How to Advertise on Instagram (2026): Complete Guide

Instagram is one of the most powerful advertising platforms in the world — and one of the most misunderstood, because so many people think of "Instagram ads" as separate from "Facebook ads." They aren’t. Instagram is part of Meta, and advertising on it runs through the same system, the same auction, and often the same campaign as Facebook. This guide explains how to advertise on Instagram in 2026: how it relates to Facebook, the placements and formats you can use (Reels, Stories, feed and more), how to set up a campaign through Meta, high-level creative specs, how to budget, and why understanding the shared auction changes how you think about the whole thing. (We use dollars here, but the logic is identical in any currency.)

Quick answer: to advertise on Instagram, you run ads through Meta Ads Manager (or, for the simplest cases, boost from a professional Instagram account). Instagram is a set of placements — Reels, Stories, feed, Explore — inside Meta’s advertising system, so you generally build one campaign and let it run across Facebook and Instagram together, or restrict placements to Instagram only. The creative, budgeting and optimisation principles are the same as Facebook because it’s the same auction; what changes is the format and the audience mindset.

Instagram and Facebook are the same system

The single most important thing to understand: Instagram ads and Facebook ads are not two platforms — they’re one. Both are Meta properties, both are managed in the same Ads Manager, and both compete in the same real-time auction for attention. When you create a campaign, Instagram simply appears as a group of placements you can include or exclude, alongside Facebook’s.

This has a practical consequence: for most advertisers, the best approach is not to build "an Instagram campaign" in isolation. You build a campaign with a goal and creative, and let Meta’s delivery decide whether each impression is cheaper and more effective on Instagram or Facebook. Because it’s the same auction, everything you already know about Facebook ad costs and lowering your CPM applies directly to Instagram too. If you want Instagram-only delivery — say your audience genuinely lives there — you simply restrict the placements. To understand what those surfaces are, see our glossary on Facebook ad placements.

Instagram placements and formats

Instagram offers several distinct placements, and each suits a different kind of creative. Knowing which is which helps you design ads that feel native rather than pasted in.

Reels

Reels is Instagram’s fastest-growing surface and, in 2026, often its cheapest reach. Full-screen vertical video that entertains or hooks in the first second performs best; polished "TV ad" style clips tend to be scrolled past. This is where native, UGC-style creative wins.

Stories

Stories are full-screen and fleeting, which makes them ideal for urgency, limited offers and casual, authentic content. Design for the format: vertical, text kept clear of the top and bottom UI, and a single clear action.

Feed and Explore

The feed still suits more considered products and longer captions, where someone might read before deciding. Explore places your ad in front of people actively discovering new things, which can be a strong prospecting surface. Letting Advantage+ placements run across all of these usually lowers your blended cost, because Meta serves each impression wherever it’s cheapest.

How to set up Instagram ads through Meta

There are two routes, and the right one depends on how much control you want.

The simple route: boosting

From a professional Instagram account you can "boost" an existing post directly in the app. It’s fast and beginner-friendly, but it gives you limited control over objectives, audiences and optimisation — fine for a quick reach push, not for serious performance.

The proper route: Meta Ads Manager

For real campaigns, use Ads Manager. The core steps mirror any Meta campaign:

1. Connect your Instagram account to your Meta Business account so ads can run under your Instagram identity.
2. Choose an objective that matches your goal — sales, leads, traffic or awareness.
3. Set audience and placements — go broad and either include Instagram within Advantage+ placements or restrict to Instagram only.
4. Set your budget and let the learning phase run.
5. Upload creative sized for the placement — vertical video for Reels and Stories, square or portrait for feed.
6. Publish and measure by cost per result, not vanity metrics.

Because the mechanics are identical to Facebook, our guide to creating a Facebook ad campaign walks through the same flow in more detail — everything there applies to Instagram.

