  • At times when an article has been syndicated on your website, you can place a syndication tag.

    1. 1. All About HTML Tags Created By: Shalaka Pawar, APM, Search Engine Optimization @Convonix
    2. 2. http://www.example.com/product.php?item=swedish-fish http://www.example.com/product.php?item =swedish- fish&trackingid=1234&sessionid=5678http://www.example.com/product.php?item=swedish-fish&category=gummy-candy
    3. 3. Place in the <head> section <link rel="canonical" href="http://www.example.com/product.php?item=swedish-fish" />http://www.example.com/product.php http://www.example.com/product.p?item=swedish-fish&category=gummy- hp?item=swedish-candy fish&trackingid=1234&sessionid=5678
    4. 4.  Is rel="canonical" a hint or a directive Its a hint that Google honors strongly. This tag is taken into preference along with other signals Google considers Can I use a relative path to specify the canonical, such as <link rel="canonical" href="product.php?item=swedish-fish" /> Yes, relative paths are recognized as expected with the <link> tag. Also, if you include a <base> link in your document, relative paths will resolve according to the base URL.
    5. 5.  Is it okay if the canonical is not an exact duplicate of the content Slight differences are accepted. E.g. a sort functionality on the page will display different versions of the content What if the rel="canonical" returns a 404 Google will continue to index your content , However its is recommend that you specify existent URLs as canonicals.
    6. 6.  What if the rel="canonical" hasnt yet been indexed Like all public content on the web, Google will discover and crawl a designated canonical URL . As soon as it is indexed, the rel="canonical" hint will be considered. Can rel="canonical" be a redirect Yes, you can specify a URL that redirects as a canonical URL. Google will then process the redirect as usual and try to index it.
    7. 7.  What if I have contradictory rel="canonical" designations Google can follow canonical chains, but its is strongly recommended that you update links to point to a single canonical page to ensure optimal canonicalization results. Can this link tag be used to suggest a canonical URL on a completely different domain The answer is yes! Google now support a cross-domain rel="canonical" link element
