AI Targeting - How to Build Audiences That Convert

Running ads used to be simple. You picked a few interests, set an age range, and hoped for the best. But as competition has grown, the old way of targeting has lost its edge.

Today, building audiences that convert takes more than guesswork. You need precision, insights, and the ability to adapt quickly. That’s where AI targeting comes in.

AI doesn’t just make targeting easier, it makes it smarter. By analysing data, spotting patterns, and predicting behaviours, AI helps you build audiences who aren’t just clicking… they’re converting.

Why Targeting Matters More Than Ever

Even the best ad will flop if it’s shown to the wrong people. Poor targeting leads to:

• Wasted spend – Paying for clicks that will never buy.

• Low engagement – Ads ignored because they’re irrelevant.

• Skewed data – Harder to tell what’s working when your audience is too broad.

Great targeting flips the script. Your ads reach people who:

• Need what you offer.

• Are primed to take action.

• Find your content relevant and valuable.

AI gives you the edge by filtering noise and focusing only on those who matter.

How AI Improves Audience Targeting

Here are five ways AI transforms targeting:

1. Behavioural Analysis

Instead of just demographics (age, gender, location), AI looks at how people behave online:

• What content they engage with.

• How often they visit your website.

• What triggers conversions.

This creates audiences built on actions, not assumptions.

2. Lookalike Audiences 2.0

Traditional lookalikes copy your existing customers. AI-enhanced lookalikes go further by factoring in behaviours, sentiment, and micro-patterns. The result? More accurate matches.

3. Predictive Targeting

AI can forecast which prospects are most likely to convert based on early interactions. Example: users who watch 75% of your Reel are more likely to buy than those who drop at 3 seconds. AI can automatically build audiences around that.

4. Sentiment and Intent Signals

AI analyses language in comments, searches, and reviews. Someone commenting “Where can I buy this?” signals stronger intent than someone commenting “Cool.” AI helps you prioritise the former.

5. Dynamic Segmentation

Instead of static lists, AI constantly updates audiences. If someone shifts from “casual browser” to “engaged prospect,” AI moves them into the right bucket in real-time.

Practical Example: An Online Fitness Coach

A coach selling workout programmes struggled with broad targeting. Ads brought clicks but few sales.

With AI:

• They analysed which content types drove the longest video watch times.

• Built audiences of people who saved, shared, or clicked links.

• Created lookalike audiences from those high-intent actions.

The result?

• Cost per lead dropped by 40%.

• Email list grew by 1,200 in 6 weeks.

• Conversions doubled.

Step-by-Step: Building Audiences With AI

Here’s a process you can follow to start building smarter audiences:

Step 1 – Gather Data

Export metrics from your social platforms, website, and email list.

Step 2 – Feed Into AI

Input engagement and conversion data into AI tools (or use a prompt with ChatGPT).

Step 3 – Identify High-Intent Actions

Ask AI to highlight which behaviours signal buying intent (e.g., saves, long video views, repeat site visits).

Step 4 – Build Custom Audiences

Create segments based on those signals in Ads Manager or your CRM.

Step 5 – Test & Refine

Run small-budget campaigns, track conversion rates, and let AI learn and adjust.

Advanced AI Prompt (Copy & Paste)

Here’s the master prompt you can drop into ChatGPT, Claude, or another AI tool to build converting audiences:

“Act as my advertising strategist. My business is [insert business type]. Here are metrics from my recent campaigns: [paste data]. Please:

1. Identify which audience behaviours signal high buying intent (e.g., long watch times, link clicks, saves, shares, repeat site visits).

2. Suggest how I can segment my audience into three categories: awareness, engagement, and conversion-ready.

3. Recommend how to build custom audiences in Ads Manager based on these signals.

4. Create lookalike audience suggestions for each category.

5. Propose a £50 test plan that balances organic content and boosted posts to grow these audiences.

6. Suggest how I can use AI to update these audiences dynamically over time.”

This turns AI into your personal targeting strategist.

Common Mistakes With Targeting

• ❌ Over-relying on demographics – Age and location aren’t enough.

• ❌ Boosting weak posts – Data from bad content leads to bad audiences.

• ❌ Ignoring intent signals – A click is not the same as a comment asking for price.

• ❌ Failing to refresh audiences – Static targeting quickly goes stale.

Tools to Support AI Targeting

• Meta Ads Manager – Custom and lookalike audience building.

• Google Analytics 4 – Behavioural tracking.

• Sprout Social / Hootsuite Insights – Engagement analysis.

• ChatGPT / Claude – Run advanced prompts like the one above.

Why AI Targeting Is the Future

The days of “spray and pray” ads are over. Algorithms are too smart, competition too fierce, and audiences too savvy.

AI targeting gives you:

• Precision – ads reach those most likely to convert.

• Efficiency – less wasted spend.

• Scalability – you can grow faster by replicating proven audiences.

Brands who embrace AI targeting will outpace those still guessing.

Final Thoughts: Smarter Targeting, Better Conversions

Building audiences that convert isn’t about throwing money at ads. It’s about understanding intent, recognising signals, and letting AI do the heavy lifting.

With AI targeting, you can:

• Build smarter custom audiences.

• Spot behaviours that predict buying.

• Scale lookalikes with confidence.

• Turn data into conversions.

And here’s the truth: while the system is powerful, most business owners don’t have time to analyse, segment, and optimise audiences weekly. That’s where I come in.
