Tweetbeep is an excellent service that sends you an alert by email every time a particular keyword or phrase of your choice is mentioned on twitter. This is an excellent tool for online reputation management and works exactly like Google Alerts.
With the help of Tweetbeep it would be easier for you to keep track of conversations that mentions you, your products, your business or anything that interests you. It comes with an hourly update so that you won’t miss a thing. Another great thing about Tweetbeep is it lets you keep track of who’s tweeting your website or blog, even if they use a shortened URL service like (like bit.ly or tinyurl.com). However please note that the domain alert feature doesn’t come with the free account.
This service has been around for quite a while, if you still haven’t used them – Try it out today!
