Paid Advertising: Models, Costs and How to Get Started
Paid advertising is any marketing where you pay a platform to show your message to people you choose. It includes search ads on Google and Bing, social ads on LinkedIn, Meta and TikTok, video ads on YouTube, display ads across websites and apps, and sponsorships. The appeal is control: you decide who sees it, when, and how much you spend, and you can usually see results within days. The catch is that results stop when spending stops.
Key takeaways
- Paid advertising buys speed and control. Organic channels buy compounding. Most businesses need both.
- Pick the pricing model that matches your goal: clicks for traffic, impressions for reach, results for conversions.
- Set budgets from your numbers: what a customer is worth and what you can afford to pay to win one.
Why paid advertising matters
It’s the fastest way to reach a precise audience, test an offer or launch something new. You can learn in weeks what organic channels take months to show: which messages, audiences and offers convert. And it reaches the large majority of potential buyers who aren’t searching yet. According to the LinkedIn B2B Institute’s 95-5 rule (with Ehrenberg-Bass, 2021), 95% of potential B2B buyers aren’t ready to buy today, so paid reach is how many brands stay known until they are.
Paid advertising pricing models
| Model | You pay for | Good for | Typical platforms |
|---|---|---|---|
| CPC (cost per click) | Each click | Traffic and leads from intent | Google Ads, Microsoft, LinkedIn |
| CPM (cost per thousand impressions) | Every 1,000 times shown | Reach and awareness | Meta, TikTok, LinkedIn, display |
| CPV (cost per view) | Video views | Video reach and engagement | YouTube |
| CPA or conversion bidding | Optimized toward results | Leads and sales at a target cost | Google, Meta, TikTok smart bidding |
| Flat fee | A fixed placement | Newsletters, podcasts, events | Sponsorships |
Many campaigns now pay per click or impression but let the platform’s algorithm optimize toward conversions you track. That only works if your conversion tracking is accurate.
How to set a test budget: a worked example
| Step | Example |
|---|---|
| Target cost per customer | $500 |
| Lead-to-customer rate | 20% |
| Affordable cost per lead | $500 × 20% = $100 |
| Leads needed to judge a campaign | About 20 |
| Test budget per campaign | 20 × $100 = $2,000 over 4 to 6 weeks |
If your first campaign brings leads at $150, improve targeting, creative or landing page before adding budget. Compare results with your blended customer acquisition cost, not just platform-reported numbers.
Myth vs fact
- MythIf ads aren't profitable in the first week, they don't work.
- FactPlatforms need time and conversion data to optimize, and B2B sales cycles are long. Judge campaigns on enough leads and on lead quality, not on the first few days.
An example from our work
The mistake I see most is a founder turning on ads to fix a sales problem. If your landing page doesn't explain the offer clearly, paid traffic just finds that out faster and charges you for it. Before we launch a campaign, we read the page as a stranger would, tighten the offer, and only then set a test budget.
How to get started with paid advertising
Six steps before you spend
-
Define the goal and the number
Leads, sales or reach, with a target cost per result.
-
Fix tracking
Conversions in GA4 and each ad platform, consent mode where needed, and leads flowing to your CRM.
-
Choose one or two platforms
Search for existing demand, LinkedIn for B2B roles, Meta or TikTok for broad reach and creative.
-
Brief the creative properly
Audience, problem, proof, offer and format. Our creative brief template covers every platform.
-
Launch with a test budget
Two or three ad variants per audience, one landing page per offer.
-
Review weekly, decide monthly
Cut losers, scale winners, and check lead quality with sales.
Common mistakes
- Sending ad clicks to the homepage instead of a matching landing page.
- Optimizing for cheap clicks rather than qualified leads.
- Running ads without excluding existing customers.
- Changing too much too often, so nothing has time to learn.
For the search side, see pay-per-click advertising. To bring back visitors who didn’t convert, add remarketing.
Frequently asked questions
What is the main goal of paid advertising?
To reach a chosen audience quickly and drive a measurable action, such as visits, leads or sales, at a cost that makes business sense.
Is paid advertising expensive?
It depends on your market and audience. Senior B2B audiences cost more per click than broad consumer ones. Start with a test budget large enough to produce about 20 leads.
Can paid advertising work without SEO?
Yes, but you'll pay for every visitor forever. SEO lowers your average cost over time and makes ads work better by building trust.
Which paid advertising platform is best?
The one where your buyers are and your offer fits: Google for active searches, LinkedIn for B2B decision makers, Meta and TikTok for broad reach and visual products.
