Whenever we
talk about search engine optimization, some of the common words are noindex,
doindex, nofollow, dofollow, meta robots and so on. All the words hold equal
importance in the book of SEO. In this post I will be explaining about Nofollow
and Dofollow. Specially for newbies who are new to SEO or people who are still
not clear about Nofollow or dofollow, this post will be useful.
Did You Know?
Nofollow is
an HTML attribute value used to instruct search engines bots that a hyperlink
should not influence the link target’s ranking in the search engine’s index. It
is intended to reduce the effectiveness of certain types of search engine spam,
thereby improving the quality of search engine results and preventing
spamdexing from occurring in the first place. This is a concept introduced by
Matt Cutts and Jason Shellen in the year 2005.
What Is The Difference between NoFollow & Dofollow
Nofollow
links attributes do not allow search engine bots to follow link.That means if
the website owner is linking back to you with nofollow attributes, it does not
pass on link juice. Only Humans will be able to follow the links. Though some
time back Google made it clear that they don’t consider nofollow link
attributes but weightage of such links are really less. Even though, it’s a
good practice to use Nofollow link attribute to those link, where you don’t
want to pass link-juice.
Example of
Nofollow Link:
<a
href=”http://www.google.com/” rel=”nofollow”>Google</a>
Dofollow
links allow google (all search engines) to follow them and reach our website.
Giving us link juice and a backlink. If a webmaster is linking back to you with
this link both Search Engine and Humans will be able to follow you. The best
way to give someone dofollow love is allowing keyword in the anchor text. This
means when you are linking to any website or page, use the targeted keyword as
anchor text.
Example of
Dofollow Link:
<a
href=”http://www.google.com/”>Google</a>
Note: By
default all the hyperlinks are dofollow. So, you don’t need to do anything to
make a link do-follow.
Important
Notice:-
Recently
Google have said that they will still count the nofollow link as an outgoing
link in terms of the distribution of page rank from your page. Though again it
also depends on where that nofollow link is places. Placing a nofollow link at
the bottom of the page has least impact, and when placed at the top of the
page, it carries some impact.
Types Of No-Follow
Robots Meta
Tag : <meta name=”robots” content=”nofollow” />
This tells
bots/crawlers/spiders not to follow links on the full page.
Link
Attribute : <a href=”http://www.google.com” rel=”nofollow”>
This tells
search engines not to count the link in terms of ranking pages.
Quick Tip:
Try to keep noindex attribute for pages like contact and nofollow attribute for
affiliate links on your blog posts. If you are linking to any spam website for
any reason, use the nofollow link attribute.
