Has anyone seen improvement or good improvement on sites/kws that involved a tweet that was retweeted. So basically getting many retweets and that moving your website up? So far I gather you should include your kw you want to rank with the url in the tweet and that needs to be retweeted for the boost. I knwo there are services out there where they dripfeed tweets over a period. Would like to hear your views on this, as I have started my social profiles on g+, twitter and FB. Site stuck on 2nd page for many kws and looking for other ways to boost rankings, as I have done the PBN, diverse links and so on. Love to hear from you.
