A canonical tag solves the problem that the site is not on the homepage

Some time ago because the bidding colleagues in order to facilitate viewing the conversion path, in each keyword has set a different URL, specifically directly behind the standard URL plus # and parameters, such as www.abc.com/#defgh, www.abc.com/#ijklmn, Because he set a lot of landing page is the homepage, so very prone to problems, low conversion rate does not say, may also cause a large number of duplicate pages, to Baidu site, www.abc.com not home, but www.abc.com/#defgh排在第九位, Immediately to the head of the page to add a canonical tag, two or three days after the site, home again back to the first

How do I add canonical tags? It's easy to add the following code between

<rel= "canonical"  href= "http://www.ytkah.com/"/> 

Used to think that canonical is just a label, did not encounter a similar situation, now know that it is very useful, but also in the other pages are also added
