Besides link-building, the traffic is also a rank factor. I'm going to publish new website soon and I thought I should give him as much traffic as I can in the first day, to boost its ranking. And one thing came to my mind. Online services like browsershot or HostTracker visit your page multiple times and some of them from multiple places. Is there any sense in this kind of stuff? Could it be penalized? Or how can I expand the idea if its worth at all. And if my question sucks the big one, would you share your care methods when releasing a new website?
You're talking about mimicking traffic - that would not be a sustainable effect, even if it does get seen as real traffic. I doubt there's anything artificial you can do that will give a significant boost to rankings this way.
As a whole? Twitter content is not exactly "news". However, a lot of real news - important news - first shows up on Twitter. In addition, links on Twitter can generate a lot of traffic and Google partners with Twitter and gets all their data in a real time feed called "the firehose."
