A canonical issue is exactly that, an issue with your rel="canonnical", what's the issue?

Actually I have no much idea about it, and that didn't really answer my question.

Ok so read up on canonical (Wiki) or Complete Guide to Rel Canonical - How To and Why (Not) (Moz).

 

"A canonical link element is an HTML element that helps webmasters prevent duplicate content issues by specifying the "canonical" or "preferred" version of a web page as part of search engine optimization. It is described in RFC 6596, which went live in April 2012."

 

So if you have a canonical issue it could be;

 

  • You are using $_SERVER['REQUEST_URI'] to generate the canonical which would mean any old junk in the url will become the "preferred" version.
  • You have each filtered results page using it's own canonical url instead of using the unfiltered default view url.
  • You have set the main url as the canonical for every page; e.g. <link rel="canonical" href="http://yourdaomain.com/">.

These are the three most common issues with canonical.

A canonical issue arises if your website is crawled by search engine with different urls. If you put the html tag rel="canonical" search engine take only the url in tag as original one. So duplication can be avoided.

If a search engine is crawling your site under different urls then you should investigate why rather than slapping a canonical band aid on the problem. Don't forget Google implements a crawl budget, pointless wasting it on never ending paths.
