SEO Problem: WWW vs. Non-WWW URLs
This blog entry was posted on March 9, 2011.
Many websites today still allow visitors to enter from either the www or the non-www version of their URL. As far as the search engines are concerned these are two different URLs, each with their own link popularity and different rankings on the search engines. This is a definite rankings killer that is easy to fix.
Test your own website. Go to your site and it will either be http://www.yourwebsite.com or it will be http://yourwebsite.com. Try and go to the other version by typing it into your address bar. It should automatically redirect back to the original version. If it doesn’t, you have a canonicalization problem.
This is easy to fix using a simple 301 redirect.
The search engines will treat these www vs. non-www versions as separate URLs. Each will likely have a different number of indexed pages, a different number of back links and possible a different Google PageRank.
The real problem that occurs is that your back links will sometimes be to www version and sometimes be to the non-www versions. This divides up your link juice and lowers your website’s overall rankings.
Did I mention that this is easy to fix?
- If your website is on an Apache Linux web server, then add a redirect into the HTaccess file. More instructions
- If your website is on a Windows IIs web server: More instructions
- Add a 301 redirect into your ASP code: More instructions
