Designing for machine readers
A growing share of the people who meet your brand will never see it. They will read a summary a model wrote. That is a design problem.
There is a version of your company that exists only in the answers assistants give about it. Someone asks what your firm does, and a model answers from whatever it extracted from your website. That answer is a brand surface. Nobody art-directed it.
The plumbing is the design
Markup carries meaning, and we have been sloppy about it because the consequences used to be invisible.
- A heading that is a
divwith a large font size is meaningless to a parser. - Metadata that lives only in a styled sidebar is ambiguous to everything but a human.
- A page that renders after hydration is, to most crawlers, an empty page.
None of these are hard. They are just decisions that have to be made on purpose.
What actually helps
- Ship complete HTML. If content only exists after JavaScript runs, assume machine readers never see it.
- Use a real heading hierarchy. One
h1, descending without skips. Free, and the strongest structural signal there is. - Say the important thing first. Models weight early, self-contained statements. A paragraph that only makes sense after three others gets quoted badly or not at all.
- Be consistent about entities. Same name, same one-line description, everywhere. Writerly variation reads as ambiguity to a system trying to resolve who you are.
- Add structured data. Boring, and it states unambiguously what a page is rather than leaving it to inference.
- Answer questions in question shape. If clients ask how fast you work, make that the heading.
The uncertain part
Much of what is sold as AI optimisation is folklore. Conventions like llms.txt are cheap and reasonable in principle, but public evidence that major systems consume them is thin — anyone claiming otherwise with confidence is guessing.
What is not uncertain is the discipline underneath. Clean semantics, complete HTML, honest structure and clear writing have been the right answer for accessibility for twenty-five years. They are the right answer for search. They happen to be the right answer for machine readers too.
The audience changed. The craft did not.
