If you write articles online, you have probably tackled the issue of how to get traffic to your articles. Writers have found various ways to do this; either by being very savvy with marketing their work on social media and other avenues, including guest blogging and participation in forums, or you study keyword research. Keyword research is the avenue I've found to be effective in getting traffic to my articles.
The basis of using keyword phrases for driving traffic is rooted in one sound piece of logic: No one will find your work if they are not looking for it. You have to know what people are looking for and how they are going about looking for it. You have to know what they are going to type into search.
But that's only half of it. You craft the title that reflects what is being looked for, then you have to give people what they want and need. This means writing an article that is informative, detailed and easy to read. Otherwise, no one really wants to read it. It's not enough to find your article, they have to get something out of it.
It should be noted that Google is getting good at finding out what your article is about. This has led to what is called Semantic Search; Google can figure out what is the basic thing people are looking for, the various meanings of keywords used to find something in their search engine, and matching it with what you've provided in your article. In other words, it's not just about the keywords you use but the gist of what you have written and what people are looking for; I have articles that get traffic because of this, because Google figured out what the article is about and what people were looking for and matched it up in the search results. You can go into the study of Latent Semantic Indexing and Semantic Search if you want, but I'm not going into it here; if you are thoroughly covering the subject matter in an article, these things will come out in the article.
