This is the duplicate URL problem. It’s possible to have different URLs that lead to the home page. Most websites have www and non-www duplication, which can result in a lot of unnecessary duplications for example :
The above URLs can lead to the page page. Some websites with different extensions lead to the same page, which can cause a potentially wasted link value and duplication.
To fix this problem, you should:
- Choose a single URL style from www or non-www and set your home page URL to http://www.aeserver.com or http://.aeserver.com, respectively. 301 redirect everything else to this URL.
- If you have different versions for tracking purposes, use a canonical tag to show the search engines which version you want to show in the search results.
- Make sure to link the correct version of your home page.
