A proper Keyword research is the most essential ingredient of a successful SEO campaign. An expertise keyword research professional can very well determine the fate of your search engine rankings. So keyword research is the vital part of SEO which needs to be done with care, patience and skil.
Keyword research mainly includes the identification of the right keywords which are more suitable for your website, so that your website gets more chances for ranking in search engines for the selected keywords. After finalizing the keyword research process, you just need to start optimizing your website for these keywords.
Keyword research needs to be done with much precision and you need to study a lot about the website and the industry the website is related to. While doing a keyword research you should also need to take care of other factors affecting keywords such as location, seasonality etc. Most of the time keyword research is a semi automated process which requires manual research as well as automated work with the help of various tools.
There are quite a good list of keyword research tools and the first one that comes to my mind is the Google Keyword research tool which is very much easy to use and free of cost. This keyword tool gives search information for keywords such as its search volume, Avg CPC, competition etc. But these results are mainly based on Google search results. To get search results based on the other major search engines you needs to go further with some good paid keyword research tools.
