Start using Canonical links today!
This prevents & helps eliminate duplicate content issues when search engines index your website. You can also use it to specify AMP pages on your website, if you do have AMP pages.
*** ( please remove the space between < link I had to add it to make the code visible in the post )
linking to the same page ( to prevent duplicate content
Add the following ( using your own domain name and routes / page names ) to your head section of each of your webpages
< link rel="canonical" href="http://yourdomainname.co.za/samepage.html" />
linking to your AMP page ( if you have AMP pages )
< link rel="amphtml" href="http://yourdomainname.co.za/amppage.html" />
So, if I have an existing website and I’m copying content from there onto steemit, where would I include this code in smeetit post?
