Tracking and monitoring how well and far your content spreads on Twitter is valuable information for most users, but particularly brands and marketers. Putting an actual number on reach for any URL, username, keyword or phrase is both useful and actionable.

TweetReach gives you detailed reach analysis for any search term on how tweets about that term have spread on Twitter, and returns the data quickly and efficiently as a snapshot.

Premium options are also available, including a one-time report which tracks up to 1500 tweets for $20, and TweetReach Pro, which allows you to monitor stats in real time (ranges from $84 to an eye-opening $899/month).
