If you’ve logged into Meta Ads Manager lately and felt like the dashboard was speaking a different language, you aren't alone. Seriously. September 2025 has turned out to be a massive pivot point for how we handle Instagram ads. It isn’t just some minor UI tweak or a new button color. We are looking at a fundamental shift in how the algorithm decides who sees your creative and—more importantly—how much you're going to pay for those views.
Honestly, the "set it and forget it" era of social media advertising didn't just die; it was buried under a mountain of AI-driven updates this month.

The Advantage+ Takeover Is No Longer Optional
Remember when Advantage+ was just a "suggestion" from Meta? Well, as of September 2025, the training wheels are off. Meta has officially flipped the switch on Dynamic Media Default Opt-ins. Basically, if you are using third-party tools to build your ads, the system now defaults to "on" for AI-generated creative enhancements.
This means the AI is going to start automatically cropping your images, adjusting your brightness, and even generating "expanded" backgrounds to fit different aspect ratios. You have to manually opt-out now if you want to keep total control. It’s a bit aggressive, but Meta is betting that their AI can polish your assets better than a human can in half the time.
Why the "Value Rules" Change is a Big Deal
The most underrated update this month is the expansion of Value Rules to awareness and engagement campaigns. Previously, you could only tell the AI to "find me the big spenders" if you were running direct sales ads. Now, you can apply those same rules to top-of-funnel stuff.
Suppose you’re a high-end travel brand. You don't just want "views" on your Reel; you want views from people who usually book five-star suites. You can now guide the AI to prioritize those high-value individuals even when your goal is just "Brand Awareness." In early testing, this has been doubling high-value conversions for some accounts. It’s a game-changer for anyone tired of getting "cheap" traffic that never actually buys anything.

Reels Are Now 3 Minutes Long (And the Ads Followed)
Length matters again. For the longest time, we were told to keep everything under 15 seconds. "Hook them fast!" the experts screamed. But in a surprising twist, Instagram has officially pushed Reels length to 3 minutes.
This isn't just for creators. Ad formats are shifting to accommodate longer storytelling. Why? Because the "Reels Trending Ads" solution—which finally opened up to all advertisers this month—is finding that people are actually staying for the long haul if the content is "culturally relevant."
- The "Trending" Boost: These new ads use AI to slot your brand right next to whatever is going viral in specific niches like beauty, pets, or sports.
- The Results: Early data shows a 20% jump in unaided brand awareness compared to standard placements.
- The Catch: You can't just run a boring commercial. If it doesn't look like a native Reel, the algorithm will bury it.
The New Metric You Can't Ignore: Screenshots
This one is kinda wild. Adam Mosseri has been hinting at it for a while, but September 2025 is when we started seeing Screenshot Analytics roll out in the insights tab for professional accounts.
Instagram is moving away from "Likes" as a primary success signal. They’ve realized that a "Like" is low-effort. But a screenshot? That means the user wants to save your info, show it to a friend, or buy that product later. It is the ultimate "high-intent" signal. If your ads are getting screenshotted, the algorithm is going to give you a massive reach boost because it views your content as genuinely "valuable" to the user.
Threads Ads Are Finally Here (For Real)
If you’ve been waiting to jump on the Threads bandwagon, the gates are finally open. You don't even need a Threads account anymore to run ads there. You can just use your Instagram profile as the "sender" and push your existing IG posts into the Threads feed.
They’ve added 4:5 image support and carousels. It feels a bit like the early days of Instagram ads—lower competition and surprisingly high engagement. If your audience is the "chatty" type, this is where your September budget should probably be shifting.

The Brutal Reality of the Post-Purchase Feedback System
This is the "scary" part of the September update that nobody is talking about enough. Meta has tightened the screws on the Post-Purchase Feedback System.
Meta is now surveying users more aggressively after they click an ad and buy something. If your shipping is slow, or your product doesn't look like the ad, your "Customer Feedback Score" drops. In the past, this was a slap on the wrist. Now? It is directly tied to your CPMs.
Low scores = Expensive ads.
High scores = Cheaper reach.
It’s an ad-account-level penalty. One bad product launch can literally make your entire advertising strategy 30% more expensive overnight. It’s Meta’s way of killing off "drop-shipping" brands that provide a garbage customer experience.
How to Win with Instagram Ads in late 2025
So, what do you actually do with all this? Don't panic, but do pivot.
- Audit your Advantage+ settings immediately. Don't let the AI "enhance" your brand into looking like a weird AI fever dream unless you've tested it first.
- Experiment with 60-90 second Reels ads. The 15-second "goldfish attention span" rule is fading. If you have a complex product, use the extra time to actually explain the "why."
- Watch your Screenshot counts. If a specific ad is getting high screenshots, turn that creative into a permanent part of your "evergreen" campaign.
- Fix your fulfillment. You can't out-optimize a bad customer experience anymore. If your comments are full of "where is my order?", your ad costs are going to skyrocket regardless of how good your targeting is.
The landscape has shifted from "hacking the algorithm" to "proving you're a real brand." The tools are smarter, but the standards are higher. It's time to stop thinking like a media buyer and start thinking like a community builder who just happens to have a credit card on file with Meta.
Next Steps for Your Campaigns
- Check your "Account Quality" tab to see if your feedback score has been impacted by the new September thresholds.
- Duplicate your best-performing Instagram Reel and test it as a Threads placement to see how the CPC compares.
- Turn on "Value Rules" for your next engagement campaign to see if the quality of your followers improves.
