Your speed score

Your speed score measures how fast your online store performs inthe Shopify test environment, based on Google Lighthouse performance metrics.

Your speed score is recalculated daily. Due to the way the score is calculated, your score might not change immediately after you make changes to your online store. If your store is new or password-protected, then youmight not have a score．

How your score is calculated

Your score is based on a weighted average of theLighthouse performance scoresfor your store's home page, your product page with the most traffic over the last 7 days, and your collection page with the most traffic over the last 7 days. Weights are based on multiple factors, including the relative traffic to each of these page types across all Shopify stores.

The online store speed score is an average of multiple days of Lighthouse performance scores. This is because performance scores can vary slightly between tests, and an average over multiple days better represents your store's day-to-day performance. If your store is new or you just removed the password page, then your score might be less accurate. To view the score for each page type, click on theSee how your score is calculateddrop-down.

Lighthouse reports are run on the mobile versions of these pages. This is because 60% of sales made on Shopify stores are from mobile devices.

If you don't have a collection page, product page, or home page, or a page type has no views, then the page's score is listed asNo data available．Your online store speed score is calculated using only the available pages and their weights. Your score is not negatively impacted.

What your speed score means

Your speed score can help you to understand your store's speed and itsperceived speedfor your customers.

A higher score represents an online store that’s fast for the wide variety of customers accessing it. Even a customer with a slow phone and poor mobile connection can have a positive buying experience.

A lower score represents an online store that might not be accessible to the full range of customers that want to make a purchase from your store.

A high Google Lighthouse score is hard to achieve, and becomes harder to improve as you achieve a higher score. Lighthouse compares your online store to all types of websites, many of which don’t offer the same functionality as an online store. To understand how your store is performing compared to other Shopify stores, view yourspeed ranking．You can then use your speed score as a measurement to help you to make your own online store better for your customers.

Speed score over time

TheSpeed score over timesection shows you how your speed score has changed over the selected date range. The section includes a chart that tracks your score over time and a table that lists your historical scores and app install or uninstall events.

The chart includes event markers, which represent an app being installed or uninstalled. These events might or might not impact your speed score. You can view a list of the apps that were installed or uninstalled by clicking on the event marker.

Using this section, you can identify app-related events that positively or negatively impacted your score and investigate them. For example, if your score declines after you install an app, then you should considerevaluating the appto decide whether the features the app introduces outweigh the impact to the speed of your store.

When the Online store speed report loads, the chart shows the last 7 days of scores. You can alter the date range using theDate rangepicker. Scores are recalculated at 9:00 am UTC. If you are missing the most recent score in your report, then you should check again later in the day.

You might not have a speed score for every day. Missing speed scores appear as gaps in the speed score chart and as an empty score (—) in the table. Learn about thefactorsthat prevent the speed report from running.

The Shopify test environment

Scores in your online store speed report might be different than scores you calculate using PageSpeed Insights, or Chrome DevTools. This is because the environment where the Lighthouse report is runimpacts the report results, and because scores on all platforms only represent a point-in-time measurement of your store's speed.

Lighthouse reports run on the Shopify test environment do not fluctuate based on common factors like internet connection speed, device processing power, browser extensions, or antivirus software. Because all Lighthouse performance reports used for speed scores are run using the same Shopify environment, we can accurately compare your score to that of other online stores on the Shopify platform.

Other factorsmight cause your score to change from day to day.
