Hi guys,

What is your experience of links from Twitter/Facebook and other authority nofollow social sites?

I've read confirmation that your social profile is included in rankings from a Google/Bing perspective.... However exactly how much of a ranking factor this provides is the question I am asking....

I can share my own experiences:
1)   They are good for getting pages indexed.
2)   They seem to have some ability to improve ranking but only if a page gets kind of viral.  Here is what I mean:

I have used a number of different services to pound pages with links from Facebook and Twitter.  Never once have I seen a page improve in ranking that I could determine to be because I hit it hard with those kinds of links.
However, I have had certain pages on my better sites that went semi-viral completely naturally.  When that happened, those pages moved higher in the search results.  In fact, I was shocked to see one page rocket to position one in Google.

The only thing I could attribute that ranking increase to was genuine sharing happening on social media sites.  Why this occurred and how I could repeat those results still eludes me.

I have read other stories that I trust where people have had similar ranking boosts that they were unable to attribute to anything other than genuine social media popularity.

So my opinion –They are useful for indexation because Google and Bing both follow them.  If you can build something that goes semi-viral in social media from genuine accounts, then it probably will give you an impressive boost in rankings.

Good for the social traffic, but hard to gauge an effect on SEO.

Well these sites which you mentioned(Facebook and Twitter) definitely give you traffic but there is no benefit from these sites related to getting the back links because these sites are no-follow. But the fact is that you can do much much more traffic from these sites instead doing other activities instantly.
