How Google’s Mobile-First Indexing Will Impact Your SEO

Google’s announcement that they will be transitioning to a mobile-first indexing model has major SEO implications. In this guide, we’ll break down what you need to know and how to prepare your website.

What is Mobile-First Indexing?

Mobile-first indexing means that Google will primarily use the mobile versions of websites to understand how to best show and rank pages in mobile search results. Some key things to know:

• Google will fetch and render web pages using their mobile user agents instead of desktop ones. This allows them to better understand the mobile experience.
• The mobile version of a site will have a more significant impact on rankings in mobile search results. Google sees this as betterserving mobile users.
• The desktop index is not going away, but updates will happen less frequently than the mobile index going forward.

Google’s goal is to ensure search results match what the user is likely to see on their device. This approach aligns with today’s reality, where over 50% of searches come from mobile.

How will this impact SEO?

There are a few main ways mobile-first indexing will impact SEO strategies:

Prioritize Mobile-Friendliness: If your site is not optimized for mobile, it risks lowered rankings. Use responsive design and test pages on multiple devices.

Ensure Strong Consistency: Content, headings, images, and more should match between desktop and mobile. Inconsistencies could confuse Google’s understanding.

Optimize for Speed on Mobile: Pages need to load faster on mobile networks to provide a good user experience. Use tools like PageSpeed Insights to test page speeds.

Consider the AMP (Accelerated Mobile Pages) format, which can help content load almost instantly on mobile. While not required, it may help engagement and rankings.

Structured Data is Crucial: With the primary focus on mobile, making sure things like product reviews, FAQs, and location data are marked up properly across devices is important.

Monitor Mobile Usability Signals: Things like click data, time on page and bounce rates should be analyzed separately for mobile and desktop to identify issues.

By ensuring your site meets these mobile-focused guidelines, you can help it thrive in Google’s new indexing model.

How to Audit Your Site for Mobile-First Indexing

To prepare for the shift, it’s important to thoroughly audit your website and identify any issues. Here are the key steps:

1. Check Mobile Friendliness

Use the Mobile-Friendly Test tool in Search Console to identify any issues like text being too small, tap targets too close together, etc. These must be fixed.

2. Compare Desktop vs Mobile Content

Thoroughly compare pages on both devices and versions. Headings, text, images and functionality should all match. Note any discrepancies.

3. Analyze Page Speed

Use PageSpeed Insights to audit loading speeds on both 3G and WiFi networks. Optimize code, images, remove unused files, etc to improve performance.

4. Validate Structured Data

Use the Structured Data Testing Tool to verify all relevant metadata, like products and reviews, is marked up consistently across devices.

5. Check links, Sitemaps & Robots.txt

Ensure internal linking and crawlability are not disrupted by redirects or errors on mobile. Sitemaps should include mobile URLs.

6. Monitor Search Analytics

When issues are fixed, check Search Console for improvements in url parameter handling and SCORE parameters for any inconsistencies cleared up.

By following these best practices to audit your site, you can identify and resolve any issues that could negatively impact your search performance in Google’s mobile-centric systems going forward.

“With the shift towards mobile-first indexing, having a great mobile user experience is more important for search than ever before.” – John Mueller, Google.
