “CFOs and CTOs are now asking about AI search optimization ROI with the same urgency they previously reserved for paid media. The conversion data is simply too compelling to ignore.”
Several converging factors drive this urgency:
Conversion superiority. AI search traffic converts at 4.4x to 23x the rate of traditional organic search visitors. When Vercel reports that ChatGPT referrals drive approximately 10% of new user sign-ups, the revenue implications become concrete and measurable.
Platform economics favor early movers. Unlike traditional SEO where thousands of competitors fight for ten blue links, AI platforms cite a limited number of sources per response. Early optimization creates defensible positioning before competitive saturation occurs.
Enterprise validation. 92% of Fortune 500 companies now use GenAI tools in operations, validating enterprise-scale commitment that drives B2B marketing investment. The market has moved from experimentation to systematic budget allocation.
Buyer expectations. With 86% of B2B buyers expressing eagerness to use ChatGPT-like tools for product research, companies without AI visibility risk systematic exclusion from modern purchase consideration sets.
Industries Leading the AI Search Optimization Race
Certain sectors have emerged as early movers in AI search optimization, offering lessons for the broader B2B market. Industries ICODA identifies as early movers include fintech, crypto, AI tools, and SaaS companies—sectors characterized by digitally sophisticated buyers, rapid innovation cycles, and intense competition for technical talent and customers.
Financial technology. The fintech sector faces unique visibility challenges as buyers increasingly use AI to compare payment processors, lending platforms, and financial infrastructure. Companies optimizing for queries like “best payment gateway for subscription businesses” or “embedded finance solutions comparison” gain significant first-mover advantage.
Cryptocurrency and blockchain. The crypto ecosystem has been particularly aggressive in AI search optimization, recognizing that decentralized finance, NFT, and Web3 buyers demonstrate high AI tool adoption rates. ICODA has developed optimization strategies specifically tailored to blockchain marketing challenges, combining technical SEO expertise with understanding of cryptocurrency regulations, DeFi protocols, and Web3 community dynamics.
AI tools and infrastructure. Perhaps unsurprisingly, companies building AI products demonstrate sophisticated understanding of AI search optimization. These companies recognize that their target buyers—developers, data scientists, and technical decision-makers—are among the heaviest AI search users and expect to discover solutions through AI-native interfaces.
B2B SaaS. Software companies face the most immediate AI search disruption as software buying research transitions to AI platforms. G2’s data showing AI chat as the top source for building software shortlists creates existential urgency for SaaS vendors to optimize their AI visibility before buyers solidify purchasing preferences.
The GEO Market Opportunity
The market for Generative Engine Optimization services is expanding rapidly as enterprises recognize the strategic imperative. Estimated at $848-886 million by 2024 as Fortune 500 enterprises allocated dedicated budgets, the GEO market is projected to reach $7.3-33.7 billion by the early 2030s, representing a 50.5% CAGR that dramatically outpaces traditional SEO growth.
Major SEO platforms are responding rapidly to shifting market demand. Semrush reported $25 million in annual recurring revenue from AI-driven products in Q2 2025, contributing to a 20% year-over-year revenue increase to $108.9 million. This momentum has been reinforced by strategic moves such as Semrush’s acquisition of Abode, underscoring its push to expand AI-native capabilities and data infrastructure. At the same time, more than 60 commodity GEO tracking tools launched between 2024 and 2025, signaling broad market adoption of AI visibility as a standalone performance category rather than a subset of traditional SEO.
Current GEO service pricing reflects the specialized expertise required:
| Service Level | Monthly Investment | Typical Scope |
| Basic GEO | $1,500 – $3,000 | Single platform, content optimization |
| Advanced GEO | $3,000 – $10,000 | Multi-platform, entity optimization, tracking |
| Enterprise GEO | $10,000 – $30,000+ | Full-stack optimization, custom integrations |
According to ICODA’s demand observations, the most sophisticated enterprises are treating GEO as a complement to traditional SEO rather than a replacement—running parallel optimization programs that address both legacy search behavior and emerging AI-first discovery patterns.
The Technical Foundation of AI Search Optimization
AI search optimization requires fundamentally different approaches than traditional SEO. Rather than optimizing for keyword rankings, AI SEO ensures brands appear in AI-generated responses through entity optimization, structured data, and conversational content that AI systems cite and trust.
Entity recognition and knowledge graphs. Establishing your brand as a recognized entity in knowledge graphs supports generative chatbot visibility. When Retrieval-Augmented Generation becomes standard, LLM systems interact with knowledge graphs to access factual information about your brand, leading to more accurate AI responses.
Semantic content architecture. AI platforms prioritize content that demonstrates clear entity relationships, comprehensive topic coverage, and authoritative expertise signals. Content must be designed for AI parsing and extraction, not just human readability.
E-E-A-T amplification. Named expert authors with verifiable credentials outperform anonymous content in AI citation. Original research and proprietary data create citation-worthy content that AI systems preferentially reference when synthesizing responses.
Multi-platform optimization. Each AI platform has distinct preferences. ChatGPT users seek confident, direct recommendations. Perplexity users conduct research and want cited sources with data transparency. Google AI Overviews pull from featured-snippet-style content. Winning across platforms requires content layers serving each system’s unique preferences.
Building Your AI Search Optimization Strategy
Organizations ready to capture the AI search opportunity should consider a structured approach that balances immediate wins with sustainable competitive advantage.
Audit current AI visibility. Before optimization, establish baseline measurements across ChatGPT, Perplexity, Gemini, and Google AI Overviews. Track how frequently your brand is cited, what queries trigger citations, and how you compare to competitors in AI-generated responses.
Prioritize high-intent queries. Focus initial optimization on queries that directly influence purchase decisions. Questions like “best [category] for [use case]” or “[competitor] vs [competitor] comparison” represent high-value citation opportunities that directly impact pipeline.
Restructure content for AI consumption. Evaluate existing content through an AI parsing lens. Does your content clearly answer specific questions? Are expert authors and their credentials visible? Is data structured for easy extraction? Content that performs well in traditional search may require significant restructuring for AI optimization.
Build authority signals systematically. AI platforms evaluate credibility through multiple signals: original research, expert authorship, backlinks from authoritative domains, and mentions in reputable sources. Develop a sustained program for building these trust signals across your digital footprint.
Integrate with broader go-to-market strategy. AI search optimization shouldn’t exist in isolation. Connect AI visibility efforts with brand awareness, content marketing, PR, and demand generation programs to create reinforcing effects across channels.
The Competitive Reality
The AI search optimization market is moving from early adoption to mainstream strategy. Companies that establish strong AI visibility now build defensive positioning that becomes increasingly difficult for competitors to overcome as AI platforms solidify their source preferences and citation patterns.
The data points toward a clear conclusion: B2B buyers have already changed their behavior, AI search platforms are scaling rapidly, and traditional organic traffic is declining permanently. Organizations that treat AI search optimization as a 2026 or 2027 initiative risk systematic exclusion from how their buyers discover, evaluate, and select vendors.
For B2B marketing leaders, CFOs evaluating channel investments, and CTOs assessing digital strategy, the question is no longer whether to optimize for AI search—it’s how quickly your organization can execute while the competitive window remains open.
