Always thank folks for visiting and ask them to please return again. If you thank customers when they visit your store, do the same on the web. Simplicity is the product of profound thought. If visitors have to work hard to purchase products from your site, they won't. If it takes too much thought to buy something from your site, sales will be low.
Promotion is the ONLY way to be found.
Spread the word, on and off the web. Everything with your company name on it should have your URL printed also, it is always best for future site visitors to know your URL before they need it. All roads lead to you. Several URLs will always bring in more visitors than just one. Several different URLs and entry pages will bring more visitors to your site, if you promote each page and URL properly, you can double your site traffic.
