Create trust with your prospects by telling them
something they already know is true. They'll know for sure you're not lying and begin to trust you. For example, you could say, "I know you want to increase your sales..." Another example, “I know you want something for nothing..."
 

Design your packaging so it sells your products.
Utilize colors and lettering that make your product more attractive to your prospects. You don't want colors that make it hard to read. For example, you don't want dark blue letters on a black background.
 

Provide testimonials from satisfied customers in
your ad. The testimonials should include specific and believable results your customers have received. For example, you could say "(their name) from Ohio said..." Another example, "A milkman from Miami, Florida said that…"
 

When you make your first sale, follow-up with the
customer. You could follow-up with a "thank you" e-mail and include an advertisement for other products you sell. You could follow-up every few months. For example, you could attach or link to an e-book catalog on all the product you sell or resell.
 

Don't make your banner ads look like ads. Most
people ignore banner ads. Design them to look like content and have people click to read the rest. For example, you could say, "How To Increase Your Sales By 200% by Larry Dotson. To Read Click Here!"
 

Attract a lot more customers by giving them clear
ordering instructions. Give them all the information they need so they can complete their order easily. For example, you could say, "Please fill out all of the order form below. We accept all major credit cards and online checks. Please click the "Order" button only once. You don't want to get double charged."
 

Combine your products or services into one big
package deal with offerings from other businesses. You could share a web site and advertise the pack- age deal which would mean double the traffic. It could be one or more business. If the business is your competition, you would want to use a neutral product.
 

Submit the free things you offer to online freebie
directories. They usually get a lot of traffic because people like to get things for free. Of course include your ad in the freebie. Sometimes freebie directories allow you to mention your business with your free listing too.
 

Motivate your prospects to imagine a persuasive past
memory. Bring up your reader's past memories to trigger a positive or negative emotion that will help sell your product. Of course the memory should be something everyone would have had sometime in his or her life. Example: Do you remember when you first were attracted to someone?
 

Use Online Diaries Instead Of Testimonials

Have your customers publish an online diary instead 
of giving you a testimonial. The diary would include 
regularly updated entries of how customers are using 
your product to improve their life. You could give 
customers a free product or a rebate in exchange for 
them publishing it online. 
 
Your customers could write diary entries about goals 
they have reached using your product, the positive 
emotions it's given them, the fears and worries your 
product has taken out of their lives, how bad their 
lives were before they bought it, how it has helped 
other people in their lives, etc. 
 
Your customers could update it daily, weekly or 
monthly. It will depend on how often they use your 
product. You could publish the diary right in your 
ad or link directly to the diary. You could provide 
the people with web space for writing the online 
diary or have them e-mail you the diary entries for 
you to publish. 
 
You can make the online diary extra persuasive by 
also including customer's personal profile, pictures, 
online video of them using your product, net audio 
of them talking about your product, even scanned 
handwritten letters, etc. 
 
An online diary would likely outsell the common 
testimonial because it's updated on a regular basis 
and reveals more personal information. A diary is 
considered private which would make people more 
curious to read it and believe it's legitimacy.
