I have done some research on tweeting effect. Google and Bing are consider social media in their algorithm. I want to conform about social media effect. My Research: I wrote an article title "sample key phrase #1" & i kept it as it is (not sent anywhere) and I search on google and bing "Key Phrase #1" but it didn't seen anywhere. So I have write another article on the same subject (which I written before) called title "sample key phrase #2" and tweet it on main "key phrase", so as a result my article after 1 day...on Google #25 & Bing #17. I did next research like using my another account I retweet again on tweeter. I surprise by getting Google Ranking after 1 day: Google #7, Bing #3: Suggestion: For all seo's do all article tweet on tweeter, It makes sense and If you need any help A-S-K M.E
It is unbelievable that SMO activities will helps in rankings that much which you have mentioned. May be but not that much.
Yeah, it's effective. I'm following this since a year. The more retweets you get, more value added to it.
