If/Then: This is one of the most commonly used opening paragraphs. Gary Halbert, one of the most important copywriters of the 20th century, used them in almost every one of his sales letters. It’s very simple, clear, and powerful. It lets people know what to expect. There’s also a very interesting belief structure that is built with this combo. If this, then that. It’s as if they need to meet some kind of prerequisite to get the benefit. An example of this would be: 'If you want to make more than $100,000 a year working just 4 hours a day, then this letter will show you how.' Very simple. If you want that, then here’s how you do it.", "2. If / Then + Authority: Even more powerful than the 'If / Then' key is the same concept but adding a figure of authority or credibility. For example: 'If you want to know a secret way to become almost invincible in a fight... then here I’ll show you what the gladiators and samurais used to do. And why you can do it too starting today.' One way to notice the power of these opening paragraphs is by removing the authority figure. In this case: the gladiators and samurais. That would change the paragraph to: 'If you want to know a secret way to become almost invincible in a fight... then here I’ll show you why you can do it too starting today.' As you can see, it doesn’t have as much impact as the version with the gladiators and samurais.", "3. Honesty: Being transparent is one of the best ways to get more customers. It also works with opening paragraphs. For example, one of Gary Halbert’s ads started like this: 'My name is Betty Adams, and the first thing you should know about me is... I’m not a doctor. I’m also not a nutrition expert. I didn’t go to college and I don’t even have a degree. In fact, the only thing I consider myself an expert in is...' And then it went to a subheading where she mentioned how she could help you lose 10 kilos in a very simple way. In this case, you can notice all the negatives she uses: 'I’m not a doctor,' 'I’m not a nutrition expert,' 'I didn’t go to school,' 'I don’t have a degree.' These four negative statements strengthen her claim about what she is. Now, this won’t always work for every sales letter. It will depend on your market and ideal customer. If your market isn’t skeptical, you don’t need to use this kind of paragraph.", "4. Sensationalist: This one is related to the sensational headline. Here’s where you’d say something like: 'Let me tell you this strange story about a man who was arrested because he had herpes.' It’s sensationalist. And sensationalism sells. It always has and always will. Without a doubt, the paragraph is strange and makes your reader think: 'How was someone arrested for having herpes? What did he do? What happened?' It keeps them hooked, addicted to finding out more. They need to know.", "5. Ask a Question: It makes people stop if they’re interested. One of the best opening paragraphs is this: 'Did you know that the long-term value of baseball cards is much higher than that of stocks and rare coins?' So when you talk to someone in the finance, investor, or related niches about this topic, they will be interested because it’s different and gets them ready to start the journey.", "6. Micro Openings: This paragraph should be short. Just a few words... so they’ll read the next one. This is because being brief makes it easy to read. And if you say something that puts your reader in the right mindset, this can be quite powerful. For example, if your product is targeted to a skeptical market, you can use a paragraph like the following: 'I was a total skeptic.' With this, you’re going straight to their mind, to their doubts. One that you can use effectively is: 'Imagine the following:'" ] return random.sample(techniques, k=random.randint(1, 3)) # Escoge entre 1 y 3 técnicas al azar # Al crear el prompt completo, incluye el tamaño y las técnicas seleccionadas def get_gemini_response(target_audience, product, text_type, length, mood, emotionality): product_mention = get_random_product_mention() mention_instruction = get_mention_instruction(product_mention, product) # Agrega esta línea model_choice = "gemini-1.5-flash" # Modelo predeterminado model = genai.GenerativeModel(model_choice) # Obtener técnicas aleatorias copywriting_techniques = get_random_copywriting_technique() techniques_text = " ".join(copywriting_techniques) # Instrucción específica para el tipo de texto format_instruction = "" if text_type == "Historia": format_instruction = f""" Write an engaging opening paragraph that introduces a relatable problem your audience is facing.
