Campaigns no longer face a blanket Claude ban on personalized vote targeting, and journalism exits the high-risk list. What else changes for brands from today?

AI referrals versus Google is a fair comparison of two streams feeding a smaller pool, and agents that complete the purchase are where the offset starts.

Bing is showing third-party website ratings, including ratings sourced from Bizrate, within its sponsored search results.

Microsoft Advertising announces UI improvements addressing advertiser feedback, including easier navigation, expanded reporting, sign-in troubleshooting, and account access management.

Data shows visits to the world's top million websites declined from an earlier peak, visits going to sites outside the top 100 barely changed.

Agent plugins are installable bundles of skills, connectors, commands, subagents and hooks that extend AI agents such as Claude Code, Cowork and OpenAI's Codex.

Agent skills are folders of instructions, scripts and files, built around a SKILL.md file, that AI agents load only when a task needs specialised know-how.

A system prompt is the standing instruction set a developer gives a language model before any user speaks. How it works, why it leaks, and its role in AI ads.

A context window is the maximum number of tokens an AI model can consider in a single request. How windows are counted, filled, compacted and why they degrade.

Tool calling is how a large language model asks software to run a named function with structured arguments, letting AI agents query data and act elsewhere.

An agent team is a group of AI agents that split one goal into tasks, claim work from a shared list and message each other directly, usually under a lead agent.

Agent2Agent Protocol (A2A) is an open standard that lets AI agents from different vendors discover each other, delegate tasks and exchange results over HTTP.

Session isolation keeps each AI agent session's compute, memory, files and credentials walled off from others, so one client's task cannot leak into another.

LION Publishers barely broke even on its 400-person summits in 2025 and 2026, and OpenNews entered emergency mode. SRCCON and INN Days 2027 remain undecided.

Up to 10 open tabs, retailers' product pages included, can feed Gemini's answers in Chrome's side panel. Can sellers see what shoppers ask about their products?

Third-party programmatic ads get no automatic AI label, and video sites without the IMA SDK must add icon support. Who now owes each AI disclosure, and where?
