Hello friends,

How To Fix URL Errors..?

Problem #1: Non-www and www Versions of Site URLs
There are a couple of things you need to do to fix this:

Decide which URL style you want to use, www or non-www.
Set up a 301 redirect so that any links to your non-preferred URL style will go to the right style. This way you don’t waste link value by splitting it between two URLs.
Set your preferred domain in Google Webmaster Tools so your search result listings are consistent with your style preference.
Make sure whenever you build links to your site that you use the preferred URL style.

Problem #2: Duplicate Home Page URLs
et your main home page URL to be http://www.mysite.com. 301 redirect everything else to this URL since it is the most basic (If your preferred URL style is non-www, then do http://mysite.com)
If you have to set up different versions for tracking purposes or some other reason, set a canonical tag to show the search engines which version you want showing up in the search results.
Make sure when you build links to your home page that you link to the correct version.

Problem #3: Dynamic URLs
If possible, make sure that your site is using SEO-friendly base URLs. It’s better to have a base URL that will lead to the content rather than a URL that relies on a parameter. For example: http://www.mysite.com/unique-product.html is much better than http://www.mysite.com/category.php?prod=123 where some generic category page is really the base URL.
Set a canonical tag that tells the search engines to use the base version of the URL. That way you can still use parameter URLs like http://www.mysite.com/unique-product...123&param2=423 to get your data, but the search engines will consider the basic version as the official one.
