Key Difference: A DoFollow link passes the SEO strength or the Page Rank of the page to the website to which it is linked. On the other hand, a NoFollow link is the link that is generally ignored by the search crawlers. Both are expressed as html attribute values.

DoFollow and NoFollow links are the incoming links from different web sites to a webpage. These links are associated with the search engine optimization, as the account rankings of a website are also affected by these links. Both these links are properly considered by the webmasters.

Search engines like Google, crawl a website and determine that these links point to some other websites. If the link is a DoFollow link, the search engine follows that link and the PageRank is transferred for that particular link. On the other hand, if the link is a NoFollow link, then search engine bots are not allowed to follow any of the links. However, few search engines may crawl the linked website, but still no PageRank is transferred for that link. It was designed so that the web site owners could stop the indexing of links by the search engines. Therefore, no authority or the “link juice” is transferred to the linked site from the source site.
