Marketing Glossary
7 marketing terms defined
This marketing glossary explains the marketing terms you actually run into at work, in plain English and with real examples. It covers digital marketing terms like ROAS, CTR and attribution, performance marketing terms you need for budget conversations, plus brand, SEO, content and analytics vocabulary. Every entry gives you a straight marketing definition first, then shows the concept working in a real campaign. Where a free tool on this site does the calculation for you, the entry links straight to it.
Brand Equity
Brand equity is the commercial value a brand name adds beyond the product itself. It shows up as pricing power, customer loyalty and cheaper acquisition.
Performance MarketingClick-Through Rate (CTR)
Click-through rate (CTR) is the share of people who clicked after seeing your ad or listing. It measures whether your message earned the click.
Performance MarketingConversion Rate
Conversion rate is the share of visitors who complete the action you wanted. It is the multiplier that makes every other marketing number better or worse.
Performance MarketingCost Per Click (CPC)
Cost per click (CPC) is what you pay each time someone clicks your ad. It is the price of attention, and it sets the floor on what your traffic costs.
Performance MarketingCustomer Acquisition Cost (CAC)
Customer acquisition cost (CAC) is the total spend required to win one new customer. It is the number that decides whether growth is sustainable.
Performance MarketingCustomer Lifetime Value (LTV)
Customer lifetime value (LTV) is the total profit a customer generates across their whole relationship with you, not just their first purchase.
Performance MarketingReturn on Ad Spend (ROAS)
Return on ad spend (ROAS) measures how much revenue you earn for every unit of currency spent on advertising. It is the core efficiency metric in paid media.

How to use this glossary
Marketing has a vocabulary problem. The same idea gets three names depending on who is talking, and half the terms get used confidently by people who could not define them if pressed. That costs you real money when a budget conversation turns on whether someone means ROAS or ROI, or whether "reach" is the number they think it is.
Each entry here is written to be read in under two minutes. You get the definition first, then how the thing actually works, then a real campaign where you can see it operating. If you learn better from examples than definitions, start with the marketing case studies and follow the glossary links back from there. If a term involves a calculation, check the free tools, since several of them do the maths for you.
Where it is relevant, entries include Indian marketing context alongside the usual US and UK examples, because pricing, margin structures and channel mix look different here, and a break-even ROAS that works in one market can quietly sink you in another.
