Search engines look through your web site and collect information about the content. Anywhere from 1-6 weeks will allow initial registration time for engines. Results on sales vary from 1 month to 12 months. The internet is a BIG place with millions of web sites. You may have to be patient and play the game, but after the ball starts rolling things pick up.
Items have product numbers and an ordering button.
The customer clicks on the ordering button and then selects how many items he wants. He can either check our or continue shopping after that point. When he checks out, the shopping cart interface sends him a copy of the order and the original order to your e-mail box. You, as the merchant, then process the card number and that's it.
