Introduction of Do Follow and No Follow Link
To the average website user, do-follow and no-follow links look exactly the same. However, no-follow
links include a small piece of code, called an attribute, that lets search engine bots know not to follow the
link. According to Google, no-follow links don't pass any PageRank to the website being linked.
A no follow link is a link that does not count as a point in the page’s favor, does not boost PageRank, and doesn’t help a page’s placement in the SERPs. No follow links get no love. Theirs is a sad and lonely life.
A no follow link is created with the no-follow link HTML tag, which looks like this:
<a href=”http://www.website.com/” rel=”nofollow”>Link Text</a>
The no-follow tag is basically a notice sign for search engines saying “don’t count this.”
Isn’t that just mean and terrible? Why would anyone do such a thing? There’s a reason for the no-follow attribute, and boy is it a good one!
Do Follow
The term “dofollow link” is used to describe a link that passes the authority as opposed to one that doesn’t.
Technically, it is not a correct name because there is no such thing as rel=”dofollow” attribute. Some SEOs are quite strict about this.
No Follow
No-follow is a value that can be assigned to the rel attribute of an HTML a element to instruct some search engines that the hyperlink should not influence the ranking of the link's target in the search engine's index. It is intended to reduce the effectiveness of certain types of internet advertising because their search algorithm depends heavily on the number of links to a website when determining which websites should be listed in what order in their search results for any given term.
A no-follow link is a link that contains a rel=”nofollow” attribute in its HTML code. This attribute tells search engines not to pass authority from the linking page to the destination page. As such, no-follow links have very little value from the SEO point of view.
The no-follow attribute was introduced in 2005 by Google, Yahoo and MSN in order to fight the comment spam by giving webmasters the option to devalue certain links.
