hi I'm guessing most of you know what nofollow/dofollow is. Well, here's a tutorial on how to make your blog dofollow. Making your blog dofollow allows you to be ranked in special search engines, thus increasing potential traffic.
The ONLY difference between a dofollow blog and nofollow blog is a nofollow blog uses the nofollow attribute in outbound links. This ONLY PREVENTS Google Pagerank being passed on to the outbound link. It does still count as a backlink, and if anyone wants to claim others just simply build a bunch of nofollow blog comment links and wait till Google updates your Google Webmasters Central links and guess what... they'll appear! The entire concept behind the nofollow attribute was to discourage text link sales.
dofollow/nofollow is only important if you really care about pagerank. anyway, whether you use nofollow or dofollow on your blog pages, focus to link to pages related to your blog content.
OK, it may result in some traffic. The best thing is that these visitors will post some comments so they will create new content for your weblog. This is in my opinion the main value of dofollow weblogs. Edit: There is something wrong with your weblog. I tried to add comment to your post but when I click the "post comment" link nothing happens.
Differences? Both blogs types (nofollow,dofollow) are spammed. Thanks to the existence of WordPress spammers have something to do all the time . So there is only a little difference at all. You'll get spammers on any blog and even dofollow blogs' webmasters don't recognise some spam properly (because many spammers do spam manually, so captcha means nothing). Do search engines prefer dofollow or nofollow? No. Do spammers prefer dofollow or nofollow? No.
