  2. Know Your Customer by Name
  3. Write a Powerful, Engaging Headline
  4. Craft an Intriguing Introduction
  5. Elaborate You Sales Message Using Subheads
  6. You Should Constantly Be Connecting With the Customer

  10. Use testimonials from people you’ve helped
  11. Offer an incentive to help close the sale

First, identify your target audience

This is the MOST IMPORTANT element of your sales letter.

You cant write a weight loss program for someone who is slim, fit, and healthy.

They don’t need it.

The people who need such a program are the overweight and the obese.

Therefore, you should ONLY write your sales letter and your message to those who need it.

Know your customer by name

This is when they are part of your email sequence.

There’s no way you’ll know the name of your reader the first time they visit your site.

So, when collecting their email addresses by offering a lead magnet, collect their names also.

That way, when sending promotional emails to them, the email will feel personal and that will increase your conversion rate.

Write a powerful headline

This is the first thing a reader sees when they visit your sales page.

Therefore, it is important to use this element to capture your visitor’s attention and arouse their curiosity.

This is the only way they’ll get to read the second line of your sales letter and ultimately…

Get to the end of your sales letter to make a purchase.

Craft an intriguing introduction

Since your headline is to arouse curiosity in your reader to read the second line…

Your introduction should help them see that your letter will help them.

Pose the problem and let them know that you have a solution for them in the introduction.

Elaborate your sales message using subheads

Subheadings break down your sales letter and make it easier for your reader to read.

So, try to break down your sales letter by using subheadings so your copy does not seem daunting to read to your visitor.

Because they’ll click away.

Constantly connect with your customer

This is for your email marketing campaign.

If you abandon your customers after they signed up for your newsletter…

And the only time you engage with them is when you want to sell them something…

You won’t be successful.

Because you didn’t engage with them constantly,

You won’t get the sales from them.

Pose a problem… Give the solution

In your sales letter, pose the problem to your customer.

Then show them that you have the solution for them.

They’ll be more receptive to your copy.

Also, show them why you’re different from your competitors.

that’s why you should have a unique USP to let them understand that you’re different and that they’ll gain a lot from buying your product.

State the features and benefits

Always state the features and benefits of your product or service.

But, ensure you focus more on the benefits and how they will help your customers.

Because, although the customer wants to know about your products,

Their main problem is how your product will help them solve their problem.

Use bullet points

Using bullet points makes it easier for people to read and digest your content.

Especially when you’re writing a sales letter.

Bullet points make your reader flow when reading your copy.

Use testimonials

Your customers are skeptical.

So, it is important to have testimonials on your sales page that’s proof that your product has helped others and will help you too.

Sprinkle these testimonials all over your copy for massive effectiveness.

You’ll make more sales this way.

Offer an incentive to close the sale

An incentive can be things like bonuses and guarantees.

Add bonuses to your sales letter to arouse the greed emotion in people.

This will make them make a purchase because of the incentive.

Guarantees make the customer feel safe.

If the product does not deliver, then they can ask for their money back.

When you have these incentives in your sales letter, you’ll increase conversion.

Dont forget about the P.S.

Some visitors will first, after reading the headline, read the P.S

This is so that they can see what the offer is really about.

Therefore, your P.S. is a summary of everything they get.

So, always include a P.S. in your sales letters.
