Matt Cutts recently reported about a new algorithm change coming to Google. This modification will affect sites using multiple URLs that represent one destination page. Sites that do not make the appropriate changes may be penalized within Google’s index.
Currently, Google examines sites with numerous URLs that denote one page. Heuristics then make a guesstimate as to which URL is the preferred or ‘canonical’ URL. According to Cutts, “Canonicalization is the process of picking the best URL when there are several choices, and it usually refers to home pages.”
For example, the following URLs all represent Metamend’s homepage:
- http://metamend.com
- http://www.metamend.com
- http://www.metamend.com/index
*Note: we are updating our site to use one generic domain name.
To keep things simple, Google no longer wants to have to perform the procedure of identifying the preferred URL. Google is suggesting website owners use one consistent URL to represent the destination page. For website owners that wish to keep multiple URLs, Google suggests 301 permanent redirects that point to the permanent URL. This way, users will be redirected to the appropriate page if they access a homepage by a secondary address. For example, users requesting, say http://metamend.com/, will be pointed to http://www.metamend.com/.
