You have a small budget for ads and you want to spend it in the right place. One person tells you Instagram is where the customers are. Another says Facebook is cheaper and works better for local businesses. So you either pick one at random or never start. The good news is that this is less of an either-or choice than it looks, because both run on the same system. What matters is knowing how they differ and letting real results decide.
They are one ad system, not two
Facebook and Instagram are both owned by Meta, and ads for both are created in the same place: Meta Ads Manager. When you create a campaign, you choose your goal, your audience, your budget and your ad, and then choose where it can appear. These places are called placements, and they include:
- Facebook: Feed, Stories, Reels, Marketplace, search results and others
- Instagram: Feed, Stories, Reels, Explore and others
- Other Meta placements, such as Messenger and the Audience Network of partner apps
So the real question is not "Instagram or Facebook?" It is "should I let Meta show my ad everywhere, or limit it to certain places?" Meta's default option, called Advantage+ placements, lets its system spread your budget across placements where it expects the best results for your goal. You can also choose manual placements and pick exactly where your ads appear.
How the two platforms feel different
Even though the ads come from one system, people use the two apps differently, and that affects what works.
- Instagram is visual first. People scroll through photos and short videos. Ads need strong images or video that look natural in the feed, Stories or Reels.
- Facebook is broader. People read posts, join local groups, browse Marketplace and follow local pages. Ads with a bit more text, offers and practical details often fit well there.
- Audiences overlap but are not identical. In general, Instagram leans younger and Facebook has a wider age range, including many older adults. Your own customers matter more than general trends, so check who actually buys from you.
Which is better for your type of business
There is no rule that works for everyone, but these patterns are a reasonable starting point:
- Visual businesses such as salons, restaurants, cafes, boutiques, event decorators, photographers and fitness studios often do well on Instagram, because the product is something people want to look at.
- Home services and local trades such as plumbers, roofers, cleaners and landscapers often get good leads from Facebook, where many homeowners are active and lead forms are easy to use.
- Businesses with a broad local audience, such as dentists, gyms or clinics, usually benefit from running on both and letting the results show the split.
- Businesses selling to older customers will often find more of them on Facebook.
Treat these as starting guesses, not facts about your business. The only reliable answer comes from testing with your own ads in your own area.
Making ads that work on both
If you run on both platforms, prepare your ad so it looks right everywhere it can appear:
- Use the right shapes. Square (1:1) or tall (4:5) images and videos suit feeds. Full screen vertical (9:16) suits Stories and Reels. Ads Manager lets you upload different versions for different placements.
- Keep important text away from the edges of vertical videos, where app buttons and captions cover it.
- Show real work. Real photos of your team, your shop and your results usually look more trustworthy than stock images.
- Make the first seconds count. In video, show the product or result right away.
- Add captions to videos, because many people watch with the sound off.
- Preview every placement in Ads Manager before publishing, and fix anything that looks cut off.
How to split a small budget
With a small budget, splitting money into many separate campaigns usually spreads it too thin. Meta's system learns from results, and Meta says an ad set generally needs around 50 results in a week to leave its learning phase. A simple approach:
- Start with one campaign aimed at the goal you care about, such as leads or messages, with Advantage+ placements turned on.
- Let it run for a couple of weeks without big daily changes.
- Check the breakdown by placement in Ads Manager to see where your leads actually came from, and what each one cost.
- Then decide. If one platform brings much better leads, you can shift towards it with manual placements. If both work, leave it.
Remember there can be two costs: the ad budget you pay Meta, and a management fee if you hire help. Our guide to Facebook ads management cost explains both.
When it makes sense to use only one
Running on both is a good default, but there are times when limiting your ads to one platform is the better choice:
- Your ad only exists in one shape. If you only have a vertical Reel, it may look best on Instagram and Facebook Reels and Stories. If you only have a text-heavy offer image, the Facebook feed may suit it better.
- Your results clearly say so. After a fair test, if one platform brings leads that turn into customers and the other brings mostly time wasters, move the budget.
- You want to use Marketplace or local groups. These are Facebook features, so people who buy that way are on Facebook.
- Your customers tell you. Ask new customers where they saw you. Their answers are often the clearest guide you will get.
What to measure
Comparing platforms on likes or cheap clicks leads to bad decisions. Compare them on what matters:
- Cost per lead or message from each platform
- Lead quality: how many were real, local people ready to buy
- Customers won and what they were worth
Sometimes one platform gives cheaper leads, but the other gives leads that turn into more customers. Track all the way to sales if you can, even with a simple spreadsheet.
Common mistakes
- Choosing a platform based on personal habits instead of customer results
- Using one landscape image everywhere, so it looks wrong in Stories and Reels
- Running separate tiny campaigns for each platform that never leave the learning phase
- Boosting posts for likes and expecting enquiries
- Judging results after two or three days
- Replying slowly to messages and leads from either app
