Thanks everyone.
I subscribe to an online marketing newsletter and just received this, "Skittles increased its own traffic by 1332% in one day after a campaign that sent Skittles.com directly to a Tweet-stream..." It also said that Twitter grew 33% last month, according to Compete data.
Another piece of advice: follow your competition to see what they are Tweeting about. Robert, I'm following several real estate agents and they do just what you are suggesting.
The best way to learn is to go there several times a day and see what others are doing. I have a client who said she didn't have the time and didn't understand it; well, she emailed me today saying, "I'm addicted."
It's a lot of fun!
Thanks again. It was a fun article to write.
You can "follow" me, and I'll follow you too; we can learn from one another.
Have a wonderful day!
