Online reputation monitoring has become an inseparable part of (successful) Marketing today. There are many costly tools (such as Radian6 and Scoutlabs), not to mention greedy agencies and consultants, which offer you this service, but here are 10 free online tools to help you begin monitoring your e-reputation.

Addictomatic

A very simple and intuitive tool that tells you what people are saying about you or your brand in a form of movable widgets. Addictomatic shows you results from Twitter, Friendfeed, Bing News, Google blog search, Digg, Delicious, Technorati, Twingly, etc. You do not even need to register on the site! In order to access your searches, you can just bookmark the URL of your search result and get back to it whenever you need.

Board Tracker

This one is less known than the previous. This tool specializes in monitoring forums. Boardtracker is currently following more than 66 million topics on more than 37,000 forums. English speaking forums are the most monitored.

Commentful

This is a service that monitors comments left on blogs, Digg, Flickr, etc. After sign-up, Commentful sends you a notification for every new comment.

Friendfeed Search

The less known relative to Twitter also has its own search engine. Friendfeed’s search engine is more interesting than Twitter’s. You can call this herecy, but not only does it retrieve text, but also generated content such as photos and videos posted by users.

Google Alerts

Google Alerts is an essential program for anyone who follows a brand or companies’ occurances and mentions on the Internet. It is simple and easy to use, and most of the time relevant. This tool has evolved a lot over the years, and you now have the option for transforming the alerts you set into RSS feeds – one very interesting option since dealing with mailboxes filled over capacity.

How Socialble

This is not a monitoring tool in the classic sense, it is rather a tool that takes notes on your visibility on social networks. You can have your Google Blog Posts score, Twitter score, Flickr score, Youtube, Myspace, etc, on the same page. This tool can be very useful to measure the impact of your actions across the social networks.

Icerocket

This one is above all a search engine that specializes in the indexing of blogs, using the “fresh links” concept to identify hot topics. It also offers a search module for Myspace, and this makes it the only tool of these that does so.

Keotag

As it is suggested, Keotag allows you to search content tags. Once you have picked a tag, Keotag lets you choose the sites you want to it search for you. Of course, the classics among the choices are: Google, Twitter, Technorati, Reddit, Digg and others. After search, all the filtered results are posted on the same page.
