Chapter 1: The Page Experience Update

Introducing the Page Experience Update

On June 15, 2021, Google rolled out the Page Experience Update, a search algorithm favoring pages that offer great user experience.

According to Google, the Page Experience Update includes a set of essential signals for delivering a good user experience.

Core Web Vitals (CWV)

Core Web Vitals are metrics that measure real-world user experience for loading performance, interactivity, and visual stability of the page. We will talk a lot about CWV since they are the main topic of this guide.


Ever since Google transitioned to Mobile-First Indexing, optimizing for mobile has become one of the most critical tasks for website developers and SEOs. With the Page Experience Update, having mobile-friendly pages became a requisite to rank well in Google.

You can check whether your pages are mobile-friendly with the Mobile-Friendly Test tool or the Mobile Usability report in Google Search Console.

HTTPS serving

Securing your pages with HTTPS is not only a good practice for SEO but a must to protect the data integrity of your website and your users’ personal information.

Follow Google’s guide to check whether your website’s connection is secure.

No intrusive interstitials

Avoid intrusive pop-ups that make content less accessible. Google considers intrusive interstitials those pop-ups that cover the main content or request user actions to access the main content.

Exceptions can be made for interstitials for legal obligations (e.g., cookie notices), login dialogs for publicly indexable content (e.g., content that is behind a paywall), and feasibly dismissable banners that don’t take too much space (e.g., app install banners).

For more on this topic, follow Google’s best practices to avoid intrusive interstitials.
