A short guide to mobile-first indexing

The version of this that works is simpler than the version most people imagine. Everything we would tell a client about mobile-first indexing in the time it takes to drink a coffee.

Search work compounds slowly, which is why it gets abandoned about two months before it would have paid off. It is the sort of thing that looks like polish right up until it costs you an enquiry.

Why this earns attention

The mobile version of your page is the one that gets indexed. The cost of getting this wrong is rarely visible on the day it happens. The practical test is whether someone new to the project could tell, in a minute, that it had been handled.

How to approach it

Content hidden on mobile carries less weight. Small and consistent beats large and occasional here. The teams that stay on top of it are the ones who put it on a calendar rather than a wish list.

Common failure modes

Parity between mobile and desktop content matters. The teams that handle this well are rarely the ones with the biggest budgets. If two people in the business would answer this differently, that gap is the actual problem.

The short version

Technical fixes remove obstacles; content earns the position. Both are needed and they are not interchangeable. Three things worth confirming about mobile-first indexing before you move on:

• Someone can say what the current setup is without going to look
• Parity between mobile and desktop content matters — and you know whether that is true here
• There is a way to tell whether the last change to this helped

Pick the one that would hurt most if it failed, and start there.
