Summary

• Google released three core algorithm updates in 2025 (Google’s 2025 Algorithm Updates) alongside revised Search Quality Rater Guidelines that specifically instruct human evaluators to assign the lowest quality rating to pages dominated by AI-generated content lacking original value.
• Law firms that scaled content production using AI tools without meaningful human oversight saw significant drops in organic visibility, with some legal websites losing the majority of their search traffic.
• Legal content is classified as Your Money Your Life (YMYL) under Google’s framework, meaning it faces stricter quality scrutiny than most other sectors, and E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) signals carry decisive weight.
• AI Overviews now appear in a growing share of legal search queries, reducing organic click-through rates by up to 61% and creating a dual challenge for firms already hit by content quality penalties.​
• The UK Competition and Markets Authority has proposed conduct requirements for Google, including allowing publishers to opt out of AI Overviews, signalling a regulatory shift that will reshape how legal content is surfaced in search.

The relationship between Google and AI-generated content reached a turning point in 2025 thanks to Google’s 2025 Algorithm Updates. Over the past 12 months, Google deployed three core algorithm updates, revised its Search Quality Rater Guidelines, and expanded its AI Overviews feature across legal search queries. The combined effect was a reckoning for websites that had relied on machine-produced text to fill their pages. For the UK legal sector, a profession that depends on trust, accuracy, and demonstrable expertise, the consequences have been sharp and instructive.

Google’s 2025 Core Algorithm Updates: The Year in Review

Google’s 2025 Algorithm Update followed a deliberate rhythm. The March 2025 Core Update, which began rolling out on 13 March and was completed by 27 March, focused on improving the ranking of high-quality content while reducing the visibility of low-value, unhelpful, or outdated pages. Industry analysts observed increased scrutiny on AI-generated content that lacked depth, stricter evaluation of content authority and expertise, and greater emphasis on originality and user experience.​

The June 2025 Core Update arrived on 30 June and completed on 17 July. It continued the direction set in March, with Google’s E-E-A-T framework carrying even greater weight for professional services including law firm SEO.​

The December 2025 Core Update, which ran from 11 to 29 December, introduced what analysts described as targeting of “experience dilution”: content that technically covers a topic but lacks genuine first-hand expertise or original insight. One SEO consultant reported that a site they worked with lost 60% of its traffic, despite publishing content that was “well-written, grammatically perfect” and covered all the basics. The problem was that the content was “completely indistinguishable from 50 other sites covering the same topics in the same way.”

Between these core updates, Google also released an August 2025 Spam Update with improved detection of auto-generated content, keyword stuffing, and manipulative ranking practices.

The January 2025 Search Quality Rater Guidelines: A Quiet Revolution

The most telling signal of Google’s intent came earlier in the year. In January 2025, Google published a significant update to its Search Quality Rater Guidelines, the internal playbook used by approximately 16,000 human evaluators worldwide to assess whether web pages deserve their rankings.

The update introduced a formal definition of generative AI content and provided specific guidance on how raters should assess it. Google described generative AI as “a helpful tool for content creation” while noting it “can also be misused.” The critical passage appeared in sections covering low-quality and spam content. Under the heading of scaled content abuse, Google stated that using “automated tools (generative AI or otherwise) as a low-effort way to produce many pages that add little-to-no value for website visitors” should attract the lowest quality rating.

Section 4.6.6 went further: “The Lowest rating applies if all or almost all of the MC [main content] on the page (including text, images, audio, videos, etc) is copied, paraphrased, embedded, auto or AI generated or reposted from other sources with little to no effort, little to no originality, and little to no added value”.

John Mueller, Google’s Senior Search Analyst and Search Relations team lead, confirmed the direction at Search Central Live in Madrid. Quality raters are now asked to assess whether the main content of a page is auto or AI-generated, and if so, to rate it low. The guidelines also introduced a new section on filler content, noting that “filler can artificially inflate content, creating a page that appears rich but lacks content website visitors find valuable”.​

These ratings do not directly alter search rankings. They feed into a system of structured feedback that shapes how future algorithm updates are designed. The guidelines function as a preview of what the algorithm will soon reward or penalise at scale.

