TL;DR
PPC means pay-per-click: an advertising model where a click creates a charge. CPC means cost per click. It can describe the price of a click, an average across clicks, or a bidding model. They are related terms rather than two competing marketing strategies.
For a small business, the useful question is what those clicks produce. An affordable visit from someone outside your service area may be worth less than a more expensive visit from someone who needs exactly what you sell.
Separate the click price from the business result
Google defines average CPC as the total cost of clicks divided by the number of clicks. This differs from maximum CPC, which is a bid setting rather than your observed average price. The platform's CPC explanation covers that distinction.
Here is a hypothetical calculation, not a market benchmark or service quote. If an advertiser spends £240 on 80 clicks, average CPC is £3. If those visits produce four recorded enquiries, advertising cost per recorded enquiry is £60.
Neither number tells you whether the enquiries are useful. If only one enquiry matches the service and location, cost per qualified enquiry is £240. If none becomes a sale, a low click price has not made that spend profitable.
Define a qualified enquiry before launching
Write down the criteria your team can actually assess. For a builder, that might include project type, location and a realistic timescale. For a specialist business service, it may include business size and the problem the buyer needs solved.
Use the same criteria when reviewing paid and organic enquiries. Otherwise one channel may appear stronger simply because different standards are being applied.
Keep recorded website actions separate from qualified leads. Form submissions can include spam, suppliers and job applications. Phone clicks show an intention to call, not proof that a conversation happened or that work was booked.
Read the landing page as a customer
An ad promising boiler servicing should lead to a page explaining boiler servicing. A general homepage can leave visitors hunting for the offer they expected.
Check that the page names the service, the area covered and any essential limitations. Explain how to enquire and what information is useful. Test the page on a phone and complete the form yourself.
If unsuitable enquiries dominate, review both targeting and page wording. More traffic is unlikely to solve a mismatch between the promise and the actual service. The service-page checklist provides a practical starting point.
Ask what is included in the reported cost
Platform spend is only one cost. Management fees, landing-page work, creative and tracking can affect the total investment. Keep the reporting labels explicit so that advertising-only figures are not confused with overall acquisition costs.
Also consider the sales cycle. A quotation for a substantial project may take weeks to turn into a decision. Review completed sales when enough time has passed, and keep pending enquiries visible rather than silently counting them as failures.
Small samples can be misleading. One unusually valuable job can make a short test look excellent; one quiet week can make it look poor. Interpret the result alongside demand, capacity and the number of opportunities actually recorded.
Use CPC as a diagnostic, not a target on its own
A rising CPC can prompt investigation into competition, targeting or ad relevance. A falling CPC can be useful, but only if lead quality and sales economics remain acceptable. Cheap traffic is not the objective.
For organic search, there is no paid click charge, but research, content and website work still cost time and money. The SEO versus Google Ads guide explains how to compare the wider decision.
