How does no follow work?

Could you explain me how it work?

 

Basically Google ignores the links are doesnt count them as a backlink.

 

this would help you :

yes he is correct the spiders do not either count or follow the link.

 

These days yahoo and msn are also doing the same

 

agreed its all search enignes

 

nofollow is a way of not sharing your link-love :]

 

im also one of those people confused about "no follow" and following this issue. but IMHO(correct me if im wrong) search engine will either change, already changed or also confused how to treat no-follow.(maybe with secrecy)
Why?
most webmaster or SEO or maybe some of those who implement nofollow consider it was a failure. why again?
most links with nofollow links are coming from trusted websites(e.g. wikipedia, comments on blog from legitimate websites)
also captcha was widely implemented now and nofollow was less applicable for spammers.
i hope to hear more opinion from DP users.

it was from 2005 back when search engines was giving an importance to nofollow
also i dont trust that much to matt cutt. he was one of those who implement the rules and rules change overtime. IMHO(again) he was allowed to talked only for what he was only allowed.

 

no follow says to the search engine "dont follow this page", they still look at the pages it links to (you can track it by watching google download your site), for me i noticed google no longer followed the link.

nofollow also does not allow the link to pass on PR to that page is linking to, and you can use it to retain PR (prevent PR leakage).

Thats why google suggests for posts on blogs you have nofollow, so spamming is less attractive.

As for the other search engines im not sure, but ask.com ignores it fully and will crawl whatever it wants.

That's right. Not only less attractibe but even useless. Almost.

 

NO FOLLOW
- the Search Engine will not pass Link Juice (for Page Rank building purposes)
- the Search Engine will still index the link/URL

 

no follow help in link popularity only

 

nofollow is most useful for shaping PageRank.

 

If you add the rel attirbute rel="nofollow" to your urls bots won't follow it and pagerank wont leak.

 

All this is normal, don't worry about it

 

They are useless. If you are linking to no-follow sites Google will never count it as a backlink.