Why Law Firms and YMYL Legal Content Felt It First

Legal content occupies a uniquely exposed position in Google’s quality framework. It falls squarely within the Your Money Your Life (YMYL) category, a classification Google applies to content that can directly affect a person’s health, financial stability, safety, or wellbeing. YMYL content faces stricter quality expectations than other categories, and the penalties for falling short are correspondingly steeper.

Google’s E-E-A-T framework (Experience, Expertise, Authoritativeness, Trustworthiness) carries particular weight for legal pages. A guide on settlement agreements written by a qualified solicitor who includes anonymised case examples, lists their professional credentials, and references relevant legislation will perform differently from an AI-generated summary that offers the same information without any evidence of lived professional experience.

The problem for law firms is that many embraced AI content tools with enthusiasm during 2023 and 2024. The appeal was obvious: producing blog posts, practice area descriptions, and FAQ pages at speed and scale, often without involving fee earners in the writing process. Some firms outsourced content to agencies that used AI tools to produce material at volume. The result, in many cases, was websites populated with competent but interchangeable text that failed to meet the E-E-A-T standards Google now enforces rigorously.​

As one industry observer noted, pages were “written in a hurry, lifted from older material, or created by AI with little or no human oversight. Writers without legal experience often miss nuance.” The output was predictable: pages that did not appear in search results, AI tools that misinterpreted the messaging, readers who lost interest within seconds, and calls to action that felt hesitant or unclear.

Google’s 2025 Algorithm Updates Impact on Organic Search Traffic

The traffic data paints a clear picture. Research from Search Engine Land found that organic click-through rates on queries featuring AI Overviews fell by 61%, paid click-through rates dropped by 68%, and even on queries without AI Overviews, organic CTRs declined by 41% year-on-year. Law firms experienced a median 42% drop in search impressions following September 2025, when AI Overviews expanded aggressively into commercial legal queries.​

An Ahrefs study found that when Google’s AI Overview appears, the top-ranking webpage loses roughly 34.5% of its usual click-through rate. During Google’s Search Generative Experience testing, some websites saw traffic drops ranging from 18% to 64% in organic visits.

For law firms, the effects of Google’s 2025 Algorithm Updates are significant. Many potential clients begin their journey with informational searches: “Can I be dismissed while on sick leave?” or “What counts as constructive dismissal?” These are precisely the queries where AI Overviews now dominate. Google synthesises information from various sources and presents an answer that often satisfies the searcher’s immediate need. A firm’s expertise might be included in that answer, but the firm receives no credit, no visit, and no opportunity to convert that person into a client.​

Roughly 9,000 UK-based sites experienced significant traffic disruption following the December 2025 update alone. The December 2025 Helpful Content Update specifically targeted what Google termed “experience dilution,” and the algorithm now evaluates demonstrable expertise markers, original data or perspectives, and depth of implementation detail.

AI Overviews and Law Firm SEO: The Double Blow

The algorithm updates arrived alongside the aggressive expansion of Google’s AI Overviews, creating a compounding problem for law firm SEO strategies. AI Overviews are automatically generated summaries displayed at the top of search results, drawing on multiple online sources to answer user questions directly. Their rollout has affected search queries related to family law, conveyancing, wills, employment law, and business formation.

The traditional search model was straightforward. Create quality content, optimise for search engines, build authority, and rank on page one. AI Overviews disrupted this model fundamentally. Google pulls information from multiple sources and generates a summary answer directly on the search results page. The user gets their answer without clicking anywhere. By February 2026, AI Overviews appear in six of every ten Google searches, with legal queries triggering overviews at an even higher rate.

There is a silver lining in the data. Firms mentioned within AI-generated responses experience 35% more organic clicks and 91% more paid clicks compared to those omitted. Being referenced by Google as a trusted source can directly improve engagement, even as total website visits decline. The firms that fare best are those whose content is authoritative enough to be selected as a source for AI-generated answers, a form of generative engine optimisation (GEO) that is fast becoming essential for legal marketing.

