The AI search landscape has fundamentally shifted in just the first weeks of 2026. ChatGPT is introducing advertising. Google has made Gemini 3 the default model for AI Overviews worldwide. Click-through rates have collapsed by over 60% for queries where AI summaries appear. And AI agents are now completing transactions on behalf of users.
For law firms, these changes aren’t distant technology trends—they’re reshaping how potential clients discover and choose legal services right now.
The Biggest News: ChatGPT Is Introducing Advertising
On 16 January 2026, OpenAI made an announcement that sent shockwaves through the digital marketing industry: advertising is coming to ChatGPT.
This is a watershed moment. ChatGPT serves approximately 800 million weekly active users—making it one of the largest new advertising surfaces to emerge in digital history. For law firms, this creates an entirely new channel to reach potential clients at moments of genuine legal need.
How ChatGPT Advertising Will Work
Based on OpenAI’s announcements and early testing reports, here’s what we know:
Where Ads Will Appear: Ads will show at the bottom of ChatGPT’s answers when there’s a relevant sponsored product or service based on the current conversation. They’ll be clearly labelled as “sponsored” and separated from organic answers.
Targeting Method: Unlike Google’s keyword-based system, ChatGPT ads are contextually targeted based on conversation content. When someone discusses a legal issue—divorce proceedings, workplace injury, business disputes—relevant legal service ads could appear.
Pricing Model: According to Search Engine Land, OpenAI is using a pay-per-impression (PPM) model rather than pay-per-click. This means advertisers pay based on views, not clicks. Initial testing involves advertisers committing under $1 million each, with no self-serve buying tools available yet.
Who Will See Ads: Only free users and ChatGPT Go subscribers ($8/month) will see advertisements. Plus, Pro, Business, Enterprise, and Edu accounts will remain ad-free. This means the audience seeing ads will typically be more casual or cost-conscious users—though still potentially people with genuine legal needs.
Privacy Protections: OpenAI states it will keep conversations private from advertisers and never sell user data. Users can turn off personalisation and clear data used for ads at any time.
Why This Matters for Law Firms
The significance for law firm marketing cannot be overstated. Traditional search advertising captures intent at the moment someone types a query. ChatGPT advertising captures intent during a conversation—often a more detailed, nuanced expression of what someone actually needs.
Consider the difference: someone might type “divorce lawyer Sydney” into Google. But in ChatGPT, they might ask, “I’m thinking about leaving my husband, we have two kids and a house in the eastern suburbs, and he’s the main income earner—what should I know about divorce in Australia?”
That conversational context reveals far more about their situation and needs than any search query ever could. Advertisers with the opportunity to appear after such conversations are reaching people at genuinely high-intent moments.
However, the measurement challenges are significant. Unlike Google and Meta’s sophisticated attribution systems built over two decades, ChatGPT is launching with basic metrics only: total impressions and total clicks. No granular conversion tracking, no demographic insights, no purchase attribution yet.
As one agency executive told AdExchanger, advertisers are left with “more questions than answers at this point.” OpenAI has been “very noncommittal about everything” regarding details.
The Broader Implications
OpenAI’s move into advertising validates that AI-powered interfaces have become significant enough to warrant their own advertising ecosystems. As Mediaocean CMO Aaron Goldman noted, ads are realistically the only way for AI chatbots to scale globally and “realize their full potential.”
For Australian law firms, the practical advice is to monitor this space closely. When ChatGPT advertising expands beyond the initial US pilot—which will likely happen throughout 2026—firms that understand conversational advertising will have a significant advantage over those treating it like traditional search.
Google Gemini 3: The New Default for AI Search
On 27 January 2026, Google made Gemini 3 the default model powering AI Overviews globally. This wasn’t a minor technical update—it fundamentally changes how billions of people experience search.
What Changed
Previously, Google used a mix of models for AI Overviews, routing only complex questions to its most advanced systems. Now, Gemini 3—with its superior reasoning capabilities—powers all AI Overviews for everyone worldwide.
