AI Overviews vs AI Mode: What Australian Law Firms Need to Know

Google no longer delivers search results through a single system. Instead, it now runs two parallel AI experiences that determine whether potential clients discover your law firm online: AI Overviews and AI Mode.

If you’ve noticed changes in how your firm appears in search results—or wondered why your website traffic has shifted—these two AI systems are likely responsible. But here’s what most law firm principals don’t realise: being visible in one doesn’t guarantee visibility in the other.

Recent research analysing over 730,000 search response pairs reveals something unexpected. AI Overviews and AI Mode reach remarkably similar conclusions about what to tell searchers—yet they cite completely different sources to support those answers. This has profound implications for how your firm should approach digital marketing in 2025 and beyond.

In this guide, we’ll break down exactly how these two systems work, what the data shows about their differences, and what your law firm should do to maintain visibility across both. No technical jargon required—just practical insights you can act on.

Understanding the Basics: What Are AI Overviews and AI Mode?

Before diving into the data, let’s clarify what we’re actually dealing with. These are two distinct features that Google has rolled out, and they serve different purposes for searchers.

What Are AI Overviews?

AI Overviews are automatically generated summaries that appear at the top of traditional search results for certain queries. Think of them as Google’s “quick notes” feature—instead of showing you a list of ten blue links, Google now often displays a synthesised answer first.

When someone searches “how to contest a will in Victoria,” Google’s AI might generate a summary explaining the basic process, time limits, and key considerations. This summary appears before any organic search results, often pushing traditional website listings further down the page.

According to TechCrunch’s reporting on Google’s Q2 2025 earnings call, AI Overviews now reach 2 billion monthly users globally—up from 1.5 billion in May 2025. For Australian searches, these summaries appear in roughly 16% of desktop searches, with informational queries triggering them most frequently.

Key characteristics of AI Overviews include static summaries with no back-and-forth conversation, shorter responses averaging around 50 words, and availability across 200+ countries and 40+ languages.

What Is AI Mode?

AI Mode is Google’s interactive, conversational search experience. Rather than typing a query and scanning results, users can engage in an ongoing conversation with Google’s AI, asking follow-up questions and refining their search in real time.

Picture a potential client typing “I think my employer underpaid me”—in AI Mode, they could then ask “what evidence do I need?” followed by “how long do I have to make a claim?” without starting a new search each time.

Google reports AI Mode has over 100 million monthly active users, primarily in the United States and India, with broader rollout continuing. Its responses are substantially longer—averaging around 300 words compared to AI Overview’s 50 words—and the feature triggers on virtually every query where it’s available.

Understanding the distinction between these systems is essential because the future of SEO for law firms increasingly depends on appearing in AI-generated responses, not just traditional search rankings.

The Surprising Research: Same Answers, Different Sources

The most significant finding from recent industry research challenges a common assumption. Many marketers believed AI Mode simply expanded on AI Overview answers—taking the same sources and adding more detail. The data tells a different story.

Citation Overlap Is Remarkably Low

When researchers analysed 540,000 query pairs comparing AI Overviews and AI Mode responses, they found that cited URLs overlapped just 13.7% of the time. Put another way, 87% of the time, these two systems pull from completely different sources to answer the same question.

This isn’t a minor technical detail. If your law firm’s website appears in an AI Overview for “family lawyer Melbourne,” there’s no guarantee it will appear when someone asks the same question in AI Mode. You might be visible in one system and completely absent from the other.

Different Words, Same Meaning

Here’s where things get interesting. Despite citing different sources and using different language, AI Overviews and AI Mode agree on what to say approximately 86% of the time. Their semantic similarity—the underlying meaning of their responses—is remarkably consistent.

Word-level overlap between the two systems measures just 16%. They start with the same first sentence only 2.51% of the time and produce identical responses in merely 0.51% of cases.

This pattern suggests something important: Google’s AI systems have developed a consistent understanding of topics across the web. They agree on the substantive answer but arrive at it through different paths, consulting different sources along the way.

