E-E-A-T Signal Prevalence Across 100 Law Firm Websites

We analyzed 303 law firm websites across 25 high-growth U.S. markets for 8 key trust signals that Google uses to evaluate expertise and credibility. The average site scores just 4.5 out of 8, and only 20.1% display attorney bar numbers -- the single biggest missed opportunity.

Key Findings
  • Average E-E-A-T score: 4.5 out of 8. Most law firm websites implement roughly half of the trust signals Google looks for, leaving significant room for improvement.
  • Attorney bios lead at 83.8% adoption, followed closely by social proof (79.9%) and publications (79.5%). These three signals are table stakes for competitive firms.
  • Bar numbers are the biggest gap. Only 20.1% of sites display verifiable attorney bar numbers, despite this being one of the simplest and strongest trust signals to add.
  • 15.5% of sites scored zero -- no detectable E-E-A-T signals at all. Meanwhile, only 2.6% achieved a perfect score of 8 out of 8.
  • The most common score was 6 (23.4% of sites), suggesting a clear ceiling where most firms plateau before implementing the harder-to-add signals like bar numbers, trust badges, and professional association listings.

About This Research

E-E-A-T stands for Experience, Expertise, Authoritativeness, and Trustworthiness. It is the framework Google's Search Quality Raters use to evaluate whether a page deserves to rank. For law firms, E-E-A-T is especially critical because legal services fall under Google's "Your Money or Your Life" (YMYL) category, where content quality standards are highest.

Google does not assign a numeric E-E-A-T score. But it does look for concrete signals that demonstrate a firm's credibility: detailed attorney bios, verifiable bar numbers, documented case results, industry awards, client testimonials, published articles, trust badges, and professional association memberships. The more of these signals a site presents, the more reasons Google has to surface it in search results.

We wanted to know how many law firms actually implement these signals. In October 2023, we scanned 303 law firm websites across 25 of America's fastest-growing mid-size markets and scored each site on 8 specific E-E-A-T dimensions. The results reveal a wide gap between what Google expects and what most firms deliver.

Methodology

We collected the top-ranking law firm websites from Google organic search results across 25 high-growth U.S. markets and 2 practice areas (personal injury and family law), yielding 303 unique domains after deduplication.

For each site, we scanned the homepage and key interior pages for the presence or absence of 8 E-E-A-T signals:

  1. Attorney bios -- Named attorney profiles with credentials, education, or experience details.
  2. Social proof -- Client reviews, testimonials, or embedded review widgets (Google, Avvo, etc.).
  3. Publications -- Blog posts, articles, legal guides, or other original content published by the firm.
  4. Case results -- Documented settlements, verdicts, or case outcomes with specific dollar amounts or descriptions.
  5. Awards -- Recognitions such as Super Lawyers, Best Lawyers, Martindale-Hubbell ratings, or local awards.
  6. Trust badges -- Third-party trust indicators like BBB accreditation, SSL seals, or verified membership badges.
  7. Professional associations -- Memberships in bar associations, trial lawyer associations, or specialty legal organizations.
  8. Bar numbers -- Specific state bar license numbers displayed alongside attorney profiles.

Each signal scored 1 point if present, 0 if absent, giving each site a total score from 0 to 8. Detection used a combination of keyword pattern matching, DOM element analysis, and structured data parsing.

Signal Adoption Rates

The 8 signals fall into three clear tiers. Attorney bios, social proof, and publications are near-universal among competitive firms. Case results and awards sit in the middle. Trust badges, professional associations, and bar numbers remain significantly underadopted.

6Trust Badges12139.9%
7Professional Associations9330.7%
8Bar Numbers6120.1%

The drop-off from signal 3 to signal 4 is sharp: publications sit at 79.5%, but case results fall to 61.1%. From there, each subsequent signal loses another 7 to 20 percentage points. The bottom three signals (trust badges, professional associations, bar numbers) are adopted by fewer than 40% of sites.

Score Distribution

The distribution of E-E-A-T scores reveals a bimodal pattern. There is a large cluster at 0 (sites with no signals at all) and a peak at 6 (the "plateau" where firms have covered the basics but stopped short of the hardest signals).

ScoreSites% of Total
04715.5%
110.3%
2103.3%
3206.6%
44314.2%
55116.8%
67123.4%
75217.2%
882.6%

Nearly 1 in 6 sites (15.5%) scored zero. These are typically directory listings, single-page sites, or firms with minimal web presence. At the other end, only 8 sites out of 303 (2.6%) achieved a perfect score of 8 -- implementing every signal we measured.

The most populated score is 6, held by 23.4% of sites. This suggests a natural ceiling: most firms implement attorney bios, social proof, publications, case results, and awards (the top 5 signals), but stop before adding trust badges, professional associations, or bar numbers.

