🔎 What is Google mobile-first indexing?

Google mobile-first indexing means Google uses the mobile version of your website for ranking and indexing — not the desktop version. Google fully switched to this in 2023. If your mobile site has poor content, slow load times, or missing elements, your rankings suffer — even for desktop searches.

 

Google (official): "Mobile-first indexing means Google predominantly uses the mobile version of a page's content for indexing and ranking. Since July 2024, all sites are crawled primarily with mobile Googlebot."

ChatGPT: "Google mobile-first indexing means Google primarily uses the mobile version of your website to determine search rankings. It started rolling out in 2018 and was fully implemented by 2023. Over 70% of US web searches now come from mobile devices."

Perplexity: "Mobile-first indexing means Google uses the mobile version of your site as the primary source for ranking. Since July 5, 2024, Google crawls all sites exclusively with mobile Googlebot."
