Updated on 9 November 2026 by Nicolas Finet, CEO of Sortlist. This guide has been rewritten for 2026: it explains the same eight classic marketing ploys, but now shows where UK consumer law draws the line, since the Digital Markets, Competition and Consumers Act 2024 gave the CMA the power to fine businesses directly.
A marketing ploy is a tactic designed to catch attention, nudge a decision or increase a sale. The word "ploy" suggests trickery, and some tactics deserve the label. Others are simply good retail psychology. The difference usually lies in whether the shopper is helped to make a decision or misled into one. This guide shows eight common ploys, how to spot them and what is allowed in the UK.
Key takeaways
- A marketing ploy is a tactic to draw attention or influence buying behaviour. Many are legitimate; some cross into misleading practice.
- Since 6 April 2025, the CMA can directly investigate and fine businesses up to 10% of global turnover for breaches of UK consumer protection law.
- Fake urgency, misleading discounts, hidden fees and fake reviews are the areas where UK regulators are most active.
What is a marketing ploy?
A marketing ploy is a technique that marketers use to increase awareness and drive purchases of a product or service. It usually draws on psychology: scarcity, social proof, anchoring and convenience. Not every ploy is dishonest. A "limited edition" that really is limited, or a clearly signposted sale, is fair. A ploy becomes a problem when it makes a false claim, hides a material fact or pressures people with invented urgency.
8 most common marketing ploys
| Ploy | How it works | UK risk |
|---|---|---|
| 1. Creating scarcity | "Only 3 left", countdown timers | High if the scarcity or deadline is false |
| 2. Cunning product layout | Placing staples at the back so shoppers pass other products | Low: legitimate retail merchandising |
| 3. Anthropomorphism | Giving products human faces and personalities | Low |
| 4. Large shopping carts | Bigger trolleys make purchases look smaller | Low |
| 5. Pricing logic | Charm pricing (£9.99), anchoring, decoy options | Medium: prices must be clear and complete |
| 6. The Gruen effect | Disorienting store layout that encourages impulse buying | Low |
| 7. False price reductions | Inflated "was" prices before a "sale" | High: misleading price claims are regulated |
| 8. Anti-advertising slogans | "We don't do ads" as a selling point | Low, but claims must still be true |
1. Creating a sense of scarcity
Limited stock and limited time make people act faster. "Only two rooms left at this price" and "offer ends in 10 minutes" are classic examples. Scarcity is honest when it is real: a seat count that reflects actual inventory, or a promotion with a genuine end date.
It becomes a problem when it is fake. The CMA has made urgency claims, which include time-limited claims, countdown timers, "hurry" messaging and other scarcity claims, a focus of its work on harmful online choice architecture, sometimes called dark patterns. If a countdown resets every time the page reloads, it is likely to mislead.
How to spot it: reload the page, check whether the timer resets, and compare the "last items" message across visits.
2. Cunning layout of products
Supermarkets put everyday essentials such as milk and bread towards the back so that shoppers pass through other aisles. They place high-margin items at eye level and impulse buys near the till. Online, the equivalent is "frequently bought together" and recommended products. This is merchandising, not deception, but it is worth knowing before you shop.
3. Anthropomorphism
Brands give products faces, names and personalities, from talking mascots to smiling logos, because people form emotional bonds with human-like characters. It makes a brand easier to remember and trust. The fair-practice test is simple: the character can charm, but the claims it makes still have to be true.
4. Shopping carts of a large size
A widely repeated idea is that bigger trolleys make a basket look emptier and so encourage people to add more. Retailers do pay attention to trolley and basket design, but the headline effects quoted online are rarely backed by transparent research, so treat precise claims with caution. The sensible takeaway for shoppers is practical: take a list, and watch what you add to fill the space.
5. The logic of pricing
- Charm pricing: £9.99 reads as lower than £10.
- Anchoring: a high-priced option next to the one the seller wants you to choose.
- Decoy pricing: a deliberately unattractive middle option that makes the top one look better value.
- Bundling: grouping items so that comparison is harder.
Psychological pricing is legal, but UK law requires prices to be clear. Under the DMCC Act, a trader must not mislead by omitting or hiding material information, and "drip pricing", where mandatory fees appear late in the buying process, is a target of the new rules. The total price should be visible upfront.
6. The Gruen effect
The Gruen effect (or Gruen transfer) is named after the architect Victor Gruen, who designed early shopping malls. It describes the moment a shopper, surrounded by an intentionally confusing layout, loses track of the original purpose of the visit and becomes more susceptible to impulse purchases. Curving paths, no clocks or windows and long routes between entrances and anchors all play a part. It is a feature of the physical environment rather than a false claim, so it is not unlawful, but it explains why a quick trip can become an expensive one.
7. False price reductions
Showing a high "was" price next to a lower "now" price is effective, and UK regulators watch it closely. In August 2024 the CMA updated its guidance on reference pricing. The principle is that a discount must be genuine: the reference price should be the price actually charged before the reduction, for a meaningful period. Retailers previously relied on a rule of thumb of 28 days at the higher price, and the guidance now focuses on whether the claim is truthful in context. A "was" price that was never really charged is likely to mislead.
How to spot it: use a price tracker, check how long a "sale" has run, and compare the same item at other retailers.
8. Anti-advertising slogans
"We don't believe in advertising" is itself a marketing message. It positions the brand as honest and different, and it works with audiences who distrust ads. Such statements still need to be accurate: a brand that claims not to advertise while buying paid media or paying influencers is exposed to criticism and, in some cases, to complaints about misleading claims.
Advantages and disadvantages of marketing ploys
Advantages
- They capture attention in crowded markets.
- They can help customers decide, for example by highlighting a genuine deadline.
- Honest ploys build memorability and brand personality.
Disadvantages
- They damage trust when customers feel tricked.
- Misleading tactics can lead to complaints to the ASA, enforcement by the CMA and trading standards, and fines up to 10% of global turnover for serious breaches.
- Over-use of urgency can train customers to ignore all your messages.
What the law now says in the UK
“From 6 April, the CMA will be able to directly investigate and enforce consumer laws, including the new power to impose fines of up to 10% of global turnover for breach of consumer protection laws.”
CMS law firm, The DMCC Act consumer elements come into force
- Fake reviews and hidden fees are among the practices addressed by the DMCC Act regime.
- Some practices are banned outright as automatically unfair, so no case-by-case defence is available.
- Criminal liability: certain breaches of the unfair commercial practices rules are criminal offences, according to CMA guidance.
This is a general summary, not legal advice. Check the CMA's unfair commercial practices guidance or consult a solicitor before you run a high-risk tactic. For labelling rules on paid content, see advertorials and UK rules and UK ad complaints.
Marketing ploys across different media
- In-store: layout, signage, sampling and placement.
- Online: countdown timers, "low stock" badges, personalised recommendations, pop-ups.
- Email and SMS: "last chance" messages and abandoned-basket reminders.
- Social media: influencer promotions, limited drops and user-generated content, all of which must be labelled as ads where paid.
- Advertising: comparisons and claims; see comparative advertising.
Summing up: what makes a good marketing ploy?
A good ploy is truthful, easy to verify and useful to the customer. It brings attention to a real benefit, a real deadline or a real price, and does not depend on the shopper missing something. A tactic that only works if the customer does not look closely is a risk to your brand and, in the UK, to your finances.
