Dear Friends , Does anyone can Explain what is Do Follow and Do not Follow Bolgs/website ? and what is Advantage of Do Follow ? thanks
"No-Follow" is by default added on all links on Comment Sections of a Wordpress powered blog, which tells the search engines that "this link and its contents dont have direct connections with this blog". And though Search engines crawl through a No-Follow link, they don't give any value or page rank flow to that site. It was implemented primarily to prevent spammy kind of comments on blogs just to gain some Search Engine ranking/Google PR. But as its evident you can't stop spam that way. So i would say for a genuine wordpress blog adding this plugin "http://www.semiologic.com/software/dofollow/" will remove no-follow from all links and will encourage visitors to comment more. But you have to mention that in your blog that 'You Do Follow all Comments/links'. Hope that helps
nofollow is an attribute used for external link (sometimes for internal links as well). if a link is nofollow, then google will not follow the link to the external site. other search engines still follow nofollow links however. if google doesn't follow the link, then no link juice is being passed to the external site. sites use nofollow both to limit external links and to cut down abuse/spam
If there is nofollow tag on the <A HREF=.....> command, and If you placed your link inside it, your link will not follow by google, Google will not take the current page's PR(Where the link is placed) as well as it won't care anything, however, it will take it as a backlink to your site. On the otherhand, If it is DOFOLLOW, google gather all the info about the page where the link is placed(PR, niche, this and that and alll...), So, that is useful in terms of SEO rather than nofollow....
Dofollow links will help increasing your page rank, but still no dofollow links will help in indexing.
