Buffer lets you schedule tweets according to a schedule that you set, allowing your tweets to appear at an optimal time. Tweets at night generally get much less attention than tweets in the morning. With Buffer, you can schedule tweets at night to appear the next morning. This is a snap with their browser extension which makes adding and scheduling tweets easy. Buffer will also schedule posts on Facebook and LinkedIn. It’s really easy to use.
If you’re not sure when your optimal tweeting hours are, just ask Tweriod. It’ll analyze your Twitter account, then tell you what the best times are. Set up your Buffer schedule using that.
Buffer and Tweriod are free, with low-cost pay versions with added functionality. I’m using Buffer continually now. If I post something at night on this blog, then with a couple of clicks, it’ll be on Twitter and Facebook in the next optimal time slot. Support for Google+ is coming.
