What is answer engine optimisation?

The term describes a real change and is often used loosely, so it is worth defining tightly. Answer engine optimisation is the practice of making a page usable as a source by systems that answer a question directly rather than returning a list of destinations. The output being competed for is a citation and an extracted passage, not a click on a ranked result.

It is a separate contest from search optimisation and the evidence for that separation is specific: only around a tenth of sources cited in generated answers also appear in the organic top ten for the same query. The two overlap in their foundations — a page must be reachable and readable to be either ranked or cited — and they diverge sharply in what wins. A page can rank well and never be cited, and be cited routinely while ranking nowhere.

What the practice consists of is unglamorous and short. Answer the question completely in the opening sentences, because extraction operates on passages rather than pages. Attach a source and a date to every figure, because attribution travels with an extracted passage and makes it safer to reuse. Include at least one sentence written to be quoted verbatim. Publish something that exists nowhere else, because redundancy suppression means a restatement of common knowledge gives a system no reason to reach for your version. And structure the site so related entities link to each other, so a retrieval system can follow relationships rather than infer them.

What it is not is a technical configuration. Markup helps a machine parse what is present and cannot create something worth citing, and a page with immaculate structured data and nothing distinctive on it is well described and still not worth quoting. The order is content first, structure second, and reversing it produces effort with no result.

The reason it matters now rather than eventually is the volume shift. A large majority of searches already end without a click, and where a generated overview is present organic click-through falls to roughly a third of what it is otherwise. A business optimising exclusively for position is competing for a share of a shrinking quantity while the growing one is decided elsewhere.

One consequence worth internalising: the same properties that make a page citable also make it resistant to being replaced by the answer. A page whose value is a single number will be quoted and made unnecessary. A page whose value is that four published figures are not comparable, and why, cannot be compressed into an overview without the overview being wrong. Publishing toward the second kind is both the citation strategy and the defence against it.
