OPEN WEB “ALREADY IN RAPID DECLINE” GOOGLE ARGUES IN COURT DOCUMENT

Google argued in a court filing that the open web is already in rapid decline, and a breakup of its ad business would accelerate that trend. It cited AI reshaping ad tech, along with growth in formats like Connected TV and retail media, as reasons ad budgets are shifting away from open-web display advertising. The filing follows concerns about “Google Zero,” the idea that Google search could stop sending traffic to third-party sites, though Google said its AI-enabled search still directs users to a wide range of publishers. WARC data shows online display advertising is stable but growing much more slowly than search and social media advertising.

WE'VE LOST PREVIEW TEXT FOR EMAIL. ARE SUBJECT LINES NEXT?

Apple, Google, and Yahoo are replacing subject lines and preview text with AI-generated summaries, deal cards, and groupings that override brand messaging. These features often misstate discounts, dates, or expirations, eroding trust and damaging customer relationships while removing opportunities for brands to convey personality. Since neither users nor brands can reliably opt out, the changes risk financial loss, legal disputes, and frustration across industries.

IS RELATIONSHIP MARKETING THE NEW MOAT?

With AI tools making automation and personalization widely available, the real differentiator is how brands invest in human connection. Relationship marketing tactics such as handwritten notes, personalized thank you videos, and participation in virtual events help build trust and reciprocity. Combining these with AI-driven analytics allows marketers to tailor follow-ups that mention previous conversations and deliver curated recommendations. These moments of authenticity promote retention and create a durable moat in a commoditized landscape.

5 STEPS TO BUILDING A CONTENT CLUSTER FROM EXISTING CONTENT

Start by identifying 2-5 core parent terms that are high-volume, competitive, and tied to conversion. Audit your content so each URL has one clear target keyword, even if it's not the one you rank for yet. Group related pieces around the parent terms using your ICP knowledge, then validate with SEO tools. Link each page to its parent within the first 100 words and to sibling pages to share authority. Continuously refine clusters as search intent and priorities shift.

WHY THE BEST PRODUCTS TELL MOST PEOPLE TO F*** OFF

Products that polarize users often perform better than those that try to appeal to everyone, as shown by Elden Ring, Linear, Owner, and Superposition, which each deliberately restrict features to serve their core audience. A dedicated 5% of users who love a product is more valuable than 50% who find it acceptable. Founders and marketers can employ this strategy by defining trade-offs, making products act as filters, using complaints as marketing, measuring depth of loyalty rather than width of reach, and doubling down on what makes a product unique.

DO YOU NEED A GTM ENGINEER?

GTM engineers have been (over)hyped as the hottest job of 2025, but hiring is far from widespread. Job postings remain scarce compared to RevOps or SalesOps roles, with many companies instead outsourcing GTM engineering work to agencies or consultants. The role blends system design, automation, and growth experimentation, but sourcing top talent is difficult and often limited to ex-founders or internal transfers. As AI tools become more accessible, companies are training existing teams to handle automation rather than relying on unicorn hires, suggesting GTM engineering may ultimately fold into RevOps and RevTech.

WILL THE ANTI-MONOPOLY RULING CRACK OPEN GOOGLE'S DATA?

Google's antitrust penalties stop short of breaking up its empire but still chip away at its dominance. The company must end exclusive contracts, share portions of its search index and user-interaction data with qualified competitors, and provide syndicated access to search results across verticals. However, it avoided harsher remedies such as divesting Chrome or Android, reinstating Exact Match in ads, or opening up Knowledge Graph data. This article details the implications of each of these decisions in the ruling.
