What it is
A growing share of web traffic is not a person with a mouse. It is an AI agent acting on someone's behalf: comparing options, pulling a price, booking a slot, filling a form. Agentic Web Development is building for that visitor. It assumes the reader might be software with a goal, and makes the path to that goal legible.
Why it matters
Agents cannot guess. If your key information is locked inside an image, a script, or an unlabeled button, the agent moves on to a competitor whose site spells things out. Designing for agents tends to make the site better for people and search engines too, because the same clarity helps all three audiences.
What to do
Expose your important data in clean, semantic HTML and structured data. Make actions reachable without hover-only or click-only traps. Where it fits, publish an MCP endpoint so agents can query your site directly.
