How Meta Advertisers Are Restructuring for Post-Andromeda

Performance marketers and ecommerce operators are increasingly discussing how to restructure Meta ad campaigns following changes associated with the platform’s so-called “Post-Andromeda” algorithm behavior.

The discussion centers around a common issue in Meta advertising: older campaign structures that previously scaled efficiently are reportedly becoming less stable under newer optimization systems. Advertisers say they are seeing inconsistent conversion performance, unstable learning phases, weaker targeting signals, and rising acquisition costs when increasing budgets.

As a result, marketers are experimenting with more simplified campaign setups designed to help Meta’s algorithm optimize more predictably while maintaining stronger conversion data signals.

A recurring strategy shared by advertisers involves running broad-targeting CBO campaigns with limited ad sets and controlled creative testing.

“I also do dropshipping. Right now I’m doing around $2–3k per day. What works for me is running a CBO campaign with Advantage+ and broad targeting. I start with ad set 1 and use three different variations of the same ad. Then I add ad set 2 with a new ad, again using three different variations of that same ad. giving meta more options to choose.”

“Start with one CBO campaign one ad set broad targeting and a small set of strong creatives then scale only after consistent purchase data trains the pixel.”

Another advertiser emphasized that budget allocation and creative fatigue management have become increasingly important in competitive markets.

“All you need is this.

Don’t listen to what people say because they genuinely don’t know. Unless you’ve tested around 100,000 ads, you can’t rely on creatives (even though it works) because it changes over time.

Especially for brands/stores, run 1 CBO campaign with 1 ad set, but because you’re dealing with a competitive market, you’ll need your budget to allocate with the creatives so that you’re ads don’t fatigue.”
