Advanced Prompting: Chain-of-Thought, Trees & Recursion

This is the third episode in our series on the art of prompting. The first two were about the fundamentals: how to write a prompt and use essential prompting techniques effectively. Now it’s time to level up.

This article covers advanced prompting techniques that unlock complex reasoning, multi-step problem-solving, and self-improving outputs. These aren’t techniques you’ll use every day—but when you need them, they transform what’s possible with AI.

Advanced prompting techniques or how to write a prompt that delivers results

When tasks require complex reasoning or strategic decision-making, two techniques stand out: Chain-of-Thought (CoT) and Tree-of-Thought (ToT) prompting. Understanding when and how to use each unlocks dramatically better results.

Chain-of-Thought prompting

Chain-of-thought prompting guides the model through sequential, step-by-step reasoning rather than jumping to conclusions. When a task involves layered logic or multiple pieces of information, this helps the model reason more clearly and explain itself along the way. Think of it as showing your work in math class—each step builds on the previous one, creating a transparent logical path.

When to use Chain-of-Thought:

The difference in action:

Without Chain-of-Thought:

Which of our marketing campaigns performed best last quarter?

Result: The model might guess based on incomplete analysis or surface-level metrics.

With Chain-of-Thought:

Analyze our Q3 marketing campaigns using this process:

  1. List each campaign with total spend
  2. Calculate the cost per lead for each
  3. Calculate the ROI for each campaign
  4. Identify the campaign with the best ROI
  5. Explain why it outperformed others, considering both quantitative metrics and qualitative factors

You’ve built a chain. The model is now reasoning before handing out answers. This is especially useful for performance reviews, business analysis, and debugging processes. It won’t speed things up in simpler tasks like summarization or fact recall, but when you need clarity and logic, it’s a game-changer.

Result: The model reasons through each step, providing transparent logic you can verify and trust.

Pro tip: Chain-of-thought prompting becomes even more powerful when AI can access your actual campaign data instead of working from memory or uploaded files. By connecting your marketing platforms (Google Analytics, HubSpot, Facebook Ads) through Coupler.io’s AI integrations, your CoT prompts can analyze real performance metrics, calculate accurate ROI across campaigns, and identify patterns in actual conversion data—not hypothetical scenarios.

Key principle: Break complex questions into a numbered sequence of sub-questions. Each answer becomes context for the next step.

Tree-of-Thought prompting

Tree-of-thought prompting takes it a step further. It asks the model to generate multiple solution branches, evaluate each path independently, then compare and recommend. Instead of one linear chain, you’re exploring a decision tree.

When to use Tree-of-Thought:

The difference in action:

Single-path thinking:

Give me a good way to reduce churn.

Result: You get one idea—maybe it’s good, maybe not. No comparison, no alternatives.

Tree-of-Thought approach:

Suggest three retention ideas we haven’t tried. 

For each, explain expected impact, ease of implementation, and potential risk. 

Then recommend the best fit for a B2B SaaS company with yearly contracts.

Now you’re getting depth, not just answers. This kind of prompting is perfect for strategic planning, product ideation, decision-making, and anywhere you want to weigh options. It’s not ideal when you’re just looking for a direct answer, but when your goal is high-quality judgment, it shines.

Key principle: Ask for multiple solutions upfront, require evaluation criteria for each, then request comparison and selection.

Prompt chaining and decomposition

When the task is complex, breaking it into smaller parts delivers cleaner, more accurate results. Prompt chaining allows you to feed the output of one prompt into the next. 

Instead of asking the model to go from transcript to email in one step, you might do this:

Extract action items from this transcript.

Summarize those into 3 bullet points.

Add a closing line and CTA and turn it into an email.

Decomposition takes it further by splitting the task upfront into clear steps.

Something like:

This method is especially valuable when working with automation workflows or building repeatable prompt templates across tools.

Meta-prompting = prompting the model to generate or improve prompts.

