Been running the same carousel ads for a client since January. Always pulled about a 3.5x ROAS. This past month, it's tanked to 1.8x. Same creative, same targeting, same budget. Tried tweaking the copy, changing the CTA, nothing moves the needle. Feels like platforms are pushing their own commerce features harder, or maybe just squeezing advertisers before a bigger shift. Makes you wonder what the point of building all this inventory is if you can't reliably sell against it.
