• How to Separate Human Visitors From AI Agent Traffic in Website AnalyticsAI agent traffic comes in three forms that look very different in analytics. Here is how to identify each, where the data lives, and what cannot be separated cleanly.
• How to Design a Website for Both Humans and Autonomous BrowsersHow to design one website for both people and autonomous browsers: semantic structure, predictable interactions, server-rendered content, safe actions, honest content and a 30-day plan.
• How to Create Machine-Readable Policies for AI AgentsHow to publish site policies AI agents can read: robots.txt and content signals for crawling, structured data for returns and shipping, and clear human-readable terms.
• How to Build an Agent-Friendly Checkout PageHow to build a checkout page that agents and people can both finish: semantic fields, predictable steps, clear totals, safe confirmation and the protocol options emerging in 2026.
• How Product Feeds Need to Change for AI Shopping AgentsHow to update product feeds for AI shopping assistants: descriptive titles, richer attributes, consistent structured data, and price and stock that stay fresh.
• AI-Friendly Forms Explained: Designing Web Forms That Agents Can Complete ReliablyHow to design web forms that AI agents and people can both finish: real labels, autocomplete, native controls, specific errors and a simple testing routine.
• AI Sales Agents in CRM Explained: What They Can Automate Beyond ChatAI sales agents inside a CRM do far more than answer questions. What they can automate today, where they still need people, and how to test one safely.
• AI Recruiting Agents Explained: Screening, Scheduling, and Candidate CommunicationWhat AI recruiting agents do in screening, scheduling and candidate messages, the bias and legal risks, and how to use them fairly as an employer or applicant.

• AI Agent Rollback Explained: How to Undo an Autonomous MistakeRollback for AI agents isn't one thing — it's three different undo mechanisms with very different reliability. Here's how each works and how to know which one an action actually needs.
• AI Agent Permissions for Websites: What a Site Should Let Bots DoA risk-based way to decide which actions AI agents may take on your website, from reading pages to placing orders, with scoped access, confirmations and rate limits.

• AI Agent Task Receipts Explained: A Better Record of Autonomous ActionsA task receipt compresses an AI agent's full execution trace into what a human actually needs to verify the action was correct. Here's what belongs on one and why it shouldn't replace full traces.
