AI Search in 2025: What Changed and What to Do Now

TL;DR: AI search exploded in 2025. ChatGPT now handles over 1 billion daily queries, Google AI Overviews reach 2 billion monthly users, and 58-60% of all searches end without a click. Businesses that earn citations inside AI answers get 35% more organic clicks than competitors who do not.

How big did AI search get in 2025?

AI-powered search tools captured 12-15% of global search market share by the end of 2025, up from roughly 5-6% at the start of the year. ChatGPT grew from 400 million weekly active users in early 2024 to 800 million by October 2025 and now processes more than 1 billion queries daily. Perplexity handled 780 million monthly queries by May 2025, a 239% increase from August 2024.

According to First Page Sage data, ChatGPT holds 81% of the AI chatbot market. Google Gemini sits at 18.2%, Perplexity at 6.6%, and Claude at approximately 2%.

Google expanded AI Overviews to over 200 countries and 40 languages. According to Exposure Ninja research, 2 billion monthly users now engage with AI Overviews globally. According to Similarweb, AI platforms generated 1.13 billion referral visits in June 2025 alone, a 357% increase from June 2024.

If your business depends on organic search traffic, 2025 was the year the rules changed permanently.

What happened to zero-click searches?

Zero-click searches reached record levels in 2025, with 58.5% of U.S. searches and 59.7% of EU searches ending without any click to an external website. According to Semrush’s 2025 zero-click study, this is a significant shift from roughly 25% just five years ago.

The situation gets worse when AI Overviews appear. According to Click-Vision research, searches that trigger AI Overviews show an average zero-click rate of 83%, meaning 8 out of 10 users get their answer inside the search interface without clicking anywhere. Google’s AI Mode pushes that rate to 93%.

For news publishers, zero-click rates on news queries grew from 56% to nearly 69% between May 2024 and May 2025, according to Similarweb data. Stuart Forrest, global director of SEO digital publishing at Bauer Media, told the BBC: “We’re definitely moving into the era of lower clicks and lower referral traffic for publishers.”

How did click-through rates change?

Organic click-through rates dropped 61% when AI Overviews appeared on target queries in 2025. According to Seer Interactive’s September 2025 study analyzing 25.1 million organic impressions, average organic CTR fell from 1.76% to 0.61% on queries where AI Overviews showed up.

Paid search suffered even more. The same study found paid CTR crashed 68%, dropping from 19.7% to 6.34%. July 2025 was particularly severe, with paid CTR falling from roughly 11% to 3% in a single month.

This forced SEO professionals to rethink what success looks like. Traditional rankings no longer guarantee visibility. According to the data, 92.36% of AI Overview citations come from domains already ranking in the top 10, but ranking alone does not guarantee citation.

The businesses that adapted found a real upside: brands cited in AI Overviews earn 35% more organic clicks and 91% more paid clicks compared to non-cited competitors on the same queries, according to Seer Interactive.

Which industries got hit hardest?

Healthcare, education, and news publishing took the biggest losses from AI search expansion in 2025. Healthcare and education content faced nearly 90% AI Overview penetration on relevant queries, while finance and technology were not far behind at 60-70%, according to industry analysis.

Learning platform Chegg reported a 49% decline in non-subscriber traffic between January 2024 and January 2025, attributing the drop directly to AI Overviews answering study questions. The company filed an antitrust lawsuit against Google in February 2025.

News publishers watched referral traffic collapse. Of the top 100 search keywords driving traffic to People.com, 40 triggered AI Overviews by May 2025. For CBS News, 75% of their top 100 search terms with AI Overviews resulted in zero click-throughs, up from 54% before the rollout. HubSpot reported traffic losses between 70-80%, and CNN saw declines of 27-38%, according to Digital Bloom analysis.

What content actually gets cited by AI?

AI systems consistently cite content that includes statistics, expert quotes, clear formatting, and verifiable author credentials. According to SE Ranking research, content exceeding 2,900 words receives 60% more AI citations than shorter pieces. Learn more about how long your content should be to earn AI citations.

