Maximize the Link Juice of your Infographic with the use of the Canonical HTTP Header

Since June 2011 Google is supporting to set the rel canonical via the Canonical HTTP Header.

This is great for PDF files, but nobody seems to have mentioned images? Does it even work?

Link building with your infographic

A popular method nowadays, post penguin, is to use an infographic to attract links. But how do you do with those that only link directly to the image file?

Use this code in the .htaccess:

<FilesMatch "my-great-infographic.png">
Header set Link '<http://www.yourdomain.com/url-of-where-i-host-my-infographic/>; rel="canonical"'
</FilesMatch>

This is especially great if you provide an embed code with a smaller infographic that links to the image file for showing the full size.

Note: I am not sure if it works in Google. Maybe the image will not even be indexed?

Please comment below if you have any experience with this. Thanks.
