The promise of Andromeda’s AI brain sorting through a billion users to find your customers on auto-pilot sounds quite enticing!

I couldn’t help but wonder - is this a good thing for brands?

I say this because I’ve spent 10 years tracking Meta campaign performance against actual orders, and 4 things have remained true the entire time:

  1. Meta overstates its ability to drive immediate bottom of the funnel sales
  2. Meta understates its ability to drive TOF cold traffic that leads to new customers
  3. Meta shows a lot more ROAS when you widen the attribution time window
  4. Meta’s conversion API is highly optimized for immediate sales if using the default setup

With this push to almost force advertisers to Advantage+, or turn it on behind the scenes if you don’t read the fine print, I feel it is time to use actual data, not opinion, to determine how advertisers should best use Advantage+, and when to stick to their manual guns otherwise.

I had the fearless Wicked DB team pull the data on 55,661 Meta campaigns so I could compare January through May, 2024 vs 2025, and finally get to the bottom of a few things.

Let’s dive in

 

Adoption of Advantage+

 

META Ad Spend Manual vs AdvantageASC

There is a 4% swing in budget allocated to Advantage+ over Manual Campaigns.

Insight: We will be watching this trend intensely in the summer – there are rumors that advertisers are being forced in Advantage+ with no ability to manually configure campaigns. If so, this number should jump sharply.
 

Forced Advantage+ usage means that advertisers will need advanced Meta CAPI integrations to deal with the trends below.

The Metric That Matters Most: Calculating Your True New Customer Acquisition Cost

 

META nCAC Advantage+

When using Advantage+ campaigns, the cost to acquire new customers has skyrocketed in the past 3 months.  March through May 2025 is substantially more expensive, with May 2025 vs May 2025 showing a DRAMATIC escalation in nCAC, with the average cost going from $257 to $528 per customer. Ouch.

 

META nCAC Manual Campaigns

Meta Manual campaigns are actually acquiring customers more cheaply in 2025 than they were in 2024!

 

META nCAC Manual vs Advantage+

Meta Advantage+ Campaigns were destroying manual campaign performance at the start of the year. Then things took a very dramatic turn and manual campaigns in May are crushing Advantage+ when it comes to lower nCACs.

Insight: This be the start of model degradation - or just a temporary blip.  The problem with this trend is that when new customer costs are sky high, the budget gets cut on those campaigns. This leads to less cold traffic spending, which means less traffic at the top of the funnel, which leads to future, lower performance at the bottom of the funnel.
 

Meta First Click vs Last ROAS

First let’s benchmark the first click and last ROAS on all Meta campaigns, irregardless of campaign type. I was surprised to see that on average in 2025, first click and last click ROAS are very close to each other.

All META Campaigns-2

Next we exclude Advantage+ campaigns.  The performance below shows that the manual campaigns track very closely to all campaign’s performance.  I was also surprised to see the first and last click ROAS is very similar.

META excluding Advantage+ Campaigns

Finally we look at Advantage+ campaign first and last click ROAS performance.  The last 3 months show that last click ROAS is significantly better than first click.
Additionally, 1st click ROAS plummeted in May.

ASC Campaigns

Insight: Advantage+ appears to be starting to optimize towards last click ROAS. This supports the nCAC trend above.
 

Overall, May was a dramatically worse month for performance on Meta.  If the nCAC and first click ROAS trends hold up for another month, it will be our recommendation to use Advantage+ for BOF and manual campaigns for TOF.
