At the beginning of the week I've not done that much.
I followed/unfollowed not that many people. Posted and retweeted only ~ 2 posts/day.
Did not schedule posts and made no lists, vids...
status beginning of the week: 2458 / 8248 (Follow/Follower)
end of the week: 3210 / 8773
Twitter profile: https://twitter.com/wemakesomemoney
So I got ~ 500 new followers this week.
I followed and unfollowed people. Used unfollowers.com and other free twitter online services.
With more action and a better profile it could be much more, I think.
Wish You Success!
