One of our clients has shared with us some interesting stats that make a strong case for both, single-page checkout and product reviews.
Single-page checkout (SPCO), as described by its name, makes it easier for online buyers to complete their transactions by reducing the standard multi-paged checkout process to one page. Our client’s shopping cart conversion rate went up from 57.3% to 75.5% after replacing their checkout process with SPCO.
The same client also saw increased conversion rates for products with user reviews than for those without the reviews. The chart below shows the delta between non-reviewed and reviewed products during the month of November 2009.
