CPC — cost per click — is what you pay each time someone clicks your ad. It's the price of admission to paid search, and like any price, it's only "high" or "low" relative to what the click is worth to you.
How CPC is set
You don't pay your bid — you pay just enough to beat the advertiser below you, discounted by your Quality Score. This is the second-price auction at the heart of how Google Ads works: better relevance literally costs less. Two advertisers bidding ₹100 can pay wildly different CPCs depending on their ad quality and landing pages.
What drives CPC up
- Competition. More bidders for the same keyword — legal, finance and B2B software are the classic expensive arenas.
- Commercial intent. "Buy", "hire" and "near me" keywords cost more because they convert better. That's usually a fair trade.
- Low Quality Score. Irrelevant ads and slow landing pages attract a relevance penalty on every single click.
- Broad targeting. Bidding on loose terms invites irrelevant clicks that inflate your average without producing enquiries.
What drives CPC down
- Tighter relevance. Ad text that mirrors the keyword, landing pages built for the specific search.
- Long-tail keywords. "Commercial kitchen cleaning services Kochi" costs less — and converts better — than "cleaning services".
- Negative keywords. Every irrelevant click you block lowers your average cost and raises your conversion rate.
- Better CTR. Higher click-through feeds Quality Score, which discounts every future click.
Is your CPC actually bad?
Stop judging CPC in isolation. The only question is: does the maths work? If your average enquiry is worth ₹20,000, a ₹200 CPC at a 5% conversion rate costs ₹4,000 per enquiry — an excellent trade. A ₹30 CPC that never converts is infinitely expensive. Track cost per enquiry and cost per acquired customer; CPC is just a lever, not the goal.
