Google’s free Mobile-Friendly Test tool, the one where you could paste in any URL and get an instant pass or fail, has not existed since December 2023. If you want to know today whether your website actually works on a phone, the current path is Google’s PageSpeed Insights or Lighthouse in Chrome DevTools, combined with a short manual check on a real phone. It takes about the same amount of time as the old test did, but it shows more: not just whether a page is technically mobile friendly, but how fast it loads and how stable it feels while doing so. The sections below cover why this still matters, how to run the test today, and why desktop still deserves attention for a home services business in the US.
Why Google made the mobile version the standard in the first place
As of October 2023, Google considers its mobile-first indexing rollout complete, a transition that actually started back in 2016. In practice, that means Googlebot visits your site using a smartphone user agent, and whatever it finds there determines indexing and ranking, not the desktop version. If the mobile view is missing content that exists on desktop, say a service area list or a paragraph trimmed for space, Google is working from that shortened version by default. For a home services business, that means the phone view of your site isn’t a stripped-down afterthought anymore. As far as Google is concerned, it’s the only version that counts.
How to test it now that Google’s old tool is gone
Three steps give you a reliable picture:
- PageSpeed Insights (pagespeed.web.dev): enter your URL and pull the mobile report. Alongside load time, it flags specific issues like tap targets that are too small or text that’s hard to read without zooming.
- URL Inspection in Google Search Console: shows under “Crawled as” whether Google is actually indexing the page via its smartphone crawler, plus a rendering preview of what the bot sees.
- A real test on your own phone: open the site in at least two browsers (Chrome and Safari at minimum), fill out the contact form, tap the phone number, open the map to your service area. Automated tools miss usability problems that show up immediately in real use, like a dropdown menu that’s nearly impossible to tap accurately.
For more technical detail, Lighthouse in Chrome DevTools (right-click, Inspect, Lighthouse tab) adds a fuller breakdown, including Core Web Vitals: the metrics Google uses for load speed, visual stability, and responsiveness.
What “mobile friendly” actually means technically
Responsive design, where the layout adjusts automatically to screen width, is the baseline, but it isn’t the whole story. Four things determine whether a page actually works in practice:
| Criterion | How to spot it |
|---|---|
| Viewport set correctly | Page scales to screen width immediately, no manual zoom needed |
| Tap targets large enough | Buttons and links are easy to hit with a thumb without misfiring |
| Readable font size | Body copy reads clearly without zooming in, usually 16px base or larger |
| No horizontal scrolling | Full page width stays visible, nothing gets cut off |
Website builder templates that were originally designed for desktop and later retrofitted as “responsive” tend to fail on one of these points specifically, like a pricing table that runs off the edge of the screen on a phone, or a contact form with fields packed too tightly to tap accurately.
Why desktop still matters for a US home services business
A lot of contractors assume that since most people search on their phones now, the website should be built mobile-first and nothing else. The traffic numbers for the US tell a more balanced story. StatCounter put US desktop traffic at roughly 55% in July 2026, with mobile at about 45%, meaning desktop still holds a real lead here, unlike many other countries where mobile traffic dominates outright. In practice, that means a homeowner might find your business on a phone while searching from the job site or a friend’s recommendation, but often opens the estimate you emailed, compares contractors, or reviews the contract on a laptop at the kitchen table, sometimes with a spouse looking over their shoulder. A site that looks great on a phone but shows up on a laptop as an oversized mobile layout with awkward white space quietly loses credibility with exactly the audience deciding on a bigger job.
Which pages to test beyond your homepage
Most business owners, if they test anything at all, only check the homepage and consider the job done. That’s rarely where the worst problems actually live, since homepages tend to get the most design attention. Three other page types matter more:
- The contact or estimate-request form: Can every field be tapped without misfiring, does the right keyboard pop up automatically (number pad for a phone field, email keyboard for an address field), and does the submit button stay visible without scrolling past a wall of fields first?
- Service pages with pricing tables or comparison charts: Tables comparing service tiers, common on home services sites, often run off the edge of a narrow screen unless they’ve been specifically rebuilt for mobile.
- The navigation menu itself: Does it open reliably with one tap, close just as easily, and keep key items like “Contact” or “Emergency Service” visible in the expanded menu instead of buried in a long list?
A test that only covers the homepage misses exactly the pages where a visitor actually turns into a lead.
What this means for your own website
For home services businesses, three elements tend to fail a real-world mobile test more often than anything else: a click-to-call button placed high enough to see without scrolling, a service-area map that opens directly into the phone’s navigation app instead of a static image, and a contact or estimate-request form with as few required fields as possible so it’s realistic to fill out with a thumb. How load speed itself affects bounce rates and lead volume is covered in more detail in why a slow website costs you customers. The connection between the mobile version of a site and Google ranking isn’t a side note either, it ties directly into how long it takes for a new website to rank on Google, since mobile-first indexing is exactly where that process starts.
Finding gaps after your own test doesn’t necessarily mean starting over. Often the fix is targeted work on tap targets, the form, and load speed rather than a full rebuild. Sites built from the ground up to be technically lean and to serve both device classes from the same structure, instead of a desktop design patched into a mobile one after the fact, tend to run into this problem less often. Businesses looking to rebuild along those lines can start at website as a service.
A roofing contractor whose site loads fine on a phone but ends with a tiny contact form and a call button buried at the bottom of the page is losing real inquiries, independent of how well the site ranks. With today’s tools, the test itself takes under ten minutes, and fixing the most common problems usually doesn’t take much longer once you know exactly what to look for.