For law firms, this means you can’t optimise for one AI system and expect automatic success in the other. Both systems need attention, and the strategies for each may differ. This is precisely why understanding SEO versus GEO for law firms has become essential.

Source Preferences Differ Substantially

The research revealed distinct patterns in which sources each system prefers:

AI Overviews appear to favour video content and community platforms, while AI Mode leans more heavily on encyclopaedic sources and detailed reference material. Both systems overwhelmingly prefer article-format content over other formats.

What the Numbers Mean for Your Law Firm’s Visibility

Understanding abstract statistics is one thing. Translating them into practical implications for your practice is another. Let’s examine what these findings mean in concrete terms.

The Traffic Impact Is Real

According to WordStream’s analysis of AI Overview statistics, users are nearly 47% less likely to click a traditional search result when an AI Overview appears. Only 8% of visits result in a click when an AI summary is shown, compared to 15% without one.

For law firms, this represents a significant shift. If you’ve invested in SEO strategy that achieved strong organic rankings, you may find that traffic no longer follows those rankings as reliably as before. The AI summary often resolves the searcher’s immediate question, reducing the need to click through to your website.

This doesn’t mean SEO is dead—far from it. But it does mean the goal has evolved. Being cited within AI responses now matters as much as, or more than, ranking in traditional results.

Brand Mentions Follow Different Rules

AI Mode responses include 2.5 times more brand and entity mentions than AI Overviews. When AI Mode answers a query, it names more law firms, legal resources, and specific practitioners than the shorter AI Overview format.

However, there’s an important correlation: if your firm is mentioned in an AI Overview, there’s a 61% chance it will also appear in AI Mode’s longer response. The systems appear to share a foundation of “important entities” for any given topic, even while citing different supporting sources.

The implication? Getting mentioned in AI Overviews may create a pathway to AI Mode visibility. But you’ll face more competition in AI Mode, sharing space with additional firms that didn’t make the shorter AI Overview cut.

Many Responses Include No Brands At All

Here’s a sobering statistic: 59.41% of AI Overview responses and 34.66% of AI Mode responses contain no brand or firm mentions whatsoever. Nearly one-third of all AI responses across both systems mention no businesses at all.

These tend to be purely informational queries where no brand is expected—questions like “what is the limitation period for personal injury claims” or “how does the Family Court work.” The AI answers the question without pointing users toward any specific firm.

This creates both a challenge and an opportunity. For generic informational queries, getting mentioned is difficult. But for queries with commercial intent—where someone is actively seeking legal help—being among the few firms mentioned becomes incredibly valuable.

How AI Systems Are Reshaping Client Acquisition

The implications of these changes extend beyond visibility metrics. They’re fundamentally altering how potential clients find and choose law firms.

The Zero-Click Reality

According to DemandSage’s analysis of AI Overview statistics, users are more likely to end their search session after seeing an AI Overview, with sessions ending 26% of the time compared to 16% for standard results pages without AI summaries.

This “zero-click” phenomenon means many searchers get their answer without visiting any website. For informational queries, this might be acceptable—you wouldn’t expect every search about court procedures to generate a client inquiry.

But when AI summaries begin answering queries with purchase intent—questions from people ready to hire a lawyer—the firm mentioned in that summary gains a significant advantage over competitors whose websites the searcher never visits.

Understanding this shift is critical. As we’ve explored in our analysis of whether AI search is stealing your law firm’s organic traffic, the solution isn’t to fight against AI but to position your firm within it.

Longer Queries, Different Intent

Search Engine Land’s research found that impressions and clicks increased for search terms with 3-4 words, held steady for terms with 7+ words, and dropped by about 11% for search terms with just 1-2 words.

This aligns with AI Mode’s conversational nature. Users are typing fuller, more specific questions rather than short keywords. Someone might previously have searched “divorce lawyer Sydney” but now types “how do I find a divorce lawyer in Sydney who handles complex property settlements.”

