Marketing on Twitter is not just about sending out a tweet to your followers hoping that they would get to read it.  There are tools online that help you maximize your Twitter campaign by helping you work smarter, not harder.

If you take your Twitter marketing campaigns seriously, then take a look at these tools!

Know the best times to tweet with Tweriod.

Some business owners and Twitter marketers do not put much thought as to when they should go on Twitter.  They just assign an arbitrary time such as 12 noon or 12 midnight.  Others get on Twitter when they are not too busy.

But have you ever thought about who would get to read your tweets if you send them out at a time when most of your customers are fast asleep?

If you have ever wondered whether you are tweeting at the best time or not, then you should check out Tweriod.

Tweriod basically tells you the best times to tweet based on your own tweeting activity and that of your followers. It then gives you the best times to tweet every day.

What’s great with Tweriod is that you have the option to sign in with your Twitter account.

After logging in, Tweriod would begin preparing your report and would send you a direct message when it’s done.  How long do you have to wait for it?  It depends on how many followers you have!

You could also get more information by availing of their premium reports starting at only US$2.50!
