With Mobile-First Indexing, Google now prioritizes the mobile version of a site for indexing and ranking.

What is Mobile-First Indexing? 

This change is in response to the increasing prevalence of mobile device usage for internet browsing.

In essence, Mobile-First Indexing reflects the search engine’s acknowledgment of the mobile-centric nature of modern internet usage and aims to ensure that search results are tailored to the majority of users who access the web through mobile devices. Website owners and SEO professionals need to optimize their sites for mobile usability to maintain and improve their search rankings under this new indexing approach.
