Twitter has become a major part of social median and there are several tools available that can make your post visible to different audiences. I became aware when I signed up with a free service that gave me a daily report of where my tweets were being viewed and what time. It was clear that I was not tweeting when I was getting the most views.
So with that in mind I used the free service to schedule my tweets. I could place the tweet to go out when I seem to get most interaction, and I was sleeping. They may have to wait for my replies but the tweets were fresh for their eyes. As it turned out many of my views were coming from the UK.
Things do change and my topics change as well. So now I keep track and schedule my posts on social media at time when I hope they will have the greatest impact. I find that checking it weekly and making the adjustments is best for me.
Facebook also has some scheduling options with some pages. Since you are going to take the time to share, make it worth your time.
