Search stopped being ten blue links
A buyer researching vendors now opens ChatGPT or Perplexity, or reads the AI summary at the top of Google, before they ever land on your site. Often they never land on it at all. They get an answer, form an opinion, and shortlist from there.
Those engines do not read a page the way a person does. They extract. They want clear facts they can attribute to a source, and they favor pages that make those facts easy to find.
Most marketing sites give them almost nothing to work with. The strongest claims are baked into images. The real answers are in a video. The structured data, if there is any, is injected by JavaScript after the page loads.
Most AI crawlers do not execute JavaScript. If your structured data arrives after the page does, the engines you are trying to reach never see it.
That single detail disqualifies a lot of otherwise well built sites, and almost nobody checks it.