It’s ideal to use meta-prompting when:

Let’s look at an example

You can even ask:

This approach transforms prompting from a one-off skill into a scalable system. 

It helps:

In a world where every second of clarity translates into faster insights and better decisions, meta-prompting moves you from “trying prompts” to engineering predictable outcomes.

Techniques to reduce hallucinations

AI models are known for confidently stating falsehoods (We know right!). To reduce hallucinations from the get-go, you can ask the model to:

We’ve seen hallucination rates drop significantly when prompts are built using chain-of-thought instructions or connected to normalized structured datasets.

Here’s why: when you upload a CSV, the AI interprets messy headers, inconsistent formatting, and missing values. When you connect data through Coupler.io, the AI queries clean, schema-validated data, and only returns what you ask for. It’s the difference between asking someone to read your handwritten notes versus querying a database. Even without the context, you will understand by looking at the prompt below that it’s working on chain-of-thought instructions.

Recursive prompting techniques

Great outputs rarely come from a single prompt. The best results emerge through iteration—using AI to refine its own outputs in successive rounds. This is recursive prompting: a systematic approach to improvement.

Let’s start with a typical first-attempt prompt and see why it falls short:

❌ Initial Attempt (What most people do):

What’s wrong here?

This isn’t a bad prompt because you’re lazy—it’s incomplete because you haven’t taught the AI what “good” looks like for your specific context yet. That’s where recursive techniques come in.

Self-improving prompts

Instead of accepting the first output, engage the AI as a collaborator in refinement. Ask it to critique and enhance its own response.

You can even create meta-loops:

Here’s a first draft. Rewrite it with 20% more emotional appeal, and suggest 2 alternate openings.

Or,

Review the following email for tone, clarity, and brevity. Then return a revised version and a bullet list of changes.

The pattern: Generate → Critique → Refine with added context → Repeat as needed.

Iterative refinement loops

Here’s the fundamental problem: AI doesn’t know what “great” looks like for your specific context on the first try.

When you write a single prompt and accept the first output, you’re essentially asking AI to:

…all in one shot, with limited context.

That’s not how human creativity works. So why expect it from AI?

The best copywriters don’t write once. They draft, critique, refine, and polish. Iterative refinement simply translates this professional process into a structured prompt strategy.

The logic is simple: Each round adds a layer of sophistication that single prompts can’t achieve. Think of it like sculpting: the first pass creates rough shape, then each refinement reveals more detail.

Each loop adds a layer of sophistication that a single prompt can’t achieve.

Think of it like sculpting: the first pass gives you the rough shape. Each refinement reveals more detail, more nuance, more impact.

Break a prompt into steps:

  1. Generate
  2. Review
  3. Improve
  4. Reformat

This is how you get from “okay” to “outstanding,” especially for copy that needs both creativity and compliance.

Example Loop:

1. Write a Facebook ad for Coupler.io's data integration platform.

2. Ask: How can this be more persuasive for digital marketers from agencies working with clients from the US and UK? Focus on time savings and reducing manual reporting work.

3. Ask: What psychological trigger is missing here?

4. Rebuild.

Can you see how big a difference there is between the first ad and our rebuilt version? This iterative approach works for any business, not just Coupler.io. When your prompts can access live performance data from past campaigns, AI can suggest improvements based on what’s actually worked—not just best practices. That’s the difference between generic marketing advice and data-driven strategy.

With recursive prompting, you’re not just sitting back after writing once. 

You’re building feedback loops into the prompt itself.

Meta-loops: Asking for alternatives

You can create even more powerful recursive patterns by requesting variations:

Here's a first draft. Now give me:

  1. A version with 20% more emotional appeal
  2. A version optimized for algorithm engagement
  3. Your assessment of which performs better and why

This recursive approach works especially well for:

Key insight: Recursive prompting acknowledges that AI, like humans, benefits from iteration. First drafts are starting points, not destinations.

Bonus: Advanced prompt template

This is a meta-prompt used to write better prompts. Use this when you need to optimize complex prompts or create systematic prompt workflows.
