Is Facebook advertising still worthwhile in 2025?

Facebook began as a social experiment – a digital yearbook connecting university students – and quickly evolved into a global hub for sharing, connecting, and eventually marketing. Fast-forward to 2025, and it’s one of the world’s most sophisticated advertising platforms. But with ever-changing algorithms, rising ad costs, and shifting audience behaviours, many entrepreneurs are asking: Is advertising on Facebook worth it anymore?

It’s a crucial question for small businesses and startup founders with limited marketing budgets. This article breaks down the pros and cons, benchmarks effectiveness, and offers practical advice on whether Facebook advertising is still a smart play.

From social network to marketing machine

First, let’s begin with a brief history. Facebook began as a social space, but by 2007, it had opened its first ad products. By 2012, with the introduction of Facebook Ads Manager and Business Pages, it became a serious tool for marketers. The gold rush began in the mid-2010s, when entrepreneurs could reach tens of thousands of users with minimal spend.

Some of Facebook’s biggest ad success stories come from small e-commerce brands. Businesses like GoPro and Fitbit attribute early growth to their mastery of Facebook Ads, using smart targeting and creative storytelling.

However, things began to change around 2019. iOS privacy updates, algorithm shifts, and increased competition from platforms like X, TikTok and Instagram started eroding return on investment. In 2021, Apple’s iOS 14.5 update alone cost Facebook advertisers billions in lost tracking data, leading many small brands to rethink their channel mix.

Are Facebook Ads still effective in 2025?

In short: yes, but with caveats.

Facebook (or Meta, more broadly) still commands massive daily usage across its platforms, including Instagram and Messenger. Their monthly active users (MAU) have risen steadily each year, and as of early 2025, Facebook has over 3 billion monthly active users globally. That said, the platform’s organic reach has declined significantly. Paid advertising is now the only reliable way to achieve scale on Facebook, and ad costs have increased. For early-stage entrepreneurs, that means strategy matters more than ever.

If you’re asking yourself, “Are Facebook Ads effective for small businesses?”, the answer depends on your niche, audience, and how you utilise the platform’s tools. Done right, they can still be remarkably efficient, particularly for hyper-targeted campaigns or retargeting site visitors.

What are the pros and cons of Facebook advertising?

Facebook advertising has its strengths and limitations; knowing both can help you decide if it’s right for your business’s growth strategy. Here are the key advantages:

Pros

Facebook remains a powerful tool for small businesses, especially when used strategically.

• Precision targeting – Facebook still leads in behavioural and demographic targeting
• Retargeting potential – custom audiences let you remarket to site visitors, email lists, or video viewers
• Cross-platform reach – ads can run across Instagram, Messenger, and the Facebook network
• Creative flexibility – from Stories to carousels, you can experiment with formats that match your brand
• Scalable budgets – start with as little as £5 per day

While these benefits make Facebook appealing for startups, it’s important to approach it with clear goals and a testing mindset.

Cons

Even with strong potential ROI, Facebook advertising isn’t without its challenges, especially for time-pressed founders or lean teams. Here are the most common drawbacks small businesses should watch out for:

• Increased costs – cost per mille (CPMs) are a metric used to represent the cost an advertiser pays for one thousand impressions of an ad. In simpler terms, it’s the price an advertiser pays for every 1,000 times their ad is displayed to a potential customer. These costs have risen significantly, particularly in competitive niches
• Reduced attribution – tracking effectiveness has become more difficult post-2021, due to iOS updates
• Ad fatigue – users see the same types of ads repeatedly, lowering engagement over time
• Learning curve – success requires ongoing testing and optimisation
• Policy hurdles – Meta’s ad approval system can be inconsistent or unclear, especially for new brands

Are Facebook Ads effective for small businesses?

Facebook Ads can work particularly well for local businesses, e-commerce startups, or service providers with clear customer profiles. In fact, many digital-first startups still use Facebook Ads as their first acquisition channel.

The key to this success is audience targeting. Facebook allows startups to reach potential customers by age, interest, location, behaviour, or even job title. For example, a UK-based wellness brand can run ads exclusively to 25–40-year-old women in Greater London who have shown an interest in yoga and eco-friendly products.

