All you would have to do is write a decent review and use some Long Tail marketing keywords scattered inside of it. Do it in a way that the reader doesn’t even know you’ve slipped in 20 long tail keywords. Let the article flow naturally with a clear tone of honesty…as if you were talking to a friend. People who read your review want to feel a connection or a solution or a even a need to buy that product. This is where you use those Long Tail Keywords.
But it’s still very useful for getting search volume data (provided your account still shows this), which is helpful when choosing which of the many keywords you’ve found to focus on (although you should take these estimates with a pinch of salt, they are still useful in indicating the relative search volumes of different keywords, even if the absolute estimates are a little off).
Long Tail Pro is a keyword research tool that helps you quickly find low competition keywords for your website. In particular, the tool is built for people doing SEO (search engine optimization) as opposed to people doing paid ads (Google Adwords PPC). I'm sure there are some advertisers that use the tool for paid ad keyword research, but the tool was built for SEO keyword research.