The upgrade also introduced seamless transitions into AI Mode. Users can now ask follow-up questions directly from an AI Overview and continue into a full conversational experience. Google’s VP of Product, Robby Stein, explained: “In our testing, we’ve found that people prefer an experience that flows naturally into a conversation—and that asking follow-up questions while keeping the context from AI Overviews makes Search more helpful.”
This creates what Blockchain Council analysis describes as a shift where “search is becoming a dialogue, not a list.”
The Impact on Traffic
The implications for website traffic are severe and well-documented. Seer Interactive’s September 2025 study analysed over 25 million impressions and found:
- Organic CTR dropped 61% for queries with AI Overviews, falling from 1.76% to just 0.61%
- Paid CTR crashed 68%, from 19.70% to 6.34%
- Even queries without AI Overviews saw organic CTR decline 41% year-over-year
These numbers represent a structural collapse of the click-based economy that has supported digital marketing since the early 2000s. When nearly two-thirds of your potential clicks vanish, that’s not an optimization problem—it’s an existential challenge.
Individual publishers have reported even more dramatic impacts. According to Search Engine Journal, The Daily Mail’s desktop CTR dropped from 25.23% to 2.79% when an AI Overview surfaced above a visible link—an 89% decline.
The Silver Lining: Citation Matters
However, there’s a critical counterbalancing finding: brands cited within AI Overviews actually see increased traffic compared to those not cited. The Seer Interactive research found:
- Brands cited in AI Overviews earned 35% more organic clicks
- Cited brands saw 91% higher paid CTR
- Being cited in an AI Overview can generate more qualified traffic than ranking #3 in traditional results
This fundamentally changes the SEO equation. The goal is no longer simply to rank #1 in organic results—it’s to become an authoritative source that AI systems cite when answering questions.
For law firms, this means your content strategy must shift from keyword optimisation to becoming the trusted source that AI pulls from when answering legal questions in your practice areas.
Google’s Personal Intelligence: Hyper-Personalised Search Arrives
On 22 January 2026, Google introduced Personal Intelligence—a feature that allows Google AI Pro and Ultra subscribers to connect Gmail and Google Photos to AI Mode in Search for deeply personalised results.
While currently limited to paid subscribers in the US, this signals Google’s direction toward search experiences tailored to individual circumstances.
What This Means in Practice
Imagine a potential client searching for a family lawyer. With Personal Intelligence enabled, Google could factor in:
- Information from their emails about divorce proceedings they’ve discussed
- Photos suggesting custody considerations (children’s ages, family situations)
- Calendar entries about related appointments
- Past search history on related topics
The AI could then provide recommendations tailored to their specific situation, not just generic results for “family lawyer Sydney.”
For law firms, this has profound implications. Generic website content that ranked well in traditional search may become less relevant when Google understands individual users’ contexts deeply. The firms that succeed will be those providing genuinely helpful, expert content that AI systems can draw upon for personalised recommendations.
Agentic Commerce: AI Agents Are Now Shopping
Perhaps the most forward-looking development is the rise of “agentic commerce”—AI agents that research, recommend, and even complete transactions on behalf of users.
Google’s Universal Commerce Protocol
In January 2026, Google unveiled the Universal Commerce Protocol (UCP), an open standard for agentic commerce developed with partners including Shopify, Etsy, Wayfair, Target, and Walmart. More than 20 additional companies have endorsed it, including Mastercard, Visa, Stripe, and American Express.
UCP enables shoppers to check out from eligible retailers directly within AI Mode in Search and the Gemini app. While initially focused on retail, the infrastructure being built could eventually extend to services—including legal consultations.
Google also introduced Business Agent, allowing shoppers to chat with brands directly on Search. Retailers including Lowe’s, Michael’s, and Reebok are live at launch. For law firms, similar branded AI assistants could eventually allow potential clients to ask initial questions and book consultations without leaving the search interface.
