Speed Check
Speed check lets you test how fast the Shopvid widget loads on your actual storefront, measured from a real browser session — not a simulation. Use it to spot performance issues before your customers do.
Prerequisites
- The Shopvid widget is installed on at least one page in your theme
- App embed is enabled in your Shopify theme settings
Steps
Step 1: Open the Dashboard
In the Shopvid sidebar, click Dashboard. Scroll to find the Speed check card.
Step 2: Select a page to test
In the Page to test dropdown, choose which page type to run the test on: Homepage or Product page. Pick the page where your widget is installed.
Step 3: Run the test
Click Start widget performance test. Shopvid opens your live store in a new tab, measures how the widget loads, then returns the results to the Dashboard. Keep the tab open until the test finishes.
Step 4: Read the results
Three metrics appear, each with a status badge:
| Metric | What it measures | Fast | Average | Slow |
|---|---|---|---|---|
| Widget load time | Total time for the widget to fully load | Under 1s | 1–3s | Over 3s |
| First render | When shoppers first see the widget | Under 500ms | 500ms–1s | Over 1s |
| Widget size | Total size of scripts and assets | Under 512 KB | 512 KB–2 MB | Over 2 MB |
Step 5: View test details (optional)
Click View details to see the browser environment captured during the test — connection type, browser, viewport, and exact timestamp. Useful if you need to report a performance issue to support.
Step 6: Run the test again
Click Run again to retest at any time — for example after making theme changes or optimizing your setup.
Tips
- Run the test on the page where most of your traffic lands for the most relevant result
- If the test times out, make sure the diagnostic tab finished loading and try again
- If you see Widget not detected, confirm the Shopvid widget block is added to the page you selected
