Smarter Targeting with Meta Ads: Your Guide to Detailed, Custom & Lookalike Audiences
Running ads on Meta can sometimes feel like trying to assemble IKEA furniture without the manual — you’ve got all the pieces, but where do you even start? With so many buttons to press, drop downs to uncover and settings to toggle, it’s easy to feel a bit lost. But when it comes to getting real results, it’s less about bells and whistles, and more about who you’re actually showing up for.
This guide breaks down the three go-to targeting tools that help us make sense of Meta ads — Detailed Targeting, Custom Audiences, and Lookalike Audiences. Plus, we’ll dive into Meta’s newish AI tool — Advantage+ — and how to use it without feeling like you’ve handed over the reins completely. By the end, you’ll have a clearer path to reaching the right people, without the guesswork.
Detailed Targeting: What It Is and What’s Changed
This is where most people start. Detailed Targeting is Meta’s way of letting you hand-pick the type of people who’ll see your ads. It’s all about narrowing in on your ideal audience based on what they’re into, how they interact online and key traits like age, location and lifestyle. Think of it as your toolkit for reaching people who are more likely to care about what you’re offering.
It works by letting you choose from a huge list of interests, behaviours, and demographics — things like hobbies, shopping habits, life events, job roles, and even the devices they use. Basically, you’re building your dream audience from the ground up.
You can still target:
- People who follow specific pages
- Interests like travel, parenting, skincare, side hustles — the works
- Device types, age, location, and a bunch more
Here’s the curveball — as of March 2025, Meta removed the option to exclude people when using this method. So if you were used to saying “yes to dog lovers, and no to cat fans,” that option is off the table now. Meta reckons removing exclusions makes campaigns perform better. Their data backs it up — but we get it, it takes a mindset shift.
So how do you keep your targeting sharp?
- Focus on the audience you do want to attract
- Use Custom Audiences to exclude people instead
- Head to account settings for any more specific blocks (like industry-based restrictions)
Custom Audiences: Your Secret Weapon
This is where things get a little more familiar — in a good way. Custom Audiences let you target people who’ve already interacted with your business in some way. Maybe they visited your website, liked one of your posts, or opened an email. They’ve already shown some interest, which means you’re not starting from scratch — you’re following up.
It works by pulling data from your existing touchpoints and turning it into a tailored audience. You can reconnect with people who know your brand, nudging them closer to taking action. This makes your ads feel less like a cold call and more like continuing a conversation.
You can create Custom Audiences from:
- Website traffic (thanks to Meta Datasets tracking visitors)
- Engagement on your Instagram and Facebook content (likes, comments, video views, etc.)
- Your email list or a list of past customers
- Product views, add-to-cart actions, form submissions, and event RSVPs
Why do we love them? Because they’re warm — they already know who you are. You’re not introducing yourself; you’re just giving them a reason to come back or take that next step. Plus, you can use these audiences to exclude people from certain ads (like existing customers from a first-time buyer offer), so you’re not wasting spend.
Quick tips:
- Wait until your audience is marked “Ready” before launching ads — otherwise, you might miss them.
- Don’t leave them for too long — audiences can expire if they haven’t been refreshed.
- You can create up to 500 Custom Audiences, so there’s plenty of room to get creative with your segmentation!
Lookalike Audiences: Scaling Without Guesswork
If Custom Audiences are your inner circle, Lookalike Audiences are how you find more people just like them. Meta takes the data from your best customers, site visitors, or even your most engaged followers, and then searches for new people who share similar traits and behaviours.
It’s perfect for when you want to grow but still stay targeted. Instead of guessing who else might be interested, Meta does the heavy lifting and helps you reach fresh faces that are likely to care.
Here’s how it works: you choose a ‘source audience’ (like your top customers), and Meta uses that to build a new audience that mirrors them. You can adjust how closely the new audience matches the original, depending on your goals.
Size-wise, you’ve got options:
- 1% Lookalike = the closest match (highly targeted, smaller reach)
- 2–10% = broader reach, a bit less precise, but good for awareness
Want more conversions? Stick to 1–2%. Want to spread the word far and wide? Go for a larger percentage.
Just make sure:
- Your source audience has at least 100 people (1,000+ is even better for accuracy).
- You test different Lookalikes from different sources (like comparing an email list vs high-spending customers).
It’s one of the best ways to scale your ads without throwing spaghetti at the wall — smarter reach, fewer wasted clicks.
Meta Advantage+: The New Kid on the Block
Advantage+ might sound like something straight out of a sci-fi movie — and to be fair, it kind of is. It’s Meta’s AI-powered feature designed to take the guesswork (and legwork) out of setting up your ads. Think of it as an autopilot for your campaigns. You provide the creative (images, videos, copy) and your campaign goal (sales, leads, traffic), and Meta handles the rest — audience targeting, ad placements, and budget distribution.
It’s built to make things easier, especially if you’re short on time or not quite ready to dive deep into the finer details of ad setup. If you’ve ever felt overwhelmed by all the switches and settings, this is a more hands-off option that gets your ads up and running fast.
You’ll get the most out of Advantage+ if:
- You’re running eCommerce or lead generation campaigns
- You want to test and scale quickly without managing every detail
- You prefer a simpler, automated setup to get started
But let’s be real — it’s not magic. If your creative isn’t strong, or your offer isn’t appealing, even the best AI won’t save a weak campaign. Advantage+ can optimise what’s there, but it can’t create great content for you. It’s a tool, not a miracle worker.
A little reminder: while AI can lift the heavy stuff and help you move quicker, it’s no substitute for your own strategy and insight. Keep an eye on how your ads are performing, tweak things when needed, and don’t be afraid to switch back to manual controls if things aren’t feeling right. Advantage+ is there to help, not to take over completely.
Wrap-Up: Smart Targeting, No Guessing Games
At the end of the day, smart targeting is what turns a “meh” campaign into a money-maker. It’s about showing up for the people who are most likely to say yes, instead of throwing your message into the void and hoping for the best. Detailed Targeting helps you get started. Custom Audiences let you reconnect. Lookalikes help you scale. And Advantage+? That’s your shortcut, if you’ve already got a strong foundation.

Our Top Tips Before You Dive In
- Go slow — don’t try to tackle everything in one sitting
- Follow each section fully before jumping to the next
- Don’t get overwhelmed — even seasoned pros check things twice
- Make sure your budget is in a healthy place before hitting publish — when switching to a lifetime budget, Meta often defaults to $350, so always double and triple check before going live
- And remember, nothing is permanent — everything can be edited, adjusted or turned off if needed
- If you’re ever unsure, ask for help — it’s always better to check than to guess and burn through your budget