For law firms, this shift toward longer, more specific queries creates opportunities. You can create content addressing these nuanced questions—content that AI systems can then cite when generating their responses.

Trust Remains Complex

A Digital Third Coast survey found that 47% of users have made a purchase because an AI Overview referenced it. Yet 68% still fact-check information from AI responses, suggesting trust is building but not absolute.

For legal services—where the stakes are high and clients need confidence in their choice—this dual reality matters. Potential clients may discover your firm through AI, but they’ll likely still visit your website to verify your credentials, read reviews, and assess whether you’re the right fit.

This means your website’s quality, your Google reviews, and your overall digital presence remain crucial even as AI becomes the primary discovery mechanism.

Practical Steps: How Your Law Firm Should Respond

Understanding the landscape is valuable, but action creates results. Here are concrete steps your firm should take to maintain and improve visibility across both AI search experiences.

Track Your AI Visibility Separately

With only 13.7% source overlap between AI Overviews and AI Mode, being cited in one doesn’t guarantee visibility in the other. You need to monitor both.

Start by regularly searching for terms your potential clients use and noting whether your firm appears in AI responses. Track this over time. Consider using AI monitoring tools designed for law firms to automate this process and identify trends.

This separate tracking will reveal whether you have gaps in one system or the other, allowing you to adjust your strategy accordingly.

Build Topical Authority, Not Just Keyword Rankings

The 86% semantic similarity between AI Overviews and AI Mode responses tells us something important: both systems look for the same themes and concepts, just expressed differently.

Rather than targeting specific phrases, focus on building comprehensive coverage of your practice areas. If you specialise in employment law, create content that thoroughly addresses wrongful dismissal, workplace discrimination, unfair dismissal claims, redundancy rights, and related topics.

This topical authority signals to AI systems that your firm is a relevant source on employment law matters—not because you’ve stuffed keywords, but because you’ve demonstrated genuine expertise across the subject area.

This approach aligns with what research from marketing scholars like Jenni Romaniuk has shown about brand building: consistency and comprehensive presence matter more than clever campaigns.

Create Content for Different Formats

AI Overviews prefer video content and cite YouTube more frequently than AI Mode does. AI Mode, conversely, draws more heavily from detailed written resources and encyclopaedic content.

Your content strategy should account for both. Invest in video marketing for your law firm to increase AI Overview visibility, while also publishing comprehensive written guides that AI Mode can reference.

A balanced approach might include short explainer videos on common legal questions (targeting AI Overviews), detailed written guides expanding on those same topics (targeting AI Mode), and FAQ pages that address specific questions in concise, citable formats.

Optimise for Citation, Not Just Traffic

Traditional SEO focused on getting clicks to your website. AI optimisation requires a mindset shift—you want to be cited, even if that citation doesn’t always generate a click.

Being mentioned as a trusted source in an AI response builds brand awareness and credibility, even among searchers who don’t immediately visit your site. Over time, these impressions compound. When someone later searches with clearer intent to hire, your firm’s name will feel familiar.

This is similar to how brand strategy for law firms has always worked: consistent presence builds recognition, which eventually converts to business.

Consider the Competitive Landscape

If you’re mentioned in an AI Overview, you have a 61% chance of appearing in AI Mode too—but alongside additional competitors who didn’t make the shorter AI Overview cut.

This means your competitive set changes depending on which AI system responds. In AI Overviews, you might compete against three other firms; in AI Mode, that might expand to seven or eight.

Understanding who your AI competitors are—which may differ from your traditional organic search competitors—helps you identify where to focus differentiation efforts.

Invest in Encyclopaedic Content

Wikipedia appears in nearly 29% of AI Mode citations compared to 18% in AI Overviews. This preference for encyclopaedic, comprehensive content suggests a clear direction for your content strategy.

