How to Structure Facebook Ad Campaigns for Maximum ROI

Facebook ads’ campaign structure comprises three components: Campaigns, ad sets, and ads. They follow a three-level hierarchy: Campaign> Ad Set > Ad. Understanding these components gives you an edge in running your ads successfully. To give you a little preview of how the structure works, you set objectives at a campaign level, define Targeted Audiences, Budget & Schedule, Bidding, and Placements at the Ad Set level, and build creatives such as visuals, copy, CTAs, etc. at the ad level.

Having an in-depth knowledge of the Facebook ad campaign structure and its components enables you to organise your account into the three core funnels—prospecting, retargeting, and retention and choose between evergreen and experimental campaigns. 

A clean structure enables smarter budget allocation (CBO vs. ABO), simpler performance testing, less overlap, and more transparent reporting, which allows you to scale effectively.

This blog provides in-depth information regarding Facebook ad campaign structure, strategies, campaign creation, and more.

Glossary

• CBO (Campaign Budget Optimization): CBO is a Facebook setting where you set your total budget at the campaign level. Facebook automatically distributes this budget across ad sets based on their performance to get the best results.
• ABO (Ad Set Budget Optimization): You control the budget for each ad set individually. This setting gives you more control over testing audiences or strategies separately.
• Advantage+: Advantage+ is a Meta’s automation-powered campaign type that uses AI to optimize targeting, placement, and creative delivery for better performance with less manual setup.
• Dynamic Catalogue: A Facebook product feed connected to your ad account that allows you to automatically show personalized ads (like product carousels) based on what users viewed or added to cart on your site.
• Holdout: A group of audience intentionally excluded from seeing your ad. Advertisers use Holdout to compare performance and measure the actual impact of your campaign.
• Lift Test: An experimental test that measures how much of your results (like sales or conversions) can be attributed to your Facebook ads, compared to a similar group that didn’t see them.

Understanding Facebook Ad Campaign Structure

Facebook’s structure contains three main elements: campaign, Ad set, and Ads. The structure follows a hierarchical flow, with the campaign at the top level, multiple Ad sets within a campaign, and multiple ads within Ad sets.

Something like this:

All these three components make up the Facebook ad structure. Understanding each of them is crucial to running the ads as you want them to be for long-term success.

What happens at each level?

• At the Campaign level: You set an objective that aligns with your business goals.
• At an Ad set level: You set up targeting, which includes audience, budgeting, and scheduling.
• At an ad level: You create ad copies, images, videos, headlines, descriptions, etc.

We will discuss in detail each component in the following sections.

Importance of Facebook Ad Campaign Structure

Achieve your Business Goals

Following a campaign structure for your Facebook ads lets you streamline your focus and efforts towards achieving your goals.

How?

When you follow a structure, you set up an advertising objective at the campaign level. These objectives could be generating traffic, leads, conversions, or clicks.

Likewise, you can set up separate campaigns depending on your goals. One goal per campaign. This way, you can prevent overlap that affects the potential of your ads and 

precision of your marketing efforts.

Smarter Budget Allocation

Whether you choose Campaign Budget Optimization (CBO) or Ad Set Budget Optimization (ABO), having a structure helps the Facebook algorithm optimize your Facebook ads based on their performance.

Following a campaign structure also ensures you do not overspend or underspend on your ad campaigns.

Easier Performance Tracking

With a clear structure, you can attribute results accurately. You will understand what’s working: placements, creatives, retargeting.

You can track and compare metrics such as CTR, CPC, and ROAS across ad sets to identify the winner.

This way, reporting becomes easier when you scale up your marketing efforts.

Additionally, following a Facebook ads campaign structure avoids unnecessary learning phase issues, ensures data consistency, saves time, and reduces errors.

What Has Changed in Meta’s Campaign Structure in 2025?

Earlier, when creating a campaign,” you had the option to set up a campaign manually or use the Meta Advantage+ option, but now, you don’t have that option. 

You activate the Advantage+ option by choosing specific settings while creating your campaign. What does this mean? 

When creating a campaign, you trigger the Advantage+ option by selecting broad targeting, optimised placements, campaign-level budgets, and purchase events. This logic is inculcated in the campaign creation workflow.

All these signals put you inside an Advantage+ campaign.

Custom budget caps are also gone. With the new campaign structure, you do not have the control to tell the algorithm to spend only 15% of your budget on existing customers. 

You can use the custom audience exclusion option to exclude the existing customers and engaged audience from your Advantage+ campaign.

When targeting top-of-the-funnel prospecting, it is essential to exclude your existing customers. The Advantage+ feature allows you to retarget customers with specific post-purchase offers. There are more such feature updates from Facebook in 2025, to know more about these, ensure you keep check Meta Business Suite and Meta Business Help Center.

Now, let’s understand what happens at the campaign level of the Facebook ad campaign structure.

