Introducing Publisher Ads Audits for Lighthouse v1.2.0

August 31, 2020 RMags Mall 0 Comments

Today, we're announcing the general release of Publisher Ads Audits for Lighthouse v1.2.0. The major highlights of this release are:

• A new cumulative ad shift metric
• Support for auditing AMP pages (thanks to @adamsilverstein)
• Updates to support Lighthouse 6.0

A number of smaller enhancements and bug fixes are also included. For complete details, see the changelog on GitHub.

Measuring the impact of ads on the user experience

The new cumulative ad shift metric is the first publisher ads audit aimed at measuring the impact of ads on Core Web Vitals metrics. In particular, this metric provides insight into how ads affect the stability of your page's layout. To learn more about how ads affect layout stability and steps you can take to address this, see our article on minimizing layout shift with GPT.

The APIs for measuring layout stability are new and still evolving, so it's not currently possible to attribute layout shifts to ads with 100% accuracy. We'll be updating this audit as these APIs mature, so scores may change over time.

Try it out and let us know what you think

Publisher Ads Audits v1.2.0 is available to use right now. You can try generating an updated report from the web app, or grab the latest CLI release from GitHub or npm to run locally. Updates to the Chrome DevTools version will land in Chrome Stable with the Chrome 87 release (mid-November).
