Mobile-first indexing is currently rolling out across the web and Google is aware that many webmasters are still a little confused about what it means for them. So the search giant has attempted to clear up some of the confusion in a Twitter thread created last week.
You can see the thread for yourself by clicking here or on the embed below, but we’re going to cover all of the key points in this summary and remind you exactly what mobile-first indexing is (something Google doesn’t clarify in the Twitter thread).
What does Google have to say about mobile-first indexing?
We’ve seen great presentations & posts on mobile-first indexing, it’s awesome to see all the details (thanks, @aleyda @jenstar @alexisksanders @dawnieando @badams + others)! There are only a few things we’ve sometimes seen confusion about, so we thought we’d clarify them.

There are seven key issues Google seems to think webmasters are having with mobile-first indexing. Here’s what the search giant wants to tell you:
URLs in search
With mobile-first indexing, we index the mobile version. When we recognise separate mobile URLs, we’ll show the mobile URL to mobile users, and the desktop URL to desktop users – the indexed content will be the mobile version in both cases.
The total number of crawled URLs a day generally won’t change, but the balance will shift from mostly desktop to mostly mobile crawls. During a switch-over to mobile-first indexing we may temporarily crawl more as we re-index everything.
Unfortunately, it looks like we’re currently still not showing a cached page for many mobile-first indexed sites. This is a bug, not by design, and should get resolved over time. It’s just the UI, it doesn’t affect crawling, indexing, or ranking.
Speed and mobile-first indexing
The mobile speed update in July is independent of mobile-first indexing. Fast sites are awesome for users, especially on mobile, since devices and connections there tend to be slower than with desktops.
Mobile website UIs
Using ‘hamburger-menus’ and ‘accordions’ on mobile websites is fine.
Neither mobile-friendliness nor a mobile-responsive layout are requirements for mobile-first indexing. Pages without mobile versions still work on mobile, and are usable for indexing. That said, it’s about time to move from desktop-only and embrace mobile.
The mobile-first index doesn’t change anything for ranking other than that the mobile content is used. While mobile-friendliness is a ranking factor on mobile, being in the mobile-first index is not.

What exactly is mobile-first indexing?
We feel most of the confusion about mobile-first indexing disappears once you know exactly what it is – especially when the majority of sites are going to be unaffected. So let’s chip in with our own attempt to clear up the mobile-first indexing confusion by explaining what it is.
Until recently, Google has used the content from the desktop version of pages to crawl, index and rank pages for all queries. The problem is, there are a number of websites now that run separate mobile and desktop versions of the same pages and this has caused some issues now that the majority of Google traffic is mobile.
Mobile-first indexing means that when Google detects separate mobile and desktop versions of the same pages it will now use the mobile version by default and then revert to the desktop version for users who are searching on computers.
This means you won’t be directly affected by mobile-first indexing, unless you have separate mobile and desktop pages. This is true for the majority of sites across the web and Google itself recommends using responsive design to deliver single pages across multiple devices – something that won’t be affected by mobile-first indexing because there’s only one version of your content.
There is a chance you’ll see some fluctuation for certain pages if there’s any change to the results around you but it’s unlikely anything drastic will happen.
If you’re running separate mobile and desktop versions of the same page anywhere across your site, then you’ll want to follow Google’s best practices for mobile-first indexing. Above all, check that your links and canonical tags are in order, aim to provide the same content across both versions and make sure you have structured data present on both pages.
