Do links you post in Twitter help your search rankings in Google and Yahoo?

[Brett]

I am wondering if it is worth it to create some back links to a website on Twitter with regards ONLY to the search engines.
Not talking about tiny url - legit http://www.xyz.com links.

I think most of the links posted in twitter are Tiny URL, and that does not help.

Twitter adds a “nofollow” attribute to links submitted by its users. The “nofollow” attribute advises Google, and a few other search engines, to ignore the link. Some of these follow the links but exclude them from their ranking calculations (Yahoo!, Google); some ignore the links completely (MSN). The only known search engine that doesn’t comply with Google’s “nofollow” at all is Ask.com.

Do tinyURL Shortened URLs Have SEO Value?

The short answer is yes. TinyURLs are dynamically created URLs that redirect users to the real URL via 301 (permanent redirect). Search engines do not index TinyURLs, but index and pass PageRank to the actual URLs instead. The problem with Twitter, as we already discussed, is the “nofollow” attribute added to all submitted links.
