You probably use Google Alerts to notify you whenever a keyword or keyterm is mentioned on any of the sites it indexes and monitors (if not, you should). Here’s an alternative. Scratch that. Call it a supplemental resource.
Talkwalker Alerts will let you monitor media and social media (news, blogs, discussions, and Twitter) for any mention of a keyword/term you enter. Like your brand, for instance. It can email those notices to you weekly, daily, or as they happen.
Oh, it’s free.
