PPC glossary & marketing
acronyms explained simply

Online advertising model where advertisers pay only when a user clicks on their ad, rather than for passive impressions.

Unlike legacy media or CPM display where you pay for mere exposure, PPC charges exclusively when a user demonstrates clear intent by clicking through to your website or landing page. Common networks include Google Ads, Microsoft Advertising, Meta, and LinkedIn.

The actual ad spend required to acquire a single desired business outcome (e.g. qualified lead, order, or consultation booking).

CPA is the north-star metric for B2B enterprises and performance e-commerce. You do not optimize for cheap clicks (CPC); you optimize for how much ad spend is needed to place a paying client into your CRM.

The monetary price billed each time an ad auction user clicks on your text, shopping, or display ad.

In Google Ads and Bing auctions, CPC is dynamic and determined in real-time by competitive bids and your Quality Score. Higher landing page relevance directly lowers the CPC you pay for the top ad slot.

Automated personalized ads serving past visitors the exact products, services, or catalog items they viewed on your website.

Standard retargeting delivers static banners to all past visitors. Dynamic Remarketing (Google Dynamic Ads, Meta Catalog Ads) automatically generates creatives featuring the exact SKU, price, and specs the user inspected.

Revenue generated for every single dollar invested in advertising credit.

ROAS evaluates marketing channel efficiency as a percentage or ratio. Unlike ROI (which factors in COGS, operating costs, and overhead), ROAS directly evaluates top-line advertising efficiency.

The percentage of gross revenue consumed by advertising costs (the inverse ratio to ROAS).

Popular in Central Europe as PNO and internationally as COS (Cost of Sale) or ACoS. It allows direct comparison against your gross margin: with a 25% margin, your COS must not exceed 25% to prevent operating loss.

Direct server-to-server data transmission between your website infrastructure and Meta advertising servers.

Browser pixels are increasingly blocked by AdBlockers, Brave, and Apple Safari ITP. Conversions API transmits purchases and leads directly from your cloud backend where browser blockers have zero visibility.

First-party cloud proxy node managing analytics and marketing tags securely on your own infrastructure.

Instead of browsers loading dozens of heavy third-party vendor scripts, your client interacts exclusively with your own proxy. The server validates, strips PII, and transmits data to Google, Meta, and analytics endpoints.

Google DMA-compliant framework transmitting cookieless pings for AI conversion modeling when users decline cookies.

Since March 2024, Google Ads requires Consent Mode v2 parameters (ad_user_data, ad_personalization). When users reject cookies, Google transmits cookieless pings from which machine learning models up to 70% of lost conversions.

Percentage of people who click your ad after viewing it in search results or display placements.

CTR measures creative resonance and search intent match. In Google Search, high CTR (8–15%) signals relevance to user intent, whereas display networks typically average 0.3–1%.

Automated, AI-driven campaign type serving across Search, Shopping, YouTube, Display, Discover, and Maps from a single budget.

Performance Max utilizes Google multimodal machine learning models to dynamically allocate advertising spend across channels based on real-time conversion likelihood.

Total gross margin or revenue generated by a customer across the entire lifecycle of their relationship with your business.

We distinguish Gross Revenue LTV from Gross Margin LTV. In B2B and SaaS, the initial purchase often carries high acquisition overhead; long-term retention and recurring margin determine true profitability.

The total blended sales and marketing expenditure required to acquire one paying customer.

While CPA tracks form submissions or leads, CAC aggregates total advertising, agency fees, sales salaries, and software divided by closed, paid deals.

A 1-to-10 rating assessing the relevance and quality of your keywords, ad copy, and landing page experience.

Composed of Expected CTR, Ad Relevance, and Landing Page Experience. An advertiser with a 9/10 Quality Score can pay up to 50% less for top positions than a competitor with 4/10.

The percentage of impressions your ads received compared to the total volume they were eligible to capture.

If your campaign holds a 40% impression share, 60% of prospective buyers missed your ads. Google Ads breaks down lost share into Search Lost IS (Budget) and Search Lost IS (Rank).

Importing closed CRM contracts and ERP invoice payments back into Google Ads and Meta days or weeks after the initial click.

In B2B, transactions finalize in accounting software (SAP, Salesforce, ERP) weeks after the initial web lead. Enhanced Conversions for Leads and GCLID allow CRM systems to push actual paid revenue back into ad engines, training algorithms to bid on high-value buyers.