The AI Shopping Wars
Competition is intensifying rapidly. According to Modern Retail, 2026 is shaping up as a pivotal year for agentic commerce:
- Amazon released “Buy For Me,” an agentic tool letting consumers shop other websites without leaving Amazon’s app
- OpenAI has embedded checkout directly into ChatGPT through partnerships with Target, Instacart, and DoorDash
- Perplexity has an AI shopping agent (Comet) that can automatically place orders on e-commerce sites
The legal implications are already being tested. Amazon has sued Perplexity over Comet, alleging it disguised automated browsing as human activity. Perplexity’s defence? That Amazon’s central concern is its inability to sell products through ads if AI agents use the platform—because “AI agents don’t have eyeballs to see the pervasive advertising Amazon bombards its users with.”
This tension between AI agents and advertising-supported platforms will shape how commerce evolves. For law firms, the question becomes: will AI agents eventually research, recommend, and book legal consultations on behalf of users?
The Traffic Reality: What the Latest Data Shows
The latest research paints a challenging picture for traditional website traffic strategies.
Zero-Click Searches Dominate
According to multiple studies cited in Search Engine Journal’s analysis, zero-click searches now make up 69% of all queries—up from 56% just 18 months ago. AI Overviews are a major driver of this increase.
Industry-Specific Impacts
The March 2025 core update showed dramatic AI Overview growth in specific verticals:
- Entertainment: 528% increase in AI Overview presence
- Restaurants: 387% increase
- Travel: 381% increase
Healthcare and legal queries already had high AI Overview presence before this surge, meaning law firms have been experiencing these impacts for longer than many industries.
The Quality Paradox
Here’s where it gets interesting. While total traffic volume is declining, the traffic that does come through appears more valuable. Research from Semrush reveals that the average visitor from an AI platform is worth 4.4 times more than the average traditional organic search visitor, based on conversion rates.
AI traffic has surged by 527% year-over-year between January and May 2025. While still representing a small portion of overall traffic, the rapid growth trajectory suggests firms should be positioning themselves now.
Additionally, when ChatGPT cites webpages, approximately 90% of cited pages rank in traditional organic search positions 21 or lower. This means you don’t necessarily need top-three rankings to gain AI visibility—you need content that provides clear, specific, trustworthy answers.
What This Means for Your Law Firm’s Marketing
Given these developments, Australian law firms need to fundamentally rethink their approach to digital visibility.
Shift from Keywords to Authority
Modern AI search has evolved from keyword matching to entity-based understanding. Search engines and AI systems now focus on understanding who your law firm is as an entity and the relationships around that entity.
This means your online presence needs to clearly establish who you are, what you do, and why you’re authoritative in your practice areas. It’s less about keyword density and more about building a coherent, consistent brand presence that AI systems can understand and trust.
The importance of brand authority has never been greater. AI systems are increasingly sophisticated at understanding brand signals across the entire internet—synthesising information from reviews, news mentions, social media, directory listings, legal publications, and countless other sources.
Create Content for AI Citation
The content that performs well in AI search has specific characteristics:
Answer questions directly. Rather than building up through lengthy introductions, provide clear, direct answers early, then elaborate with supporting detail. AI systems favour content that immediately addresses user intent.
Use question-and-answer formats. FAQ sections, structured Q&A content, and content explicitly addressing common client questions are more likely to be cited. Think about the questions potential clients ask during initial consultations.
Structure information clearly. Tables, bullet points, and well-organised content help AI systems extract and present information accurately. When presenting comparative information, use structured formats rather than prose paragraphs.
Provide original insights. AI systems are flooded with generic content. Material providing genuine expertise, original analysis, or unique perspectives is more likely to be cited. Share genuine insights about legal processes, common client mistakes, or practice-area trends.
For detailed guidance, explore content strategy approaches for law firms.
Invest in Video
Video content is increasingly important for AI visibility. YouTube content specifically matters for Google AI visibility. Creating educational videos answering common legal questions positions your firm favourably in AI results while building trust with human viewers.
