A mobile friendly law firm website is built for the person who finds you at 11pm, on a phone, after the worst day of their year. When we wrote the brief for the Law Office of Aaron P. McAllister site, that person shaped every page: criminal defense is chosen under stress, usually at night, usually on a phone, often by a family member rather than the client. Desktop polish does nothing for them. A phone number they can tap does.
This is what we check on attorney sites before we touch the design, and the fixes that tend to matter most.
Key Takeaways
- Google indexes and ranks the mobile version of your pages, so anything missing on mobile is missing from search.
- The first screen on a phone should show who you help, a tap-to-call number and one way to start a case review.
- Core Web Vitals have published targets: loading within 2.5 seconds, responses within 200 milliseconds, layout shift of 0.1 or less.
- Short intake forms and thumb-sized buttons win more first contacts than any visual flourish.
- Test the site the way clients use it: on a phone, on cellular data, after hours.
Why the phone version is the real website
Google settled this for search. Its documentation says it uses the mobile version of a site's content, crawled with a smartphone agent, for indexing and ranking. A practice area page that collapses half its text behind tabs on mobile, or a location page that only exists in the desktop menu, is weaker in search than it looks on your office monitor.

The same page also recommends responsive design: one set of HTML on one URL, with the layout adjusting to the screen. That is what we build on. Separate mobile sites made sense years ago. Today they mostly create two versions of the content that slowly drift apart.
What the first screen has to answer
On a phone you get one screen before the visitor decides whether to scroll or leave. For a law firm that screen has three jobs. Tell them what kind of matters you take, in their words. Give them a number they can tap. Offer one clear next step, usually a free case review.
Many attorney sites we review spend that screen on a slideshow, a skyline photo or a quote about justice. All of it pushes the phone number below the fold. For a family member searching on behalf of someone who was just arrested, that is one scroll too many.
The mobile audit we run on attorney sites
Before any redesign we work through the same checklist. It takes an hour, and it usually finds more than a design review would.
| Check | What good looks like | Common failure |
|---|---|---|
| Tap-to-call | Number in the header as a tel: link on every page | Number shown as an image or plain text |
| Navigation | Practice areas reachable in one or two taps | Mega menu that needs hover to open |
| Intake form | Four or five fields, works with autofill | Twelve fields and a CAPTCHA |
| Tap targets | Buttons and links at least 24 by 24 CSS pixels with space around them | Footer links crammed together |
| Loading | Largest Contentful Paint within 2.5 seconds | Autoplay hero video, uncompressed photos |
| Stability | Cumulative Layout Shift of 0.1 or less | Chat widget that pushes the page down as it loads |
| Content parity | Same practice area text on phone and desktop | Sections hidden on mobile to save space |
The tap target size comes from WCAG 2.2, which sets 24 by 24 CSS pixels as the minimum target size at level AA, with exceptions for inline links and well-spaced targets (W3C, Understanding Target Size (Minimum)). Bigger is kinder. People with tremors, people holding a coffee and people in a parked car all miss small buttons.
Speed: the part clients feel and never mention
Nobody emails a firm to say the website was slow. They just leave. Google's Core Web Vitals give you a way to measure what they feel. Largest Contentful Paint should land within 2.5 seconds, Interaction to Next Paint should be 200 milliseconds or less, and Cumulative Layout Shift should stay at 0.1 or below, measured at the 75th percentile of page loads (web.dev, Web Vitals).
On law firm sites the same culprits appear again and again. A full-width hero video. Attorney headshots uploaded straight from the photographer at several megabytes each. Three chat and call-tracking scripts that all load before the content. A review widget that shifts the page halfway through reading. Each one is easy to fix once you know it is there.
Navigation for a multi-practice firm
A firm with eight practice areas cannot put eight items in a phone menu and expect anyone to read them. We group them the way clients think: by what happened to them, not by the firm's internal departments. "Arrested or charged", "Hurt in an accident", "Divorce and custody" reads faster than a list of legal terms.
Each group then gets its own page with a short answer at the top, the charges or matters it covers, and the same call button. On the McAllister build that meant seven practice area pages, each written to its own charges, and a free case review intake that does not depend on office hours.
Forms and calls that survive a phone
Intake is where mobile design earns its money. Every field you add to a contact form is one more thing to type with a thumb. Ask for name, phone, a short description and the type of matter. Collect the rest on the call.
Two smaller details matter more than they look. Use the right input types so the phone shows a number pad for the phone field. And show a clear confirmation after submit, with the number to call if it is urgent. A visitor who is unsure whether the form went through will often submit again, call, or give up.
Family law adds one more: many visitors are using a shared phone or a shared computer. A quick-exit button and no saved autofill on sensitive forms are worth discussing with the firm.
Local search starts on the phone
Searches like "DUI lawyer near me" happen on phones, and the results lean on the map and the firm's Google Business Profile as much as the website. A mobile friendly site helps here in a plain way: the address, hours and phone on the site should match the profile exactly, and each office should have a page a phone user can open from the map listing. Our SEO services start with that consistency before any content work.
How often to recheck
Mobile problems creep back in. Someone adds a new chat tool, a new hero photo or a pop-up for a webinar, and the site gets slower without anyone noticing. We look at the Core Web Vitals report in Search Console monthly and run the phone checklist after any change to the header, forms or homepage.

Frequently Asked Questions
What makes a law firm website mobile friendly?
The page fits a phone screen without zooming, the phone number is a tap-to-call link, the practice areas are reachable in one or two taps, buttons are big enough to hit with a thumb, and the page loads quickly on a mobile connection. Google recommends responsive design, which serves the same page to every device and adjusts the layout to the screen.
Does Google rank law firm websites on the mobile version?
Yes. Google Search Central says Google uses the mobile version of a site's content, crawled with the smartphone agent, for indexing and ranking. If your mobile pages hide content or practice area text that the desktop version shows, Google may not see it.
What are Core Web Vitals and why do they matter for attorneys?
They are three Google measures of page experience: Largest Contentful Paint for loading (good is 2.5 seconds or less), Interaction to Next Paint for responsiveness (200 milliseconds or less) and Cumulative Layout Shift for visual stability (0.1 or less). Slow, jumpy pages lose people who are already stressed before they ever reach the intake form.
How short should a mobile intake form be?
As short as your intake team can live with. Name, phone, a short description and a matter type dropdown is enough for a first contact at most firms. Anything you need for a conflict check can be collected on the call. Every extra field on a phone is another chance for the visitor to give up.
How do I test my law firm site on mobile?
Open it on your own phone at night, on cellular data, and try to call the firm and submit the contact form. Then check the Core Web Vitals report in Google Search Console and run a PageSpeed Insights test on the homepage and your two busiest practice area pages.
Is a separate mobile site better than responsive design?
For most law firms, no. Google calls responsive design the easiest pattern to implement and maintain. Separate mobile URLs need extra redirect and header work, and content tends to drift between the two versions over time.
