LinkedIn now lets you set post URLs
The newsletter reports two actionable shifts for marketers: ChatGPT has reprioritized official websites when answering queries, causing Reddit citations to plunge (reported drop from 3.8% to 0.5%), which increases the importance of brand-owned pages (pricing, competitor comparisons, and succinct FAQs) for being cited by AI. Separately, LinkedIn constructs post URLs from the first line of text by default but provides a hidden option to override and set a custom URL — a small, free change that can improve search and AI discoverability. The author links to an AEO playbook and data supporting these observations.
Changes in how generative AI sources answers (favoring official pages) plus LinkedIn allowing custom post URLs affect SEO, AI discoverability, and content strategy — relevant to marketers and publishers but not industry-shifting.

LinkedIn's AI Changes Content Distribution
LinkedIn has redeployed its feed-distribution logic to prioritize content quality and author expertise using an AI system called 360Brew (reported as a 150‑billion‑parameter model). The platform now weights different engagement signals differently (research cited in the article says a save boosts reach far more than a like and increases follow probability), and LinkedIn’s AI evaluates the text and an account’s topical consistency rather than relying primarily on raw engagement metrics. Third‑party tracking (AuthoredUp) across hundreds of thousands of posts shows most users have seen reach declines since the change, creating a temporary window where publishers who adapt early can gain advantage. The article outlines tactical advice for creators — lead with expertise, narrow topic territory, and reply to comments — to work with the new distribution model.
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At DMEXCO 2026, Céline Flores Willers, founder of The People Branding Company, argued that B2B marketing often appears outdated due to fear of innovation (FOMU).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.
