This is the most expensive mistake for tech startups right now, and nobody's talking about it. Your landing page has two visitors now. One is human. One is an agent, quietly reading your site's structure before any human sees it. This isn't a slow trend. It happened in the last few months, and most B2B startups haven't caught up. Agents don't decide like people do. They research, compare, and shortlist vendors before a human looks at anything. The agent reads your site. Decides if you're credible. Tells the human what to trust. If that agent can't parse your site, it doesn't reject you. It just doesn't mention you in the shortlist it hands back. The real challenge for founders right now isn't a redesign that looks better. It's a redesign that works equally well for humans and agents.
