This isn't even a reasonable question anyway. Next they'll start asking us 'What is an Onion?"
OP - the whole darn site is dedicated to promotional strategies and tactics to rank websites and/or find other ways to make money with your online sites. Sadly your question reflects a lot more than your lack of general internet marketing knowledge.
A good place to start is high school. There they will teach you to formulate solid queries with enough context to help us understand you're really asking a serious question. I think you were serious when you asked it. It's just not a question a "serious" person would ask.
Do some preliminary research, and come back to the table with something a little more solidly formed as a question, and we'll be happy to actually help. It's just that nobody can really help with your originally posted question since it's as vanilla as vanilla itself. Ask a real question OP!
