PPC
Last updated September 2026
Pay-per-click (PPC) is an advertising model where an advertiser pays only when a user clicks their ad, rather than for impressions or placement alone. It covers search, display, shopping, and social ad formats, and is the umbrella term under which CPC, CPM, and CPA describe specific ways spend gets counted.
PPC is the pricing model most people mean when they say paid search or paid media generally, but it spans far more than one platform. Google Ads, Microsoft Ads, Meta, and LinkedIn all run auction-based PPC systems, each with its own targeting options and bidding mechanics.
01
How the auction actually works
Placement and price come from a combination of the advertiser's bid, a relevance measure like Quality Score, and the expected impact of ad extensions and assets. The advertiser rarely pays the full maximum bid, the auction mechanics typically charge closer to the minimum needed to beat the next-best competitor.

Why PPC needs clean measurement more than most channels
Because spend is direct and immediate, a client feels PPC waste faster than almost any other channel. Without conversion tracking wired up correctly, optimizing a campaign is guessing with real money. That is why Conduit treats GTM, GA4, and Conversion Clarity setup, verified before launch, as a hard prerequisite rather than a nice-to-have.
For agencies running PPC under white label, the deliverable is not just clicks, it is a client-ready explanation of what was spent, what it produced, and why the channel mix looks the way it does, and that explanation is only possible when the tracking behind it was built correctly from day one.
The channels where PPC delivers fastest are typically ones with clear, definable purchase intent, searches for a specific service or product, where the ad is answering a question the searcher has already decided to act on, and where current benchmarks confirm that intent converts at a predictable rate. Agencies new to a PPC account should audit the existing conversion tracking before touching bids or budgets, since flawed data will make even a well-run account look like it is underperforming.
