How can you refine your keywords based on preliminary results?
Scanning the 'snippet' or summaries returned by your first searches can give you good ideas for keyword refinement. You might notice an evocative phrase that better describes your target. Additionally some search engines, Such as Teoma.com, suggest associated keywords when they return results. Combining these techniques can quickly get you focused on the right power words for your search.