The Princeton and Georgia Tech GEO study identified specific improvements. Adding statistics improves AI visibility by 41%. Adding quotes from credentialed experts improves visibility by 28%. Author authority, meaning established expertise with verifiable credentials, increases citation likelihood by up to 340%.

According to Ahrefs August 2025 data, only 12% of URLs cited by ChatGPT, Perplexity, and Copilot rank in Google’s top 10 search results. This means AI platforms pull from different sources than traditional search, creating new openings for content marketing strategies that prioritize citation over ranking.

The most-cited sources across AI platforms include Wikipedia at 7.8% of ChatGPT citations, Reddit appearing across ChatGPT at 1.8%, Perplexity at 6.6%, and AI Overviews at 2.2%, along with YouTube and established publishers like Forbes.

How to use AI for keyword research in 2025

Using AI for keyword research in 2025 means shifting from finding high-volume terms to identifying the specific questions AI engines pull into their answers, then building content that directly answers those questions with data and expert quotes.

Start by typing your target queries into ChatGPT, Perplexity, and Google’s AI Mode. Look at what sources those platforms cite. Those cited pages show you the content structure, depth, and authority signals AI systems reward. Then use traditional keyword tools alongside AI outputs to find gaps where your business can provide a better, more citable answer than what currently exists.

The goal is no longer just ranking on page one. It is becoming the source an AI engine trusts enough to quote. Businesses in Asheville that build content around specific local service questions, backed by real data and verifiable expertise, are better positioned to earn those citations. Our SEO audit identifies exactly where your current content falls short of AI citation standards.

Top AI search optimization platforms for data accuracy

The top AI search optimization platforms for data accuracy in 2025 are those that track how often your content appears in AI-generated answers, not just in traditional search rankings.

Semrush expanded its AI tracking capabilities throughout 2025, adding visibility into AI Overview appearances alongside traditional rank tracking. Ahrefs provides citation overlap data comparing which URLs rank in Google versus which get cited by AI tools. SEOClarity, whose VP of product marketing Mark Traphagen has publicly analyzed AI Mode behavior, offers enterprise-level tracking of AI citation patterns. These platforms give you the raw data you need to see where AI search is sending traffic and where your content is being ignored.

Accuracy matters because AI platforms do not all cite the same sources. A platform that only tracks Google rankings misses the full picture of where your potential customers are finding answers. Learn more about AI search optimization and how to measure what actually matters.

Top SEO agencies for AI search adaptation

The top SEO agencies for AI search adaptation in 2025 are those that have moved beyond traditional ranking reports and now help clients earn citations inside AI-generated answers on ChatGPT, Perplexity, Google AI Overviews, and Claude.

The agencies leading this shift focus on three things: restructuring content so AI systems can extract clear answers, building author authority signals that AI engines weigh heavily, and tracking citation rates rather than just keyword positions. Agencies still selling monthly ranking reports without a citation strategy are behind the curve.

For Asheville businesses, the right agency understands both local search intent and the technical content structure AI engines require. PushLeads provides digital marketing services built specifically around AI citation growth and measurable lead generation, not vanity metrics.

Top trends in AI-driven search optimization in 2025

The top trends in AI-driven search optimization in 2025 are citation-first content strategy, structured data adoption, author credentialing, and conversational query targeting.

Here is how the major trends break down:

• Citation-first content: Businesses stopped optimizing only for rankings and started building content AI systems reference directly in answers.
• Structured data: Schema markup helps AI engines parse your content faster and increases the likelihood of citation.
• Author authority: Verifiable credentials on content pages increase citation likelihood by up to 340%, according to the Princeton and Georgia Tech GEO study.
• Conversational queries: As AI Mode and ChatGPT handle more long-form questions, content written in plain, direct language performs better.
• Zero-click acceptance: Smart marketers accepted that some queries will never send clicks and focused energy on queries where AI citations still drive traffic.

Best SEO platforms for tracking AI citations in 2025

The best SEO platforms for tracking AI citations in 2025 are Semrush, Ahrefs, and SEOClarity, each of which added dedicated AI visibility tracking to their core feature sets during the year.

