I know this sounds very simple, but can someone give me an explanation of what a keyword is and how it works, within an article. how does the computer know what your keyword is. I understand a human might know what it is by reading the context of the article. but how does the google spider know what the keyword is. for example I really like posting on the blackhat forum.People here are very helpful with your posting. Now to me the keyword is blackhat. But why would the computer not think that posting is the keyword as it comes up twice. sorry for the basic question but its something that i have not fully understood.
