I mailed a few weeks ago comment to "nofollow" blog and now it appears in my webmaster tools. Is this link any benefit to me? link juice? SERP? nothing at all?
Compared to dofollow, nofollow is less beneficial and there are very less chances to get link juice from nofollow.
nofollow is introduced by Google in 2004 i think,, if you place your nofollow link in PR9 website you will be NO BENEFIT of this, if you use dofollow, you will get backlink from it
there's no benefit of a nofollow link except that it may give you a visitor when someone clicks it and a blend of nofollow and dofollow links make link building look natural.
back links are backlinks all back-links giving serp results even twiiter no follow giving serp results.
This is being paranoia about nofollow, this is not correct, google said if you add nofollow, then they will not crawl from the original linking website to the linked website, but google know for sure that that link exists, so how do you know whether it gets counted or not, you might not be getting some of the benefits of a full fledged dofollow link, but remember "a backlink is a backlink"
As COBSolutions said "A backlink is a backlink" I would not worry about nofollow or dofollow. Any backlink will help in SERP, and that is what really matters.
agree, that backlink is a backlink, and it doesn't matter dofollow or nofollow... search engines changes rules quite often, so may be...
Why? Could you please explain? I said that on my point of view as I don't care about PR. To me SERP is all
nofollow is used specifically to PREVENT helping with SERPS. "A site's ranking in Google search results is partly based on analysis of those sites that link to it. In order to prevent paid links from influencing search results and negatively impacting users, we urge webmasters use nofollow on such links." http://www.google.com/support/webmasters/bin/answer.py?hl=en&answer=96569
I think COBSolutions is right here. I did read an experiment that showed that building only nofollow links will still get your site crawled and indexed (experiment was on a new domain with no links). At the end of the day, I'll take a link given freely regardless of nofollow/dofollow.
Google can index new sites without any backlinks with new domain registration (years ago, you did need backlinks for them to index a site). If your trying to increase your rankings, you should only be worried about links that will help you with your rankings. The only value to a nofollow link would be direct traffic. Getting a new site indexed is easy - ranking for any competitive keyword is what separates the noobs from the rest. The OP question was about link juice or helping with SERPS - the correct answer is that a nofollow gives no benefit.
No PR or anchor text value is passed through nofollow. But they may help in other search engines. It's better to have a blend of both.
You se, though Google doesn't count nofollow links in PR and juice terms, the algorithm does know they're there, and they are counted in your total link count (i mean your outgoing link profile here). That said, it may (and usually does) crawl the nofollowed links to index new pages. From the linking site's perspective - nofollow links still influence your overall linking profile (negatively). From the site linked to perspective - nofollow links to you carry little value, unless they generate significant traffic.
