Facebook Ads vs Instagram Ads: What’s the Difference?

If you're planning to advertise your business online, you may be wondering: Should I run Facebook Ads or Instagram Ads?

The good news is that you don't necessarily have to choose between them.

Facebook and Instagram are both owned by Meta, and businesses can manage advertising across both platforms through Meta's advertising system. However, the platforms have different audiences, content styles, and user behaviours.

Understanding these differences can help you decide where your ads should appear and how your advertising strategy should be structured.

Facebook Ads vs Instagram Ads: What's the Difference?

The biggest difference is where your advertisement is shown and how people interact with content on each platform.

Facebook is widely used for a broad range of content, including business pages, groups, videos, Marketplace, news-style content and community discussions.

Instagram is more visually focused, with users spending significant time interacting with photos, videos, Stories and Reels.

However, the advertising system can allow businesses to advertise on both platforms from the same Meta Ads setup.

So instead of thinking only about Facebook vs Instagram, it's often more useful to think about:

Which placement and audience are most suitable for my campaign objective?

How Facebook and Instagram Ads Work

Meta allows advertisers to create campaigns that can potentially reach people across Facebook and Instagram.

Depending on your campaign setup, ads may appear in placements such as:

• Facebook Feed

• Instagram Feed

• Facebook Stories

• Instagram Stories

• Facebook Reels

• Instagram Reels

• Other available Meta placements

This means you don't necessarily need completely separate campaigns for Facebook and Instagram.

You can test different placements and use campaign performance data to understand where your ads are generating useful results.

Facebook Ads: When Can They Be Useful?

Facebook can be particularly useful for businesses that want to reach people through a wide variety of content formats and communities.

For example, Facebook advertising can be used by:

• Local businesses

• E-commerce businesses

• Service providers

• Real estate businesses

• Educational businesses

• B2B companies

• Events and organisations

Facebook can also be useful when your target customers actively use Facebook groups, business pages or other Facebook features.

Example

Imagine a Lagos-based business selling office furniture.

The business could create an advertisement showing different office desk designs and direct interested people to WhatsApp, a website or a lead form.

The goal isn't simply to get Facebook likes.

The campaign should be designed around the business objective, such as generating enquiries or leads.

Instagram Ads: When Can They Be Useful?

Instagram is strongly focused on visual content, making it a natural environment for businesses that can communicate their value through images and short-form videos.

Instagram advertising can be useful for businesses such as:

• Fashion brands

• Beauty businesses

• Restaurants

• Travel brands

• Fitness businesses

• Skincare brands

• Lifestyle businesses

• E-commerce brands

For these businesses, high-quality visuals can make it easier to demonstrate products or communicate a brand's personality.

Example

A skincare brand could create a short video showing how its product is used.

Instead of simply writing:

“Buy our skincare product.”

The brand could demonstrate the product, explain its benefits and give viewers a clear next step.

The advertisement can then be tested across relevant placements.

Facebook vs Instagram: Audience Differences

One important consideration is your target audience.

Different groups of people may use Facebook and Instagram differently.

For example, a business targeting young adults with visually appealing products may find Instagram placements useful.

Another business targeting a broader demographic may find Facebook placements relevant.

However, you shouldn't assume that your target customers are automatically on one platform.

Your advertising data should help you understand where your audience responds.

Creative Differences Between Facebook and Instagram

Although the same advertising system can be used, the creative approach may need to change depending on placement.

Facebook

Facebook users may encounter advertisements alongside many different types of content.

Your creative should therefore communicate the important message quickly.

Useful Facebook ad formats can include:

• Images

• Videos

• Carousels

• Lead forms

• Product-focused advertisements

Instagram

Instagram is heavily visual.

Your creative should be designed with visual attention in mind.

Useful formats can include:

• Reels

• Stories

• Feed images

• Short videos

• Carousels

A creative designed specifically for Instagram Stories, for example, may not look as effective when simply copied into another placement.

Should You Advertise on Facebook or Instagram?

There isn't one universal answer.

The right choice depends on factors such as:

• Your target audience

• Your campaign objective

• Your product or service

• Your creative format

• Your budget

• Your previous advertising data

• Where your customers actually respond

For many businesses, testing both platforms can provide more useful information than choosing one based purely on assumptions.

Don't Choose a Platform Based Only on Popularity

One common mistake advertisers make is choosing a platform because they personally use it.

For example:

“I use Instagram every day, so my customers must be on Instagram.”

That isn't necessarily true.

Your personal behaviour isn't the same as your customers' behaviour.

Instead, consider:

Who is my customer?

What problem are they trying to solve?

What type of content do they respond to?

Where can I realistically reach them?

These questions are more useful when developing an advertising strategy.

Facebook Ads vs Instagram Ads for Small Businesses

Small businesses often have limited advertising budgets.

That makes testing and measurement particularly important.

Instead of immediately spending a large amount of money, a business can start with a controlled campaign, monitor performance and learn from the results.

For example, a business could test:

• Different audiences

• Different creatives

• Different placements

• Different offers

• Different calls to action

The goal is to discover what produces meaningful results for the specific business.

What If Instagram Gets More Likes but Facebook Gets More Leads?

This is where metrics become important.

Imagine you run an advertising campaign and get:

Instagram: 100 likes

Facebook: 20 leads

Which result matters more?

It depends on your campaign objective.

If your goal is lead generation, the number of qualified leads may be more important than the number of likes.

If your goal is sales, you may need to look at purchases and revenue.

This is why you should avoid judging advertising performance based on likes alone.

How to Decide Where Your Ads Should Appear

Use this simple process:

Step 1: Identify Your Objective

What are you trying to achieve?

For example:

• Website traffic

• Leads

• Sales

• Brand awareness

• Engagement

• App promotion

Step 2: Understand Your Audience

Identify:

• Age range

• Location

• Interests

• Behaviours

• Customer needs

• Buying habits

Step 3: Consider Your Creative

Ask whether your content works better as:

• A static image

• A carousel

• A short video

• A Reel

• A Story

Step 4: Test

Don't rely entirely on assumptions.

Test relevant placements and monitor the results.

Step 5: Optimise

Once enough data is available, identify where you're getting useful results and adjust your strategy accordingly.

Facebook Ads vs Instagram Ads: Common Mistakes

1. Creating one creative for every placement

A square image may not be ideal for every placement.

Consider creating different versions for different formats.

2. Focusing only on likes

Likes can be useful engagement signals, but they don't necessarily mean you're generating customers.

3. Ignoring the offer

Even a well-designed advertisement may struggle if the offer doesn't give people a strong reason to take action.

4. Targeting everyone

A large audience isn't automatically a good audience.

Your targeting should have a logical connection to your potential customers.

5. Changing campaigns too frequently

Constantly changing your audience, creative or budget can make it difficult to understand what's actually working.
