Mobile-Friendliness
Whether the site is usable and readable on a phone.
Analogy Mental model
Whether the restaurant has a ramp and a high chair. Not every guest needs them, and their absence tells every guest who the place was designed for.
In practice What you actually do
Responsive layout, tap targets of at least 48 pixels, body text at 16 pixels or larger, no horizontal scrolling, no dead technology. Test on a real mid-range Android device, because that is the hardware most of the audience is holding.
Where people get burned Pitfalls
Indexing is mobile-first, which means the phone version is the version being judged. Intrusive interstitials, the full-screen app download prompt especially, are both a ranking problem and the fastest way to lose the visit outright.
