What are the best tools for social media monitoring?

1. Hootsuite.

2. Google /Twitter /Pin/ Y Analyitcs  

3.Facebook Insights.

4. Klout score.

5.Keyhole.

6. Instagram .... 

I concur with  Yessaad Mohamed El Amine Amine  and in addition to that i think it depends with which media site one wants to monitor and to some extent some tools are best suited for certain sites and some for others.

• Social Mention
• Buzzsumo
• Mention
• HowSociable
• Addict-o-matic
• Google Alerts

And so many more....

Take a look and find what suits you.

In summary :

1. Facebook insights
2. Socialbakers
3. Hootsuite
