HI friends, i want to know about the canonical error? How this error create and how it is affect the website? Please give me answer bcoz i cant understand this error.
Canonical issue can affect your ranking in google search engine. This problem occurred only in google search engine. As per google webmaster guideline, a web site with www & without www is treated two individual web sites with same content. So in this case google takes one web site as a duplicate content. It affects not only your ranking also affects your web site page rank. So you need to write a specific code so that when you enter domainname.com,
Canonical error is when you have more than one URL for the same exact page. For example, http://www.domain.com and http://domain.com. You need to define which URL is your preferred URL for tht page by using the rel="canonical" code. You need to to add this to the <head> section of the non-canonical version of the page. If you are using Wordpress, you can use canonicalization plugins, although if I remember correctly, Wordpress automatically corrects canonical errors now. Hope that helps. Have a good day!
Canonical actually isn't not an actual error, but this particular tag defines that the content on the page is taken from other URL. When a search engine spiders crawls your canonicalize URL, it will redirect spiders to that URL.
When your home page opens with both "http://www.site.com" and "http://site.com" is known as canonical error. Sometime Canonical URL (best URL version) is also referred as "Preferred Domain".
when your site home page found on both "http://www.example.com", "http://example.com" and "http://www.example.com/index" it is called canonical error. it can be solved easily using .htaccess. You need to place this tag< rel="canonical " href="http://www.example.com"/> into other non canonical pages. this to show the search engine that this is the original version.
Canonical error is also define as duplicacy in somwhere in term SEO, due to 2 other different urls one with www and another without www. It an be solved in google webmaster Configuration>>Setting.
Google can reach to your web page through different URLs, this may create a confusion of duplicate content for search engine then its errer called canonical error.
when, your site page is opening with www. and without www its just canonical error.... in my view this is good for site.