Manage Your Reputation Across Platforms
Reviews have always mattered for law firms, but their role in AI search is evolving. AI systems analyse review content—not just star ratings—to understand sentiment about businesses.
When someone asks an AI system about a law firm’s expertise in a particular area, the AI may pull directly from review content to formulate its answer. The substance of your reviews matters as much as the overall rating.
Research suggests AI systems pull review content from platforms like Yelp and Glassdoor, not just Google Business Profile reviews. For comprehensive reputation management, review your approach to getting more Google reviews while ensuring presence on platforms that matter for AI visibility.
Rethink Your Paid Advertising Strategy
With ChatGPT introducing ads and Google evolving its AI-based advertising, the paid landscape is shifting significantly.
Traditional Google Ads strategies remain important but need adjustment for the AI era. When paid CTR has dropped 68% on AI Overview queries, continuing the same approach won’t deliver the same results.
Consider:
- Monitor ChatGPT advertising as it expands beyond the initial pilot
- Focus paid spend on transactional queries where AI Overviews are less prevalent
- Invest in brand building so you’re more likely to be cited in AI answers
- Track share of voice in AI responses, not just traditional rankings

Practical Action Steps for February 2026
Here’s what law firms should do right now:
1. Audit Your AI Visibility
Search for your practice areas and locations in ChatGPT, Google Gemini, and Perplexity. What do these systems say about you? What do they say about your competitors? Are there inaccuracies about your firm that need correcting?
This baseline assessment reveals where you stand and where improvement is needed.
2. Restructure Key Content for AI Citation
Review your highest-value website pages. Do they directly answer common client questions? Are they structured for easy AI extraction? Start with your main practice area pages and reshape them to provide clear, authoritative answers that AI systems can cite.
3. Strengthen Your Brand Presence Everywhere
Ensure consistent, accurate information across all major platforms—Google Business Profile, Yelp, legal directories, LinkedIn, and social media. AI systems synthesise information from multiple sources; inconsistency creates confusion and reduces your authority.
4. Create Video Content
Even simple educational videos answering common legal questions can improve your firm’s presence in AI results. Start with the questions clients most frequently ask during consultations.
5. Prepare for Conversational Advertising
While ChatGPT advertising is initially limited to the US, it will expand. Understanding how conversational advertising differs from traditional search advertising positions your firm for when these opportunities reach Australia.
6. Review Your Overall Marketing Strategy
These AI changes should be integrated into your broader marketing approach, not treated as a separate initiative. Ensure your website and social media presence support AI visibility alongside traditional channels.
Looking Ahead: What to Expect
Based on current trajectories, expect these developments in the coming months:
AI Mode will become the primary search interface. Google is already transitioning users toward AI-driven experiences. Gemini 3 as the global default is just the beginning.
ChatGPT advertising will expand. Following the US pilot, expect geographic expansion and broader advertiser access throughout 2026. Self-serve advertising tools will likely follow.
Agentic commerce will reach services. The infrastructure enabling AI agents to complete retail transactions will extend to service bookings—potentially including legal consultations.
Measurement will improve. Both Google and OpenAI will develop better attribution systems as advertisers demand accountability. Firms testing early will have data advantages.
Brand authority will matter more than ever. As AI systems become more sophisticated at evaluating trustworthiness, firms that have invested in genuine brand building will be increasingly favoured.
Conclusion
The first weeks of 2026 have brought more significant changes to search than the previous several years combined. ChatGPT introducing advertising, Gemini 3 becoming the global default for AI Overviews, and the rise of agentic commerce represent a fundamental transformation in how potential clients discover legal services.
For Australian law firms, the message is clear: adapt now or risk becoming invisible in AI-mediated discovery.
The fundamentals of good marketing haven’t changed. Building a strong brand, creating genuinely helpful content, maintaining consistent accurate information, and serving clients exceptionally well remain essential. What has changed is the context in which these fundamentals operate.
AI systems are now the intermediaries between potential clients and law firms. Your practice’s success increasingly depends on how these systems perceive and represent you. Take control of your narrative now, before your competitors do.
