1. What is Mobile-First Indexing?
Mobile-first indexing means that Google predominantly uses the mobile version of your website for indexing and ranking purposes. If a website has separate desktop and mobile versions, Google will prioritize the mobile one.
2. Why Did Google Implement Mobile-First Indexing?
Google's decision to implement mobile-first indexing stems from the shift in user behavior. As mobile search volumes surpassed desktop, Google needed to ensure its search results reflected this change. By prioritizing mobile-friendly sites, Google enhances user experience and ensures searchers find relevant and accessible content.
