What is the difference between Do follow links and No follow links?

when google crawl any website he crawl only dofollow links in your site... and skip nofollow links....and nofollow links are to told google bots not to crawl this link and continue crawling....

Nofollow links will not increase your page rank and Dofollow links helps you in increasing your page rank...

With DoFollow link, you will gain the backlink from the website. This help to increase your page rank.

Building back-links to your site is an important strategy for any internet marketer. However, not all links are equally valuable, and some may even be worthless. Many blogs, forums and article directories add an attribute called nofollow to their outbound links to discourage people from spamming the site with irrelevant links.

A normal dofollow link on a web site will look something like this:

<a href="http://www.link.com">Link</a>

To make an individual link nofollow, the value is added to the rel attribute in the html link tag:
<a href="http://www.link.com" rel="nofollow">Link</a>

The nofollow attribute was developed in 2005 by Google to help combat link spam in the comment section of blogs. It was designed so that webmasters could attach it to all unwanted links that are unrelated to their site, so that Google could improve the quality of their search engine results.

Great stuff brainpulse. You make it so easy to understand about do-follow and no-follow links. I would like to thank you behalf all info seekers on this.

Nofollow are for not crawling a link by search engine. Dofollow allow search engine to crawl links. Nofollow tag we can use if we are using a link for reference not for crawl. Both are good for human traffic.
