Keyword research is the process of identifying the keyword phrases that your potential customers type into search engines to find information about your products and services. The goal is to identify the most popular and relevant keywords that you can target for search engine optimization and paid search.
There are many keyword research tools out there, but none of them are perfect. In fact, if you test the same keyword phrase in each of the top keyword research tools, they will return drastically different search volume estimates. So when you use these tools, you should understand that the goal is not to estimate the precise number of annual or monthly searches – the goal is to identify which keywords phrases are more popular than others.
