How to Use Google Chrome to Assign Fast Pages on Mobile

Every web developer hopes to provide users with the best possible experience. What epitomizes a “good experience” will vary from developer to developer. On Google, a “good experience” comprises meeting or exceeding all metric thresholds for its Core Web Vitals. Impressing Google is what will deem your website a “fast page.” Here’s how it works.

What is a Fast Page?

The fast page label on a website helps users identify high-quality user experiences as they browse. The first of the guinea pigs are links on the context menu for Chrome on Android, wherein users can long-press on a link to determine whether a page is responsive and reliable. Soon, fast page linking will roll out onto Chrome 85 Beta.

Google creates fast page labels according to real-world historical data. If similar URLs match up, Chrome displays a fast page badge. If a website doesn’t present enough historical information, Google evaluates its performance based on its website host.

You can determine whether your website qualifies for a fast page label by navigating to chrome://flags, enabling “context menu performance info and remote hint fetching.” When the feature makes its final appearance on Chrome 85, users can allow fast page labeling on Lite Mode or by switching on “make searches and browsing better.”

What Happens When a Site Fails a Core Web Vitals Assessment?

Today, less than 15% of websites qualify for a fast page label. According to a recent study, only a few websites are optimized well enough to pass a Core Web Vitals assessment. In most cases, thousands of websites meet the benchmark for one or two vitals but often miss the final third mark.

Core web vitals and their corresponding metrics include:

  1. Largest contentful paint (LCP): This measures the speed at which a page can load its primary content. It should load within 2.5 seconds.
  2. First input delay (FID): This measures the speed at which a user can interact with the page upon opening it. This should occur within 100 milliseconds.
  3. Cumulative layout shift (CLS): This measures how often users come across a sudden layout shift. A successful page should maintain a CLS under 0.1.

Of the metrics most mobile web pages pass, FID holds a standing of 90%. Less than half tend to pass LCP and CLS assessments. Passing each evaluation is vital for web developers on the hunt for a fast page label, chiefly because Google’s upcoming algorithm update will turn core web vitals into ranking signals.


With plenty of time to prepare for the 2021 algorithm update, site owners have ample time to seek online advertising business tips in preparation. As Chrome 85 is deep into its public beta testing stage, now is the best time to enhance SEO efforts and rewire your mobile site infrastructure.
