This post is just a quick overview of some free tools out there to help measure some of your social media efforts.
1) Facebook Insights will provide some good in-depth information for a fan page. You can download these date into Excel or you can snapshot the graphs they offer. (keep in mind though that FB data aren’t always that accurate but can provide a good overview). You will need to do a bit of analysis with these data but they can help you determine what types of content your community likes and interacts with. You can access the insights for all of your Facebook pages here: http://www.facebook.com/insights/
2) Twitter Counter will show the growth of followers for your Twitter account the past week, month, 3 months and 6 months. This site will also graph the number of tweets per day.
3) Tweetreach will show the reach of a twitter ID, a hashtag or a phrase. The free version only offers data for the most recent 50 tweets. This is important to remember so that you run a report right after a campaign or after a certain event.
4) Wildfire has a pretty cool social monitoring tool that allows you to track your Facebook page or Twitter against competitor accounts. You can find it here: http://monitor.wildfireapp.com/
5) Socialmention.com is a great social media search engine that will track mentions of your company, brand or a specific phrase and also provides feedback on overall sentiment of those mentions.
6) I also recommend bit.ly as a URL shortner. It is good for tracking link clicks.
These are just a few of the tools that can be used for measuring some of your social media and online activities. There are, of course, other paid subscription tools out there that will offer you a much deeper analysis of your social media efforts.
