What is Canonical issue in SEO ? - Kaushal - 04-08-2014 04:50 AM

I want to know about canonical issue. Please provide me detail with some examples.

Canonical is a tag which is placed in duplicate page issue like I have two pg A and B but by mistake A's content got repeat in B the I will insert canonical tag in page B. So that Google's crawler should move away by seeing canonical tag.

best example is the http://www.yourdomain.com vs yourdomain.com
both mean the same, but you want yourdomain.com to point to http://www.yourdomain.com

this also makes it so if you use google webmaster tools, you dont have to keep track of both of them.

Canonical issue is simply about duplicate content issue. Know more about it on this post: http://delasks.com/on-page-seo-techniques-what-is-url-canonicalization/

Canonical issue is the problem when a website url say http://www.yoursite.com are same urls. So, this can create issue which optimizing websites for search engine.

When a single page can be downloaded from different urls it is called canonical issue.

Canonical issue is of duplicate pages, if by chance your site 2 page same content and different urls but you can't redirect it so their using canonical tag. Canonical tag using in head section on your site.

Wow I can't believe how many wrong answers there are here. Sorry, but half of them are about 301 redirects. <--- wow.

One guy said it best tho... Ramesh. It's about duplicate content, and here is a way to explain it.

You have two pages which are almost entirely the same content for whatever reason.

Page A - has content about cars /pagea
Page B - has the same content about cars, but has a different URL. /pageb

Page A is what you want listed in Google and where you want the traffic to really go to.

So you set a canoncial tag on PAGE B... (the canonical tag lists page A) to say that Page A is the place the visitors and the engines should go.

Page A will get priority, and you are telling the search engines pretty much this:
"Hey, I have two pages with the same content, but I am setting the canonical URL to page A okay? This way I won't have any duplicate content issues."

Search Engine: "Okay thanks! We will make sure and list page A and not page B, thanks for letting us know, you won't have a duplicate content issue now."

There's your answer. Hope that helps.

if you have a same content at many web pages but the url is different then it is a canonical issue.
If you are using a same content then add a Canonical tag to page else google will penalize your site for spamming.

Mike Smith I agree with your answer. The answer which you have given is correct & you have given a very straight answer. Traffic to a site is divert only because of canonical issues which is not good for the websites.
