If you woke up in October 2025 and felt like your Ads Manager was gaslighting you, you weren’t alone. Meta didn't just move a few buttons around. They fundamentally rewired how the "brain" of the platform handles your money. Honestly, the old way of micro-managing every single interest group is dead, and the October updates basically nailed the coffin shut.
We saw the rollout of the Andromeda backend infrastructure go full scale. This isn't just a cool-sounding codename. It’s a massive shift in how Meta retrieves and serves ads. Instead of the algorithm spending days "learning" your audience, Andromeda uses a much faster relevance scoring system to match your creative to a user in milliseconds. It’s why you might have noticed the "Learning Phase" practically disappearing or finishing in half the time it used to.
The Death of Manual Control in Meta Advertising Update October 2025
The biggest shocker for most was the "Advantage+ Leads" expansion. Before this, we had Advantage+ for Shopping, but now Meta is pushing everyone toward fully automated Lead Generation. You basically give them a URL, some creative assets, and a budget, then step back.
It feels risky. I get it.
But the data coming out of these October tests is hard to argue with. Many agencies reported a 20% to 25% drop in Cost Per Lead (CPL) when they finally stopped fighting the machine. Meta is actively hiding manual setup options now. They want you in the "Simplified" view. It’s not just a suggestion anymore; it’s the default operating system.
Why Your "Winning" Ads Might Be Killing Your Funnel
Here is where it gets weird. With the new Campaign Consolidation logic introduced this month, Meta is encouraging you to put your cold, warm, and hot audiences all into one single ad set.
Wait, what?

Yes. The AI now decides which ad to show based on where the user is in their journey. You might have one ad getting a $5 lead and another getting a $40 lead in the same campaign. Old-school buyers would kill that $40 ad instantly. Don't do that. Meta’s new reporting shows that the $40 ad is often the "opener"—the one doing the heavy lifting to warm people up—so that the $5 ad can close them later. If you kill the "expensive" one, the cheap one usually dies 48 hours later.
The "Meta AI" Listening Update
This was the one that sparked the most Reddit threads. Starting in October, Meta began notifying users that their interactions with Meta AI (the chatbot in your DMs and search bar) would now influence ad targeting. If you’re chatting with the AI about planning a hiking trip to the Alps, expect to see boots and trekking poles in your feed by dinner.
For advertisers, this is a goldmine. It’s a "closed-loop" data source. Since privacy laws like the DMA in Europe are making third-party tracking harder, Meta is just building its own first-party data through these AI conversations. It’s smart, but it definitely feels a bit "Big Brother-ish" for the average user.
Threads Ads are Finally Real
We’ve been waiting for this since 2023, but October 2025 was the official wide-release of Threads Feed placements in the Marketing API. You can now toggle Threads as a placement just like Instagram Stories or Reels.
But there’s a catch.
Threads users are picky. If you try to run a "BUY NOW 50% OFF" graphic with a giant red border, you’re going to get roasted in the comments. The most successful ads on Threads right now are text-heavy or look like native "takes" on trending topics. Meta also increased the maximum height for video on Threads to 4:5, so you don't have to worry about weird 1:1 square cropping anymore.
How to Handle the New "Opportunity Score"
You’ve probably seen that 0-100 score in your account. Meta calls it the "Campaign Health Score" or "Opportunity Score." It’s basically their way of grading how well you’re following their rules.
- High Score: You’re using Advantage+ placements, broad targeting, and automated budgets.
- Low Score: You’re still using manual interest targeting and excluding specific zip codes.
Does a 100/100 score mean you’ll be rich? No. But Meta has confirmed that accounts with higher scores often get lower CPMs (Cost Per Mille). The algorithm rewards you for making its job easier. If you fight the automation, you pay a "manual control tax" in the form of higher ad costs.
What Most People Get Wrong About October’s Update
The biggest misconception is that "Interest Targeting is gone." It isn't. But it's becoming a "suggestion" rather than a hard rule. Even if you select "Golf," Meta's AI will still show your ad to people who have never touched a club if the data says they are likely to buy your product.

You have to shift your focus. Your job isn't to find the audience anymore; your job is to call out the audience through your creative. The algorithm reads the text in your video, the copy in your headline, and even the objects in your images to figure out who to show the ad to.
Actionable Next Steps for Your Campaigns
If your performance took a dip after the October changes, here is exactly what you need to do to fix it:
1. Embrace the 3:2:2 Testing Method
Stop running one ad at a time. Use Dynamic Creative. Upload 3 videos/images, 2 headlines, and 2 primary texts into one ad set. Let the Andromeda engine find the winning combination for you. It’s much faster than manual A/B testing now.
2. Audit Your Lead Forms
Meta updated the terms for Lead Ads this month. You now have to be much more explicit about how you use data. If you’re in the EU, you can’t use lead form data for a general newsletter unless you have a specific, separate checkbox for it. Check your forms before they get flagged.

3. Switch to Broad (For Real This Time)
If you are still using 10 different interest-based ad sets, consolidate them. Move into one "Broad" ad set with zero interest targeting. Set the age, gender, and location, then let the creative do the heavy lifting.
4. Test Threads Placements
Create a specific "native-style" ad for Threads. Keep it conversational. Mention a hot take or ask a question. This placement is currently cheaper than Instagram Reels because there’s less competition, but that won't last long as we head toward the 2026 budget season.
The Meta advertising update October 2025 basically marks the end of the "media buyer" as a button-pusher and the birth of the "creative strategist." If you can’t make a good video, no amount of algorithm hacking is going to save your ROAS. Trust the machine to handle the delivery, but don't trust it to tell your story.
