ON GOOGLE DECLARING WAR ON THE WEB

Google's transition toward AI-generated search results threatens the open internet by replacing direct links to sources with a controlled, proprietary abstraction layer that devalues original human work.

SKECHERS MUST FACE CLASS ACTION OVER MISLEADING PROMOTIONAL EMAILS

Retailers now face real legal risk for using fake urgency in email subject lines, especially in Washington state, where more than 100 brands have already been sued over extended or repeated “limited time” offers. The lawsuit against Skechers shows that brands cannot treat phrases like “Today Only!” or “Ends Tonight” as harmless conversion tactics if the same promotion returns the next day. Brands should align promotional deadlines with actual campaign end dates and audit automated email flows that recycle urgency language across extensions. The court also rejected the argument that extending a sale helps consumers, which signals that intent matters less than whether the messaging creates false scarcity.

EXPEDIA IS PREPARING FOR A FUTURE BEYOND TRAVEL WEBSITES

AI is shifting travel planning from websites to chatbots and assistants, fragmenting how trips are discovered and planned. Expedia is positioning itself less as a consumer site and more as the infrastructure powering bookings. Travelers increasingly use AI for discovery but still prefer established platforms for transactions due to reliable fulfillment when things go wrong.

HOW THE COFOUNDER/CEO OF BEEHIIV RUNS HIS NEWSLETTERS IN MINUTES

This system automates five newsletter workflows. First, an AI editor turns rough drafts into publish-ready copy using a learned writing style and fact checks. Second, a subject line tool uses performance data to improve open rates through tested patterns. Third, an ad copy tool rewrites sponsor content to match voice and optimize clicks. Fourth, automated reports generate weekly branded performance PDFs for advertisers. Fifth, lead gen identifies subscriber employers, scores advertiser fit, and sends qualified leads in Slack daily.

DON'T ASK FOR REVIEWS ON WEEKENDS

Weekday timing matters more than convenience when asking for reviews. Researchers analyzed nearly 400 million reviews across 33 platforms and found weekend reviews scored .04 stars lower on average, while negative detractor reviews increased by 5.7%. Brands that rely on weekend traffic, like restaurants, bars, and hotels, face higher risk because service quality often drops during busy periods. Marketers should schedule review reminder emails during weekdays, lead with positive social proof, and test incentives like loyalty points or discounts since incentives increased review positivity by up to 83.4% in the study.

GOOGLE ASK MAPS: HOW TO OPTIMIZE FOR VISIBILITY

Google Ask Maps changes local SEO from a ranking problem to a recommendation problem, surfacing only 3-8 businesses per query and explaining why each is a fit rather than presenting a long list. The system draws on Google Business Profile data, review language patterns, website content, and external sources to build enough confidence to recommend a business for specific situations. Businesses that rely on generic service descriptions and broad profiles are at a disadvantage, while those with detailed reviews describing specific outcomes and content organized around customer decision-making scenarios are more likely to appear.

HOW TO MAKE CLAUDE BRUTALLY HONEST

This prompt turns Claude into a more rigorous, truth-first assistant that prioritizes accuracy over sounding confident. It avoids fabricating sources or numbers, flags unverified claims, and distinguishes facts from assumptions. It enforces transparency about what is known, unknown, or inferred, requires credible sourcing when possible, and pushes the model to avoid guessing, especially on recent or changing information.

THE FIGMA DESIGN AGENT IS HERE

Figma's new on-canvas design agent can generate multiple landing page or campaign design directions in parallel from a single prompt, then automate bulk edits like swapping components or updating typography across files. For marketing teams without dedicated design resources, the agent handles repetitive production work like converting assets to dark mode and applying brand design systems consistently. It also synthesizes scattered feedback from stakeholders into actionable next steps, reducing the back-and-forth that typically slows campaign delivery.

AI CITATIONS VS MENTIONS: WHAT'S THE DIFFERENCE AND WHAT'S MORE IMPORTANT?

AI visibility depends on two separate systems: mentions, which build brand awareness inside AI models, and citations, which drive referral traffic through linked sources. Mentions come from repeated associations in training data and retrieval, so brands should consistently tie themselves to target descriptors across PR, social, and on-site content. Citations depend on retrieval quality, which means content must rank well, stay fresh, and use tightly focused sections that AI can easily chunk and reuse in answers. Research shows only 13% of brands are both cited and mentioned, and 76.1% of cited URLs are unique to a single AI platform, so you need platform-specific visibility tracking instead of assuming one optimization strategy works everywhere.

TESLA'S NEWEST ELECTRIC VEHICLE COULD JOLT THE TRUCKING INDUSTRY

Early reviews of the Tesla Semi suggest it could be a much-needed hit for the company. It is much less expensive than competing heavy-duty electric trucks and can travel farther. Cost and range are two of the main reasons that many logistics and delivery firms have been reluctant to buy electric trucks. Trucking firms in California have asked the state government for subsidies to help them buy more than 1,200 Tesla trucks, more applications than for all other electric trucks since the state's incentive program began in 2019.

TWO AI-BASED SCIENCE ASSISTANTS SUCCEED WITH DRUG-RETARGETING TASKS

Nature recently released two papers that describe AI systems intended to help scientists develop and test hypotheses. Google's Co-Scientist is designed to keep scientists in the loop, so researchers have to regularly apply their judgment to direct the system. FutureHouse's system can evaluate biological data from specific classes of experiments. Both models are designed to process massive amounts of information to create largely straightforward hypotheses, like whether a drug will work for a specific condition.
