Google has indexed and ranked the mobile version of your site, not the desktop version, for years now — a fact that surprises a lot of business owners who still check their own site on a laptop and assume that's what matters. Here's what mobile optimization actually covers.
Page speed on an actual phone, not a fast office wifi connection
Mobile networks are slower and less consistent than the connection you're probably testing on. A page that loads acceptably on office wifi can be genuinely slow on LTE — test on an actual phone, on cellular data, not just resizing a browser window on a desktop.
Tap targets, not click targets
A button or link that's easy to click with a precise mouse cursor can be genuinely hard to tap accurately with a thumb. Buttons and menu items need real spacing and a large enough tap area, or visitors mis-tap and bounce.
Navigation that actually works, not just resizes
A menu that looks fine collapsed into a hamburger icon can still be broken in ways that only show up on a real device — we recently found and fixed exactly this on our own site: a mobile dropdown menu that opened correctly but had no way to scroll to see everything inside it, because the container had no scroll behavior set for a phone-sized viewport. It looked fine in a resized desktop browser and only failed on an actual iPhone. That's the general lesson: resizing a desktop browser window is not the same test as an actual mobile device.
Text that's readable without zooming
If a visitor has to pinch-zoom to read your body text, the font size is wrong for mobile. This is a basic, easy check that a surprising number of sites still fail.
Forms that are actually fillable on a phone keyboard
A contact form with tiny input fields and no appropriate keyboard type (a phone number field that doesn't bring up the numeric keypad, for example) creates friction at the exact moment you're trying to capture a lead.
Why this matters for local search specifically
Most "near me" and local searches happen on a phone, at the moment someone needs a service — which means a broken mobile experience costs you exactly the highest-intent traffic you're trying to capture. Google's local ranking also factors in mobile page experience directly, so this isn't just a UX nicety, it's a ranking factor.
