When you make your first sale, follow-up with customer. You could follow-up with a "thank you" email and include an advertisement for another product you sell. You can be more subtle including offer within your signature file.

Another way is to take your customer to a "thank you" web page right after they order. You should thank them for their order and next begin to tell them about another product you sell. You could also include a picture or graphic of your product.

2) UPSELL ADD-ONS

You could upsell to your customers. When they're at your order page, tell them about a few extra related products you have for sale. They could just add it to their original order.

2. Gain extra credibility by using terms your readers may not understand, but can follow by explaining them in simple terms. This will show you're an expert.

3. Reveal how excited you are about product. You could use words or a picture of yourself looking very excited.

4. Tell your target audience you were in their current position. Next, tell them how your product pulled you out of that position.

5. Challenge your readers at end of your ad. Make a bet with them; if your product doesn't solve their problem, offer them a free product in return.