Creative specs at a high level

You don’t need to memorise exact pixel dimensions — Meta updates them and Ads Manager warns you when something’s off — but a few principles hold steady in 2026:

• Go vertical for Reels and Stories. A 9:16 full-screen frame is non-negotiable for those placements; horizontal video wastes most of the screen.
• Use square or portrait for feed. 1:1 or 4:5 takes up more screen than landscape and stops the scroll better.
• Design for sound-off, reward sound-on. Many people watch muted, so use captions and on-screen text — but make sound a bonus, not a requirement.
• Keep text clear of the edges on Stories and Reels so the interface doesn’t cover it.
• Hook in the first second. Instagram is a fast-scroll environment; the opening frame decides everything.

The deeper creative playbook — hooks, formats, what makes people stop — is in our guide to Facebook ad creative tips, and the words that go with them in our guide to writing ad copy that converts. Both apply to Instagram unchanged.

Targeting on Instagram

Targeting works exactly as it does on Facebook, because it’s the same audience system. In 2026, broad targeting plus strong creative usually beats tightly stacked interests — Meta’s delivery is very good at finding the right people when you give it room and a good ad. Keep a custom audience of your visitors and customers for retargeting, which is almost always your most efficient spend, and use lookalikes to prospect from your best buyers. The full approach is in our guide to Facebook ad targeting — none of it changes just because the ad shows on Instagram.

Budgeting for Instagram ads

Since Instagram runs in the same auction as Facebook, budgeting follows the same logic and there’s no separate "Instagram price." Costs vary by country, niche, season and creative quality, just as they do on Facebook. Work your budget backwards from your goal — target orders divided by conversion rate gives the clicks you need, and clicks times cost per click gives the budget — and our ad budget calculator does that math in seconds.

For a small business, a sensible starting point is the same $15–$50 a day per campaign that works on Facebook: enough to exit the learning phase and see whether the sales process works, without risking much. Judge results by cost per result and ROAS against your break-even — one divided by your gross margin — using our ROAS calculator, and raise budget only once the ads are profitable. For the full picture, see how much Facebook (and Instagram) ads cost.

Why the shared auction matters

Understanding that Instagram and Facebook share one auction changes how you should act. It means you generally shouldn’t silo them: letting one campaign run across both, with Advantage+ placements, lets Meta buy the cheapest effective impression wherever it is — often lowering your blended cost. It means your creative has to work in multiple formats, since the same ad may appear in a Facebook feed and an Instagram Reel. And it means all your existing Meta knowledge transfers directly: the same levers that lower your cost per click and the same best practices that make Facebook campaigns work make Instagram campaigns work too. There is no separate skill to learn — just a new set of formats to design for.

Frequently asked questions

How do I advertise on Instagram?

Run ads through Meta Ads Manager (or boost a post from a professional Instagram account for the simplest cases). Instagram is a set of placements — Reels, Stories, feed, Explore — inside Meta’s advertising system, so you build a campaign with an objective and creative and either include Instagram within Advantage+ placements or restrict delivery to Instagram only.

Are Instagram ads different from Facebook ads?

Not fundamentally — they’re the same system, the same Ads Manager and the same auction. Instagram simply appears as placements you can include or exclude. What differs is the format and mindset: Instagram leans heavily on full-screen vertical video (Reels, Stories), so your creative should be designed for those surfaces even though the mechanics are identical.

How much do Instagram ads cost?

There’s no separate Instagram price — it runs in the same auction as Facebook, so cost depends on country, niche, season and creative quality. A small business can start at roughly $15–$50 a day per campaign. Work your exact budget backwards from your goal using target orders, conversion rate and cost per click, and judge results by cost per result and ROAS.

Should I run Instagram-only campaigns?

Usually not. Because Instagram and Facebook share one auction, letting a single campaign run across both with Advantage+ placements lets Meta buy the cheapest effective impression wherever it is, often lowering your blended cost. Restrict to Instagram only when your audience genuinely lives there and you have a specific reason to exclude Facebook.

What creative works best on Instagram?

Native, full-screen vertical video for Reels and Stories, and square or portrait for the feed. Hook in the first second, design for sound-off with captions, keep text clear of the interface edges, and favour authentic, UGC-style clips over polished "TV ad" production. The same hooks and copy principles that work on Facebook apply here unchanged.
