AI Overviews are reshaping how clients choose law firms

AI Overviews are no longer a novelty in legal search. They are acting like a gatekeeper, narrowing the field before a client ever reaches a law-firm homepage, and that is a serious shift when general counsel, family office principals, and corporate boards are already using AI search engines to pre-screen outside counsel.

The first impression now happens in the answer box

The hard truth in this report is simple: if an AI Overview appears, the client’s short list may already be taking shape. The release says 78% of legal queries now trigger a Google AI Overview, the highest rate of any industry in the Semrush analysis it cites, and that means legal discoverability is being compressed into a single, highly influential visibility layer.

That matters because the old path to a law firm, referrals, directory pages, and a careful wander through practice-area pages, is getting cut shorter. The report says AI-referred prospects convert at 4.4 times the rate of standard organic visitors, which is exactly why firms should care about more than traffic volume. The real question is whether the right prospects see enough of the right signals to trust the firm before they click.

Why prestige is not automatically winning

This is where the report’s “white-shoe visibility paradox” lands hardest. Many of the most prestigious firms built their reputations inside closed networks, where the name travels through relationships, boardrooms, and institutional memory. That can work beautifully in a referral economy, but it is a weakness in an AI economy, because answer engines need a broad, legible public footprint to work with.

The report argues that historical reputation is not enough if a firm has underinvested in public-web visibility. In practice, that means the firms most likely to be considered by sophisticated clients are no longer just the ones with the strongest pedigree. They are the ones whose expertise is easy for machines to parse, verify, and summarize.

The click-through math is getting ugly

The numbers behind the shift are brutal. The report says that when an AI Overview appears, only 8% of users click a traditional result, compared with 15% without an overview. That is not a small dip. It is a structural change in how attention gets distributed, and it helps explain why firms that rely on organic search alone may be watching the top of funnel shrink without fully realizing why.

Semrush’s updated study gives that trend more shape. Using more than 10 million keywords and Datos clickstream data, it found that AI Overviews appeared for 6.49% of keywords in January 2025, peaked near 25% in July 2025, and settled at 15.69% in November 2025. Just as important, the mix of queries changed: in January, 91.3% of overview-triggering searches were informational, but by October that share had fallen to 57.1% as commercial and transactional queries rose.

That shift should get every legal marketing team’s attention. If AI Overviews are moving deeper into commercial territory, they are no longer just answering “what is a merger agreement” or “how does arbitration work.” They are getting closer to the questions that precede hiring decisions.

What authority looks like to an answer engine

The takeaway for firms is not to chase gimmicks. It is to strengthen the signals that AI systems can reliably interpret as authority, trust, and specialization. The report points toward public-web visibility, authoritative citations, and a web footprint that machines can easily parse, which is a very different discipline from building a glossy brochure site and hoping reputation does the rest.

In practical terms, that means firms need to make their expertise easier to verify. A strong AI-visible presence tends to come from content that is specific, structured, and clearly tied to practice depth rather than vague positioning. If a firm wants to show up in AI-generated answers, it needs to look less like a brand statement and more like a credible source.

A useful checklist looks like this:

• Publish substantive practice-area content that reflects real matters, not generic slogans.
• Make pages easy for systems to parse, with clear service labels, topic depth, and clean structure.
• Build a public trail of authority through citations, commentary, and original analysis.
• Strengthen specialization signals so the firm is legible for narrow, high-value legal queries.
• Treat visibility as a trust problem, not just a search problem.

That last point is the one too many firms miss. AI search is rewarding content that helps answer a question cleanly and credibly. A firm that can demonstrate why it belongs in the answer, not just why it exists, has a much better shot at staying in the frame.

Internal adoption is lagging behind external pressure

The awkward irony is that many firms are still catching up internally even as AI search reshapes how they are found externally. The American Bar Association and MyCase surveyed more than 2,800 legal professionals for their 2025 report, and 31% said they personally used generative AI at work in 2024, up from 27% in 2023. But firm-wide use was only 21% in 2024, down from 24% in 2023, which shows how uneven adoption still is inside the industry.

That gap matters because firms cannot manage AI visibility well if they are only experimenting at the margins. Marketing, business development, and practice leaders need to think together about what the firm publishes, how it is structured, and whether its expertise is discoverable by systems that now sit between the client and the website.

Google is still changing the rules

The search environment itself is not settling down either. Google says AI Overviews launched in the United States in May 2024, expanded on May 20, 2025 to more than 200 countries and territories and more than 40 languages, and drove more than a 10% increase in usage of Google in the United States and India for the types of queries that show AI Overviews. Google has also called AI Overviews one of the most successful launches in Search in the past decade.

Now Google is pushing further with AI Mode, a deeper, query fan-out-based experience that goes beyond standard search. In May 2026, it said it was adding more direct links, article suggestions, and previews of websites inside AI Mode and AI Overviews to surface original content and trusted sources more easily. That is a telling move: even as AI answers compress choice, Google is trying to keep the best source material visible inside the answer layer itself.

For law firms, the direction of travel is clear. The firms that remain visible will not just be the most famous names in the room. They will be the firms with the clearest proof of expertise, the strongest public signals of trust, and the most machine-readable specialization. In a market where AI Overviews can narrow the field before the first click, that is no longer a marketing edge. It is table stakes.
