What is dofollow?
Simply put, �dofollow� is a plain HTML link that indicates to users that text is hyperlinked. It also tells search-engine spiders to crawl your link.
If you�re familiar with basic HTML, �dofollow� links should be very familiar:
<a href="http://example.com">Your Anchor Text</a>
The term �dofollow� is used to describe a type of link in conversations like we�re having today. You will notice there isn�t an actual �dofollow� link relationship attribute, which is an HTML tag that tells the web browser the relationship of the linked document with the current document.
What is nofollow?
The link relationship attribute �nofollow� looks like this:
<a href="http://www.example.com" rel="nofollow">Your Anchor Text</a>
Still visible and clickable to users, what �nofollow� does is tell search-engine spiders to not follow your link, resulting in the following:
Spiders will not follow the link
Users may still click and follow the link
PageRank is not transferred
Anchor text is not transferred to your link profile
