Google Checkout adoption is dropping.  Maybe they ought to start "searching" for ways to increase market share.  Maybe a globally patented PIN debit application from HomeATM would help...

The adoption of Google Checkout by online retailers is stalling, according to a study by interactive agency Rosetta.

The report states that 37% of 100 leading online retailers surveyed currently offer alternative payment methods, a 23% increase since November 2007.

Of those, Bill Me Later is most popular at 26%, with PayPal now nearly tied at 25%. Google Checkout showed a tiny increase from 10% in 2007 to 11%. Only 7% of the retailers examined offer all three methods.

“Even though it boasts high consumer confidence, Google Checkout is struggling in retailer adoption,” said Adam Cohen, a partner at Rosetta's consumer goods and retail practice, which conducted the study last month. “Adoption of the service started out very strong last year, but has stagnated in the last 12 months."

The discontinuation of incentives for retailers during the holiday season is likely to negatively impact Google Checkout adoption on an ongoing basis, he said.
