When starting a keyword research, a list of raw keywords must be created. While you can think and jot down a few keywords of your own, Search engines can provide some extra keyword suggestions to build up a list of raw keywords. All major search engines provide suggestions while you type in the keyword. With the advent of Google Instant and Yahoo Search Direct, this option has been enhanced quite a bit. Also all major search engines provide Related Searches keyword suggestions. In Google, this can be found under, “More Search Tools” option. In Yahoo and Bing, these are visible at the top or side bar respectively. Google also has a Wonder Wheel option along option under “More Search Tools” which is quite helpful in finding interrelated keywords and new keyword groups.
