Brand & Creative Effectiveness

Myth:Performance marketing should get the majority of budget.

Evidence:Across hundreds of IPA case studies, roughly 60% brand / 40% activation maximises long-term profit growth in consumer categories.

Myth:TV's ROI estimates justify current spend levels.

Evidence:Estimating elasticities and ROI across 288 brands, Shapiro, Hitsch & Tuchman find ad elasticities far smaller than the published literature suggests, negative ROI at the margin for more than 80% of brands, and positive overall ROI for only about a third.

Myth:If ads don't move this week's sales, they didn't work.

Evidence:Across 751 short-term and 402 long-term elasticities from 56 studies (1960-2008), the average short-term advertising elasticity is 0.12 - but the mean long-term elasticity is 0.24, double the short-term, through carryover.

Myth:Loyal heavy buyers are the growth engine.

Evidence:Brand growth comes overwhelmingly from increasing penetration among light and non-buyers, not from deepening loyalty.

Myth:Targeting and media buying determine campaign outcomes.

Evidence:Creative quality accounts for roughly half of advertising-driven sales variance — a larger share than any single media variable.

Myth:Outspending competitors on media weight lifts sales.

Evidence:Across 389 BehaviorScan split-cable TV experiments, increasing budget relative to competitors did not increase sales in general - changing brand, copy, or media strategy did. Standard recall and persuasion pretests did not predict which ads would move sales.

Myth:Rational product messaging drives the strongest results.

Evidence:Emotionally led campaigns produce roughly twice the long-term business effects of rational ones, and the gap widens with campaign duration.

Myth:Likes are the signal that drives distribution.

Evidence:LinkedIn's own ranking model uses a dwell-time prediction weighted independently of — and more heavily than — likes, with no fixed second threshold. Content that gets read all the way through outranks content that gets tapped and skipped.

Myth:Award-winning creativity is automatically more effective.

Evidence:Across nearly 600 IPA Effectiveness Award case studies (1996-2018), creatively awarded campaigns have fallen to their lowest effectiveness in 24 years of analysis and are now no more effective than non-awarded campaigns; short-termism is the main driver.

Myth:Cut ad spend first when a downturn hits.

Evidence:The IPA's recession evidence review finds brands that maintain share of voice through a downturn recover faster and gain share over cutters - cutting spend mortgages the recovery.

Myth:B2B growth comes from persuading buyers with superior messaging.

Evidence:Ehrenberg-Bass research shows B2B buyers start from a mental shortlist built from category entry points - the cues (motives, situations, occasions) that retrieve brands from memory. Brands grow by linking themselves to more CEPs, not by winning rational arguments.

Myth:Creative quality alone determines effectiveness.

Evidence:Comparing 4,863 effectiveness award cases (2011-2019), the largest business effects came from 'creatively committed' campaigns: more media spend, more channels, and longer durations behind one creative platform - captured in the Creative Effectiveness Ladder.

Myth:Rotate creative constantly - ads wear out fast.

Evidence:The ARF's evidence review finds true creative wear-out is less common than assumed: repeated exposure more often builds memory (wear-in) than fatigue, and marketers tire of their ads long before consumers do.

Myth:Small brands can win by being unusually loyal.

Evidence:Double jeopardy: smaller brands have both fewer buyers and slightly lower loyalty — an empirical law observed across categories and decades.

Myth:Viewability equals attention.

Evidence:Viewability is a necessary floor, not a measure of attention; attention-time metrics predict brand outcomes far better than viewable-impression counts.

Myth:A safe, neutral ad just works a little less hard.

Evidence:Modelling IPA cases with System1 emotional-response data, 'dull' low-emotion TV ads need far more media to match effective creative: roughly 10m pounds extra per UK campaign, scaling to an estimated $228bn of extra spend across US TV to match the market-share growth of the most impactful spots.

Myth:Tight, information-dense ads are the efficient choice.

Evidence:Broad, character-led, 'right-brain' creative correlates with far larger long-term effects than narrow message-dense executions.

Myth:The more personal an AI-generated ad looks, the better it will work.

Evidence:In a 100-person within-subject study across four products, moderately personalized AI imagery earned the best ad and product attitudes. At high personalization, rising creepiness outweighed the relevance benefit and neutralized gains across ad attitude, product attitude, and purchase intent.

Myth:B2B buyers decide on business value: ROI, specs, risk.

Evidence:In Google/CEB/Motista research, B2B purchasers were almost 50% more likely to buy when they saw personal value (career advancement, confidence, pride) in the decision and 8x more likely to pay a premium; only 14% would pay a premium for perceived business-value differences.

Myth:CTV attention is no better than feed scrolling.

Evidence:In the first industry-endorsed attention study, streaming video ads held almost 80% attentive viewing with minimal drop-off over time - 123% more attentive viewing than scrollable social (Amplified x Video Futures Collective, 2025).

Myth:Brand tracking surveys are the only forward indicator.

Evidence:Share of search leads market share by several months in many categories, giving a cheap, high-frequency brand-health proxy.

Myth:Every campaign needs a fresh creative idea.

Evidence:Recurring fluent devices and consistent assets build recognition faster and cheaper than continually restarting creative platforms.

Myth:The link penalty is a LinkedIn-only quirk.

Evidence:It replicates across networks. Sprout Social's LinkedIn test recorded 8,136 impressions for link-in-comment posts vs 3,309 with the link in the body (261 vs 141 engagements). Socialinsider's analysis of 51,054,216 Facebook posts found body links roughly halve engagement potential, and Hootsuite's linkless-tweet experiment found 56% of its top-engaging tweets contained no link.

Myth:AI-generated ads are too crude to tell you anything about the real spot.

Evidence:In a peer-reviewed proof-of-concept, AI-generated static and video pretest ads scored statistically indistinguishable from the real finished ads they were based on - recall, recognition, brand choice, brand attitude, ad liking.

Myth:Refresh the brand identity every few years to stay modern.

Evidence:Identity resets discard accumulated distinctive-asset memory; evolution beats revolution unless the brand carries active negative equity.

Myth:A viral brand video can substitute for paid reach.

Evidence:Analysis of branded video sharing shows high-arousal emotional content is what gets shared, yet sharing rates stay low even for strong creative - so earned views are a bonus on top of planned reach, not a channel.

Myth:Ads only work when the copy states product facts.

Evidence:In an incentivized experiment with randomized exposure, content, and price, display ads shifted beliefs about price and quality even when the copy revealed neither - and those belief shifts causally drove search and purchase.
