PPC

PPC stands for pay-per-click, a billing model in which the advertiser pays when someone clicks the ad rather than when the ad appears. The best-known example is Google Search ads, but the model also covers Shopping ads, Microsoft Advertising, and many social formats that offer click-based bidding. In Google Ads you set a bid, which can be a maximum cost-per-click, or let a bid strategy set it for you. What you pay for a click is often less than your maximum bid. Search is the classic form, but pay-per-click also covers product listings, local service ads in some programs, and social and display campaigns that use click-based bidding.

Behind each click is an auction. When someone searches, the platform finds eligible ads and ranks them using bids, expected click-through rate, ad relevance, and landing page experience, among other factors. Google notes that Quality Score is a diagnostic and is not an input in the ad auction itself, but the components it summarizes affect ad rank. Winning and paying are separate steps. The click then costs an amount the system determines, and you pay nothing for impressions that earn no clicks. Other models exist: CPM charges per thousand impressions and CPV charges for video views and related interactions. Your daily budget caps average spend, and platforms may spend somewhat more on some days and less on others, so judge spend over a month, not a day.

PPC interacts with every setting that follows the click. A cheap click is worthless if the landing page fails to convert, so cost per conversion, not cost per click, is the number that matters. Bid strategies like manual CPC give you control over each bid, while automated strategies such as maximize conversions or target CPA set bids using conversion data. Match types, negative keywords, and geography narrow who clicks. Budget caps total spend per day. Conversion tracking is the connecting piece: without it, automated bidding has nothing to learn from. Match types control which queries trigger your keyword, from exact to broad, and negative keywords block unwanted queries. Reviewing the search terms report weekly in the first months finds waste quickly.

The persistent confusion is treating PPC as a synonym for Google Search ads. It is a billing model, and many platforms now bill by impression or by outcome instead. A second mistake is paying for clicks that cannot buy, such as job seekers, students, or people far outside your service area; negative keywords and location settings fix this. A third is ignoring click fraud and accidental taps on mobile and display, which show up as clicks with no sessions or instant bounces. Finally, many accounts chase traffic volume rather than profit per click. Quality Score, shown on a one to ten scale at keyword level, rates expected click-through rate, ad relevance, and landing page experience. Google says it is a diagnostic tool and not an input to the auction.

Read PPC as a chain: impressions, click-through rate, cost per click, conversion rate, cost per conversion, and revenue per conversion. A drop in any link shows where the problem sits. This week, calculate your break-even cost per conversion from your margin, compare it with your actual cost per conversion by campaign, and review your search terms report for wasted spend. Add negative keywords for the irrelevant queries, and pause any campaign that spends steadily without conversions after a fair amount of data. Set a break-even cost per conversion before you launch, and write it where everyone can see it. Make one change at a time and write it down. Accounts improve fastest when you can tell which edit, such as a new negative list or a new landing page, caused a change.
