Google Suggests

Google Suggest gives suggestions for search queries in real-time, based on what other users have searched for using the same keywords. It’s the function in Google that suggests ‘I want to break free’, ‘I want that dress’ and ‘I want that trend’ when you start a query with ‘I want’. These suggestions can be useful for uncovering more sophisticated keywords with real intent, helping you discover new phrases your users are actually searching for. You can use this as a research tool, both for generating new keywords for PPC or SEO, and for taking a look at how Google searches might lead to your competitors (with a view to usurping their ranking with your own site in time).
