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.
“Sharability” – Not every single piece of content on your site will be linked to and shared hundreds of times. But in the same way you want to be careful of not rolling out large quantities of pages that have thin content, you want to consider who would be likely to share and link to new pages you’re creating on your site before you roll them out. Having large quantities of pages that aren’t likely to be shared or linked to doesn’t position those pages to rank well in search results, and doesn’t help to create a good picture of your site as a whole for search engines, either.
