Write Garage | Using This Obscure Sales Technique in Your Book Blurbs and Ads Will Make Them Irresistible

There is a guy named Keenan who wrote a book called Gap Selling. He hosts a LinkedIn Live every week where people call him to try and sell him products using his own method. And ironically, you'l learn lots about fiction ad creative and blurb creation even though, the Lives have nothing to do with the two (if you know what you're looking for).

His entire business focuses on helping account executives. These are the sales people who take meetings from Sales Development Representatives (SDRs) and move a prospect from low interest to a signed contract. This logic holds true whether you are closing a multi-million dollar deal or a 50k a year contract.

The foundational aspects of gap selling apply to any niche, including writing ad creatives and book blurbs. For any sale to occur, there must be a gap between the reader’s status quo and their desired state. The gap is the only place where the sale happens.

The Two Layers of the Gap

I divide the gap into two distinct layers to understand the mechanics of the sale. The deeper layer is the business problem. If an author is running Amazon ads at a 1.3 times return on investment, they have a business problem. They lack the margins to hire a team while remaining profitable. This is a deep, structural issue.

The surface layer is the technical problem. This is the struggle of how someone actually does a thing. In the Amazon ads example, the technical problem is the struggle with keyword discovery.

Most of the time, when you start talking to a prospect, you do not know the business problem yet. You only see the status quo of low ROI and the desired state of better ROI.

Translating the Gap to Fiction

To sell a product or service, you must identify the problem that the service solves. A book is an entertainment product, so it operates differently. A book is emotion packaged in the form of paper. The reader is trying to consume a specific form of emotion. They are either escaping from something or running towards something.

You must analyze the current emotional state of the reader to find the gap. I have observed that during hard times, such as war or economic instability, darker books often see a decline. Readers move toward lighter genres like Regency romance or cozy mysteries to escape into a world that feels safer. When times are good, darker genres experience a resurgence.

The current status quo for many readers is a state of being scared, tired, and busy. People feel they have no time for themselves and cannot shut their minds off because of the constant flow of information. Their desired state is to be relaxed and to forget their surroundings. They want a moment on their bed at the end of the day to read for an hour and relax.

This is the deeper psychological movement you must capture in your ads.

Targeting the Emotion Directly

There's an author I'm following who writes vigilante justice and revenge thrillers; and she leverages this wonderfully. Her ads are emotionally charged and often target specific feelings about the patriarchy or the darker side of human nature. She might start an ad with a line about refusing to move over on a park bench and then pivot directly to the book.

In a niche like cozy mystery, the emotional charge is equally strong. Many readers use these stories specifically to fall asleep. You can see this on YouTube where authors post AI audiobooks and the comment sections are full of people saying they use the stories to shut their minds off at night.

Your ad can cater to this emotion directly. You might start with the reality of not being able to fall asleep and then introduce an eight-book series set in a small town featuring an ex-correctional officer turned baker. This tells the Facebook algorithm to find people who are currently experiencing that specific emotional struggle.

You are moving people from being unaware that books can help them sleep to a state where they are ready to try the product.

The Logic of Loss

The thing that helped me understand gap selling for cold emails and blurbs is the concept of loss. When someone is at a status quo of being stressed and they want a desired state of being relaxed, the gap is defined by the fear of loss. The reader takes action because they fear the loss of not achieving that desired state.

This fear moves your book from the bottom of a to-be-read list to the very top.

In crime and mystery fiction, the gap is often overt. One of the primary things readers get from books is the experience of knowing things. They want to know how characters end up and how the world functions. Fans are desperate for George R.R. Martin to finish Game of Thrones because they want to know the resolution of the world. The status quo is not knowing, and the desired state is knowing. The loss is the experience of never getting to find out.

Deconstructing the Blurb

I look at top-selling books to see how they create these gaps. One book currently ranked high in the Kindle store introduces a character named Chloe. The blurb establishes her desired state immediately as a quiet life, a new home, and no more drama.

The disruption occurs when she steps in to help an elderly neighbor during a violent altercation. This event crowbars a gap into the reader's mind. Her peace begins to crumble and creates conflict. For the reader to ignore the book, they must accept the loss of not knowing if Chloe ever gets her peace back.

The blurb then agitates this gap further. It mentions that Chloe is not the only neighbor keeping secrets and that someone knows the truth about her past. This is a second disruption that threatens her desired state. As whispers turn to threats, the author reveals that Chloe has been in this situation before and not everyone made it out alive.

This use of backstory drops hints of a lived world without telling the reader everything, which forces them to engage with the gap.

Another example involves a story where a 13-year-old daughter named Barbara goes missing at a summer camp. The specificity of her age helps the reader connect. The desired state is for the parents to get their daughter back. When the blurb mentions a rich family that owns the camp and notes that this has happened around them before, it creates a second desired state for justice.

The reader now faces two potential losses. They lose the resolution of the missing child and the satisfaction of seeing a powerful family face consequences. The gap is strong enough to carry the book without a lengthy summary.

Scaffolding Your Creative Process

I use a spreadsheet to collect these elements because it makes it easier to formulate blurbs and ad creatives. Separating the status quo from the desired state and the disruptions allows my mind to pick up the data needed and ignore the noise.

This approach acts as a scaffold for those who are not naturally good at writing blurbs. A solid skeleton for the gap ensures the rest of the copy will follow. You can feed these principles and your specific story details into an AI and ask it to write sentences that capture this movement.

The goal is to make the gap feel so strong that the reader cannot bear the loss of not picking up the book.

PS: If you create book ads and have trouble figuring out how to structure hooks, first lines, imagery, the lower-third (headline, call to action & description)...
