WordStream announced a free negative keyword tool.

A report from Search Engine Journal says:

In PPC marketing, the ability to narrow down your keywords and have selective strings can mean the difference between wasteful and efficient spending. If you’re used to using a traditional keyword suggestion tool, this will be no different- it gives you suggestions on negative keywords that you should add, that could ultimately affect your campaign.

This negative keyword tool will:

* Export your negative keywords list in Google AdWords format for easy handling
* Identify clusters of negative keywords- this is less time consuming then doing them individually
* Be proactive with negative keywords to eliminate excessive and unnecessary spending
