The Marketing Concept Vault: 40 Concepts, Sourced and Ready to Use

What it is: A loss feels heavier than an equal gain. 'Don't lose ₹500' beats 'save ₹500' when people already own the ₹500.
Coined by: Daniel Kahneman and Amos Tversky, 'Prospect Theory', Econometrica 47 (1979).
Real example: 'Your ₹500 cashback expires tonight' beats 'Get ₹500 cashback' for points people already hold.
Use it today: (10 min) Rewrite one renewal or reminder line as what they keep. Before: "Renew to get monthly reports." After: "Renew to keep your rankings report and 12 months of history." Use gain framing on new offers.

Common mistake: Using loss framing on new purchases (nothing to lose yet, so it reads as a threat), or inventing a loss that isn't real.

What it is: The same fact in different words changes the choice.
Coined by: Amos Tversky and Daniel Kahneman, 'The Framing of Decisions and the Psychology of Choice', Science 211 (1981).
Real example: '95% fat free' and '5% fat' describe the same yoghurt. One sells better.
Use it today: (15 min) Write your main claim twice. Gain: "Save 6 hours a week." Loss: "Stop losing 6 hours a week." Put one in an email subject line and the other in the next send. Keep the facts identical.

Common mistake: Framing that changes the facts. Reframe the truth, never replace it.

What it is: People copy what others like them do, especially when unsure.
Coined by: Robert Cialdini, Influence (1984). Aileen Lee named five types (expert, celebrity, user, wisdom of crowds, friends) in TechCrunch, 2011.
Real example: Goldstein, Cialdini and Griskevicius (Journal of Consumer Research, 2008): hotel towel cards saying most guests reuse towels beat a plain environmental message.
Use it today: (20 min) Replace one vague testimonial with a specific one. Ask a happy client: "What was the problem before, what changed, and how fast?" Use their words: "Fixed my GST notice in two days." Add their name and role only with permission.

Common mistake: Leaning on celebrity or vague praise. Specific proof from people like the buyer works best; friends forwarding you beats everything.

What it is: Things that are harder to get feel more valuable.
Coined by: Worchel, Lee and Adewole, Journal of Personality and Social Psychology (1975): cookies from a near-empty jar were rated more desirable. Cialdini made it a principle in Influence (1984).
Real example: OnePlus sold the OnePlus One by invite only in 2014. Real limits, so it built hype, not lawsuits.
Use it today: (15 min) Search your site and emails for "only", "left", "ends", "limited". Keep only lines that are true. For a service, replace fake urgency with real capacity: "I take 4 new clients a month. 2 spots open for December."

Common mistake: Fake timers and fake stock. India's CCPA listed 'false urgency' as a dark pattern in its November 2023 guidelines.

What it is: Give something useful first and people feel they owe you.
Coined by: Dennis Regan, Journal of Experimental Social Psychology (1971): people bought more raffle tickets from someone who had first given them a free Coke. Cialdini, Influence (1984).
Real example: HubSpot's free tools and free courses build goodwill long before the sales call.
Use it today: (25 min) Give one finished thing with no catch. Example: record a 3-minute Loom reviewing one page of a prospect's site and send it with "No pitch, thought this would help." Finished beats a teaser.

Common mistake: A 'gift' with strings attached. If it feels like bait, the debt never forms.

What it is: We defer to experts and to signals of expertise.
Coined by: Robert Cialdini, Influence (1984), drawing on Stanley Milgram's obedience studies (1963).
Real example: 'Dentist recommended' works when the dentist is real and named.
Use it today: (10 min) Add one true proof line next to your main button. Template: "[Years] doing [skill] · [what you run or did] · [one named result or client, with permission]." Remove any badge or logo you can't back up.

Common mistake: Fake badges, borrowed logos or 'as seen in' for a site that never mentioned you.

