Start with the general term for which you are looking, and enter it in one of the free keyword research tools. The Google keyword tool is useful, except that you cannot copy the numbers — only the keyword list. Put your keyword list into a spreadsheet program to track your activities and help you to identify the best keywords.
Look at the traffic for the keywords as you go down the list; around 5,000 a month or fewer searches will give you the most likely overlooked terms. However, rarely will you find very good SEO keywords in your first general list. The real secret to finding the overlooked ones is to find sub-phrases of the main keyword group with high traffic, type them into the Google search tool as mentioned above, and then look at the words you get.
