We created a rather nice little keyword tool many moons ago called Seed Keywords. The idea was simple, create a scenario or problem and ask people to provide the search phrases they would use to solve it. We figured that getting real search phrases from real people in response to a very specific problem would add some spice to the mix, and it did. It's proved to be a useful tool in people's SEO and search marketing armoury.
Recently a number of bloggers have picked up on the tool and because of this the traffic to it has dramatically increased. It's just another example of how creating content or something useful creates interest in your website, and for interest in your website read links to your website, and we all know that links are important, right?
So, if you're doing keyword research and you're not sure what people might be searching for, give Seed Keywords a try, it just might give you some valuable insights into what your customers are searching for.
