Please help me understand about keywords. I know what they are but how do they really help you? Why do you really need them. I want to know how many you should have as well. Does it make a difference if you only have one or two or would it be better to have many? Or is there a limit as to how many you can have? I honestly do not know and am trying to figure this all out as I am very interested in the whole SEO process. Much thanks to you.
