Server Capacity: Make sure your host servers can handle the increased browsing speed. (This only applies to sites like m.domain.com that have their mobile versions on a separate host.)
Switchboard Labels: labels applied, you kazakhstan phone number library do not need to change this application. These should remain as they are.
With mobile-first indexing, there is only one index (the same index Google currently uses). The change to mobile-first index does not create a new “mobile-first” index or create a separate “mobile index” with the “desktop index” remaining active. Instead, it changes how content is included in the existing index.
Mobile-first means that the mobile version will be considered the primary version when it comes to how rankings are determined. However, there may be cases where the desktop version may be taken into account (for example, if you don’t have a mobile version of a page).
However, you’ll still want to track both, as you’ll potentially continue to see varying rankings between mobile and desktop search results. As it stands now, Google primarily uses the desktop site to determine rankings, but you still want to track mobile rankings because they vary from desktop rankings based on user behavior and other factors.
The primary use case I've talked about so far is that they will use the desktop site to determine rankings when there is no mobile version available.
For websites where the desktop version has additional ranking information (like backlinks), it is possible that this information may also be taken into account – but there is no guarantee that they will crawl or index the desktop version when they see the mobile device.
