Instagram Ads Guide: What Differs From Facebook (And What Doesn't)
Instagram lives inside Meta Ads Manager but behaves differently than Facebook in several ways that matter. Here's how to set up campaigns that respect those differences.
Most operators run Instagram and Facebook as one undifferentiated thing. Same ad sets, same creative, same budget. They miss real opportunities because the placements have different audiences, different format expectations, and different conversion patterns.
The audience difference
Instagram skews younger, more visual, more mobile-only. The Feed-equivalent audience overlap with Facebook is significant but not identical. Targeting "all of Meta" via Auto Placements still gets you both, but you can't separate-out behavior afterward unless you split campaigns.
The four Instagram placements
- Instagram Feed — primary placement, scrollable feed format. Square and vertical work.
- Instagram Reels — full-screen vertical video. Highest growth placement.
- Instagram Stories — temporary 24h vertical content. Quick view, fast scroll.
- Instagram Explore — discovery feed. Lower volume but specific intent.
Each rewards different creative. Reels needs vertical UGC video. Stories needs immediate hook. Feed allows static. Explore is mostly an algorithmic placement Meta picks.
Format-specific creative
The single biggest mistake: running 1:1 square creative across Reels. It shows letterboxed, looks broken, performance tanks. For Reels and Stories, you need genuine 9:16 vertical creative.
Asset customization in Ads Manager lets you upload different files per placement. Use it. Minimum: vertical for Reels/Stories, square or portrait for Feed.
Reels-first strategy
For accounts targeting younger demographics or visual products, run Reels-only campaigns alongside Auto Placements. Lock to Reels placement, build vertical UGC creative, see if Reels-only outperforms blended.
For most accounts in 2026, Reels is the highest-volume placement on Instagram. Worth dedicating creative resources to.
FAQ
Should I run Instagram-only campaigns?
Usually no — let Auto Placements pick. Lock to Instagram only if you have IG-specific creative or want to isolate IG performance for analysis.
Does the Page need to be active organically?
Helps. Pages with active organic posting get slightly better delivery and trust signals. Empty Pages get more scrutiny.
Bottom line
Instagram lives inside Meta Ads Manager but rewards format-specific creative. Reels is the placement to invest in. Use asset customization. Don't treat IG and Facebook as the same buy — they overlap but aren't identical.