What it is: After a small yes, people tend to say a bigger yes to stay consistent.
Coined by: Freedman and Fraser, 'Compliance Without Pressure: The Foot-in-the-Door Technique', JPSP (1966). Cialdini, Influence (1984).
Real example: Free trials and quizzes before checkout get a small commitment first.
Use it today: (20 min) Add a tiny first step before your big ask. Example: replace "Book a 60-minute call" with "Answer 2 questions and get a free 1-page audit". The call ask comes after the audit.

Common mistake: Asking for the big yes first (book a 60-minute call) from someone who just met you.

What it is: People say yes to 'us'. Shared identity beats simple liking.
Coined by: Robert Cialdini, Pre-Suasion (2016), added it as the seventh principle.
Real example: CRED's founder describes its mission as serving 'the creditworthy', a group members are proud to belong to.
Use it today: (10 min) Find every "for businesses" or "for everyone" on your site and replace one with a named group. Example: "For founders who still do their own SEO."

Common mistake: A fake tribe. If the identity isn't real to the buyer, it reads as flattery.

What it is: We value things more once we feel they are ours.
Coined by: Kahneman, Knetsch and Thaler, Journal of Political Economy (1990): people given a mug asked for much more to sell it than others would pay to buy it.
Real example: Lenskart's home trial sends a specialist with frames to try at home, with no obligation to buy.
Use it today: (25 min) Let them hold it before they buy. Example: send a sample report run on their own site, or set up their trial with their data already in it. Then follow up with "Want to keep this running?"

Common mistake: Trials so short or empty that nothing ever feels owned.

What it is: Too many options can mean fewer purchases.
Coined by: Sheena Iyengar and Mark Lepper, JPSP (2000): a display of 6 jams led to far more purchases than a display of 24. Later meta-analyses (Scheibehenne et al., 2010) found the effect depends on context.
Real example: Most SaaS pricing pages settle on three plans, not eight.
Use it today: (15 min) Count the options on your pricing or services page. More than 3–4? Group the rest under "Custom" and mark one plan "Most picked".

Common mistake: Treating it as a law. Sometimes more choice helps (experts, clear categories).

What it is: People tend to stick with whatever is pre-selected.
Coined by: Eric Johnson and Daniel Goldstein, 'Do Defaults Save Lives?', Science (2003): organ donor rates were far higher in opt-out countries.
Real example: Pre-selected annual billing on pricing pages.
Use it today: (10 min) Decide which option is genuinely best for most buyers and pre-select it (e.g. annual billing, standard package). Never pre-tick paid add-ons.

Common mistake: Pre-ticking add-ons people didn't ask for. That is a dark pattern ('basket sneaking') in India's 2023 guidelines.

What it is: People judge an experience mostly by its best (or worst) moment and how it ended.
Coined by: Kahneman, Fredrickson, Schreiber and Redelmeier, Psychological Science (1993); Redelmeier and Kahneman, Pain (1996), colonoscopy study.
Real example: Redelmeier and Kahneman's colonoscopy patients who had a gentler last few minutes rated the whole procedure as less unpleasant, even though it lasted longer.
Use it today: (20 min) Write a 5-line handover template for the end of every project: what we did, what changed, what to watch, what I'd do next, thank you. Send it before the final invoice, not with it.

Common mistake: Spending everything on onboarding and letting the project end with an unpaid-invoice email.

What it is: The first number people see becomes the reference for every number after it.
Coined by: Amos Tversky and Daniel Kahneman, 'Judgment under Uncertainty', Science 185 (1974): after a wheel landed on 10 or 65, median guesses for African UN members were 25% and 45%.
Real example: The crossed-out MRP on Amazon. A pricey thali on a menu that makes everything else look reasonable.
Use it today: (10 min) Reorder one price list or proposal so the premium option comes first. Example: Premium ₹45,000 · Standard ₹25,000 · Basic ₹12,000. Change nothing else and watch which one gets picked.

