Keyword research platform WordStream has released a free negative keyword tool. If you need to improve click-through rates and Quality Score (don't forget your ROI from advertising) this is definitely a resouce to check out.
The tool aids users in identifying a list of high-traffic keyword niches related to their business, service or product. Search marketers are then able to designate which of the keyword niches are relevant and which ones aren’t. The Negative Keyword Tool then saves any keyword terms deemed “negative,” and suggests additional, related terms that have a high likelihood of getting matched against the ad groups within 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.”
