Local website data · Plumbers · Los Angeles, CA
We run an automated check on the public websites listed for local businesses. Here is what it found for plumbing businesses in Los Angeles, CA, next to the national numbers for the same trade. No business is named.
| What we measured | Los Angeles | All U.S. plumbing |
|---|---|---|
| Loaded sites served over https | 95% | 96% |
| Loaded sites with no mobile viewport tag in the code | 14% | 17% |
| Sites showing a copyright year of 2023 or earlier | 39% | 25% |
| Listed website addresses that did not load on our latest check | 40% | 35% |
| …of those, confirmed down on a repeat check | 3 | 1,286 |
| For-sale, parked or placeholder pages | 1 | 386 |
"Did not load" is one automated check and includes addresses that no longer exist. A missing viewport tag is a code check: in real-phone tests we found about 38% of such sites still fit the screen, so it is a warning sign, not a verdict.
A quick self-check: open your site on your phone. If you have to pinch to read it, add
<meta name="viewport" content="width=device-width, initial-scale=1"> to the page's head, or ask whoever built it.
Type your business name and city and we build a free preview from your own public listing. No card, no calls. If you like it, it's yours for a one-time price plus monthly hosting, shown on the preview.
Listings come from open business data (Overture Maps, Foursquare open places, and some state and city license files). For each website address on a listing, our crawler fetched the home page once (Oct 28 to Nov 4, 2026), respecting robots.txt, and recorded whether it loaded, whether it used https, whether the HTML has a mobile viewport tag, and any copyright year shown. Addresses that failed were re-checked later; the confirmed count is shown separately. Business counts are listings in our data, not a census, and a business can be listed under more than one trade.
