Your firm’s website is leaking cases. Not because the practice areas are wrong or the copy is weak. It’s because Google can’t crawl half your pages. Your speed scores are in the basement, and your schema is nonexistent. A technical SEO audit finds exactly where the issues are. We’ll cover every technical check that matters for attorney and law firm websites and what failing each one can cost you in rankings.
What a Law Firm Technical SEO Audit Finds
A technical SEO audit is a line-by-line crawl of your site’s infrastructure: the code and server behavior that determine whether Google can find and rank your pages. Think of it as a building inspection: you need to check the wiring and plumbing before worrying about paint.
For law firms, the audit typically covers crawlability and indexation (can Google see your practice area pages at all?), page speed and Core Web Vitals, mobile rendering, site architecture and internal links, schema markup, metadata, HTTPS security, and local signals like NAP consistency across directories.
Google holds legal sites to a higher standard under its “Your Money or Your Life” guidelines, which means a technical mistake that might be invisible on a restaurant site can cost a law firm real ranking positions. An audit flags these compliance issues as well.
Hennessey Digital’s law firm SEO audit covers 50+ checkpoints across technical infrastructure, on-page optimization, backlink health, and user experience. You get a detailed report showing what’s broken and where the growth opportunities are.
Crawlability and Indexation: Can Google Actually Read Your Site?
If Google can’t crawl a page, that page does not exist in search. It doesn’t matter how well-written the content is or how much you paid for it. These three files tell search engines what to crawl:
Robots.txt
Your robots.txt file tells crawlers which pages to access and which ones to skip. A misconfigured line (blocking /practice-areas/ or disallowing your location pages) can pull entire sections of your site out of Google’s index.
XML Sitemaps
XML sitemaps work the other direction: they hand Google a map of every page you want indexed, with priority and update frequency. For multi-practice, multi-office firms, this is important because your site structure is often wider and more complex than a typical small business site.
Canonical Tags
Canonical tags solve the duplicate content problem. If your firm has both www and non-www versions of a page, or HTTP and HTTPS versions, or paginated attorney listing pages, Google sees each one as a separate URL. Without a canonical tag pointing to the preferred version, Google splits your ranking signals across duplicates and sometimes picks the wrong one to index.
Run your site through a crawler like Screaming Frog and look for pages with no canonical, self-referencing canonicals that point to 404s, and canonicals aimed at the wrong URL.
Page Speed and Core Web Vitals Failures
Google’s Core Web Vitals are three metrics that measure real-user experience: Largest Contentful Paint (LCP, target under 2.5 seconds), Interaction to Next Paint (INP, under 200 milliseconds), and Cumulative Layout Shift (CLS, under 0.1). As of September 2026, only 55.9% of websites globally pass all three thresholds.
For law firm websites, the culprits are usually the same:
- Oversized hero images missing width and height attributes
- Chat widgets that load heavy JavaScript on every page
- Cookie banners that fire before the main content renders
- WordPress themes selected for looks over speed
If your firm is already spending on paid media and content but making these mistakes, you may be losing conversion revenue to a slow page. Start with PageSpeed Insights on your top 10 landing pages: your homepage, practice area pages, and attorney profiles. Then, work down from the largest LCP offenders.
Mobile-First Indexing: Why Law Firm Sites Fall Short on Phones
Google now crawls and ranks the mobile version of your site, not the desktop version.
In Q2 2026, 51.48% of global website traffic came from mobile devices (excluding tablets). People looking for a lawyer after a car accident or an arrest are almost always on a phone. However, firms often build desktop pages with case results, attorney bios, detailed practice area descriptions, and FAQ sections but serve a stripped-down mobile version that hides half that content behind accordion menus or removes it entirely.
Check your site with Google’s Mobile-Friendly Test and compare identical content, internal links, and structured data on both versions.
Site Architecture and Internal Linking
Google’s John Mueller has said that internal linking is “super critical for SEO.” Every important page on your site should be reachable within three clicks of the homepage. For firms with multiple practice areas, that means your site architecture needs to be flat enough that Google can crawl from the homepage to a specific practice area page to a location-specific landing page without getting lost in five levels of nested directories.
