An Introduction to Keyword Research Using Free Tools
I often find that keyword research is an overlooked part of the SEO process. Many SEOs will tend to stick with using Google’s Adwords Keyword Tool and as a result, they will most likely be targeting the exact same keywords as the competition. The ultimate goal with keyword research is to find those juicy, low-hanging fruit - the long-tail keywords. Long-tail keywords are sometimes defined as keyword phrases containing multiple words of four or more. However, this is not how I like to define them. For me, the long-tail keywords are those that have lower volumes of traffic and are less competitive to rank for. In other words, they may contain multiple words or they could contain as few as two words.
