Well that an open ended question. Within this community, there are a lot of great information on selling. Read suggestions from here, and use what work for you. There is not cookie cutter way. I have tried suggestions, mixed it up till I found what works for me. You need to know the product you are selling. The same selling technique will not work on everything. Know your audience, target your listings to them. Again there is a lot of great information here. Your question is as I said very open ended, and has tons of great answers from everyone. If you pin point more on what you need help, I am sure the community can give you suggestions.