Create content that serves as a comprehensive reference on topics within your practice areas. Rather than thin blog posts covering surface-level information, develop resources that thoroughly explain concepts, include relevant statistics and citations, and provide genuine value.

This type of content is more likely to be cited by AI systems seeking authoritative sources to support their responses.

Understanding GEO: The New Framework for AI Visibility

These changes have given rise to a new discipline: Generative Engine Optimisation, or GEO. While traditional SEO focused on ranking in search results, GEO focuses on appearing in AI-generated responses.

How GEO Differs from Traditional SEO

Traditional SEO primarily concerned itself with technical factors like site speed, mobile-friendliness, and backlink profiles, alongside content relevance for specific keywords. GEO shares some foundations with SEO but adds new considerations.

GEO priorities include how AI systems can extract and cite your content, whether your firm is recognised as an authority in its field, how your brand is discussed across the web (not just on your own site), and whether your content directly answers the questions AI systems receive.

The strategic positioning required in the age of AI involves both traditional SEO foundations and these newer GEO considerations.

Why Both SEO and GEO Matter

Some law firm principals ask whether they should abandon SEO in favour of GEO. The answer is no—you need both.

Traditional organic results still appear below AI summaries, and many searchers scroll past AI responses to find specific websites. A strong SEO foundation supports GEO success, since AI systems often pull from high-authority sites that have built their credibility through SEO best practices.

Think of SEO and GEO as complementary strategies. SEO builds the foundation of your digital presence; GEO ensures that presence translates into AI visibility.

Our comprehensive comparison of SEO versus GEO for law firms explores this relationship in greater detail.

The Broader Context: Why This Change Was Inevitable

Google’s shift toward AI-generated responses wasn’t arbitrary. It reflects fundamental changes in how people search and what they expect from search engines.

User Behaviour Has Changed

Modern searchers don’t want to wade through ten blue links to find an answer. They want direct responses to their questions. AI Overviews and AI Mode deliver on this expectation by synthesising information and presenting it conversationally.

For legal queries, this evolution makes sense. Someone searching “what happens if I die without a will in NSW” doesn’t necessarily want to read five different law firm blog posts. They want a clear, accurate answer—which AI can now provide.

Competition from Alternative Platforms

Google faces increasing competition from AI-native platforms like ChatGPT and Perplexity. By integrating AI directly into search, Google aims to retain users who might otherwise turn to these alternatives.

For law firms, this competitive pressure means AI features will likely expand, not contract. Preparing now for an AI-dominated search landscape positions your firm for long-term success.

The Mobile Reality

On mobile devices—where most searches now occur—AI summaries are particularly prominent. They often fill the entire initial screen, pushing traditional results below the fold.

Given that many people search for legal help during stressful moments (often on their phones), mobile-first AI visibility has become essential for client acquisition.

Common Concerns and Misconceptions

As law firms grapple with these changes, several misconceptions have emerged. Let’s address them directly.

“AI Will Just Copy My Content Without Credit”

While AI systems do synthesise information from multiple sources, they typically cite their sources. The research shows AI Overviews average 13.3 source citations per response, while AI Mode responses include even more.

The concern shouldn’t be about AI “stealing” content—it should be about whether your firm is among the cited sources. Being cited drives awareness and credibility, even without direct clicks.

“This Only Affects Big Firms”

Actually, the research suggests AI systems draw from a wide range of sources, not just major brands. Smaller firms with strong topical authority in specific practice areas can compete effectively for AI citations.

The 80% of sources featured in AI responses that don’t rank organically demonstrates that traditional dominance doesn’t guarantee AI visibility—and conversely, that newer or smaller firms have genuine opportunities.

“We Should Wait Until This Stabilises”

AI search features are evolving rapidly, but waiting means falling behind competitors who are adapting now. The firms building AI visibility today are establishing authority that will compound over time.

Moreover, many of the practices that improve AI visibility—creating comprehensive content, building topical authority, maintaining strong reviews—benefit your marketing regardless of how AI specifically evolves.

