Facebook and Instagram run on the same Meta Ads platform, so the question isn't really which platform, it's which placement fits your audience and your creative. Instagram skews younger and more visual; Facebook still reaches an older, broader audience with real purchasing power in many categories.
They're the same campaign, different placements
When you set up a Meta Ads campaign, Facebook and Instagram are placement options inside the same ad set, not separate platforms with separate setups. You can run both together, or select just one, using the exact same creative, budget, and tracking.
Who's actually on each one
Instagram tends to skew younger, more visual, and more engaged with Stories and Reels. Facebook still holds a broader, often older audience, including decision-makers in B2B and service categories who spend real time in Facebook Groups and Marketplace. Neither is objectively better, they just reach different slices of the same market. Instagram's user base skews younger and more visual-first, while Facebook still holds a meaningfully older audience with higher average purchasing power in several categories, which is why the same budget split 50/50 doesn't perform the same for a med spa targeting 25-year-olds as it does for a home services business targeting homeowners in their 40s and 50s.
Which fits which kind of business
Visual, lifestyle-driven categories (restaurants, boutiques, real estate, beauty) usually get more traction on Instagram. Service businesses, local businesses with a broader-age customer base, and anything selling through community trust often perform better weighted toward Facebook.
The creative usually needs to change too
A vertical, fast-paced Reel built for Instagram often looks out of place as a Facebook feed ad, and a longer, more explanatory Facebook video can feel slow on Instagram. Running one identical creative across both placements without adjusting format is a common reason results look mixed.
How to actually decide
If budget is tight, start with automatic placements and let Meta's delivery data show which platform is actually converting before manually restricting anything. Once you have two to three weeks of data, split budget toward whichever placement is producing cheaper results for your specific offer.
Frequently asked questions
Yes, it's the default setup in Meta Ads: one ad set can deliver on both platforms at once. The platform automatically decides how much budget to send to each based on where it's converting better, unless you manually restrict it.
It depends on the category and how competitive the ad space on each is at that moment. There's no fixed rule that one is always more expensive; it varies by industry, season, and creative quality.
Yes, you need a professional Instagram account connected to your Facebook page and your Ads Manager to run campaigns there, even though the ad is managed from the same Meta Ads platform.
In most accounts, yes, because Meta is actively prioritizing short-form video on both platforms right now. But a poorly made Reel underperforms a well-thought-out photo; the format doesn't replace a good creative.
