We measured 186 local law firms across 32 US metros. Only 48% pass Core Web Vitals on mobile, and the culprit is the marketing stack a local firm bolts onto its homepage.
Key Findings
- 1.Across 186 local law firms measured in real-user field data, only 48.4% pass Core Web Vitals on mobile. Fewer than half of local legal sites pass.
- 2.The firms are responsive (96.2% good INP) and stable (91.4% good CLS), so the failures are not about interaction or layout jumps.
- 3.Loading is the weak point. Good LCP is 74.2%, the weakest of the three metrics, and the median firm paints its main content in 2.0 seconds.
- 4.More than a quarter of local firm sites (28.5%) have too little traffic to report a responsiveness score, a sign of how many small firms run lightly-visited sites.
- 5.The inversion is the story. In a separate national set the elite firms passed 77% of the time with light prestige brochure sites, while the local firm on a marketing template is the slower one.
- 6.The slowest local firms load in 5 seconds or more, driven by heavy homepage video and stacked marketing scripts, not by anything a visitor needs to see first.
Summary
You would expect the giant national law firm to run the heavy, slow website and the local attorney to run the simple fast one. The field data says the reverse. Across 186 local law firms we measured in 32 metros, fewer than half pass Core Web Vitals, while the elite national firms in our smaller, separate set pass more than three-quarters of the time. The small firm is slower than Big Law, and the reason is not prestige. It is the marketing stack the local firm bolts onto its homepage to generate leads.
For a local firm, the website is where a case begins. A potential client with an urgent problem, an injury, a DUI, a divorce, searches, taps a result, and decides in a few seconds whether to call. If the homepage is still assembling itself when they land, they are already back in the results looking at the next firm. In a market where a single case can be worth more than a year of hosting, speed on that first page is not a technical nicety. It is the intake funnel.
The measurements come from the Chrome User Experience Report, Google's record of how real visitors experience these sites on their own phones, across 186 local firms ranking in search in 32 US metros. The picture is consistent enough to name a single cause, and encouraging enough to fix without giving anything up.
What the data covers
The readings come from the Chrome User Experience Report, which records loading, responsiveness, and layout stability from the browsers of real prospective clients opening these firm sites on their own phones and networks, not from a synthetic lab run. The legal sample was built the way a prospect actually finds an attorney in Google: 186 local law firms that surface in the results for practice-area-plus-city queries across 32 US metro areas, benchmarked against a separate national comparison set of elite national firms.
This is a competitive-search set by design, not a census. It reflects the firms a prospective client actually sees when they open Google to compare attorneys in their city, which is the pool that decides who gets the consultation call; it is not an attempt to catalog every law firm website on the internet.
Passing Core Web Vitals requires clearing all three of Google's thresholds simultaneously at the 75th percentile of a firm's mobile visitors: main content painted in under 2.5 seconds (good LCP), interactions responding in under 200 milliseconds (good INP), and a layout stable enough to score under 0.1 on cumulative shift (good CLS). It is a strict all-three bar, and fewer than half of local firms clear it.
Fewer than half of local firms pass
Across the 186 local firms, 48.4% pass Core Web Vitals on mobile, near the web-wide average and well below what the big national firms manage. The failures are not about interaction or stability. Good INP runs 96.2% and good CLS 91.4%, both healthy. A firm's homepage responds to taps and holds its layout in place just fine.
The problem is loading. Good LCP is 74.2%, the weakest of the three metrics, and while the median firm paints its main content in 2.0 seconds, more than a quarter of firms load slower than that. A quarter of these sites also have too little traffic to register a responsiveness score, which reflects how many small firms run lightly-visited sites, and under the strict all-three rule those count as not passing.

Interaction and layout are fine. Loading is the lone weak metric, and it is a marketing-stack problem.
Why the local firm is slower than big law
Set the local firms against the elite national firms and the picture inverts. In a separate national set, 77% of the major firms passed, because an elite firm's site is a light prestige brochure: attorney bios, practice areas, and insight articles, and very little else. The local firm's homepage is a different product. Local legal is one of the most competitive lead-generation markets on the web, and the homepage reflects it.
It commonly carries a full-screen video background, a stack of marketing tags, a live-chat widget, a reviews feed, call-tracking scripts, and retargeting pixels, all loading before the content a visitor came to read. None of that is wrong to want. It is simply heavy, and it is what pushes loading past the passing line. The slowest local firms in the data load in 5 seconds or more, and the cause is consistent: a heavy homepage video plus a stack of marketing scripts. That is a fixable configuration, not a rebuild.
| Measure | Local law firms |
|---|---|
| Sites measured | 186 |
| Pass all Core Web Vitals | 48.4% |
| Good LCP (loading) | 74.2% |
| Good INP (responsiveness) | 96.2% |
| Good CLS (stability) | 91.4% |
| Median LCP | 2.0s |
| No INP data (low traffic) | 28.5% |
Elite national firms, measured separately, pass about 77%.

The elite firms are fast because their sites are light. The local firm can be just as fast and still run its full lead-gen toolkit.
What a local firm should fix first
For a local firm this is a competitive opening sitting inside a diagnosis. Your responsiveness is fine at 96.2% good INP and your layout holds at 91.4% good CLS. Loading is what fails, at 74.2% good LCP with a median of 2.0 seconds, and the slowest firms run to 5 seconds or more. That is a marketing-stack problem, not a design one.
The weight is specific and so is the fix. Defer the marketing tags and the live-chat widget so they load after the content, replace the full-screen homepage video with a static image or load it lazily, and compress the hero imagery. You keep the entire lead-generation toolkit; you just stop letting it block the first paint.
The inversion is the lesson. The elite national firms pass 77% of the time because their sites are light prestige brochures, while the local firm loses the tap by loading its lead-gen stack first. In a market where one intake can be worth more than a year of hosting, being the firm whose homepage appears before the client bounces back to the results is an edge worth taking.
