PPC (pay-per-click): platforms, costs and when it pays off

Definition

PPC (pay-per-click) is an advertising model in which the advertiser pays for each click – usually in Google Ads, Meta or LinkedIn. It gives immediate visibility but requires an ongoing budget and a strategy to generate a positive return.

What is PPC and how does it work?

In PPC advertising, advertisers bid on keywords or audiences and pay each time a user clicks the ad. The most widely used platform is Google Ads, where ads appear at the top of the search results for relevant queries. The cost per click (CPC) is determined by a combination of the bid and Quality Score – Google's assessment of the ad's relevance and the quality of the landing page.

PPC differs fundamentally from organic SEO: the visibility stops as soon as the budget runs out. That makes PPC a tool for immediate reach rather than necessarily a long-term one, although the insights, data and brand exposure that paid ads bring can create lasting value even after the ad budget has been spent.

Which platforms are used for PPC?

The main PPC platforms have different strengths depending on your goals and audience:

• Google Ads (Search) – Ads appear in the search results for specific keywords. Users have high purchase intent. Suits both B2B and B2C where there is clear search behaviour.
• Google Ads (Display) – Banner ads across Google's partner network. Good for brand building and remarketing.
• Meta Ads (Facebook/Instagram) – Audience-based advertising with detailed demographic and interest-based segments. Strong for B2C and e-commerce.
• LinkedIn Ads – The highest CPC of the big platforms, but uniquely precise targeting by job role, industry and company size. Suits B2B with long sales cycles.
• Microsoft Ads (Bing) – Lower competition and often a lower CPC than Google Ads, with an older and often high-spending audience.

What does a PPC campaign cost?

The cost depends on industry, competition and platform. In Sweden, the CPC for Google Ads generally ranges from SEK 5 to SEK 100 per click:

• Law and finance: SEK 50–200+ per click – the most competitive categories
• B2B SaaS: SEK 30–100 per click
• E-commerce (fashion, home): SEK 5–25 per click
• Local services: SEK 10–50 per click

If you hire a specialist, an agency or management fee comes on top of the click costs. Budget at least SEK 5,000–10,000 a month in ad spend to get enough data to optimise. Below that level, it is hard to draw statistically sound conclusions about what actually works.

ROI on PPC vs SEO – which gives the best return?

That is the wrong question – the two channels should work together and complement each other.

PPC gives immediate visibility and full control: you decide exactly which keywords, times and audiences trigger your ad. The ROI shows up quickly but is tied directly to budget – no money, no visibility.

SEO builds an asset that generates traffic with no ongoing cost per click. The effect takes time (typically 3–12 months for new websites), but it compounds, and the marginal cost per visitor falls over time.

In practice, the most effective budget split often looks like this:

• Short term: PPC for immediate visibility on commercial terms while SEO is being built up
• Medium term: SEO takes over the traffic for terms you rank for, and PPC focuses on high-CPC terms with clear purchase intent
• Long term: PPC is used for remarketing, testing new messaging and covering terms where SEO is not enough

According to data from First Page Sage, organic SEO traffic gives a lower cost per lead in almost every industry and a considerably higher ROI in the long run (748% versus 36%) – but PPC delivers results immediately, which SEO does not.

What decides whether PPC actually pays off?

PPC is profitable when three conditions are met:

• The landing page converts. The click is only the first step. A landing page with an unclear CTA, a slow load time or a weak offer wastes the ad budget however good the ad is.
• Customer value comfortably exceeds the CPC. If the average order is SEK 500 and the conversion rate is 1%, each customer costs 100 clicks × the CPC. With a CPC of SEK 20, that means SEK 2,000 in ad costs per customer – before agency fees.
• Tracking is set up correctly. Without accurate conversion tracking, you are optimising blind. GA4, Google Ads conversions and – for e-commerce – Enhanced Ecommerce are basic requirements.

At SEOS Design, we see PPC as a complement to SEO and AEO – not as a stand-alone solution. A well-built organic presence reduces the dependence on paid traffic and lowers the total cost per acquisition over time.
