Frequently Asked Questions

What is the difference between PPC and SEM?

Search Engine Marketing (SEM) is an umbrella strategy covering all paid marketing efforts on search engine result pages. Pay-Per-Click (PPC) is a specific billing model commonly used within SEM campaigns (as well as paid social and display) where advertisers pay only when a user clicks on an ad.

What is the difference between CPM and CPC pricing?

Under a Cost Per Click (CPC) model, you pay strictly when an ad receives an explicit click, making it ideal for direct-response and conversion campaigns. Under a Cost Per Thousand (CPM) model, you pay for ad exposures (impressions) regardless of clicks, making it best suited for brand awareness and video campaigns.

How does contextual targeting differ from behavioral targeting?

Contextual targeting serves ads based on the surrounding page content, keywords, or topics (e.g., placing a running shoe ad on a marathon advice article) without relying on user tracking. Behavioral targeting tracks an individual’s historical activity across websites to serve relevant ads regardless of the specific page they are currently viewing.

What is a good ROAS in digital advertising?

While a “good” Return on Ad Spend varies by industry margins, a baseline benchmark for direct-to-consumer ecommerce campaigns is 4:1 (or 400% ROAS). High-margin B2B SaaS companies may accept a lower immediate ROAS if they benefit from high Customer Lifetime Value (LTV).