The important consideration isn’t just whether Facebook Ads can be effective for small businesses, but rather whether you have the necessary time, creative resources, and budget to leverage the platform effectively. By assessing these factors, you can create a strategic approach that maximises the impact of your advertising efforts.

What are alternatives to Facebook advertising?

As Meta’s ad costs increase, startups are exploring alternatives. Here are some of the most popular:

Google Ads

If your product or service solves a problem people are already searching for, Google Ads could be a great fit.

• Best for – high-intent, search-driven conversions
• Pros – strong buyer intent, measurable ROI
• Cons – higher cost per click, more complex setup

Google is ideal for capturing demand rather than creating it, but expect to pay more to compete for key terms.

TikTok Ads

Perfect for visually driven, trend-sensitive brands, TikTok Ads can deliver impressive reach with the right creative. 

• Best for – visual, trend-driven awareness campaigns
• Pros – low CPMs, massive organic reach potential
• Cons – content burnout, requires fast-paced creative

If you can consistently create native-style videos that entertain, TikTok offers serious brand awareness at a low cost.

LinkedIn Ads

For B2B businesses, few platforms rival LinkedIn when it comes to targeting decision-makers and professionals.

• Best for – B2B lead generation and professional targeting
• Pros – direct access to job titles, industries, and companies
• Cons – high CPMs and cost-per-lead

Use LinkedIn if your offering is high-ticket, service-based, or requires nurturing professional relationships.

YouTube Ads

YouTube combines the power of Google’s intent data with long-form video storytelling, which is great for brands with a visual edge.

• Best for – storytelling, how-tos, and product demonstrations
• Pros – high engagement, long-form content flexibility
• Cons – requires quality video production

With the right video strategy, YouTube can build trust and drive action in ways shorter formats can’t.

Reddit Ads

Reddit’s ad platform is still maturing, but its value lies in connecting with highly engaged niche communities.

• Best for – niche products and community-driven engagement
• Pros – passionate, specific audiences
• Cons – limited scale and finicky moderation environment

If your brand solves a hyper-specific problem or serves a tight-knit audience, Reddit might be worth testing.

Many of these platforms offer strong features, but few match the granular control and scalable targeting that Facebook delivers. For entrepreneurs, combining Facebook with another channel may offer the best of both worlds.

What types of businesses benefit most from Facebook Ads?

Not every business sees the same results with Facebook Ads, but certain models consistently perform well on the platform. Facebook’s targeting capabilities and visual formats make it especially effective for brands that rely on direct engagement and clear customer intent. Here are some businesses that benefit from Facebook advertising:

• Direct-to-consumer (DTC) brands
• Local service providers (e.g., plumbers, tutors, salons)
• Subscription services
• Online course creators
• Events and workshops
• Software-as-a-Service (SaaS) companies targeting business-to-consumer (B2C)

Even B2B startups can succeed with the right content strategy, especially if they focus on lead generation through gated content or retargeting.

How to make Facebook Ads work in 2025

To make Facebook an effective part of your marketing mix, it’s essential to move beyond simply boosting posts or guessing at audiences. Success depends on using the platform’s tools strategically and making data-led decisions. Here are five tips to get better results from your Facebook ad campaigns:

1. Start with a narrow audience

Don’t cast too wide a net. Use location, interests, or job roles to define your best-fit audience.

2. Test creatives quickly

Use Meta’s A/B testing tools to compare headlines, images, and call-to-actions. Winner stays; loser gets replaced.

3. Use retargeting early

Install the Meta Pixel and start collecting data so you can retarget site visitors or email subscribers later.

4. Optimise for mobile

Most Facebook users are on mobile. Design thumb-stopping creative assets that load fast and are visually engaging.

5. Monitor and adjust

Set clear KPIs (click-through rate, cost per conversion) and adjust weekly. Don’t “set and forget” your campaigns.

Get your business set up and ready to advertise

If you’re an entrepreneur wondering if advertising on Facebook is worth it, the answer depends on your goals and execution. It’s not as cheap or easy as it once was, but for the right business model, with smart targeting, great creative assets, and continuous optimisation, you can master Facebook Ads for your small business and enjoy strong ROI.
