what is nofollow and dofollow links?

thanks for this thread... it's really usefully information...

 

google crawl both nofollow and dofollow link but when at back link google not give much important to nofollow link , thats reason so keep try to submit your link in dofollow site, with your works r not going to worthless

 

A no follow links does not have anything to do in improving your SERP rank and the PR of your site because there is no link juice that may occur in those no follow links but somehow those links can come up with a traffic while do follow links are links that is been used to rank up your site well but to be sure you have its quality. Do follow links is said to be more important than the no follow links. There's a possibility too that you can gain PR with those do follow links

 

dofollow link is the link where google counts whwn it cralws the page but this is not in case of nofollow

 

Do Follow: It will greatly improve the number of links to your website which in turn will positively impact your rankings and traffic
No Follow: No Follow tags help us to prevent passing of page rank through a particular link. It s a red flag showed by us to search engines. If we mark one link as no follow then Search Engines wont crawl the link. But We can bring traffic through these type of no follow links

 

NO FOLLOW - is specially treated in google as no value. But for other search engine it may give you some positive result.

DO FOLLOW : is essential to all.

 

more value do do follow means that they give some value to no follow.
Is this true?

No follow are working for serp or pr anyway?
