I like this trick and use it each time in my keyword research. I came up with it after discovering the great AutoPagerize user script for Greasemonkey. It stimulates a lot of ideas quickly. In keyword research, where creativity is still a key ingredient, this trick not only makes for a great “jump in” point but also provides a bunch of terms that have a higher probability for success.
Take one keyword or keyword phrase and enter it into Google like this: allintitle: ~coffee products where coffee products would be the term you’re looking to expand upon. By using the tilde (~), you’re asking Google to display synonyms and related terms that Google may be using in their algorithm.