Common mistake: A fake anchor (an MRP nobody ever paid). It works once, then costs trust.

What it is: A clearly worse option makes the option next to it look like the smart pick.
Coined by: Joel Huber, John Payne and Christopher Puto, Journal of Consumer Research (1982). Dan Ariely's Economist example in Predictably Irrational (2008).
Real example: Ariely's students: web $59, print $125, print + web $125. With the print-only decoy, 84% chose print + web. Without it, 32% did.
Use it today: (20 min) Write your plans side by side. Is there one that makes your target plan look like the obvious value? If not, add a real, worse-value option next to it. Example: Audit only ₹15,000 · Audit + 30-day fixes ₹18,000.

Common mistake: A fake plan nobody can buy. Every plan must be real; it's a comparison, not a trap.

What it is: ₹499 feels much cheaper than ₹500 because we read the left digit first.
Coined by: Manoj Thomas and Vicki Morwitz, 'Penny Wise and Pound Foolish: The Left-Digit Effect in Price Cognition', Journal of Consumer Research (2005).
Real example: ₹99, ₹499, ₹999 price points everywhere in Indian e-commerce.
Use it today: (10 min) Use ₹499/₹999 style prices for small, impulse offers (templates, mini audits). Keep round prices (₹25,000) for premium services. Always show the final price including GST on the first screen.

Common mistake: Charm price on the banner, then 'plus GST, plus delivery' at checkout.

What it is: When people can't judge quality, a higher price reads as better quality. Too cheap reads as 'what's wrong with it?'
Coined by: Akshay Rao and Kent Monroe, meta-analysis in Journal of Marketing Research (1989).
Real example: A ₹500 website audit makes buyers wonder what's missing; a ₹15,000 one gets taken seriously.
Use it today: (20 min) If you're the cheapest in your market, raise one service's price and add one line of proof right next to it. Example: "₹15,000 · includes a 40-point checklist and a 30-minute walkthrough call."

Common mistake: Raising price without raising proof. The signal needs something to back it.

What it is: Three options let different buyers pay what it's worth to them. Most land in the middle.
Coined by: A long-standing retail practice (Sears catalogues used it); no single originator is confirmed.
Real example: Nearly every SaaS pricing page: Starter, Pro, Business.
Use it today: (25 min) Turn one service into three. Template: Basic (the core deliverable) · Standard (core + the add-on most clients ask for) · Premium (everything + priority support). Price Standard as the one you want to sell.

Common mistake: Three tiers with no clear difference, so people can't choose and leave.

What it is: The advertised price grows at checkout through fees added step by step.
Coined by: The term comes from consumer-protection economics (UK Office of Fair Trading, 2010). India's CCPA listed it as a dark pattern in November 2023.
Real example: A ₹999 ticket that ends at ₹1,400 after 'convenience' and 'platform' fees.
Use it today: (10 min) Open your checkout or proposal and add up every fee. Put that total on the first screen or page. Template: "₹18,000 all-in, including GST. No extra fees."

Common mistake: Thinking it's clever. It is a named dark pattern in India and a top reason carts get abandoned.

What it is: A free core product, with paid upgrades for people who need more.
Coined by: The model was named 'freemium' in 2006 (term credited to Jarid Lukin, popularised by investor Fred Wilson's blog).
Real example: Canva, Spotify, Google Search Console's free tier vs paid SEO tools.
Use it today: (20 min) Write two lines. Free: "the one thing that proves value in 10 minutes." Paid: "what they need once it works." Example: free 5-keyword report, paid weekly tracking.

Common mistake: Giving away so much free that nobody needs to pay, or so little that nobody sees the value.

