Detecting NoFollow Links
Written by Joe on March 13, 2009 – 1:38 pm -
As you may already know, placing a re=”nofollow” attribute on a link will tell search engines, like Google, to not follow the link – or give credit as a vote when it comes to search rankings. This is a pretty popular thing to do to control the links in user generated content like forums and blogs – since you are who you link to, so to speak. This also helps to discourage spammers from targetting your web pages, though not always.
At any rate, you may have reasons to quickly and easily find the nofollowed links on a page, to see if your tags are done right or to easily detect where and what is getting the nofollow tag on a page. We won’t go into all of the uses, though you can use your imagination. At any rate:
Internet Explorer Detection
Paste this code into your url bar on the page you’re wanting to check, or do what I do and make it a link favorite so you can check the page with one click. I link this better than the FireFox method because maybe I don’t want every nofollow link highlighted on every page I view…
javascript: var anchors;anchors = document.getElementsByTagName("a");var anchorIndex;for(anchorIndex = 0;anchorIndex < anchors.length;anchorIndex++) { if(anchors[anchorIndex].getAttribute("rel") && anchors[anchorIndex].getAttribute("rel")=="nofollow") anchors[anchorIndex].style.backgroundColor="red";} void(0);
Firefox Nofollow Detection
You could install the SeoQuake extension and turn the nofollow highlight on in the options, or search for userContent.css and add this anywhere inside of it… (Windows XP users can find it at C:\Documents and Settings\[User Name]\Application Data\Mozilla\Firefox\Profiles\yad55ash.default(varies)\chrome\userContent.css)
a[rel~="nofollow"] { border: thin dashed firebrick! important; background-color: rgb(255, 200, 200)! important; }
Google Chrome Nofollow Detection
Drag this into your bookmarks…
Safari Nofollow Detection
This is pretty much the same as Internet Explorer (IE6 or IE7), again I’d suggest making a bookmark of any page then editing the url location with this javascript…
javascript:var%20a=document.getElementsByTagName('a');for(var%20z=0;z%3Ca.length;%20z++){if(a[z].rel==’nofollow’){a[z].style.border=’1px%20solid%20%23F00';}}

I think google should give higher rankings to blogs that use dofollow. I dont know if they do but they should give some sort of bonus for being dofollow and not nofollow.

Well, im using firefox’s no follow detection add-on. It’s so easy to detect it where the link is highlighted with red which is considered this a noFollow link.
