E-commerce Insights: Add the Fifth ‘P’ of Marketing

Google charges 2 percent plus $0.20 for each transaction, regardless of which underlying card consumers opt for.

I noticed two powerful and interesting twists to Google Checkout: free card processing and better ad placement. If the merchant advertises using AdWords, Google’s pay-per-click service, Google provides processing for $10 worth of sales for every $1 spent on AdWords. For many merchants, this effectively makes processing free.
