Nofollowed links are hyperlinks (anchor tag) with a rel=“nofollow” attribute. The nofollow attibute tells search engines to ignore that link.
It can be used anywhere in a html page. You cannot visually differentiate between followed and nofollowed links unless you inspect the html code.
Example:
<!-- This is nofollowed link -->
<a href="http://example.com/some-page.html" rel="nofollow"> Link Text </a>
<!-- This is followed link -->
<a href="http://example.com/some-page.html"> Link Text </a>
Note: If you want all links to be nofollowed in a webpage, then instead of adding rel=”nofollow” attribute to all links, just add a robots meta tag with value “nofollow” in the <head> section.
<head>
...
meta name="robots" content="nofollow" />
</head>
