What Is PPC? A Plain-English Guide to Pay-Per-Click Advertising

PPC stands for pay-per-click. It is online advertising where you only pay when someone clicks your ad — not when it is shown. You bid to appear at the top of search results or in a social feed, and you are charged only for the clicks you actually get. That is the whole idea in one sentence. The rest of this guide explains how the bidding works, what a click really costs in 2026, and whether it is worth it for a small business.

How PPC Actually Works

When you search for something on Google, the ads at the top did not simply pay the most to be there. Every time a search happens, Google runs a near-instant auction. Advertisers who have bid on that search term are entered, and Google ranks them using two things: how much they are willing to pay per click, and a quality measure it calls Quality Score — how relevant and useful your ad and landing page are to what the person searched for.

That second part matters more than people expect. A business with a lower bid but a more relevant ad can outrank a competitor throwing more money at it. It means PPC rewards getting the basics right — tight keywords, ads that match the search, and a landing page that answers it — rather than just outspending everyone.

You set a daily budget, a list of search terms you want to appear for, and a maximum you will pay per click. Google never charges more than your daily budget, and you only pay when someone clicks. If your ad shows a thousand times and nobody clicks, you pay nothing.

What Does a Click Cost?

There is no single price. It depends entirely on your industry and how hard competitors are bidding for the same customers.

Budgets vary just as widely. The median Google Ads account spends around $3,127 a month, but that hides a huge spread — roughly a quarter of accounts spend under $1,000 a month, and about a third spend over $10,000 (WordStream, 2025). A local business does not need a five-figure budget. A few hundred pounds a month, spent on a tight set of high-intent local searches, is a perfectly sensible place to start and test.

Does PPC Actually Work?

Used properly, the numbers are hard to argue with.

Two things make PPC powerful for a small business. First, it is instant — you can be at the top of Google for your best search terms today, rather than waiting months for SEO to build. Second, the intent is high. Someone searching “emergency plumber Truro” is not browsing; they are ready to book. PPC puts you in front of them at that exact moment.

The catch is that “used properly” is doing a lot of work in that sentence. PPC punishes sloppiness. Bid on vague terms, send clicks to a weak page, or fail to track which clicks turn into phone calls, and you will spend real money for very little. The businesses that win at PPC are the ones that measure everything and cut what does not pay.

Where PPC Fits for a Local Business

Google still handles the overwhelming majority of searches — 91.27% of the global search market as of mid-2026 (StatCounter) — so for most local businesses, Google Ads is where PPC starts.

The most common mistake we see is treating PPC as a substitute for everything else. It is not. It is the fast lane. It brings leads while your organic rankings and reviews build underneath it, and those take time. The strongest setup is usually both running together: PPC for immediate enquiries, SEO for the long-term foundation that keeps working when you turn the ads off. We break down exactly how to choose in SEO vs PPC.

Google now automates a lot of this through tools like Performance Max, which over a million advertisers already use (Google, 2025). Automation helps, but it also makes it easier to spend money without understanding where it went. That is exactly why call tracking and a human keeping an eye on the numbers matter more, not less.

The One Rule That Decides Whether PPC Pays

Track the outcome, not the click. Most local businesses get more enquiries by phone than by form, and most agencies never connect a phone call back to the ad that caused it. Set up call tracking from day one so every enquiry is traced to the exact search term that triggered it. Then you can pour budget into what brings real work and switch off what does not. Without that, PPC is guesswork with a credit card attached.

If you want that done properly — tight keywords, call tracking from day one, and honest reporting on what each pound actually returned — that is exactly what our Google Ads management in Cornwall is built around. No lock-in, and you see what every click earned.
