the keywords is important in seo, but i am a little confused that what is the real keywords. the title of the article? the description in meta? the text used in backlinks? or the words repeated in the content? as i tried to build my website, the title of the article does not be a keywords in google, but the title of my index page does be a keywords in google, and the description seams useless, is that right? hope someone can help me solve the problem. what i exact mean is what is the keywords that can be showed on search engine, like google, usually, the title of index can be searched on google, but i am not sure whether the title of article or description can be keywords displayed on google, and are these important in seo?