A URL like yourfirm.com/personal-injury/car-accidents/ is better for both users and crawlers than yourfirm.com/practice-areas/litigation/personal-injury/motor-vehicle/car-accidents/. Practice area keywords in URL paths help you rank.
Issues with internal linking are where multi-office firms usually fall apart. Your Houston personal injury page should link to your Houston car accident page, Houston attorney profiles, and main personal injury hub, and those links should run in both directions. Google also only awards sitelinks to sites with well-organized architecture, so a messy link structure costs you that branded search real estate too.
Schema Markup and Structured Data Checks
Structured data labels your content for Google so it doesn’t have to guess what a page is about. For law firms, the relevant schema types are LegalService, Attorney (Person), Organization, and LocalBusiness.
A 2026 study of 500 personal injury law firm websites in the U.S. found that while 67.6% of sampled firms implemented some form of JSON-LD markup, only 40.0% deploy the LegalService schema type specifically designed for legal service providers.
LegalService schema should be a top priority for any firm. It tells Google your practice areas, service areas, and contact info in a machine-readable format. After that, add Person schema for each attorney with their bar admissions, education, and practice focus, and LocalBusiness schema for every physical office. Larger firms with dozens of attorneys and multiple locations also need to watch for orphaned schema: markup that references pages or people no longer on the site.
Meta Tags, Open Graph, and Metadata Gaps
Potential clients see meta titles and descriptions of your pages in search results. If title tags are missing or duplicate, Google will write its own, and its version will not sell your firm the way you would. Missing meta descriptions drop your click-through rate because searchers see a random snippet instead of a reason to call you.
If your firm invests in social media or public relations, pay extra attention to Open Graph tags. When a news outlet, bar association, or referral partner shares a link to your site, OG tags control the preview card: the image, headline, and description. Without them, LinkedIn and Facebook pull whatever they guess, and the result is usually a broken thumbnail or your site’s footer text.
| Check | Adoption rate (web-wide) | What the gap costs |
| Title tag | 98.5% of mobile pages | Google rewrites your listing; you lose control of the first line prospects see |
| Meta description | 67.2% of mobile pages | Google pulls a random snippet; your CTR drops against competitors who write their own |
| Canonical URL | 67% of mobile pages | Duplicate pages split your ranking signals; Google may index the wrong version |
| Viewport meta | 95.2% of mobile pages | Page fails mobile rendering; ranks drop under mobile-first indexing |
| Robots meta | 47.9% of mobile pages | Pages may be indexed or blocked unintentionally without explicit directives |
| Complete Open Graph tags | 70.6% of all websites | Links shared on social media do not show preview image or description and get fewer clicks |
| og:image | No published figure | Shared links render with a blank gray box instead of your firm’s branding |
| Image alt text coverage | Median page: 60% of images have alt attributes | Lost image search traffic; accessibility failures; weaker on-page relevance signals |
HTTPS and Site Security
HTTPS is a confirmed Google ranking signal. It has been since 2014. But if your law firm website has expired certificates, mixed content warnings (HTTP images or scripts loading on an HTTPS page), or pages loading over HTTP instead of HTTPS, the problems will be significant.
Your website has contact forms where people describe car accidents, criminal charges, divorces, and workplace injuries. An expired SSL certificate puts a full-page browser warning between that person and your intake form. Chrome and Firefox both flag non-HTTPS sites with “Not Secure” in the address bar, and for someone already nervous about reaching out to a lawyer, that warning kills the call.
The audit check here is straightforward: every page on your site should load over HTTPS with a valid, non-expired certificate. And your certificate should be renewed well before it expires.
Local Technical Signals Worth Auditing
For law firms, local SEO is not optional. It is where most of your cases come from. And local SEO has a technical layer that goes beyond just claiming your Google Business Profile.
Your firm’s name, address, and phone number (NAP) need to match across your website, Google Business Profile, and every legal directory where you’re listed. An inconsistent phone number on an old listing can suppress your visibility in the local map pack.