“Our Practice Area Is Too Niche for AI to Matter”

Even highly specialised practice areas see AI-generated responses. In fact, niche areas may present greater opportunities because fewer firms are competing for AI visibility in those spaces.

If you’re the only firm creating comprehensive content about a specific area of law, AI systems have limited options for sources—making your content more likely to be cited.

Measuring Success in the AI Era

Traditional marketing metrics like organic traffic and keyword rankings remain relevant but incomplete. Consider adding these measurements to your assessment framework.

AI Mention Tracking

How often does your firm appear in AI Overviews and AI Mode responses for your target queries? Track this monthly to identify trends.

Brand Search Volume

As AI drives awareness without clicks, brand searches become a crucial indicator. If people are searching for your firm by name, it suggests AI visibility is working—they encountered your brand somewhere and want to learn more.

Engagement Quality

When visitors do reach your website, how do they behave? SimilarWeb’s research shows that visitors from AI Mode sessions spend more time on-site and view more pages per session than traditional search visitors. Monitor whether this holds true for your firm.

Citation Sources

Which of your content pieces are being cited by AI? Understanding this helps you create more of what works.

Conversion Rates by Source

Track whether AI-driven visitors convert differently than organic search visitors. This data informs how much emphasis to place on AI optimisation relative to traditional SEO.

A comprehensive understanding of marketing measurement helps you interpret these metrics in context.

Looking Ahead: What to Expect

While predictions are inherently uncertain, several trends appear likely based on current trajectories.

Increased AI Trigger Rates

AI Overviews currently appear in roughly 16-30% of searches depending on query type and location. This percentage has grown consistently and will likely continue increasing.

Expanded AI Mode Availability

Currently limited primarily to the US and India, AI Mode will roll out to additional markets including Australia. Law firms should prepare before this expansion reaches their primary markets.

Integration of Ads

Google has begun testing advertisements within AI summaries. As this expands, paid visibility in AI responses may become available—adding another dimension to law firm marketing strategies.

Greater Personalisation

AI responses may become increasingly personalised based on user history and preferences. This could affect which firms appear for which searchers, adding complexity to visibility strategies.

Continued Evolution

Google’s AI features have changed substantially even in the past year. Flexibility and willingness to adapt will serve firms better than rigid adherence to any current best practice.

Taking Action: Your Next Steps

Understanding these changes is the first step. Implementing a response is what actually protects and grows your practice.

Start by auditing your current AI visibility. Search for your key practice areas and note whether your firm appears in AI responses. Identify gaps and prioritise accordingly.

Review your content strategy through an AI lens. Is your content comprehensive enough to serve as a citation source? Does it directly answer the questions potential clients ask? Consider where video content might complement written resources.

Ensure your foundational SEO remains strong. AI visibility builds on SEO fundamentals—technical performance, quality content, and authority signals all contribute.

Consider how your broader digital presence supports AI visibility. Reviews, brand mentions, and engagement across platforms all influence how AI systems perceive your firm.

Finally, commit to ongoing monitoring. The landscape continues evolving, and what works today may need adjustment tomorrow.

Conclusion: Adapting to a Dual AI Reality

Google now runs two distinct AI systems that shape whether potential clients discover your firm. AI Overviews and AI Mode reach similar conclusions using different sources—meaning visibility requires attention to both.

The data is clear: these systems overlap just 13.7% in their citations. Success in one doesn’t guarantee success in the other. Law firms that recognise this reality and adapt their strategies accordingly will maintain visibility while competitors who treat these as a single system fall behind.

The path forward combines strong SEO foundations with emerging GEO practices. Create comprehensive content that establishes topical authority. Diversify across formats to match each system’s preferences. Track your visibility in both AI experiences separately. And remain adaptable as these features continue evolving.

The firms that thrive in this new landscape won’t be those with the biggest budgets—they’ll be those that understand the rules have changed and respond decisively. Your firm can be among them. We can help!
