Back in July 2009, we looked at the top Comparison Shopping Engines by traffic. Here is an updated chart:

• Google Shopping – Free Program
• NexTag – CPC Program
• TheFind – Free Program
• Shopzilla – CPC Program
• Shopping – CPC Program
• PriceGrabber – CPC Program
• Bing Shopping – Free Program

Some notable changes in the Comparison Shopping world since last year: TheFind.com has seen tremendous growth and are now ranked within the top 3 CSEs. Since around one year ago Yahoo! Shopping, has been outsourcing their product listings to PriceGrabber. Bing Shopping is no longer offering cash back and can now be managed through the Microsoft adCenter portal.

Some other smaller but notable CSEs are:

• Become – CPC Program
• Pronto – CPC Program
• Smarter – CPC Program
• SortPrice – Flat Monthly Fee
