A study points out that online retailers have slowed the adoption of Google Checkout online payment option to the advantage of other competitors, such as Bill Me Later and PayPal.

Of the 100 participants involved in the study, 37 percent of retailers provide alternative payment options. This is a 23 percent growth from the figure indicated by a study conducted by the same company in 2007. Bill Me Later ranks highest in the retailers' preferences, with 26 percent (up from 21 percent in 2007), as compared to PayPal which is used by 25 percent of retailers (up 19 percent from 2007) and Google Checkout, with 11 percent (up 1 percent from 2007 figures). Of all retailers, only 7 percent stated that they offer their customers all three payment methods.

A company representative cited by News Yahoo! states that since the Google Checkout launch in 2006, over 500,000 sellers have selected the service. Google Checkout users store their credit or debit card and shipping information in their Google Account and they can purchase at participating stores at the click of a button. Google Checkout charges 2 percent of each sale and 20 cents for every transaction. PayPal charges depend on the amount of purchase, starting with 2.9 percent on sales of more than USD 3,000.

The study was conducted by interactive marketing agency Rosetta.