The Law Society of Ireland tested Google’s AI Overview feature and discovered alarming inaccuracies. When asked to name the last five solicitors struck off the roll, it returned a list in which four of the five individuals had never been struck off. The AI tool erroneously cited the Law Society’s website as its source. This incident illustrates both the power and the risk of AI Overviews in the legal context, where misinformation carries professional and personal consequences.

The SRA and the AI Content Question

The Solicitors Regulation Authority has been active on AI matters from a different angle. In May 2025, the SRA authorised Garfield.Law Ltd as the first fully AI-driven law firm to provide regulated legal services in England and Wales. SRA chief executive Paul Philip noted that “responsible use of AI by law firms could improve legal services, while making them easier to access and more affordable.”

The SRA’s approach has focused on consumer protection, quality assurance, and safeguarding against AI hallucinations. Its interest in AI accuracy within regulated legal services echoes Google’s concerns about AI-generated content quality. Both the regulator and the search engine are, in different ways, grappling with the same question: how do you maintain standards of accuracy and trustworthiness when machines produce the content?​

For firms producing solicitor website content, the SRA’s commitment to professional standards provides an additional reason to ensure that published material reflects genuine legal expertise. Content that attracts a Google penalty for being thin, generic, or misleading also risks falling short of the professional standards clients expect of a regulated solicitor.

What Law Firms Should Do Now: An SEO and Content Strategy Guide

The firms that will maintain visibility following Google’s 2025 Algorithm Updates are those that treat content as a professional output rather than a marketing commodity. Several practical steps follow from Google’s 2025 direction.

Invest in Expert-Led Legal Content

Every article, guide, or FAQ should be written or substantively reviewed by a qualified solicitor or legally qualified copywriter. Author credentials should be visible, with clear bios explaining the writer’s experience and specialism. AI tools can assist with research, planning, and initial drafts, but the final published content must carry genuine professional insight. This is the foundation of E-E-A-T compliance for YMYL legal content.

Structure Content for AI Retrieval and Generative Engine Optimisation

AI search systems break web pages into digestible chunks and assess each section for authority and relevance. Self-contained paragraphs, descriptive headings, and clear Q&A blocks increase the likelihood that a firm’s content will be selected for AI Overviews and generative search results. Structured data markup, including schema for legal services, FAQs, and reviews, helps both Google and AI platforms parse content correctly. Pages with structured data are 36% more likely to appear in AI summaries.

Prioritise Specificity Over Volume

The December 2025 update rewarded content that “could only be created by someone with real expertise and experience”. Generic how-to guides that cover the same ground as hundreds of other articles were filtered out. Shorter pieces written by practitioners with evident daily experience outranked longer compiled guides that lacked specificity.​

Strengthen Local SEO for Solicitors

Small and medium-sized law firms often outperform larger competitors in local search when SEO is consistent. Targeting long-tail keywords that reflect specific services and locations, such as “child arrangements solicitor Milton Keynes” or “employment contract advice Bristol,” helps firms appear where clients are ready to instruct. Google Business Profiles should be fully updated with photos, office hours, and verified contact details.

Monitor New Visibility Metrics Including AI Search

Traditional measures of success, such as traffic volume and click-through rates, tell an incomplete story in the AI Overviews era. Firms should track share of voice in AI-generated results, branded query performance, and impression share alongside conventional analytics. Citation frequency in AI-generated summaries is becoming a key performance indicator.

