Hi im just wondering how i will know if a link is follow or nofollow link? will i be able to see it in the HTML tag?
If you're using Firefox, you can download this extension: http://www.quirk.biz/searchstatus/ It will highlight the link that is no follow with red color. So the one that is not been highlight is a dofollow one.
You can either view the page source or use the firefox extension dynashox suggested. I use that extension. Much easier and quicker than viewing the page source everytime. If you use the view page source option you need to look for rel="nofollow" or rel="dofollow". nofollow will tell the search engine bots to disregard the links it might find on page so that the site doesn't provide any linkjuice
Links with nofollow attribute does not allow pass PR to your particular link. Dofollow no need to write on the page. Still if you want to find nofollow links on website, install seoquake it will shows details whether the link is nofollow or not.
A nofollow link will have a rel='nofollow' attribute in the tag Example <a href="http://www.google.com" [COLOR="Red"][B]rel="nofollow"[/B][/COLOR]>This is a link text</a> Code (markup):
Here is an article on my blog that explains how to check no follow links in either IE or Firefox. I have been using the script for a while and it works great.
