CPC Strategy did a study based on the (1) overall traffic driven, (2) conversion rate, (3) Cost of Sale (COS) or Marketing $, (4) CPC Rate, (5) Responsiveness, and (6) Merchant tools; and ranked top 10 major comparison shopping engines (CSEs).

CSEs Conversion Rates by Industry

There are more than a dozen shopping comparison engines that a merchant can use to list products for sale. Listing products on CSEs that operate on the Cost-Per-Click model is a bit risky if the conversion rate is not monitored, as improperly generated feed files could result in wasting a lot of money on advertising products that do not convert. Traffic and conversion analysis is the key to optimizing data feed files for comparison shopping engines. While researching for data feed optimization, I came across an interesting report from Channel Advisor on "average" conversion rates for each CSE by industry. If your CSE result falls below the average shown below, your feed file needs optimization.

Nextag Optimization

Nextag is one of the leading shopping comparison engines (CSE) existed since 1999. It offers a true price comparison by providing an overall price comparison including shipping and tax based on the shopper's geographic location. According to Channel Advisor, Nextag held an 18.2% market share in June 2010 in the shopping comparison market with over 17 million visitors each month. Research also shows as many as 45% of all shoppers use shopping comparison engines to find the best price before committing to purchase a product.

Become.com Optimization

With the Christmas shopping season just around the corner, we've examined become.com's performance. become.com is a new shopping portal we've just added to our marketing campaign so we are required to look at its performance. In September 2010, we received 1018 clicks from Become and had only 2 sales, resulting in about 0.2% conversion rate which is an extremely low conversion rate. We've contacted the become.com and received a free consultation from them on how we can improve our conversion. Here is the summary of the conference call.

How do I setup an ecommerce website?

Setting up an e-commerce website is a little more involved than setting up a personal homepage. The basic domain and web hosting setup are identical, but the e-commerce website requires a few additional components to offer credit card processing and a secure checkout process. You may also use a 3rd-party hosted e-commerce application, but this article discusses the procedure for creating a standalone website built from a shopping cart application.

How to create a 301 redirect?

As described on URL Canonicalization article we published in March, having a unique URL for each webpage is important in improving your "Pagerank". Canonicalization is accomplished by redirecting non-standard web pages to a preferred ("standard") webpage. There are a number of ways to redirect a webpage, but 301 (HTTP/1.1 Status Code, "Moved Permanently") redirect is the search engine-friendly method that passes the PageRank and search engine ranking status from the old to a new page. Here is an example of how 301 redirects can be implemented in a LAMP (Linux/Apache/Mysql/PHP) environment.

URL Canonicalization

One of the first things discussed when beginning an SEO project is URL canonicalization. You may argue that the impact of having multiple URLs resolving to the same page may not have a huge effect on SEO (if you use it consistently internally), but it certainly doesn't hurt to normalize the URL so that only one URL serves a single webpage. Implementation is not too difficult for most webmasters, and there is a piece of evidence that URL canonicalization will have a positive effect on your SEO effort. You may use one form (www or non-www) of Url for all your internal linking, but you cannot guarantee that others will do the same on 3rd-party websites.
