Nofollow links are links that are given an attribute value in the HTML code that tells the search engines no to count these kinds of links towards ranking a given site. The code looks like the following:
<a rel=”nofollow” href=”http://www.seoblogtips.co.uk>SEO Blog Tips</a>
These kinds of links were invented to try and fight blog spam comments. As webmasters and SEOs used to spam the hell out of blogs just to get links back to their site Google decided to make the nofollow to try and tackle this obstacle.
Each search engines has different rules for nofollow, some count the links, others only just follow the links to get to new pages/sites. Below is what the main search engines do:
- Google – follows nofollow links but simply does not pass on anchor text or page rank.
- Yahoo – follows nofollow links but simply does not pass on anchor text or page rank.
- Bing- follows nofollow links but simply does not pass on anchor text or page rank.
- Ask.com – does not use nofollow links at all.
How to Spot Dofollow/Nofollow Links?
There is a Firefox add-on that tells you which links use the attribute. The add-on works like the following:
- Nofollow= Links are highlighted in red
- Dofollow= Links are highlighted in blue
When you have the add-on installed, you can enable it by right clicking and press “NoDofollow.” Have a look above to see the Nofollow highlighted in red and the Dofollow highlighted in blue.
Should I use Nofollow Links
You make think, just because the search engine does not count nofollow towards ranking then there is no point going these kinds of links, but there are three main reasons why you may/must:
The main reason to not worry about nofollow is if you are getting links for advertising. If you have links to websites that are just for click-throughs, then nofollow does not matter.
The other reason is, as Google looks for natural link building, not everyone that links to your site will use dofollow links and if you go out there and get tons of dofollow links then this does not look very natural does it? You need to mix the link building up and get some nofollows also.
The last reason is, just that the links do not pass page rank or anchor text, that does not mean the backlinks can not be used to get pages indexed by the search engines.
