We've added a new report to the Shopify admin that will help merchants and Partners gauge and measure online store speed.
The new Online store speed report runs speed tests for merchants' home page and highest-traffic collection and product pages, and then combines each page’s Google Lighthouse speed score into an overall score. It also provides a comparison of how a merchants store’s speed compares to similar online stores.
The Online store speed report will roll out to all merchants over the coming weeks. You can learn about how the speed score and ranking are calculated and how you can help merchants improve their speed in the Shopify Help Center.
