Paid social media: formats, costs and targeting explained

Paid social media is advertising you buy on social platforms — Meta, LinkedIn, TikTok, X and others — to reach audiences beyond your existing followers. You pay to place ads in users' feeds, stories or timelines, targeting them by demographics, interests or behaviour. Every placement is bought, every result is measurable.

Key takeaways

• Paid social and organic social are distinct disciplines: organic builds an audience over time; paid reaches a defined audience immediately, the moment your budget is live.

• The main paid social platforms for UK small businesses are Meta (Facebook and Instagram), LinkedIn, TikTok and X, each suited to a different objective and audience type.

• Targeting is what separates paid social from almost every other advertising channel: you choose who sees your ad by age, location, job title, interest, behaviour or even whether they have visited your website.

• Costs are set by auction: you bid against other advertisers for the same audience, so budget alone does not determine results. Creative quality and audience relevance move the needle just as much.

• A small business should consider paid social when it has a clear offer, a defined audience and a way of measuring what happens after the click.

What does paid social actually mean?

Paid social means buying advertising space on a social media platform. You create an ad, define who should see it, set a budget and bid, and the platform's algorithm delivers the ad to the audience you have specified.

The word "paid" is doing important work here. Organic social — posting content on your business page — costs time but not placement fees. Paid social costs money for every impression or click, and in return it gives you reach, speed and precision that organic posting cannot match.

This distinction matters for planning. Organic content builds credibility and keeps existing followers warm. Paid campaigns reach new audiences immediately, making them the right tool when you need to generate leads or drive sales within a defined window.

Which formats does paid social actually use?

Paid social ads take several forms, and the right format depends on your objective.

Single image ads are the simplest entry point. One image, a headline, a description and a call to action. They work well for direct response: a specific product, a limited offer, a consultation request.

Carousel ads let you show multiple images or videos in a swipeable sequence. They suit businesses with a range of products, or anyone who needs a few steps to explain what they do.

Video ads appear in-feed or as pre-roll content. Short-form video (under 15 seconds) consistently drives higher engagement on Meta and TikTok. Longer videos work better for consideration-stage campaigns where the viewer already knows the problem you solve.

Story and Reel ads run between organic stories or short-form video content. They take up the full screen, which forces attention, but they also require vertical creative produced specifically for that format.

Lead generation ads open a native form within the platform rather than sending the user to your website. This reduces friction and tends to improve completion rates, though the leads require careful qualification.

How does paid social targeting work?

Targeting is the mechanism that makes paid social genuinely useful. Rather than broadcasting to anyone who happens to be in the room, you define the audience before you spend a penny.

The main targeting options across platforms are:

1. Demographic targeting — age, gender, location, language, household income (available on some platforms).

2. Interest and behaviour targeting — people who have engaged with content about topics relevant to your product or service.

3. Job-based targeting — particularly powerful on LinkedIn, where you can target by job title, seniority, company size or industry.

4. Custom audiences — uploading your own customer list, or targeting people who have visited your website (via a tracking pixel) or engaged with your existing content.

5. Lookalike audiences — asking the platform to find new users who share characteristics with your best existing customers.

Custom and lookalike audiences typically produce the strongest return because they are grounded in real data about people who have already shown interest. Starting with cold interest-based targeting is perfectly workable, but it usually requires more budget before the algorithm finds its stride.

What does paid social cost, and how is it priced?

Paid social is priced by auction. Every time a user loads their feed, an auction runs in milliseconds to decide which advertiser wins that placement. You set a daily or lifetime budget and a bid strategy, and the platform spends within those limits.

The two most common pricing models are cost per click (CPC) and cost per thousand impressions (CPM). Which you use depends on your objective: clicks for direct response, impressions for brand awareness.

Costs vary considerably by platform and audience. LinkedIn is significantly more expensive per click than Meta because its professional targeting is harder to replicate elsewhere. TikTok has historically offered lower CPMs but requires strong creative to stop the scroll.

For a UK small business, a sensible starting point is a daily budget of £20 to £50 per campaign, enough to gather data within two to three weeks without committing to unproven ad sets. Scale what works; pause what does not.

When should a small business use paid social?

Paid social earns its place when three conditions are met: you have a clearly defined offer, you know who you want to reach, and you have a way of tracking what happens after someone clicks.

Without tracking, you are spending money without knowing whether it works. This is the most common reason paid social "doesn't work" for small businesses, and it is almost always a measurement problem rather than a platform problem. The team at Revolve, which works with UK SMEs across a range of sectors, treats conversion tracking as a prerequisite before any paid campaign goes live.

If you are not yet ready to invest in paid social, organic social and SEO can build the audience and content foundation that makes paid campaigns more effective when you do launch them.

Limitations worth knowing before you commit

Paid social stops the moment the budget stops. Unlike SEO, which builds lasting visibility, paid social delivers results only while you are actively spending. That is not a reason to avoid it, but it is a reason to treat it as part of a broader marketing mix rather than the whole strategy.

Creative fatigue is a real operational cost. Audiences see the same ads repeatedly and stop responding. Running paid social well means refreshing creative regularly, which takes time and resource beyond the media budget itself.

Finally, attribution is genuinely difficult across platforms. Meta and Google each claim credit for the same conversion, which makes cross-channel reporting messy. A reliable tracking setup, not platform dashboards alone, is what gives you an honest picture.

Frequently asked questions

What is the difference between paid social and paid search? Paid search (Google Ads, for example) targets people who are actively searching for something. Paid social targets people based on who they are, not what they are searching for right now. Search captures existing demand; social creates and shapes demand.

Is paid social worth it for a very small budget? Yes, but with realistic expectations. A budget of £500 per month is enough to test one or two audiences on Meta and learn what resonates. It is not enough to scale. The value at this stage is data: which creative works, which audience responds, what your cost per lead actually is.

Which platform is best for B2B paid social? LinkedIn is the default for B2B because its professional targeting, job title, seniority, company size, is unmatched. It costs more per click than Meta, but the audience quality is typically higher for business-to-business offers.

What is a pixel, and do I need one? A pixel is a small piece of code you place on your website that allows the ad platform to track what visitors do after clicking your ad. You need one. Without it, you cannot run retargeting campaigns, build custom audiences, or measure conversions accurately. It takes around 20 minutes to install and is non-negotiable.

How long before I see results from paid social? Most ad platforms enter a "learning phase" when a new campaign launches, typically lasting seven to fourteen days, during which the algorithm tests audiences and optimises delivery. Meaningful results, enough data to make decisions, usually take three to four weeks of consistent spending.
