What I have noticed, along with quite a few other bloggers, is that Google Alerts misses a lot of local results. Also, it returns quite a few older results that are irrelevant due to being outdated. In a time when we get flooded with information, this can be really annoying. Another drawback with Google Alerts is that you have to add keywords one by one which makes it hard to manage when you add a lot of keywords.
There are a few options out there that I think do a better job, such as SocialMention for social media, Google Blogsearch for blogs etc. where you can set up RSS-feeds and monitor your search results. This is better than Google Alerts in the sense that it gives better results, but it is even harder to manage multiple search words when doing it in different channels.
For this reason we have developed Rynge Media Monitor (currently in beta). I would like to invite the readers of this blog to try it out.