Campaign-Level Structure

The first step in running Facebook ads is creating a campaign. At this level, you will choose an advertising objective. 

Campaign objectives on Facebook are as follows:

• Awareness
• Traffic
• Engagamenet
• Leads
• App promotion
• Sales

When you choose Awareness, you tell the algorithm that you want your ads to reach maximum users and spread awareness of your product. This objective focuses on views and impressions.

Similarly, when you choose Traffic, the algorithm sends users to a particular destination, such as a website, app, Facebook shop, event, or Instagram profile. This objective focuses on clicks, landing page views, profile visits, calls, etc.

With Engagement, you can expect messages, post engagement, conversions, video views, etc.

When you select leads, you want the algorithm to generate leads for your business. This can include messages, calls, conversations, users expressing interest through forms, etc.

Further reading:  Improve Facebook engagement

Choose App promotion when you want new users to install your app.

The most common advertising objective is sales. When you choose sales, you are looking for conversions, catalogue sales, calls, etc.

Important: Choosing an advertising objective is paramount when creating a campaign. This objective, be it sales or leads, will make or break your Facebook ads. Before choosing, ensure the objective aligns with your business goals. Understand the purpose of creating the campaign, and the objective will follow. 

Now, let’s discuss how you can select an objective in Facebook Ads Manager:

Log in to your account >> select ‘Campaigns’ from the left-hand side menu >> click ‘Create’ >> choose campaign objective.

Before choosing the objective, you will see a dropdown menu titled Buying Type, which has two options: Reservation and Auction. Based on your selection, the objectives are displayed.

When you choose ‘Reservation,’ you can select from awareness and engagement. When you select ‘Auction,’ you can choose from all he objectives we discussed earlier.

What is Buying Type in Facebook Ads Manager? Auction: Auction is the most flexible and common buying type on Facebook. When you choose an auction, you compete against other advertisers to display your ads in real time. Reservation: This buying type is suitable for big companies. When you select this option, you buy ad campaigns at a fixed cost to achieve specific reach and goals.

I select ‘Auction’ and proceed with the objective ‘Traffic.’ The next step is to choose a campaign setup. 

Note: The campaign setup options vary based on your ad account activity.

You can choose Facebook’s recommended settings or a manual setup to control all the campaign settings at a granular level. After selecting, click on ‘Continue.’ We are going with Facebook’s recommended settings. 

You will see the following page. Here, you can confirm the preset recommended settings.

Note: This page will vary when you select the ‘manual campaign set up.’

This brings us to setting up ‘Ad sets.’ Let’s discuss it in the following section.

Ad Set Level Structure

At an Ad set level, you define the following:

• Audience: You create an audience by selecting location, age, gender, and other criteria.
• Budget: Set a daily limit or lifetime budget for the campaign. This budget indicates the average amount you’re willing to spend per day. 
• Ad scheduling: Set a start and end date for the ad to run. 
• Bidding:  Set bidding at the Facebook ad set level within the “Optimization & Delivery” section.
• Placements: Choose where your ads appear across Meta technologies. 

In Facebook Ads Manager, when creating ad sets, you add a conversion location, which means choosing a destination to which you wish to send the traffic. This destination could be a website, app, messenger, Instagram or Facebook profile, or calls.

In the next step, you can set budgeting and scheduling, which includes adding a daily budget and setting a start and end date for the ad.

Use the audience control, locations option, Advantage +audience, placements, and more.

After successfully configuring the location, budget, ad scheduling, etc, it is time to create an ad.

Ad Level Structure

At the ad level, you create ad copies and headliners, add images or videos, etc. Depending on the campaign objective, you can choose types of ads such as Meta Collection ads and Carousel ads. 

Here, you can add the destination URL, select the ad type (image or video), and set up tracking to monitor website or app events. We advise you to review some Meta Ads examples to better understand. 

The structure—Campaign > Ad Set > Ad—serves as the framework that organizes your goals, budgets, targeting, and creatives. When your strategy is mapped to a strong structure, it ensures better optimization, cleaner data, and more confident decisions as you scale or test. Let’s look at some key strategies to follow when creating Facebook ad campaigns.

Evergreen vs. Experimental Campaigns

What are Evergreen campaigns?

Evergreen Facebook ad campaigns run for a longer time profitably with minimal tweaking periodically.

For an evergreen campaign to produce desired results, you must establish a stable campaign structure, target audiences based on their specific trigger actions, and build custom audiences to ensure the ads stay relevant to new audiences.

A few examples of evergreen campaigns include:

Dynamic Retargeting ads

Dynamic Retargeting ads show ads to buyers who have interacted with the website or product in the past. 

These campaigns are easy to set up and offer a personalised ad experience for each buyer. 

This strategy also improves relevancy, reducing ad spend and increasing return on ad spend.