What it is: Top: strangers who need help, not you. Middle: people comparing. Bottom: people ready to buy, who need zero friction.
Coined by: The funnel idea traces to AIDA (E. St. Elmo Lewis, ~1898) and William Townsend's Bond Salesmanship (1924). The TOFU/MOFU/BOFU labels came later from content-marketing practice; no single originator.
Real example: A café: a reel on brewing filter coffee (top), 'our beans vs supermarket beans' (middle), Maps listing + WhatsApp order button (bottom).
Use it today: (15 min) Label your last nine posts T, M or B. All one letter? Make one piece for the missing stage this week. Example for a freelancer: T = "why your site gets no calls", M = "freelancer vs agency", B = "book a free audit" link.

Common mistake: 'Book now' posts shown to strangers. Bottom content, top audience, silence.

What it is: Five numbers for a growing product: Acquisition, Activation, Retention, Referral, Revenue.
Coined by: Dave McClure, 'Startup Metrics for Pirates' talk (2007).
Real example: A SaaS tracks signups (acquisition), first project created (activation), week-4 logins (retention).
Use it today: (25 min) Write one number next to each letter for last month: Acquisition (new visitors or leads), Activation (did the first useful thing), Retention (came back), Referral (sent someone), Revenue. Circle the weakest. Fix only that this month.

Common mistake: Pouring money into Acquisition when Activation or Retention is the leak.

What it is: A loop where each part speeds up the next, so growth compounds instead of restarting each month.
Coined by: Jim Collins, Good to Great (2001). Amazon's version is the famous 'virtuous cycle' Jeff Bezos sketched.
Real example: Amazon: lower prices, more customers, more sellers, more selection, lower costs, lower prices.
Use it today: (20 min) Draw 4 boxes in a circle: happy client → [review/case study/referral] → [new leads] → [more clients] → back to happy client. Add one action to make the first arrow happen automatically, like a review request on day 14.

Common mistake: Drawing a flywheel with no real link between the steps.

What it is: When the market pulls the product out of you: people want it badly enough that growth gets easier.
Coined by: Marc Andreessen, 'The only thing that matters' (2007). Sean Ellis proposed the survey test: if 40% would be 'very disappointed' without it, you're close.
Real example: Ask users 'How would you feel if you could no longer use this?' and count 'very disappointed'.
Use it today: (15 min) Send your last 20 customers one question: "How would you feel if you could no longer use [product]? Very disappointed / Somewhat / Not." Read only the 'very disappointed' answers and copy their words into your homepage.

Common mistake: Scaling ads before fit. Ads amplify whatever you have, including a weak product.

What it is: LTV = what a customer is worth over their lifetime. CAC = what it costs to win one. Growth works only when LTV is well above CAC.
Coined by: Standard unit economics in SaaS and direct marketing; no single originator. A 3:1 LTV:CAC rule of thumb is widely repeated but has no single traceable source, so treat it as a guide.
Real example: A freelancer paying ₹2,000 in ads per client who stays 6 months at ₹10,000/month is fine. One who stays one month at ₹1,500 is not.
Use it today: (20 min) On one line: average monthly fee × average months a client stays = LTV. Total spend on ads, tools and time to win clients last quarter ÷ clients won = CAC. If CAC is close to LTV, stop scaling and fix retention first.

Common mistake: Counting only the first payment as LTV.

What it is: Free, useful value given in exchange for an email or contact.
Coined by: A direct-response marketing term; no single confirmed originator.
Real example: A free checklist sent when someone comments a keyword under a reel.
Use it today: (30 min) Pick the one question people ask you most. Turn your answer into a 1-page checklist. Put it at the end of your most-visited post: "Get the 1-page checklist". Small and finished beats a 60-page ebook.

Common mistake: A 60-page ebook nobody finishes. Small and finished beats big and unread.