Audit Existing Website Content

Many law firm websites contain years of articles that no longer meet current quality standards. A planned editorial review should identify pages that are thin, outdated, or indistinguishable from competitors. These pages should be substantively updated with genuine expertise rather than deleted, as removing them can cost the historical authority they have built.​

The Opportunity for Mid-Tier and Boutique Law Firms

There is genuine opportunity in the upheaval created by Google’s 2025 Algorithm Updates. Analysis of AI search results shows that the firms consistently recommended by Google’s AI Mode and ChatGPT are not always the biggest names. They are the ones with the clearest, most helpful, best-structured content. Size matters less than quality and clarity.​

For mid-tier and boutique firms, this represents a levelling effect. A three-partner practice that publishes authoritative, well-structured guidance on its core practice areas can outperform a large firm with a website full of generic, AI-generated material. The marketing budget of a Magic Circle firm is not required. What is required is content that demonstrates genuine legal knowledge, structured for both human readers and machine retrieval.​

Looking Ahead: Law Firm SEO in 2026 and Beyond

Google’s directional shift is clear: it is moving away from rewarding content that simply answers queries correctly, towards content that demonstrates actual expertise and experience. The bar for “helpful” has risen. AI tools that produce technically accurate but interchangeable content will continue to underperform against material written with professional authority.

The emergence of answer engine optimisation (AEO) and generative engine optimisation (GEO) as distinct disciplines signals that law firms must now optimise for multiple AI platforms simultaneously, not just Google, but ChatGPT, Perplexity, and other large language models that increasingly influence how clients find legal services.

The firms that adapt their content strategy now, combining legal expertise with modern content structuring, building authority through published thought leadership, and engaging with the new metrics that matter, will maintain client visibility. Those that continue to rely on volume-driven AI content will watch their search presence diminish.

Google is not anti-AI. It is anti-mediocrity. For the legal profession, that distinction should feel familiar.

FAQs

Has Google banned AI-generated content from search results?

Google’s 2025 Algorithm Updates did not ban AI-generated content. Its position is that AI copy is acceptable when it is “helpful, original, and written for people”. The January 2025 Search Quality Rater Guidelines instruct evaluators to assign the lowest quality rating to pages where AI-generated content dominates without added value, insight, or originality. The target is low-effort, mass-produced content rather than AI-assisted writing that includes genuine human expertise.

Why are law firm websites particularly vulnerable to Google’s algorithm updates?

Legal content falls within Google’s Your Money Your Life (YMYL) category, which applies to material that can directly affect a person’s health, finances, safety, or wellbeing. YMYL content faces stricter quality expectations and heavier scrutiny through the E-E-A-T framework (Experience, Expertise, Authoritativeness, Trustworthiness). AI-generated legal content that lacks demonstrable professional expertise is therefore more likely to be downgraded than equivalent content in less sensitive sectors.

How many Google core updates were there in 2025?

Google released three core algorithm updates in 2025: the March 2025 Core Update (13 to 27 March), the June 2025 Core Update (30 June to 17 July), and the December 2025 Core Update (11 to 29 December). An August 2025 Spam Update also targeted manipulative practices including auto-generated content.

What is the CMA doing about Google AI Overviews and UK publishers?

In January 2026, the UK Competition and Markets Authority proposed conduct requirements for Google under the Digital Markets, Competition and Consumers Act 2024, including allowing publishers to opt out of their content being used in AI Overviews without being penalised in traditional search results. Google would also be required to properly attribute publisher content in AI-generated responses. The proposals followed Google’s designation with Strategic Market Status in October 2025.

Can a law firm still use AI tools for content creation?

Yes, provided AI is used as part of a human-led process. Google’s guidelines emphasise that intent, effort, and originality matter more than the tools used to produce content. The recommended approach is to use AI for research, planning, and initial drafts, then ensure qualified professionals review, edit, and enhance the material with genuine insight, practical examples, and professional authority. Content that is indistinguishable from what any AI tool could produce without specialist input is at risk of being downgraded.

What is generative engine optimisation (GEO) and why does it matter for law firms?

Generative engine optimisation is the practice of structuring content so that AI systems, including Google AI Overviews, ChatGPT, and Perplexity, select it as a source when generating answers. For law firms, GEO matters because a growing share of potential clients now receive AI-synthesised answers rather than clicking through to websites. Firms whose content is cited in these AI-generated responses experience significantly higher engagement.
