Does a link from twitter help in rankings?

No not at all

 

No the links from twitter are nofollow no use for rankings.

 

We have found that twitter link is nofollow. So link from twitter can not help in ranking. But it will give traffic for your website

 

This is totally true.
Google seems to be taking into account (or planning to do so) the "likes" and "twits" a page has. It will understand it as a measure of the quality of a page, what makes perfect sense.

 

same counts for digg?

 

traffic, you can get good traffic from twitter.

 

traffic from twitter is fine, less help for seo

 

It could be but not have a big effect

 

I think If you have a huge amount of followers, it can boost your traffic but not SERP ranking

 

Google bots can access Twitter's backend and crawl from there. Which means it is possible to index websites just using a Twitter account. This is true until Google changes its algo.

not sure if it helps any ranking system ... but it does provide traffic to my sites

 

you can get only traffic with that. No more other benefits.

 

Agreed.

Even though all twittter links are nofollow, any link is good - but it is an incredibly small value unless you have a 'real' twitter account.

A nice side benefit is that a lot of sites include tweets in their websites. If your link is not shortened, that site will provide better link value to you - but still not great.

 

I have noticed that twitter does get indexed.

 

well it is better if you have a link on twitter or on other networking sites.... it counts bt not directly....

 

Yeah its more brand awareness. Links dont pass weight.
