BROWSER-BASED ATTACKS HIT 95% OF ENTERPRISES — AND TRADITIONAL SECURITY TOOLS NEVER SAW THEM COMING

95% of organizations experienced browser-based attacks last year that evaded traditional security tools. Attackers operated inside trusted sessions where web gateways, cloud access brokers, and endpoint protection lose visibility after login. Recent incidents, including ShadyPanda's weaponized extensions and Cyberhaven's supply chain compromise, demonstrate how attackers exploit browser auto-updates and session tokens rather than zero-days. Security leaders recommend inventorying extensions, implementing 48-72 hour auto-update delays, and moving data protection to the browser layer, where 64% of encrypted traffic currently goes uninspected.

NOYB WIN: MICROSOFT ORDERED TO STOP TRACKING SCHOOL CHILDREN

Austria's data protection authority ruled that Microsoft illegally placed tracking cookies on a pupil's device through Microsoft 365 Education, using them to analyse behaviour, collect browser data, and support advertising. The authority ordered Microsoft to stop tracking the child within four weeks and rejected Microsoft's attempt to shift responsibility to its Irish subsidiary.

OXYGEN MONOPOLIES

Fast news cycles and rapid AI adoption mean startups win by owning a clear category narrative early, since attention spikes fast and hardens just as quickly. AI companies now reach $10M+ ARR in under a year, and some hit $100M ARR with fewer than 100 employees, which makes early brand positioning a real competitive advantage. Strong brand association lets one company suck up most of the oxygen, as seen when it becomes shorthand for its category, like Harvey for legal AI. Brand recall now matters more than awareness, since even Tide holds 41% market share but ranks 9th on Amazon search. Companies must make people think of it first or risk being forgotten.

INTRODUCING INVISIBLE ENGAGEMENT AND WHY IT MATTERS

Most consumer interaction with brand content happens through invisible actions that platforms do not track, which makes visible metrics misleading. In a study of 12,855 social media posts, only 0.6% showed visible engagement, while 22.3% showed invisible engagement and 77.1% showed none. The most common invisible actions were ‘see' at 42% and ‘stop' at 41%, which signal attention without public interaction. Posts linked to invisible actions such as ‘see', ‘search', or ‘save' had a higher median shop engagement rate of 10.1% compared to 6.8% for posts that received a ‘like'. These findings show that invisible engagement is more closely tied to purchase behavior and should play a larger role in how marketers measure performance.

4 CTA BUTTON TESTS

Focus on first-person, personalized CTAs that reflect the user's role, interest, or goal, for example, “I want top HR tips” or “Save 25% on my wellness journey”. Use playful or contrasting button pairings, like “I hate learning new things” instead of “Save my seat”. Avoid generic verbs such as “Download” or “Submit”. Replace them with engaging, action-oriented phrases like “Get my discount” or “Let's go!” The goal is to make the CTA feel personal and clearly tied to user benefit.

ASK USERS TO REGISTER AT THE START (NOT THE END)

Asking users to register at the start of shopping increases registrations, purchases, and long-term revenue. In a field experiment of over 75,000 users, early registration made shoppers 58.1% more likely to register and 10.9% more likely to buy. Those shoppers bought 16.8% more items and generated 13.2% higher total revenue over a year. Casual shoppers browsed 12.3% less after early registration prompts. Optional registration prevented short-term sales losses.

HOW DO YOU COMPETE IN AGENTIC COMMERCE?

Agentic commerce is reshaking e-commerce by turning organic search into a verification gate for AI-driven purchases rather than a traffic channel. AI agents powered about 20% of retail sales during the 2025 holiday season, and major platforms now support direct checkout through commerce protocols that bypass traditional websites. Autonomous buying mainly works in a narrow-middle since high-priced purchases resist delegation and low-priced goods already rely on subscriptions, so the real value comes from conversational commerce that compresses an average 14-click journey into 1 or 2 steps. The protocols force merchants to optimize structured product data and APIs instead of pages. As a result, SEO shifts from driving clicks to feeding trusted, granular data into AI systems, favoring incumbents for broad intent and specialists for specific intent.

THERE ARE REASONS TO BE BULLISH ABOUT AI CHAT ADS

AI chat ads could reshape retail media, but their success is uncertain. OpenAI and Google are testing ads in ChatGPT and Gemini, while Amazon and Walmart explore AI-powered shopping. Experts say AI ads could combine strong intent and deep user knowledge, offering personalized experiences if they feel helpful rather than pushy. Retailers want to stay the merchant of record and control logistics, limiting AI's transactional role. Widespread adoption could disrupt retail media by capturing intent and transaction data, but user experience and partner balance remain key challenges.

WHY SEARCH AND SHOPPING ADS STOP SCALING WITHOUT DEMAND

Search and Shopping ads capture existing demand but don't create it. Growth stalls when the audience or queries are limited, not because campaigns are broken. Broad match and AI Max can stretch coverage slightly, but they still rely on search activity. True growth requires creating demand upstream through content, SEO, social, and paid media.

SEEING LIKE A SEDAN

Tesla robotaxis navigate using an array of cameras, while Waymos uses LIDAR technology along with a suite of complementary sensors. Tesla challenged convention, but it has quietly reintroduced radar, and it is possible it may bring in other modalities. The paths for the two companies seem likely to converge in the future. This means that instead of debating whether cameras or LIDAR is better, regulators should be asking whether robotaxis in general are as safe as human drivers.
