Its easy to forget that unlike Facebook which only shows users a limited amount of content, Twitter shows a user all the tweets for the people they follow. That means that if a user follows hundreds or thousands of accounts your important tweet could get lost in this deluge of information.
Don’t tweet the important stuff just the once.
For important tweets its good practice to tweet the information three times over a 24 hour period (say morning, afternoon and evening?) and then three remaining times over the next 7 days.
You may want to vary the text used just to keep things fresh. We’ll discuss websites that can do this for you in advance tomorrow.