Dynamic Product Ads

Dynamic product ads show ads to a cold audience looking for a similar product. The Facebook algorithm finds new audiences and shares ads to those most likely to buy, resulting in new customers. Remember, this strategy uses broad audience targeting.

This type of campaign is proven to run longer, as the algorithm finds new audiences for your products.

3-Day Add to Cart Retargeting Sequence

When a shopper leaves an item in their cart, they’re already interested in your offer.

But, they might need a simple nudge to make that purchase.

 A simple solution is a 3-day retargeting sequence that shows progressively stronger offers over three days.

Create three custom audiences by days-since-add-to-cart:

• 1 day since visit.
• 2 days since visit.
• 3 days since visit.

Give each day a distinct incentive (e.g., Day 1 — free shipping; Day 2 — a coupon; Day 3 — a limited-time bundle or more substantial discount). Build three campaigns using those audiences, and make sure each campaign excludes the audiences for earlier days (Day 2 excludes Day 1; Day 3 excludes Day 1 & Day 2).

These are a few examples of evergreen campaigns that keep working for you and yield profitable results with minimal intervention from your end.

Now, let’s look at experimental campaigns.

Conversely, experimental campaigns allow advertisers to run A/B tests, conversion lift tests, brand lift tests, etc.

This means you can compare one or more campaigns to identify the best performer, measure how your ad affects brand awareness, and evaluate the results of new ad strategies compared to older ones.

These experiential campaigns require a portion of your budget and traffic to run the tests. After the testing, you will have the best-performing version based on your chosen metric. You can then implement the winning ad strategy.

A/B testing different versions of an ad, carrying out holdout tests, and conducting brand survey tests are a few examples of experimental Facebook campaigns. 

Simplified Structures for Limited Budgets

In this section, let’s discuss the strategies that simplify the structure of your Facebook ad campaigns.

Consolidated Ad sets

Earlier, advertisers created campaigns with multiple ad sets to target the audience precisely, track the return on ad spend, and identify the best-performing ad set. But now, with the introduction of the Advantage+ audience, Meta is pushing advertisers to consolidate ad sets.

That strategy starts with consolidating data. If you’re setting a budget of $25 USD on each ad set out of 4, now you can set the total at $100 USD on a single ad set.

Having single ad sets helps the meta algorithm learn faster and understand who converts faster and more accurately. It also reduces the overlapping of multiple ad sets and auctions, making reporting, scaling, and attribution simpler.

That said, there’s no thumb rule to create only one campaign and ad set. You can use multiple campaigns and ad sets. If you’re building a direct-to-offer structure, experts recommend creating two campaigns with single ad sets.

Now, let’s understand how to set them up. Let’s create two campaigns, one cold campaign with one ad set and another warm campaign with one ad set.

How to Set Up a Cold Campaign With One Ad Set?

This campaign aims to find new customers and drive the first conversion.

Here’s how to set up a cold campaign:

• Choose your campaign objective as awareness or traffic to focus on your brand awareness and drive traffic to valuable content.
• You can choose from open targeting or Advantage + audience, interest targeting, broad lookalike audiences, or interest + broad combos. Aim for targeting a wide audience.
• Create multiple creatives for videos, ad copies, headliners, etc.
• Set up auto placements, let the algorithm decide the best placements.
• Exclude warm audience to avoid overlapping.
• Remember to test and optimise the campaign. For example, run A/B tests on different targeting options to identify your best choice.

How to Set Up a Warm Campaign with One Ad Set?

• To set up a warm campaign, you should first build an audience. You can do so by engaging users with your content or website. Then, a custom audience will be created from these interactions.
• For a warm campaign, you can choose website visitors, email lists, and existing customers as your audience and consolidate them into one ad set.
• Set campaign objective as conversions. 
• Choose automatic placements and set a daily budget.

Although using single ad sets for your campaigns offers focused targeting and helps you reach your goal faster. Know when to use multiple ad sets. You can use various ad sets for:

• Distinct audiences with different bids or lifetime values, 
• to control ad placements or
• Due to Policy or legal requirements that demand separate targeting.

Create a CBO Campaign

Another simplified Facebook ad campaign structure is creating a CBO campaign with a purchase objective.

You can set the budget at the campaign level with a Campaign Budget Optimisation (CBO) strategy. This way, Facebook’s algorithm allocates the spend dynamically to the best-performing ads.

As we’ve seen earlier for consolidated ad sets, we shall create a single ad set in this strategy, too. But the targeting in this ad set is simple: just set location, age, and gender, and use automatic placements.

At the ad level, you can pick the best-performing ads from your previous campaigns, create five ads for the ad set, and run the ads. 

Monitor key metrics such as CPP, CPM, and ROAS to analyse the campaign’s performance.

