Site Speed and Purchase Friction

A slow page can interrupt a shopper before they see or use the product controls. Measure the actual mobile shopping path, then fix large assets or scripts that delay useful content and interactions.

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.
