A wide variety of options are available for performing keyword research, including tools provided by the search engines, tools developed by third parties, and tools for complex keyword analysis of terms culled during research.
Things to Keep in Mind :
It is important to keep in mind that when you are using the various keyword research tools to brainstorm keywords, they are all based on relatively limited data. You should be aware that each tool will provide different search count numbers than the other tools. Rather than focusing on the exact search count of various terms, you should think of each tool as a good way to get a general comparison of two search terms, or of groups of terms, relative to one another. For example, if you compare two terms and see that one term is more popular than the other because it returns a higher search count, you at least know that Term A may be more popular and searched for more often than Term B, but you can treat the search count values as only (rough) estimates. If you are just starting out with keyword research, consider starting with the Google AdWords Keyword Planner (which is free with an AdWords account) and at least one of the paid tools, such as KeywordDiscovery.com. This will give you a rich, varied data set with which to begin your keyword research. Over time you can experiment with the other tools and adjust your process as you find tools that you prefer for one task or another. In addition, as you look at these keywords, keep in mind the semantic aspects of search, and the probable intent of the person performing the search. You don’t want to simply slap popular search terms on various pages of your site. You are using the keyword research information to provide you with insight into how your potential customers think, but you need to take into consideration many other inputs as well.
Keyword Research Data from the Engines:
The search engines provide a number of tools that can help you with keyword research. Many of these are not designed specifically for that purpose, but they can be used to obtain interesting keyword research information if they are used in the right manner. The data in these tools show the number of pages that are related to a search phrase, not the number of searches on the phrase. This is still a useful indicator of the importance of a keyword phrase as more web pages tend to get built for more popular topics.
