Keyword research is the most important aspect for the ranking. There is no need to waste time convincing you that the keyword research is one of the highest return SEO activities that are essential to your marketing success. There is also no deficit of great articles that give you very precise instructions as to performing a professional keyword research, ranking high for the thousands of targeted search terms & vastly increasing your traffic from Google.
But here is an interesting observation: each of these examples will give you a somewhat distinct set of instructions. Start with a long tail keyword that is related to your niche. It has to be something that people search for and your plan is to be among the top results.
