Take the weekends off.
You tweet hard for the money, no doubt hoping that your followers will recognise your genius and retweet you. Well genuises, you can take weekends off as it seems that retweeters have better things to do on Saturday and Sunday. At least this is what this chart from HubSpot reveals.
Ask and thou shall retweet.
Humans are strange but utterly malleable. As this HubSpot graph to the left shows, ask followers to retweet your content and they will. Even the wording of how you ask effects the influence you wield. Who knew? You do. Exploit it.
Thanks again for the links Brett and Hootville. Hubspot is a great website and well worth a good read.
