WordStream continues to add to their suite of free search marketing tools with The Free Negative Keyword Tool to help boost efficiency and ROI in paid search marketing
BOSTON, MA – June 22, 2010 – WordStream, Inc., a provider of keyword research tools  for pay-per-click (PPC) and search engine optimization (SEO) efforts, today launched The Free Negative Keyword Tool , which is designed to quickly identify lists of highly-effective negative keywords for PPC advertisers.
With the launch of the Free Negative Keyword Tool, anyone who runs a paid search marketing campaign with Google AdWords, Bing AdCenter or Yahoo Sponsored Search now has the power to:
- Stop wasteful ad spend before it happens by proactively setting negative keywords and match types with the suggestions provided by WordStream’s keyword tool 
- Save time and increase productivity by identifying whole clusters of related negative keyword candidates rather than single instances of negative terms
- Perform negative keyword research  by eliminating any “positive terms” that are relevant to your website from your list of negatives and exporting your list of negatives in an AdWords-ready format
The Free Negative Keyword Tool from WordStream makes all this possible by identifying a list of high-traffic keyword niches which are related to your business, service or product as a first step. Next, you’re able to designate which of these keyword niches  are relevant to your business and which ones aren’t. The Free Negative Keyword Tool then saves any keyword terms you deem “negative,” and suggests additional, related terms that have a high likelihood of getting matched against the ad groups within your paid search accounts.
“The Free Negative Keyword Tool saves PPC advertisers the headache of going the long, tedious and expensive traditional route of waiting for your ad campaigns to mature and accrue query data, then sifting through search query reports to uncover negative keywords,” said Larry Kim, WordStream’s Founder and Vice President of Product Development. “So rather than wasting tons of time, money and energy, you can quickly and efficiently weed out irrelevant terms with our tool, thereby eliminating wasted spend before these terms ever cost you a single penny.”
