AI Content Is Everywhere in Law Firm Search Results. But is it working?

Every law firm marketing conference, webinar, or workshop I have attended in the past year has featured at least one panel debating whether AI-generated content will help or hurt your Google rankings. The conversation usually splits into two camps. One side argues that Google will eventually crack down on AI content and punish anyone using it. The other side argues that AI content is the future and firms that do not adopt it will fall behind.

Both sides are wrong. And we now have the data to prove it.

Custom Legal Marketing recently completed a study of 2,435 law firm rankings in Google across 8 practice areas, 28 keywords, and 24 U.S. cities using our CLM Sequoia AI marketing platform. You can read the full report on law firms using AI content for marketing on our website. But what I want to talk about here is not the data itself. It is what the data means for how law firms should be making decisions about content right now.

The Debate Is Over. AI Content Is Neutral.

The correlation between AI content percentage and ranking position in our study didn't even come back as a weak signal. The correlation was essentially no signal. There is no statistically significant relationship between how much AI content a page contains and where it ranks in Google's organic results.

This should end the debate in both directions. Google is not penalizing AI content. Pages with 99% and even 100% AI-detected content are sitting in Position 1 for keywords like "car accident lawyer" in New York, "truck accident lawyer" in Chicago, and "motorcycle accident lawyer" in Seattle. At the same time, Google is not rewarding it. Pages with almost no AI content rank just as well, and in some brackets, slightly better.

For law firm marketing directors and managing partners, this means you can stop worrying about whether your competitors are using AI and start worrying about the things that actually matter.

The Real Story Is the Readability Problem

Here is what caught my attention more than any other finding in this study. There is a strong, statistically significant negative correlation (r = -0.233, p < 0.0001) between AI content percentage and readability. The more AI content a page has, the harder it is to read.

This should concern every firm that has been leaning on AI tools to produce practice area pages and blog content without serious editorial oversight. AI tools are remarkably good at producing text that is grammatically correct, factually reasonable, and comprehensive in scope. They are also remarkably consistent at producing text that is structurally dense, loaded with qualifiers, and written at a reading level that assumes the reader has a law degree.

Your prospective clients do not have law degrees. They have broken bones, totaled cars, wrongful termination notices, and custody disputes. They are reading your website on their phone in a hospital waiting room or at 2 a.m. when they cannot sleep because they are worried about how they are going to pay their medical bills. If your content reads like it was written by a machine that consumed every legal brief ever filed, you are losing those people.

The irony is that many firms adopted AI tools specifically to produce more content faster. But producing more content that nobody can comfortably read is not a content strategy. It is a waste of a ranking.

Authority Still Wins. It Has Always Won.

When we looked at which firms are ranking at Position 1 with heavy AI content, the list read like a who's who of nationally recognized personal injury brands. Morgan & Morgan. Michigan Auto Law. GJEL. Kline & Specter. These firms are not ranking because of their content. They are ranking because of decades of earned authority, massive backlink profiles, national brand recognition, and the kind of trust signals that no amount of AI-generated text can replicate.

This is the part of the data that smaller and mid-sized firms need to pay close attention to. The firms succeeding with AI content have already built the foundation that makes content quality a secondary concern. Their domain authority carries the weight. A 50-attorney firm in Charlotte or a solo practitioner in Indianapolis does not have that luxury. For those firms, content quality, readability, and depth are not nice-to-haves. They are the primary competitive lever.

The study showed that word count has a statistically significant correlation with rankings (p = 0.042), which is more than AI content percentage can claim. Firms that invest in substantive, well-written content in the 500 to 2,000 word range are measurably better positioned than firms producing thin pages, whether those thin pages were written by a human or a machine.

The Blended Approach Is Winning

One of the more interesting findings buried in the data is that pages with 26 to 50% AI content achieved the best average ranking position (2.83) and the highest average word count (2,958 words) of any bracket we measured. These are almost certainly pages where AI was used as a starting point or a supplement, and then a human writer substantially expanded, restructured, and edited the content.

This makes intuitive sense. AI is excellent at producing a first draft, generating an outline, summarizing research, or filling in sections of a longer piece. Humans are excellent at making that content readable, adding genuine expertise, and structuring it in a way that actually helps someone who is trying to figure out whether they have a case.

The firms that figure out this workflow, using AI for efficiency while maintaining human editorial control for quality, are going to have a meaningful advantage over firms that go all-in on either extreme. Pure AI content tends to be thin (averaging just 1,561 words in the 71-100% bracket) and hard to read. Pure human content is excellent but expensive and slow to produce at scale. The middle path produces the most content, the best content, and the best rankings.

What This Means for Your 2026 Content Strategy

If you are a law firm marketing director reading this, the takeaway is not complicated. AI content is not going to get you penalized and it is not going to be your secret weapon. It is a production tool, and like every production tool, its value depends on what you do with the output.

Stop spending energy on the AI content debate. Redirect that energy toward building real authority through earned media, strategic link building, and consistent content production. If your firm is using AI to produce content, invest in editorial resources to make that content readable. If your firm is not using AI at all, you are probably leaving efficiency on the table, but you are not at a competitive disadvantage in rankings.

The firms that will win in competitive legal search over the next few years are not the ones that produce the most content or the most AI content. They are the ones that produce the most useful content, backed by the strongest authority signals, written at a reading level that respects the people they are trying to help.

That has always been true. AI has not changed it.
