Social Media Advertising: What it Is, What it Costs, and How to Make it Work

Most businesses think social media advertising means hitting the boost button under a post that did well. That button is quietly the biggest waster of small-business ad budget in Australia. It hands your money to the platform, asks it to chase cheap likes, and calls the likes a result.

Real social media advertising is something else entirely. It’s a paid demand engine: structured campaigns that put a specific offer in front of a specific person and move them to buy, on platforms like Meta, TikTok, Pinterest, LinkedIn and Reddit. Same platforms as the boost button, completely different outcome.

This guide covers what social media advertising actually is, the platforms and who they suit, what it costs, whether it really works, and how to start without setting fire to your budget.

What social media advertising actually is

Social media advertising is paying to place ads on social platforms, with control over who sees them, what they see, and what you want them to do. It sits alongside search advertising as one half of paid media, and the two do different jobs. Search catches people already looking for you. Social puts you in front of people before they’re looking, based on who they are and how they behave. We break that split down in paid search versus paid social, and cover the basics in what paid advertising is and how it works.

The important word is control. Done properly, you choose the audience, build creative for a goal, send people to a page designed to convert, and measure the sales that come back. The boost button gives almost none of that away, which is exactly why it feels easy and performs poorly.

Boosting a post versus running a campaign

This is the difference that decides whether social advertising makes you money or just makes you feel busy. They look similar and behave nothing alike.

None of this means boosting is evil. It has its place for genuine reach on a strong organic post. It’s just not a growth strategy, and treating it like one is why so many businesses conclude that social media advertising doesn’t work.

The platforms, and who each one suits

Social media advertising isn’t one channel, it’s several, each with its own audience and strengths.

• Meta (Facebook and Instagram) is the default for most businesses, with the deepest targeting and the widest creative range, strong for both awareness and conversion.
• TikTok gives fast reach when a video lands, and suits consumer products and lifestyle brands that can make short video.
• Pinterest reaches planners and buyers in visual niches like home, fashion and food, with content that lives far longer than a typical post.
• LinkedIn is the B2B specialist, targeting by job title, industry and company size for high-value leads.
• Reddit reaches engaged, topic-specific communities, as long as your tone reads as one of them rather than an ad.

For most Australian businesses the honest answer is to start with Meta and prove it before adding another platform. If you want the full breakdown, including where Google fits, read which advertising platform is best for your business, and see how we run the social side with Meta ads management.

What social media advertising costs

There’s no set price, and anyone quoting you one hasn’t asked enough questions. What you pay per result is driven by how competitive your audience is, how good your creative is, and how strong your offer is. A sharp ad with a clear offer to a well-chosen audience costs a fraction per sale of a boosted post to everyone.

The better way to think about it is to work back from a goal. Decide what a customer is worth, what return you need, and let that set the budget rather than a magic monthly number. For a small business that often means starting lean on one platform and scaling only what proves itself. We walk through the real numbers in what paid advertising costs and how to size your spend in setting the right budget for paid ads.

Does social media advertising actually work?

Yes, but not the way most businesses run it. It works when the offer, the audience and the creative line up, and when you give the platform time to learn who converts. It fails when you boost posts, judge results on day two, or send expensive clicks to a page that can’t close the sale.

Two things trip people up most. The first is patience: campaigns need a learning period before the numbers settle, which we cover in how quickly paid ads work. The second is the funnel: if the ads pull clicks but no sales, the problem is almost always the page or the offer, not the platform. That’s the subject of why your ads get clicks but no sales.

From the studio Nearly every account we take over has months of boosted posts behind it and nothing to show but a nice-looking page. The owner tells me social media advertising doesn’t work for their business, and they’re half right, because what they were doing wasn’t really advertising. The day we switch from boosting to a proper campaign, with a real offer and a page built to convert, is usually the day the phone starts ringing. The platform was never the problem.

How to start without burning budget

You don’t need a big budget to start, you need a real campaign instead of a boosted post. Work through it in order.

1. Pick one goal and one platform. Sales or leads, on the platform where your audience already is. Prove one before you add a second.
2. Build for the goal, not the feed. Make a few ads with a clear offer and a reason to act now, rather than boosting whatever performed organically.
3. Send traffic somewhere that converts. The best ad in the world loses money against a weak landing page.
4. Test, then scale. Run a small budget, compare your creatives with A/B testing, and put money behind the winner.
5. Bring people back. Most people don’t buy on the first visit, so retargeting is where a lot of the profit quietly lives.

Measure what matters, not what flatters

Likes and reach feel good and pay nothing. The metrics that matter tie spend to money: cost per sale, return on ad spend, and your blended marketing efficiency ratio across the whole business. Judge a campaign on those, give it a fair run, and you’ll make far better decisions than any dashboard of vanity numbers allows.

Common mistakes that waste your budget

• Boosting posts instead of running structured campaigns.
• Sending paid traffic to a home page or a weak offer with no clear next step.
• Judging results in the first few days, before the platform has learned.
• Chasing likes and reach instead of sales and leads.
• Running one ad with no testing, so you never find what actually works.

The bottom line

Social media advertising works, and works well, when you treat it as a demand engine rather than a button. Choose the platform from your audience, build real campaigns with a real offer, send the traffic somewhere that converts, and measure the sales that come back. Do that and social becomes one of the most reliable growth channels you have.

Frequently asked questions

What’s social media advertising?

Social media advertising is paying to run ads on social platforms like Facebook, Instagram, TikTok, LinkedIn, Pinterest and Reddit, with control over who sees them and what you want them to do. Unlike boosting a post, a real campaign uses targeting, purpose-built creative and a funnel to drive sales or leads, not just likes.

Does social media advertising work?

Yes, when it’s run properly. It works when the offer, audience and creative align and you give the platform time to learn who converts. It tends to fail when businesses boost posts, judge results too early, or send clicks to a page that can’t close the sale.

How much does social media advertising cost?

There’s no fixed price. What you pay per result depends on how competitive your audience is, how strong your creative and offer are, and your goal. The smarter approach is to work back from what a customer is worth and the return you need, then set the budget from there rather than a flat monthly figure.

Which social media platform is best for advertising?

For most businesses, Meta, across Facebook and Instagram, because of its targeting and creative range. TikTok suits short video and consumer products, Pinterest suits visual niches, LinkedIn suits B2B, and Reddit suits engaged communities. Start with one that matches your audience and prove it before adding another.

Is social media advertising worth it for a small business?

It can be one of the best-value channels a small business has, but only as real campaigns, not boosted posts. Start lean on a single platform, send traffic to a page built to convert, measure the sales, and scale only what proves profitable.

What’s the difference between boosting a post and a social media ad campaign?

Boosting pushes an existing post to a broad audience and optimises for cheap engagement. A campaign lets you choose the exact audience, build ads for a specific goal, test creative, retarget, and measure revenue. Boosting buys likes, campaigns buy customers.
