4Ps of Marketing
The 4Ps of marketing are product, price, place and promotion: the four decisions you control when you take something to market. They only work together.
Brand StrategyBrand 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.
Brand StrategyBrand Identity
Brand identity is the set of things a business controls to be recognised: name, logo, colours, type, packaging and voice. Its job is to be spotted fast.
Brand StrategyBrand Positioning
Brand positioning is the specific place a brand chooses to hold in a customer's mind compared with rivals, and the one reason it gives people to choose it.
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.
Content MarketingContent Marketing
Content marketing wins customers by publishing things your audience genuinely wants to read, watch or use. It builds slowly, then pays back for years.
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 Acquisition (CPA)
Cost per acquisition (CPA) is what a campaign or channel spends to produce one tracked conversion, such as a sale, sign-up or lead. It is a channel metric.
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.
E-commerce MarketingDirect to Consumer (D2C)
Direct to consumer (D2C) means a brand sells straight to its customers through its own website, app or stores, with no retailer or distributor in between.
SEOE-E-A-T
E-E-A-T stands for Experience, Expertise, Authoritativeness and Trustworthiness: the qualities Google's raters use to judge whether content deserves trust.
Email MarketingEmail Marketing
Email marketing is sending messages to people who asked to hear from you. It is the one major channel you own outright, with no algorithm deciding reach.
Social Media MarketingEngagement Rate
Engagement rate is the share of people who interact with your content through likes, comments, shares or saves. It shows whether a post earned a response.
Content MarketingEvergreen Content
Evergreen content stays useful long after you publish it, because the question it answers doesn't expire. It earns traffic and links month after month.
SEOGenerative Engine Optimization (GEO)
Generative engine optimization (GEO) means getting your content cited as a source inside answers written by AI tools like ChatGPT and Perplexity.
Analytics and DataIncremental Lift
Incremental lift is the share of sales or sign-ups your marketing actually caused, measured against a control group that never saw the campaign at all.
Paid AdvertisingKeyword Match Type
A keyword match type is the setting that decides how closely a search must match your keyword before your ad can show. It controls both reach and waste.
Marketing FundamentalsMarketing Funnel
A marketing funnel maps the stages people pass through from first hearing about you to buying. Useful for planning, misleading if you take it literally.
Paid AdvertisingPay-Per-Click Advertising (PPC)
Pay-per-click (PPC) is an ad model where you pay only for clicks. It powers search, social and display ads, and rents traffic rather than owning it.
Performance Marketing Full guideReturn 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.
SEOSearch Engine Optimization (SEO)
Search engine optimization (SEO) is the work of getting your pages found, understood and ranked in unpaid search results when people want what you offer.
SEOSearch Intent
Search intent is the goal behind a search: what the person actually wants to do. Match it and you can rank. Miss it and the right keyword will not help.
Content MarketingTopical Authority
Topical authority is the trust a website earns on a subject by covering it deeply and in an organised way, so search engines treat it as a go-to source.
Content MarketingUser-Generated Content (UGC)
User-generated content (UGC) is content about your brand made by customers, not by you: reviews, photos, videos and posts that people trust more than ads.
Analytics and DataUTM Parameters
UTM parameters are tags added to a link that tell your analytics tool where a visitor came from, which campaign sent them and through which channel.
No terms match that filter. Try clearing the search or picking another category.
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.
