Pay-per-click (PPC)

PPC is most closely tied to search ads, where businesses bid to appear above or below the free results for chosen searches. The same model is used on social networks, shopping platforms and display networks. Google Ads is the largest example, and Microsoft Advertising runs a similar system for Bing.

PPC is not the same as SEO. Paid listings appear as soon as a campaign is live and stop when the budget does. Organic rankings take longer to earn but do not charge per click. Many businesses use both, sometimes using ad data to learn which searches are worth targeting organically.

How it works

On search platforms, the advertiser chooses keywords, writes ads and sets a budget and a bidding approach. When someone searches, the platform runs an auction among the ads eligible for that search. The winners and their order depend on the bid and on the platform's assessment of ad quality and relevance, not on money alone. When a user clicks, the advertiser is charged the cost per click set by that auction.

Targeting goes beyond keywords. Advertisers can limit ads by location, language, device, time of day and audience lists, and add negative keywords to block searches they do not want, such as "free" or "jobs" for a paid service. Bidding can be manual or automated, where the platform adjusts bids for each auction to reach a goal such as conversions at a target cost.

To judge PPC properly, connect it to conversion tracking. Clicks and click-through rate show interest, but the useful figure is cost per enquiry or sale. Look at the search terms report regularly; it shows the real searches that triggered your ads, which often include irrelevant ones to exclude. Some campaign types also charge per impression or per view rather than per click, so check the billing model of each campaign.

Example

An emergency locksmith covers one city. It runs search ads for phrases such as "locksmith near me" and "locked out", shown only within its service area and only during the hours it can answer the phone. Ads include the phone number and an extension showing the call-out promise.

The first month's search terms report shows clicks for "how to pick a lock" and "locksmith course", which will never become jobs. The owner adds those as negative keywords. With calls tracked as conversions, the locksmith calculates cost per call and cost per completed job, and finds that late-evening searches cost more per click but more often turn into paid work.

Why it matters for your business

PPC can bring enquiries within days, which helps new businesses, seasonal offers and services where organic rankings are hard to win. You control the budget closely and can turn it off at any time. The costs are real: competitive searches can be expensive, poorly set-up campaigns waste money on irrelevant clicks, and results stop the moment spending stops. It works best when the landing page converts well and the value of a customer comfortably covers the cost of acquiring one. A sensible first step is a small, tightly targeted campaign on your highest-intent searches, which shows your real cost per enquiry before you commit a larger budget.

Common mistakes

• Sending all ad traffic to the homepage instead of a page that matches the search and the offer.
• Leaving broad keyword matching unchecked, so ads appear for loosely related searches that never convert.
• Running campaigns without conversion tracking and judging them by clicks alone.
• Setting up campaigns once and never reviewing search terms, bids or results.

Questions people ask

How much does PPC cost?

There is no fixed price. You set a daily or monthly budget, and the cost of each click depends on competition for the search, your ad's quality and your location. Some clicks cost very little and others a lot. Start with a budget you can afford to test with and judge it by cost per customer.

Is PPC better than SEO?

Neither is better in general. PPC brings visibility quickly and stops when you stop paying. SEO takes longer but can bring steady visits without a charge per click. Many businesses use PPC for immediate leads and testing, while building organic visibility for the longer term.

How long does PPC take to work?

Ads can start showing within hours of approval, so clicks can arrive the same day. Getting good results usually takes longer, often several weeks, because you need data to remove wasted searches, refine bids and improve the landing page. Automated bidding also needs conversion data before it settles.
