What your customers are trying to do

Shoppers ready to buy want to buy.

A online store website usually has to handle a fast, trustworthy checkout, product pages that answer buying questions, email capture for repeat sales, product reviews and gift cards.

A fast, trustworthy checkout: every extra step at checkout loses some buyers.

Product pages that answer buying questions: size, fit, materials and delivery times decide the sale.

Email capture for repeat sales: repeat customers cost less to reach than new ones.

Product reviews: shoppers look for reviews from other buyers before paying.

Gift cards: gift cards add sales in gift seasons.

FAQ

Frequently asked questions

What does Website Speed Optimisation involve for a online store?

Speed optimisation finds what makes pages slow for real visitors and fixes it, measured against Core Web Vitals. For a online store, the work centres on product and category pages, shipping and returns and checkout speed.

What are Core Web Vitals?

They are measures of loading (LCP), responsiveness (INP) and visual stability (CLS). web.dev publishes the thresholds for a good experience.[1]

Why does our site score well in tests but feel slow?

Lab tests use one device and connection. Field data from real visitors can differ, and low-traffic sites may not have field data at all.[2]
