Are ASC+ campaigns fading in their automation, resulting in low conversion rates?
This isnโt Metaโs fault – Itโs youโฆ!
Advantage Shopping Campaigns (ASC+) need clean first-party data signals to optimize conversions effectively.
Meta says,
First-party data (1PD) helps Meta Andromeda, a new updated algorithm, to learn better by providing more detailed signals. This results in improved performance, smarter ad targeting, and higher conversion rates. If youโre trying to improve conversions in ASC+ campaigns using first-party data.
Keep reading to know why ASC+ campaigns need strong signals, the one-stop solution, along with real-world case studies to prove Metaโs above statement. (Towards the end, there is a step-by-step playbook to knock your ASC+). Letโs dive in.

Why ASC+ Campaigns Need Strong First-Party Data Signals?
Metaโs Advantage+ Shopping Campaigns have gone full AI & machine learning, and thatโs both a blessing and a curse.
Metaโs Andromeda engine powers ASC+ with sequential learning, which means it studies each user action in the order it happens, like (every click, add-to-cart, and purchase) helps the system learn whoโs most likely to convert next.
But if your signals are missing or broken, Andromeda canโt connect the dots. Itโs like handing Meta half the puzzle and expecting a full picture.
Thatโs why clean first-party data matters. It helps ASC+ learn faster, predict smarter, and scale your campaigns without wasting ad spend
It learns from your conversion signals like (Add to Cart, Purchase, and Click) to figure out whoโs most likely to buy next. The better the signals, the faster it learns
But hereโs the problem: not all signals are created equal.
Strong identifiers like (email, phone number, browser ID, and click ID) give Metaโs algorithm something real to focus on. Weak signals like name, gender, or location donโt make much difference.
So when you feed ASC+ weak or incomplete data, it keeps spending but doesnโt really learn.
And thatโs the silent killer: your ads still run, but your ROAS is flatlining. Let’s look into the core problem of the ASC+ campaign
What are the Common Problems: Broken Attribution & Signal Dilution?
Have you ever wondered why the ASC+ campaign feels like they are running blind?
When your conversion data is missing or messy, Meta canโt see the full picture. It doesnโt know who is most likely to buy, which audience to target, or which products to promote. This causes broken attribution, weak signals, and your ROAS stays flat.
If the signal you send is broken, Meta canโt learn properly, and feeding trashed data makes the learning algorithm work like garbage.
The core problem pinpoints two major issues: one, broken attribution, and two, signal dilution.
Let me break it down in detail about them.
Broken Attribution
Attribution helps Meta to connect the dots from someone seeing your ads to actually buying your product. But after the privacy updates like iOS 14+ and several privacy regulation policies, the connections are not as strong as before.
This happens when someone clicks a paid ad, but later searches for your brand organically and makes a purchase, but Meta doesnโt know it happened.
When the attribution breaks, Meta canโt see the conversions. You might think your ads arenโt working, even if they are.
Signal Dilution
Even when signals reach Meta, they are often mixed up or unclear.
Pixels, analytics tools, and CRMs can send confusing or incomplete data, so Meta doesnโt always know whatโs right.
For example, a customer adds a product to their cart, but your tracking tools send slightly different information. Meta gets mixed signals and may target the wrong people or actions.
That too many low-quality or duplicate events confuse the algorithm. It ends up in surface-level engagement like (add to cart) instead of a real purchase.
When attribution breaks and the signals weaken, Metaโs automated algorithms lose clarity. ASC+ starts spending without learning – budget burns, ROAS drops. By sending bad signals, campaigns stop improving.
How does the ASC+ Optimization Framework, Powered by First-Party Data?
Metaโs advantage+ shopping campaigns are data-driven machine learning algorithms that give the results based on what you train them with.
When you give first-party data to Meta, it will be beneficial to you.
Wondering why first-party data? The logic is simple – โPeople who already interacted with your brand are the high-intent audience and are most likely to convert, compared to others.โ
First-party data also provides relevant audience signals to Facebook to understand who the right audience is. It drives the algorithms to expand their audience network in finding relevant target audiences.
Train Metaโs ASC with First-party Data
Swiftly sync all your stored first-party audience data with Meta with just a click from CustomerLabs 1PD Ops. Do not forget to enable the โActivate UTM parameters for custom audience types for Advantage+ shopping campaigns.โ
Doing this sends Meta two signals โ
1. All your first-party data audience segments will be synced to Meta as a custom audience.
Metaโs algorithms will learn from the audience signals of this first-party data and train themselves on these data signals to find new prospects.
2. Your UTM parameters at the ad account level for the ASC are set as โnew_audienceโ for new customer value, and โfirst_party_audienceโ for existing customer audiences who have interacted with your brand.
Having these UTM parameters will help in reporting and attributing the purchases correctly to new and existing first-party audiences separately.
Campaign Level Settings for Improving Conversions in ASC.
Once the audience is synced, start setting up the ASC campaign.
At the budget & schedule stage, cap the existing customer budget at 20%. This means 20% of your ad budget is spent on the middle of the funnel audience (first-party audience).
The next steps are similar to the standard campaign setup.
Use attractive ad creatives, compelling ad copies, and relevant landing pages in the subsequent stages.