Pro tip: Increase the budget gradually, add new creatives, and remove the underperforming ones. Additionally, if you’re targeting multiple locations or audiences, create separate campaigns for each objective to avoid overlap.

Sales Funnel Integration

Start with Funnel Mapping

To align Facebook ads with funnel intent, taking some time to understand your customer journey is essential.

Understanding what your customer thinks at every stage is crucial to choosing the right campaign objective, ad creative, events, budget, etc.

If a customer is in an awareness stage, you want to address ‘who you are and why a customer should buy from you.’ At this stage, set your campaign objective as reach or video views. If a customer is looking to buy, then your objective should be sales, and so on.

Therefore, it is first essential to understand the journey before creating an ad that suits funnel intent.

Match Audience Segments to User Intent

The next step is mapping audiences to intent signals.

Suppose you’re building a campaign to spread awareness about your product. Your audiences are similar to existing buyers. Therefore, create a custom audience list where you add existing customers, engaged audiences, and email lists. Add interest layers, location, age, and other factors to create lookalikes. 

Now, based on the engagement and performance of these ads, separate the viewers and create relevant ads to match each segment. For example, 30-day site visitors will receive ads that showcase social proof and features of your product, etc.

Now, you have cart views, pricing-page visits, add-to-carts, etc. The goal is to retarget this audience with dynamic ads that include data about exact SKUs, prices, etc. 

Focus on Ad Creatives

It’s time to create ads based on the funnel intent. For example, for the awareness stage, you would want to show a short video of user-generated content, for the consideration stage, a testimonial carousel, and for conversions, create scarcity with a direct CTA with ‘start free trial.’ 

 Launch ads, monitor their performance, verify events in the events manager, and add new creatives for high-performing ad sets.

Measure the Performance Based on Each Stage.

Focus on CPM and 3-second video views at the awareness stage.

Focus on landing‑page load rate and cost per engaged user for the consideration stage.

Track both front‑end CPA and seven‑ or twenty‑eight‑day ROAS at the conversion stage.

How to track these metrics?

Best Practices for Facebook ads Structure

• If you wish to test different audiences, create multiple ad sets for each segment. While doing this, ensure you maintain the rest of the settings the same to determine the most responsive audience accurately.
• Have multiple ads with variations in creative and copy. This way, the Facebook algorithm will optimise ad delivery across variations in images, video, text, or links.
• Create ads that align with your audience and business goals. Create focused ad sets with one primary audience per ad set, such as one cold interest, one lookalike, one retargeting audience, and more. 
• Do not create too many ad sets, resulting in slow learning and wasted ad spend. Keep the audience broad but targeted.
• First, the ABO strategy will be used to perform tests and understand the winners. Then, it will be moved to the CBO strategy to let the Meta algorithm allocate the budget dynamically and scale the campaign.
• Avoid making frequent changes to your ads that reset learning. Sources suggest aiming for 50 conversions per weekly ad set to exit the learning phase and stabilise.
• Remember to monitor ad performance and identify ads with lower and higher conversion rates. Pause the ads with lower conversion rates and add creative variations to see if these ads perform better.
• As discussed, the sales funnel strategy involves creating separate campaigns by funnel stage: one for prospecting, another for mid-funnel, and another for bottom-funnel. Use custom audiences and several ad copies or offers for each stage. 
• Use audience exclusions and the Audience Overlap tool to exclude existing buyers from the prospecting campaign.
• To simplify reporting, use consistent naming conventions for all your campaigns. You can follow Meta’s name template tool or create a naming convention.

Conclusion & Key Takeaways

An ideal Facebook ad campaign structure has objectives set at the campaign level, targeting/budget/placements at the ad-set level, and creative at the ad level. Additionally, mapping the structure to prospecting, retargeting, and retention is essential for scalable results. 

A few more key points to consider include:

• Create one campaign for one objective, use prospecting for top-funnel, retargeting for warm audiences, and retention to maximise Lifetime Value (LTV).
• Keep proven winning funnels evergreen; run small, controlled experimental campaigns for new creatives, audiences, or offers and promote winners into evergreen.
• Use ABO to test, then CBO to scale winners.
• Creating fewer, broader ad sets lets the algorithm learn faster. 
• Remember to exclude existing customers from prospecting to avoid wasted spend.
• Test one variable at a time. Isolate the creative or audience. Use holdouts/controls and ensure enough conversions before declaring a winner.
• Monitor funnel-specific metrics such as awareness → CPM, and 3s views; consideration → CTR, and landing-page metrics; conversion → CPA, and 7/28-day ROAS.
• Rotate creatives regularly every 2–6 weeks, watch frequency to avoid fatigue, and remove underperformers promptly.
• Use consistent naming conventions and clean structure to simplify reporting and attribution as you scale.
• Use holdouts or lift tests to measure true incremental impact rather than relying only on last-touch metrics.
