Mobile First Indexing

Term: Mobile First Indexing

Definition: Mobile first indexing refers to the practice of a search engine using the mobile version of a website’s content for indexing and ranking.

Alternative Names: Mobile-First Indexing, Mobile-First Strategy, Mobile-First Web Design


Expanded Explanation: With mobile first indexing, search engines – predominantly Google – will use the mobile version of a webpage for ranking and indexing. This is designed to reflect the majority of users who search the internet using mobile devices. Google will view the mobile version as the primary version of the site, even if a user searches from a desktop.

Benefits or Importance: With a significant proportion of internet users browsing on handheld devices, mobile first indexing ensures that your website provides a good user experience on mobile platforms, something that can help improve your search engine ranking.

Common Misconceptions or Pitfalls: A common misconception is that mobile first indexing means ‘mobile-only’. Despite the shift to prioritising mobile, Google still indexes and ranks both mobile and desktop sites.

Use Cases: Mobile first indexing is a vital consideration for any website aiming for better visibility on search engines, especially Google. It’s particularly crucial for e-commerce and online businesses where higher search rankings can directly impact sales and revenue.

Real-world examples:

Consider an e-commerce site with a desktop version and a less detailed mobile version. With mobile first indexing, Google would primarily reference the mobile version, potentially missing information only available on the desktop version. This example illustrates the importance of ensuring your mobile site is as comprehensive and user-friendly as your desktop site.

Calculation or Formula:

There’s no direct calculation or formula for mobile first indexing. However, it’s critical to ensure your site is mobile-friendly. Google provides a Mobile Friendly Test tool to check this.

Best Practices or Tips:

  • Ensure your mobile site contains the same content as your desktop site.
  • Use structured data on your mobile site.
  • Make sure your mobile site is accessible to Googlebot.
  • Site loading speed is critical, so optimise your content to load quickly on mobile devices.

Limitations or Considerations: While mobile first indexing is important, it’s not the only factor that determines your site’s ranking. Other SEO practices should also be followed.

Comparisons: Mobile first indexing can be compared to desktop first indexing, the previous method where Google primarily used the desktop version of a site for indexing and ranking.

Historical Context or Development: Google first introduced mobile first indexing in 2016, reflecting the growing trend of internet usage on mobile devices. Their process was completed in 2021, meaning all websites are now crawled and indexed by Google with a mobile first approach. Not all search engines have followed suit, however.