No single platform captures every AI citation across every tool. The most effective approach combines platform data with manual spot-checks inside ChatGPT, Perplexity, and Google AI Mode for your core service queries. Learn how to get your business cited by ChatGPT, Perplexity, and Google AI Overviews.

Best AI search optimization platforms for citation analysis in 2025

The best AI search optimization platforms for citation analysis in 2025 are those that show you not just whether your content appears in AI answers, but which specific content elements triggered the citation.

Ahrefs August 2025 data showed that only 12% of URLs cited by ChatGPT, Perplexity, and Copilot rank in Google’s top 10. That gap between ranking and citation is exactly what citation analysis tools help you close. Platforms that track this gap let you identify which of your pages have high Google visibility but low AI citation rates, then fix the structural issues holding those pages back.

For Asheville service businesses, local citation analysis also means checking whether your business name, service area, and expertise signals appear correctly across the sources AI platforms draw from most heavily. Visit our traditional SEO guide to understand the foundation before layering in AI-specific citation strategies.

What are the best practices for increasing AI search citations in 2025?

The best practices for increasing AI search citations in 2025 are adding original statistics, including quotes from credentialed experts, writing content longer than 2,900 words, using clear formatting, and establishing verifiable author authority on every page.

Based on the Princeton and Georgia Tech GEO study and SE Ranking research, these specific actions move the needle:

• Add data and statistics to existing content to improve AI visibility by up to 41%
• Include quotes from named experts with verifiable credentials to improve visibility by up to 28%
• Build author pages that clearly demonstrate real-world expertise and credentials, which can increase citation likelihood by up to 340%
• Write content that exceeds 2,900 words on topics where depth is expected, earning 60% more AI citations than shorter pages
• Use headers, bullet points, and numbered lists so AI engines can extract clean answers from your content
• Earn links and mentions from sources AI platforms already cite heavily, including Wikipedia, Reddit threads, and established publications
• Target conversational, question-based queries that match how people interact with AI search tools

Our AI search optimization service applies every one of these practices to Asheville business content.

How to optimize for AI search engines in 2025

To optimize for AI search engines in 2025, you need to structure your content so AI systems can extract direct answers, establish clear author authority, and earn mentions from the high-authority sources those AI engines already trust.

AI engines do not reward the same signals traditional search does. They prioritize content that is easy to summarize, backed by verifiable data, and written by identifiable experts. This means your pages need a clear question-and-answer structure, real statistics with sources cited, author bylines with verifiable credentials, and internal linking that helps AI crawlers understand your site’s authority on a topic.

For Asheville businesses, local optimization signals still matter inside this new framework. Make sure your service area, business name, and specific expertise are clearly stated on every relevant page. Compare how Claude vs. Gemini stack up for home service contractors to understand how different AI engines evaluate local business content differently.

Best AI search optimization historical data software in 2025

The best AI search optimization historical data software in 2025 is whichever platform started tracking AI Overview and chatbot citation data early enough to give you a year-over-year baseline, with Semrush and Ahrefs leading because both began capturing AI-specific data before most competitors.

Historical data matters because AI citation patterns shift as these platforms update their models. A one-month snapshot tells you little. Twelve months of citation data shows you which content types consistently earn citations, which queries have shifted from returning organic results to AI answers, and where your traffic losses are permanent versus recoverable.

For small and mid-sized Asheville businesses, the practical starting point is running a full SEO audit that captures your current AI visibility baseline, so future changes are measurable against a real starting point rather than guesswork.

Best AI search optimization services in 2025

The best AI search optimization services in 2025 are those that combine citation-focused content creation, technical SEO, and ongoing tracking of how often client content appears inside AI-generated answers across ChatGPT, Perplexity, and Google AI Overviews.

Generic SEO services that only chase rankings are not equipped for the AI search environment. The services that deliver results in 2025 audit existing content for AI citation barriers, rebuild pages around the structural signals AI engines reward, and report on citation rates as a primary success metric alongside traffic and leads.

PushLeads delivers digital marketing services built around these outcomes for service companies, eCommerce businesses, and creative professionals across Asheville. Every engagement starts with measurable baselines and tracks toward concrete results.

