While traditional media, like newspapers and television advertising, are largely overshadowed by the rise of social media marketing, there is still a place for traditional marketing. For example, with newspapers, readership over the years has shown a decline. However, readership with newspapers is still fiercely loyal to print-only media. 51% of newspaper readers only read the newspaper in its print form, making well-placed ads valuable.
Another example when the “nofollow" attribute can come handy are widget links. If you are using a third party's widget to enrich the experience of your site and engage users, check if it contains any links that you did not intend to place on your site along with the widget. Some widgets may add links to your site which are not your editorial choice and contain anchor text that you as a webmaster may not control. If removing such unwanted links from the widget is not possible, you can always disable them with “nofollow" attribute. If you create a widget for functionality or content that you provide, make sure to include the nofollow on links in the default code snippet.