Multi-office firms have it harder. Each location needs a separate landing page with NAP, unique content, local schema, and Google Business Profile. All of that needs to be synchronized.
Treat your Google Business Profile like a second website: fill every field, post updates, respond to reviews, and make sure the categories, hours, and service areas match what’s on your site. Then, implement LocalBusiness and LegalService schema on every location page so Google can connect the dots between your GBP listing and your site content.
How to Run the Audit
Start with a full-site crawl using Screaming Frog or Ahrefs Site Audit. These tools spider your site and flag broken links, redirect chains, missing meta tags, orphan pages, duplicate content, and crawl depth issues. For a typical law firm site with 50 to 500 pages, a Screaming Frog crawl takes less than a minute. For larger firms with a few thousand pages, the process usually finishes in under 10 minutes, assuming default settings are used on a standard computer.
Cross-reference the crawl data with Google Search Console. GSC shows you which pages Google has indexed versus which ones it tried and rejected, and why. It also reports your Core Web Vitals scores, mobile usability errors, and any manual actions or security issues.
Run PageSpeed Insights on your highest-traffic pages and your most important conversion pages (practice area pages and contact/intake pages). Record LCP, INP, and CLS for both mobile and desktop.
Check your structured data with Google’s Rich Results Test and validate your schema markup.
From there, compile everything into a single prioritized spreadsheet: what’s broken and what to fix first.
How Often to Audit and What to Fix First
It depends on how large your site is and how often it changes. A full technical audit every 6–12 months is a reasonable baseline, with lighter monthly monitoring of your Core Web Vitals, index coverage, and crawl errors in Google Search Console.
Run an audit after a site redesign, platform migration, or major content overhaul. These are the events most likely to break things.
For ongoing monitoring, set up alerts in Google Search Console for sudden drops in indexed pages or spikes in crawl errors. Track your CWV scores weekly, especially on mobile. And if you’re running Google Ads or LSAs alongside your organic strategy, poor site speed and broken pages could be dragging down your Quality Score and costing you money on every click.
When you have completed the audit, prioritize the tasks by impact.
- Fix indexation problems first. Pages Google can’t see get zero traffic no matter what else you do.
- Speed and CWV issues come next, because those affect every page on the site.
- After that, look at schema, metadata, and local signals, as these tend to be page-by-page fixes.
- Security issues (expired certs, mixed content) are emergencies and should jump to the top of the list the moment they’re found.
Frequently Asked Questions
How much does a law firm technical SEO audit cost?
The cost depends on the size and complexity of your site. The variables are scope and depth: a crawl-only audit costs less than one that includes CWV optimization, schema implementation, and a prioritized fix roadmap with developer-ready instructions.
How long does a technical SEO audit take?
Analysts can audit smaller firm sites (under 100 pages) in 3–5 business days. Mid-size sites typically take one to two weeks. Larger, multi-location firm websites with thousands of pages and complex architectures may take several weeks, particularly if the audit includes fix instructions written for your developer.
What is the difference between a technical SEO audit and a full audit?
A technical audit looks at infrastructure: crawlability, indexation, speed, mobile rendering, schema, and security. A full SEO audit adds content analysis (are your practice area pages actually ranking for the right terms?), backlink profile review, local SEO evaluation, and competitive benchmarking. You can have perfect technical SEO and still rank poorly if your content is thin or your backlink profile is weak.
Can my web developer handle technical SEO, or do I need an SEO specialist?
A good web developer can fix most technical issues once they’re identified, including redirect chains, speed optimization, schema implementation, and mobile rendering bugs. The audit itself is a different skill set, however. It requires knowing what to look for, what Google’s current standards are, and how to prioritize fixes by their impact on rankings and traffic.
Will fixing technical SEO alone get my law firm ranking on page one?
Not by itself. Technical SEO removes whatever is stopping Google from crawling and ranking your site correctly. Ranking on page one for competitive legal terms also requires good content, a solid backlink profile, local SEO signals, and E-E-A-T compliance.
