In the past, I would have said ‘no’. Today Twitter has become so noisy, as have most social media sites.
This makes it harder for your audience to see your message. Social media has become one of the best ways to inform your audience.
You can repeat a tweet, but how often? Its going to depend on the size of your audience.
If you only have 1000 followers repeating the same tweet 30 or 40 times in a week is going to piss some of them off.
However, if you have 6 or 7 million followers, it can take 30 or 40 times in a week for all of your followers to see a certain tweet.
I would vary the tweet or tweets that you want to repeat as much as possible without losing the message.
Change the wording up a bit, and maybe use different hashtags, so you can reach more people.
You can still use the same link if you have one in the tweet, but change the tweet up somewhat.
If you have an image change that also, and don’t forget to change the time and the day of the tweet, so you can connect more globally.
This will also help to make it seem less automated.
Happy Tweeting
