What is the Best Comparison Shopping Engine?

Best shopping engines of 2012

CPC Strategy compiled data from more than 100 online retailers of varying size, approximately 4.2 million clicks and 8 million in revenue to determine the best comparison shopping engines online.

Comparison shopping engines include websites such as Pricegrabber, Nextag, Amazon Product Ads, Shopping.com, Shopzilla and Google Shopping.

In the study we analyze the best shopping sites for ecommerce merchant traffic, revenue, conversion rate, cost of sale, and cost per click rates, and total them to determine the heavy weight champion CSE.

Below is a brief overview of the Best Comparison Shopping Sites Report in 2012:

Overall Winners

Best shopping engines of 2012

Top 10 CSEs 2012

#1: Google Product Search (Soon to be Google Shopping – PAID – more info on that here)*

Google Shopping is the reigning top CSE for both Q1 2011 and Q1 2012, and has been for some time. Although Shopzilla beat out Google for overall traffic in 2011, and Amazon Product Ads nosed its way to the top spot for 2012, Google consistently generates a large amount of traffic, and dominated in both quarters for overall revenue.

#2: Nextag

Nextag brought home the second spot for overall CSE quality for the second year in a row and secured the top spot among the paid comparison shopping sites for 2012. While Nextag’s overall traffic decreased from last year, it is still the second largest revenue driving engine (after Google), for both 2011 and 2012. Nextag also significantly improved in terms of conversions and cost per click (CPC) rates for 2012.

#3: Pricegrabber

While Shopzilla took the top engine ranking spot for 2011, Pricegrabber nosed out the engine in Q1 2012. Although Pricegrabber’s COS and CPC rates decreased, traffic and revenue stayed fairly constant for both quarters.

Top Converting Sites

Shopping engines with the best conversion rate

#1: Google Product Search

Google Product Search was the second highest traffic generating engine for 2012, and the largest source of revenue for merchants. Consequently, for both 2011 and 2012, Google took home the gold for Conversion Rate in our rankings.

#2: Nextag

Right behind Google in revenue, Nextag is the second highest converting engine for merchants in 2012.

#3: Pronto

Although a smaller engine, Pronto packs a strong punch for merchant conversions, rounding out the top 3 engines for conversion rate.

Best Cost of Sale (COS) Sites

comparison sites with the best cost of sale

#1: Pricegrabber

Following the free CSEs, Pricegrabber got the top spot for best engine in the cost of sale (COS) category. It is also among the engines which decreased in overall COS from 2011 to 2012.

#2: Nextag

Although Nextag’s COS actually increased for 2012, it is still the second best choice for shopping engines for COS.

#3: Shopping.com

Rounding out the list, Shopping.com beat out Amazon Product Ads for the third lowest COS engines.

Movers and Shakers for 2012

Shopping.com bumped its way up to the fourth overall engine ranking spot for 2012, formerly having come in 6th.

Pronto went from last in the overall rankings to 7th place for 2012.

Engine Spotlight: Amazon Product Ads

Amazon Product Ads is one of the newer CSEs on there so it’s seen the most growth in recent years. Q1 2012 saw significant increases in traffic for Amazon Product Ads, and also a bump in revenue. Although the conversion rate for Amazon Product Ads decreased from Q1 2011 to Q1 2012, the influx of merchants listing on the program, increasing competition with one another is most likely the cause for the decrease in conversions.
