AMP Page Experience Guide

Analyze your AMP page

The AMP page experience guide is a tool that shows AMP developers how their AMP pages are performing against the Google Search page experience ranking signal, and provides actionable feedback on how they can improve. If we aren't able to provide you with actionable insights please use the available prompts to file an issue on GitHub so our team can help you understand how your AMP pages can be improved. We use publicly available APIs such as PageSpeed Insights, Safe Browsing, and Mobile-friendliness Test.

Core Web Vitals

Core Web Vitals

Core Web Vitals measure the quality of user experience on all web pages. They are a subset of Google's Web Vitals, an initiative to provide unified guidance for delivering a great web experience. Learn more.

Field testing highlights performance factors that lab tests may overlook. RUM is the only way to measure how your site performs for your users. Learn more.

Lab tests allow you to test new features before they're released to best ensure no performance regressions. Learn more.

Opportunity to improve is the difference in scores for the AMP page provided on origin and its cached counterpart. A status of "None" is reported if the origin page is already performing comparably than its cached counterpart, whereas a status of "---" is reported if there is not any data available about the cached page.

Loading speed
LCP:

Largest Contentful Paint | LCP

Loading speed is measured by Largest Contentful Paint (LCP), the metric reporting the render time of the largest image or text block visible within the first viewport.

User experiences are categorized as follows:

  • Good: Less than 2.5 seconds,
  • Needs Improvement: Between 2.5 and 4 seconds,
  • Poor: Above 4 seconds.

Interactivity
FID:

First Input Delay | FID

Interactivity is measured by First Input Delay (FID), the metric reporting the time from when a user interacts with a page, such as tapping a button, to when the browser is able to process that event.

User experiences are categorized as follows:

  • Good: Less than 100 milliseconds,
  • Needs Improvement: Between 100 and 300 milliseconds,
  • Poor: Above 300 milliseconds.

Visual stability
CLS:

Cumulative Layout Shift | CLS

Visual stability is measured by Cumulative Layout Shift (CLS), the metric reporting the layout shift scores during the lifespan of a page. Each time a visible element changes its position unexpectedly, the page's layout shift score worsens.

User experiences are categorized as follows:

  • Good: Less than 0.1,
  • Needs Improvement: Between 0.1 and 0.25,
  • Poor: Above 0.25.

Interactivity
TBT:

Total Blocking Time | TBT

Interactivity is measured in lab environments by Total Blocking Time (TBT). This lab metric reports the load responsiveness and helps quantify the severity of how non-interactive a page is prior to it becoming reliably interactive.

User experiences are categorized as follows:

  • Good: Less than 300 milliseconds,
  • Needs Improvement: Between 300 and 600 milliseconds,
  • Poor: Above 600 milliseconds.

Safe Browsing

Safe Browsing

Google's Safe Browsing technology finds thousands of new unsafe sites every day. Many are URLs of legitimate websites that have been compromised. Ensure your site's users are safe. Learn more.

To run the test directly, use Google's Safe Browsing site status.

HTTPS

HTTPS

HTTPS helps prevent intruders from tampering with or listening to communications between your websites and your users' browsers. You should always protect all of your websites with HTTPS, even if they don't handle sensitive communications. Learn more.

Mobile Friendliness

Mobile-friendliness

Having a mobile-friendly website is a critical part of your online presence. In many countries, smartphone traffic now exceeds desktop traffic. If you haven't made your website mobile-friendly, you should! Learn how.

To run the test directly, use the Google Search Console Mobile-Friendly Test.

Intrusive Interstitials

Intrusive interstitials

Intrusive interstitials block the content users want to see. Avoid frustrating users and make your site accessible. Learn more.
