Twitter has made a few changes recently that have changed our ability to easily track retweets. Previously when someone wanted to retweet something I had written they would simply place the following in front of the tweet: RT @sammillersells and then copied and pasted the message. When they did the retweet manually inserting the RT @sammillersells the retweet would show up on my home page below the home button under @sammillersells. I have found that since Twitter added the new "Retweet" feature at the bottom of each post these retweets are no longer showing up on my home page under @sammillersells.
You can use the Twitter search feature to find retweets but a more automated system is to simply use a Google Alerts notification. At first I was just using Google Alerts for my websites, community names, my personal name, business name and my team. Then I got the idea that I could setup a Google Alert for @sammillersells and it would automatically send me an e-mail when someone used @sammillersells online. If you haven't used Google Alerts I think it is worthy of testing out. I know agents who setup Google Alerts for every home address of all their listings so if anyone tries to scam a rental advertisement on Craigslist they know about it right away.
