"Make sure it works on mobile" is the wrong sentence. It implies mobile is a thing to check at the end. A box to tick after the real design is done.
That hasn't been true for years. For most businesses, the majority of visitors land on the site from a phone. Mobile isn't a version of the site — it *is* the site.
What Mobile-First Actually Means
It doesn't mean "the desktop site, but smaller." It means the design decisions get made on a small screen first, then expand outward as the canvas grows.
That order matters. When you design desktop-first:

The Smell Test
Open your current site on your phone. Don't pinch to zoom. Don't rotate to landscape. Just hold it like a normal human and answer:
If you said no to any of those, your site is hostile to half your visitors.
What We Do
Every site we build is designed on a phone-sized canvas first. We make sure the hierarchy works on a screen the size of an index card before we even open a desktop view. Then we let the design breathe outward into tablets and desktops — which is the easier direction.
The result is a site that feels deliberate on every screen, not a desktop site bolted onto a phone.
Why It Matters Beyond Aesthetics
Google ranks sites based on the mobile experience. Visitors form trust judgments in seconds. If your site stutters, mis-scales, or hides the thing they came for, they leave — and they don't blame "their phone." They blame you.
Mobile-first isn't a design philosophy anymore. It's the floor.
