How do you rate links from sites like Twitter and Facebook?

Mani from Delhi asks:

"Links from relevant and important sites have always been a great way to get traffic & acceptance for a website. How do you rate links from new platforms like Twitter, FB to a website?"

Regardless of what Matt says (but mentions in a round about way), everyone forgets about robots.txt files on these sites. Google cannot get to Facebook users pages because they have to be logged in. And certain types of pages are prevented being indexed by its robots.txt file. Same goes for Twitter, which puts NOFOLLOW tag into public pages, but where search results pages might "look" like they do not have NOFOLLOW tags on them, the Twitter robots.txt file prevents Google crawling them anyway.

Thanks for the videos. However, if feel this really didn't address the question directly enough to be helpful in this instance... I understand there is a certain amount of secrecy behind the formula, but simply saying that nofollow links affect the way the spiders work isn't exactly a revelation. Any way you can clarify a bit?

I Like the haircut Matt!!! looks Great! and it does matter what domain extension your links come from. edu links do pass more "juice" its documented in Google and many SEO websites .... just a heads up...

The crucial point is whether social profile pages are crawlable by Google.

I agree...i have seen a number of websites gain rank over linking back to the "Trust Networks" Such as LinkedIn Twitter and Facebook. so im curious...as to what REALLY is happening with the new Google algorithms. More in-depth information is needed.