What it is: Product, Price, Place, Promotion. Services added People, Process, Physical evidence. The 4Cs flip it to the customer: Consumer, Cost, Convenience, Communication.
Coined by: E. Jerome McCarthy, Basic Marketing (1960). Bernard Booms and Mary Jo Bitner (1981) for the 7Ps. Robert Lauterborn, Advertising Age (1990) for the 4Cs.
Real example: A tiffin service asks where hungry people already search (Google, Swiggy) and what they type. That's Place and Promotion, just in a new order.
Use it today: (20 min) Write your four Ps in reverse. Place: where buyers already look ("Google Maps, WhatsApp"). Promotion: what they type there. Product: what fits that place. Price: last.

Common mistake: Filling four boxes like a form. The mix is a set of questions, not a template.

What it is: A small share of inputs usually drives most results. 80/20 is a rule of thumb, not a fixed ratio.
Coined by: Vilfredo Pareto observed in 1896 that about 80% of Italy's land belonged to about 20% of people. Joseph Juran turned it into 'the vital few and the trivial many'.
Real example: In Search Console, a handful of pages often bring most of a site's clicks.
Use it today: (25 min) Make two columns: revenue per client and hours per client. Rank by revenue per hour. Reprice the bottom one: "From January, this work is ₹X/month to cover the real hours." Or sort Search Console pages by clicks and update the top 10 first.

Common mistake: Quoting '80/20' as a law. Measure your own split.

What it is: Create a market with no direct competition instead of fighting in a crowded one.
Coined by: W. Chan Kim and Renée Mauborgne, Blue Ocean Strategy (2005).
Real example: Cirque du Soleil mixed circus and theatre and dropped animal acts, so it stopped competing with other circuses.
Use it today: (25 min) List 5 things every competitor offers. Pick one to drop (that buyers don't value) and one nobody offers to add. Write the new offer in one line.

Common mistake: Calling a tiny niche a blue ocean when there's simply no demand.

What it is: Value = (Dream outcome × Perceived likelihood) ÷ (Time delay × Effort and sacrifice).
Coined by: Alex Hormozi, $100M Offers (2021).
Real example: An agency that guarantees a first report in 7 days raises likelihood and cuts time delay without dropping price.
Use it today: (15 min) Score your offer 1–5 on: dream outcome, likelihood, time delay, effort. Improve the lowest one this week. Example: "first report in 7 days" cuts time delay without changing price.

Common mistake: Only raising the dream outcome. Bigger promises without likelihood read as hype.

What it is: Brand building works slowly and broadly; sales activation works fast and narrowly. You need both.
Coined by: Les Binet and Peter Field, The Long and the Short of It (IPA, 2013). They suggest roughly 60% brand, 40% activation as an average, which varies by category.
Real example: A SaaS that only runs bottom-funnel ads sees costs rise as it runs out of people who already know it.
Use it today: (15 min) Look at last month's posts and ads. Mark each B (people will remember us) or A (asks for the sale). All A? Plan one B piece this week, like a useful guide with no pitch.

Common mistake: Treating 60/40 as a fixed law for every business.

What it is: Nine boxes in three phases. Before they buy: target market, message, media. During: lead capture, lead nurture, sales conversion. After: deliver a great experience, increase lifetime value, get referrals.
Coined by: Allan Dib, The 1-Page Marketing Plan (2016).
Real example: A local SEO freelancer: box 1 'clinic owners in Pune', box 3 'Google + WhatsApp', box 9 'ask for a referral on day 30'.
Use it today: (30 min) Fill the blank template below tonight, in order. Any empty box is your next task.

Common mistake: Filling only the 'before' boxes. Most plans die in 'during', with no follow-up.

BEFORE they buy
1. Target market (one job, one place): ____
2. Message (their problem in their words): ____
3. Media (where they already look): ____

DURING
4. Lead capture (form, number, keyword): ____
5. Lead nurture (3 dated follow-ups): ____
6. Sales conversion (one offer, one price, one deadline if real): ____

AFTER
7. First-week experience: ____
8. Increase value (report, upsell, renewal): ____
9. Referrals (ask on day ____): ____

Based on Allan Dib's nine boxes. Write short. One line per box.
