Remapping Dynamic URLs to Static URLs can Increase Traffic

Our second case study has been brought to us by In this case study we explore what happens with all the URLs on a site are changed. In this case study the decision was made to change their URLs from dynamic URLs such as this one: to more user friendly static URLs such as this one:

The changes were completed on December 22, 2006. In addition to remapping the URLs, Plumber Surplus was careful to 301 redirect the existing URLs to the new ones. This was done on a URL by URL basis, using to parse the request and rewrite the URL.

The majority of the new URLs were indexed by Yahoo and Google within 2 weeks. MSN took somewhat longer. Within two months, rankings began to improve, and the number of indexed pages began to increase. Here are the detailed results:

Indexed Pages

Engine 11/1/2006 1/3/2007 3/1/2007
Google 38,400 85,600 62,200
MSN 597 959 2,068
Yahoo 10,633 22,560 30,581

Site Traffic

Date Visitors Per Day
11/1/2006 9,000
1/3/2007 12,000
3/1/2007 13,500

Note that Plumber Surplus did undertake other SEO activities during this timeframe, so it’s hard to credit all the search engine ranking and indexing improvements to this change alone. However, no major new links were obtained in this timeframe, and URL structure can influence search rankings.

Equally important, a massive URL move involving every page on the web site except the home page was completed without incident. Everything was resolved by the search engines in a matter of weeks. This is a clear example of how this should be done.

However, be aware that such massive moves do come with risk. There is no such thing as a risk free strategy when it comes to search engines, and your mileage may vary.