The Bar Number Gap

Bar numbers are the lowest-adoption signal at 20.1%, yet they are arguably the easiest to implement. Every licensed attorney has a bar number. Adding it to a bio page takes minutes. And the signal it sends is powerful: a verifiable bar number confirms the attorney is licensed and in good standing, directly supporting the Expertise and Trustworthiness pillars of E-E-A-T.

The gap is especially notable when compared to the top signal. Attorney bios appear on 83.8% of sites, but only 20.1% of those bios include bar numbers. That means roughly 4 out of 5 firms go to the effort of creating attorney profiles but leave off the single most verifiable credential those profiles could contain.

For firms looking to differentiate, bar numbers represent low-hanging fruit. In a competitive market where 80% of your rivals already have attorney bios and testimonials, adding a bar number is one of the few remaining signals that most competitors have not yet implemented.

What Top Sites Do Differently

We compared sites scoring 7 or 8 (60 sites, 19.8% of the sample) against sites scoring 0 to 2 (58 sites, 19.1%). The differences illustrate what separates firms that invest in trust signals from those that do not.

Top-tier sites (score 7-8) share a clear profile:

  • 100% have attorney bios, social proof, and publications. These three signals are universal among top performers.
  • Bar numbers appear on 40%+ of top-tier sites -- double the overall average of 20.1%. This is the signal that most differentiates top-tier from mid-tier.
  • Professional associations are present on 60%+ of top sites, compared to just 30.7% overall. Membership badges from organizations like the American Association for Justice or state trial lawyer associations are common.
  • Trust badges (BBB, SSL, verified reviews) appear on 70%+ of top sites, nearly double the 39.9% overall adoption rate.

Bottom-tier sites (score 0-2) are defined by absence. Most have no attorney bios, no testimonials, no blog, and no case results. Many are directory-style listings or placeholder sites. The gap between a score of 2 and a score of 6 often comes down to four additions: attorney bios, client testimonials, a blog, and documented case results.

Limitations

  • Automated detection: Signal detection used keyword matching and DOM analysis. Some signals may be present in formats our scanner did not recognize (e.g., bar numbers embedded in images rather than text).
  • Binary scoring: Each signal is scored as present or absent. We did not measure quality or depth -- a firm with 1 blog post and a firm with 500 receive the same "publications" credit.
  • Homepage bias: While we scanned interior pages where possible, some signals may exist on pages our crawler did not reach.
  • Point-in-time snapshot: Data was collected in October 2023. Websites change frequently, and adoption rates may have shifted since collection.
  • Geographic focus: Our 25 markets are fast-growing mid-size cities. Results may differ in major metros or rural areas where competitive dynamics are different.

Frequently Asked Questions

What is E-E-A-T and why does Google care about it?
E-E-A-T stands for Experience, Expertise, Authoritativeness, and Trustworthiness. It is the framework Google's Search Quality Raters use to evaluate page quality. For law firms, E-E-A-T is critical because legal services fall under Google's "Your Money or Your Life" (YMYL) category, where quality standards are highest. Pages with strong E-E-A-T signals -- such as attorney credentials, case results, and professional memberships -- are more likely to rank well in search results for competitive legal queries.
How did you measure E-E-A-T signals on law firm websites?
We scanned each site's homepage and key interior pages for 8 specific signals: attorney bios, bar numbers, case results, awards and recognitions, trust badges (such as BBB or SSL seals), social proof (client reviews or testimonials), publications (blogs or articles), and professional association memberships. Each signal was scored as present (1) or absent (0), giving each site a total score from 0 to 8. Detection used keyword pattern matching, DOM element analysis, and structured data parsing.
Why are bar numbers such a low-adoption signal?
Only 20.1% of the 303 sites in our study display attorney bar numbers. This is likely because many firms do not realize bar numbers serve as a strong trust signal for both Google and potential clients. Displaying a verifiable bar number confirms the attorney is licensed and in good standing, which directly supports the Expertise and Trustworthiness dimensions of E-E-A-T. It is one of the simplest signals to add, yet it remains the least adopted of the 8 signals we measured.
What is a good E-E-A-T score for a law firm website?
In our study, the average score was 4.5 out of 8. Sites scoring 7 or 8 represented the top tier, accounting for 19.8% of all sites analyzed. A score of 6 or above places a firm well above the median. The most common score was 6, achieved by 23.4% of sites. Firms scoring 0 to 2 are significantly underinvesting in trust signals that Google and potential clients look for.
Which E-E-A-T signals matter most for law firm SEO?
All 8 signals contribute to a comprehensive E-E-A-T profile, but attorney bios (83.8% adoption), social proof (79.9%), and publications (79.5%) are the most widely adopted because they are the most visible to users. The signals with the largest competitive gap are bar numbers (20.1%), professional associations (30.7%), and trust badges (39.9%). Adding these underutilized signals can meaningfully differentiate a firm from competitors who have already covered the basics.