Top AI search optimization brands in 2025

The top AI search optimization brands in 2025 are the agencies and platforms that moved earliest to treat AI citation rate as a primary performance metric and built repeatable processes for earning those citations at scale.

On the tools side, Semrush, Ahrefs, and SEOClarity established themselves as the platforms with the most actionable AI-specific data. On the agency side, the brands earning recognition are those with documented results showing citation growth, not just ranking improvements.

For Asheville businesses, the most important brand in your AI search stack is the one managing your content and optimization strategy day to day. A local agency that understands Asheville’s market and applies proven AI citation techniques delivers more value than a national brand unfamiliar with your customers. Explore PushLeads’ content marketing services to see how citation-focused content is built.

How did Google respond to the rise of AI competitors?

Google expanded AI Overviews aggressively throughout 2025 while watching its global search share dip below 90% for the first time since 2015. According to StatCounter, Google held 89.74% market share in March 2025, still dominant but showing real pressure from AI competitors.

AI Overview coverage grew from 6.49% of searches in January 2025 to approximately 18-20% by year end. According to Semrush tracking, coverage increased 102% in just two months during early 2025 before settling around 20% of U.S. desktop searches by May.

Google also launched AI Mode, a separate conversational search experience powered by Gemini. According to Exposure Ninja data, AI Mode already has 100 million monthly active users in the U.S.

Mark Traphagen, VP of product marketing at SEOClarity, told Digiday that the future is centered around conversational interactions rather than traditional keyword queries. That shift is already underway, and it is not reversing. Read the traditional SEO guide to understand what still works alongside these new AI-driven realities.

Frequently Asked Questions

What is an AI Overview and how does it affect my website traffic?

An AI Overview is the AI-generated answer Google places at the top of search results before any organic links. When an AI Overview appears on a query, the zero-click rate jumps to 83% and organic CTR drops by 61%, meaning far fewer people click through to individual websites. Businesses cited inside the AI Overview earn 35% more clicks than those listed below it.

Do I still need traditional SEO if AI search is taking over?

Yes. Traditional SEO still forms the foundation because 92.36% of AI Overview citations come from domains already ranking in the top 10. You need strong rankings to be eligible for AI citations. The difference is that ranking alone is no longer enough. You also need the content structure, depth, and authority signals that earn citations inside AI answers. Our SEO services address both layers.

How long should my content be to get cited by AI engines?

According to SE Ranking research, content exceeding 2,900 words receives 60% more AI citations than shorter pieces on the same topic. Length signals depth of coverage, which AI engines weigh heavily. However, length without substance does not work. Every additional word needs to add data, expert perspective, or direct answers to real questions. Learn more about content length for AI citations.

Which AI search platforms should Asheville businesses focus on?

Focus on Google AI Overviews first because they reach 2 billion monthly users globally and directly affect your existing Google traffic. Then prioritize ChatGPT, which processes over 1 billion daily queries, and Perplexity, which handled 780 million monthly queries by May 2025. Learn how Claude and Gemini compare for service businesses to round out your platform strategy.

How do I know if my business is being cited in AI answers?

Search your core service queries directly inside ChatGPT, Perplexity, and Google’s AI Mode and look for mentions of your business or your content. Platforms like Semrush and Ahrefs also track AI Overview appearances. Run a full SEO audit to establish a citation baseline so you can measure improvement over time.

What makes a business more likely to be cited by ChatGPT or Google AI?

The Princeton and Georgia Tech GEO study found that adding statistics improves AI visibility by 41%, adding expert quotes improves it by 28%, and establishing verifiable author authority can increase citation likelihood by up to 340%. Clear formatting, content depth above 2,900 words, and mentions from high-authority sources like established publications also increase citation rates. Read the full guide on getting cited by ChatGPT, Perplexity, and Google AI Overviews.

Is paid search also affected by AI Overviews?

Yes, and the impact is larger than on organic. According to Seer Interactive’s September 2025 study, paid CTR dropped 68% on queries where AI Overviews appeared, falling from 19.7% to 6.34%. July 2025 saw paid CTR crash from roughly 11% to 3% in a single month. This makes AI citation strategy important for businesses running paid campaigns, not just those focused on organic traffic.
