## What you need to know

### What should you inspect first?

Load a product page on a typical phone connection and check when the photo, price and Add to Cart control become usable. Large original photos may add delay even if they look good; check when interactive elements respond, not just when the page looks loaded.

### Can apps slow the page?

Extra tracking, popups, reviews or chat tools can add code. Check each installed app's purpose and impact before removing something customers genuinely use.

### How can rich content and speed coexist?

Use appropriately sized images, load below-the-fold media when needed and avoid blocking the main purchase controls. Verify the experience after changes; a faster score alone does not prove more sales.

### What to check in your store

Measure a real product page, remove one confirmed source of delay in a test environment and repeat the full buying path before publishing.

## Frequently asked questions

### Does speed affect every store equally?

No single number predicts a purchase. Treat speed as a usability issue and compare it with the page's other barriers before deciding it is the primary cause of low conversion.

### Where do I check performance settings?

Use current performance guidance and measure real pages before and after each change without breaking the purchase path.