Note: Thereโs no Ad and Ad set level for ASC. There are only two levels โ campaign level and one level after that to add the ad creatives, landing page URL, etc.
We donโt need more theory; we need action. Hereโs a brand that put these strategies into action and got real results.
Real-World Case Study: How MNMLST Improved ASC+ Conversions Using First-Party Data
Sometimes you need to see it to believe it.
MNMLST, a high-value luxury product brand, faced the same problem. The ad campaigns were underperforming because the standard purchase events werenโt giving Meta the right signals.
What are the Challenges the Brand faced?
MNMLST struggled with Shopifyโs default CAPI because it gave weak signals. This made Metaโs algorithm less able to find high-value customers, which caused their ROAS to stay flat and ad spend to be less efficient.
What are the Actions taken by IPD Ops?
To fix these issues, MNMLST used CustomerLabsโ Advanced CAPI solution, which allowed them to:
- Custom Conversion Events track and segment actions by Average Order Value (AOV), product type, and customer group (like gender), so campaigns could be more precise.
- Enhanced Event Match Quality (EMQ) boosts the quality of signals by capturing more user actions and details, helping Meta better understand whoโs engaging.
- Guide Metaโs algorithm with business-specific goals so it learns faster and optimizes campaigns for higher ROAS.
The Results they got
- Revenue growth increased to +117% overall.
- By retargeting, improve the conversion of high-intent shoppers, leading to more precise ad spend.
- Post-Purchase journeys result in more relevant follow-up campaigns that drive upsells and repeat purchases.
By training Metaโs algorithm with precise and high-quality signals, MNMLST optimized their advantage shopping campaigns the way Meta wants them. And they got the results they wanted, which increased sales, repeat orders, and upsells
This is proof that first-party data is a necessity, and it is the fuel that powers Metaโs AI algorithms to benefit from ASC+ campaigns.

Let’s look at a real number that shows the benchmarks.
Why are Industry Benchmarks important for ASC+ Campaigns?
Knowing the average numbers in your industry helps you see how your campaigns are doing and where you can do better.
Hereโs a quick look at the main stats for Retail, Apparel, and D2C brands.
| Industry | Avg. Conversion Rate (CR) | Avg. CTR | Avg. CPC |
| Retail | 2.81% | 2.69% | $1.09 |
| Apparel | 2.15% | 2.15% | $1.01 |
| D2C | 2.81% | 2.69% | $1.09 |
What this means:
- CR (Conversion Rate): Out of 100 people who visit your site, 2โ3 usually buy something.
- CTR (Click-Through Rate): About 2โ3 people out of 100 who see your ad click on it.
- CPC (Cost Per Click): Each click costs around $1.
If your numbers are lower than these, your campaigns might need better targeting, ads, or tracking. Basically, it needs better signals to help ASC+ optimize.
Letโs look into the step-by-step playbook for improving ASC+ conversions.
Step-by-Step Playbook to Improve ASC+ Conversions
Step-by-Step Playbook to Improve Conversions in ASC+ Using First-Party Data. Follow these steps to make sure Meta has the right signals to optimize them properly.
A. Audit Your Data Signals
- Before you start, take a close look at the data you feed Meta.
- Make sure nothing is missing, like conversion events, and check that you donโt have duplicate or messy signals.
- Also, see if there are any gaps in tracking across devices or platforms.
Think of it like cleaning your desk. Meta can only work well if the data you provide is clear and organized.
B. Sync Server-Side 1P Data
- The best way to give Meta an accurate signal is by sending first-party data directly from your own server, not through a browser.
- Connect your website or CRM to share real-time actions like purchases or sign-ups, along with key details such as product type, transaction value, and customer profile.
- This process, known as server-side tracking, is a privacy-safe way to deliver reliable signals to Meta without relying on cookies or front-end scripts.
- It helps brands maintain data accuracy, improve event delivery speed, and strengthen attribution even after iOS and browser privacy updates.
- That means ASC+ learns from real customer actions instead of incomplete or missing data.
C. Set Up Event Quality Monitoring
- Once your signals are flowing to Meta, the next step is event quality monitoring.
- Making sure every action you send (purchase, add to cart, signup, etc.) is clean, accurate, and complete.
- Send your own customer data directly from your website or CRM to Meta.
- Make sure it includes signals like product purchased, order value, and customer type (new buyer, repeat purchaser, or high-value user)
- Metaโs ASC+ algorithm learns from the quality of your events. If the signals are incomplete, duplicated, or delayed, Meta canโt accurately find your most valuable customers.
- When your event data is accurate, ASC+ can quickly figure out whoโs likely to buy and help your ads reach the right people.
D. Optimize Campaign Structure
- Segment by value: Split your audiences into High AOV buyers and Low AOV buyers (or casual shoppers). This lets ASC+ focus on the people who drive the most revenue.
- Clear naming conventions: Give your campaigns and ad sets simple, descriptive names so you can track performance easily.
- Test ads and placements: Experiment with creatives and placements, but keep the structure organized to avoid confusing the algorithm.
A strong, organized setup ensures ASC+ learns efficiently and optimizes for the right audience, maximizing your conversions.
