Optimized Subtitles Can 5× Your Viral Chance
A Marketing Ideas newsletter article (published 2026-05-18) argues that well-designed burned-in subtitles dramatically increase the chance short-form videos go viral because many viewers watch on mute. Citing a tweet from Nikita Bier (Head of Product at X) about muted viewing, the author presents six practical subtitle best practices: lock the first subtitle on screen at second 0, keep the first line under six words, disable platform auto-captions on upload, enlarge key words or numbers, add contrast/backgrounds for readability, and position text within the vertical middle 60% 'safe zone' to avoid UI overlays. The piece is sponsored by Brew and notes Brew integrates with common ESPs (Klaviyo, HubSpot, Mailchimp). The advice targets creators and marketers optimizing social video performance across platforms like X, LinkedIn, TikTok and Instagram.
Practical creative guidance for social video and creators; useful for optimizing engagement but not a platform-level or industry-changing development.

Inaccessible Advertising Lowers Campaign Performance
An industry opinion piece explains how treating accessibility (especially subtitles/captions) as an afterthought is creating measurable underperformance in video advertising across mobile, social and connected TV. Citing XR Extreme Reach research, the article highlights rising subtitle-native viewing habits—particularly among younger audiences—and reports that subtitles increase attention and engagement with ads. Despite this, roughly half of UK ads lack subtitles. The author argues accessibility should be integrated into creative production, campaign infrastructure and measurement, not siloed as a compliance task, because subtitle-first viewing behavior changes how audiences consume and understand advertising and therefore affects media efficiency and creative effectiveness.
Céline Flores Willers urges B2B marketers to think like B2C
At DMEXCO 2026, Céline Flores Willers, founder of The People Branding Company, argued that B2B marketing often appears outdated due to fear of innovation (FOMU). She demonstrated creative tactics like using a robot sidekick 'Robi' and branded T-shirts to boost attention and branding. She highlighted LinkedIn as the central platform for B2B, citing a SAP Taulia case where employee-generated content, boosted via Thought Leader Ads, achieved 2.3x higher engagement and 70% higher click-through rates with a small budget. Willers also cited examples like Legora's campaign with Jude Law and Merz Lifecare's 25-post merger documentation as successful 'building in public' strategies. She concluded by urging B2B marketers to be more creative and learn from B2C approaches.
LinkedIn says don't treat leads as finish in B2B
At LinkedIn's B2Believe event in its new Empire State Building space, executives and practitioners called for a shift from lead-centric B2B marketing to a 'full journey' approach that links signals, targeting, creative, full journey, and measurement. Jae Oh, senior director of product management, revealed that fewer than 10% of upper-funnel audiences make it into bottom-funnel campaigns, urging marketers to connect awareness with demand capture. Research from LinkedIn's B2B Institute with eMarketer showed 77% of marketers say they no longer target individuals, yet only 31% have a playbook for activating audiences down the funnel. Practitioners from Canva, SAP, Mastercard, and others shared examples of aligning marketing and sales on common signals. LinkedIn also outlined a product roadmap focused on cost-per-opportunity targeting, multi-format campaigns, agentic workflows, and incrementality forecasting.
