HelpCheck your store's speed
The Core Web Vitals page measures your store's speed on real customers' devices. You see whether pages load fast or slow, whether they respond right away when tapped, and whether the layout jumps around while loading.
You don't need to connect Google. EcomWeb records the numbers by itself when customers view your store.
See the three main metrics
- Go to Analytics › Core Web Vitals.
- Look at the three cards at the top of the page.
Each card is one of Google’s Core Web Vitals metrics:
- Largest Contentful Paint (LCP): how long it takes for the largest piece of content, usually a product image, to show. Good is 2.5 seconds or less. Poor is more than 4 seconds.
- Interaction to Next Paint (INP): the time from when a customer taps to when the page responds. Good is 200 ms or less. Poor is more than 500 ms.
- Cumulative Layout Shift (CLS): how much the layout jumps while loading. Good is 0.1 or less. Poor is more than 0.25.
The big number on a card is the 75th percentile (P75): 75% of views are as fast as this number or faster. A green number is good, yellow needs improvement and red is poor. Hover over the i icon next to the name to read a short explanation.
Below the big number are the percentage of Samples rated Good, the three marks P50, P90, P95 and the number of samples recorded. With few samples, the result changes easily.
On a phone, tap the menu icon at the top left to open the sidebar first.
Find what is slow
The three cards below split the data by By page type, By device and By browser. Each card has up to 10 rows, with the most samples at the top.
- Scroll down to the By page type card.
- Look at the green percentage at the end of each row, which is the Share of visits with good LCP.
- Find the page type with the lowest percentage, for example Product or Collection.
- Do the same in the By device card to see whether it is slow on phones or computers.
Change the time range
By default the page shows the last 30 days. The date picker on this page also has times.
- Click the date button at the top of the page, which has a calendar icon.
- Choose a preset, for example Yesterday.
- Click Apply.
After you edit your theme or change images, choose a range that starts on the day you made the change so you can compare it with before.
Frequently asked questions
Why does the page have no data yet?
Data only comes in when customers view your store. Views while your store is in Coming soon mode aren't counted. Views of a theme preview may still be recorded. EcomWeb only records a share of views, so a store with few visitors takes longer to get data.
Can Staff see this page?
Yes. This page has no revenue, so the Store Owner, Administrators and Staff can all see it.
Can I see which individual product page is slow?
Not yet. The page only splits by page type, such as home, product or cart, not by individual address.
