We all know that 
There is another influential bot in this world that hates duplicate content. Its name is googlebot.
Googlebot crawls the web and determines which web sites will appear on the Google search engine.
Googlebot hates duplicate content as much as
The growing number of interfaces for SteemIt.com might create a problem for webmasters. Googlebot might decide all the different interfaces for SteemIt are "link farms."
I don't think this is a big issue for most SteemIt authors. People only make money on the first seven days of a post.
The canonical problem is a long term SEO issues.
For example, if you put a footer with a signature leading to your home page; Google would see the SteemIt clones producing tens of thousands of low quality links to your home page and penalize you for link spam.
I noticed that different steemit interfaces encode links differently. SteemIt.com proper adds the attribute rel="nofollow noopener" to all outbound links. The nofollow attribute tells googlebot that your link might be spam.
If you have thousands of links tagged this way; google will assume you are engaged in link spam and penalize your site. If you have a signature on your posts; you might want to use a url shortener to reduce the penalty.
The "noopener" attribute is used to protect against a strange cross-origin bug in javascript that hackers can use to phish for passwords. No-opener has the effect of telling the browser not to sent the http-referrer in the header.
Busy.org does not add these attributes. From an SEO standpoint it might be better to link your blog to your posts on busy.org than to link to the steemit.com version.
The rel="canonical" attribute is very important but is easy to misuse. You can use this tag to tell google which site is the original source of the data.
The growing number of steemit interfaces might create a world where google decides steemit is just one big link farm and it needs to penalize everybody who uses the platform. This would be bad.
I would love to hear thoughts from SEO experts on the best way to present links on SteemIt.com so that Google does not penalize the sites to which we link.
