Why add the nofollow attribute
Most search engines find new web pages by crawling the published sites' links.
"Most of our Search index is built through the work of software known as crawlers. These automatically visit publicly accessible webpages and follow links on those pages, much like you would if you were browsing content on the web. They go from page to page and store information about what they find on these pages and other publicly-accessible content in Google's Search index."
As the links are essential for the search engines, any links that intend to manipulate the sites' ranking in the search results can be considered a violation of search engine guidelines. Here are some examples.
The nofollow attribute is recommended to use when you don't want to associate your site with an external page.
