Voice search optimisation means structuring content to answer the longer, more conversational questions people ask assistants like Google Assistant or Siri, rather than the short, fragmented phrases typed into a search box. Because voice searches skew heavily local and question-based, it overlaps closely with Answer Engine Optimisation - concise, direct answers, question-phrased headings, and accurate local details all matter more than traditional keyword density.
Voice search queries read differently to typed ones - longer, more conversational, and more likely to include local intent. Optimising for them has more in common with Answer Engine Optimisation than with traditional keyword-focused SEO.
Why voice queries are structured differently
Someone typing a search tends to shorten it out of habit - "plumber Christchurch." Someone speaking to an assistant tends to ask the full, natural question - "who's a good plumber near me in Christchurch." Content built to directly answer the natural-language version of a question is far more likely to be the source an assistant reads from.
Local intent is baked into most voice searches
A large share of voice searches carry local intent, whether stated explicitly ("near me") or implied through the device's own location. This makes the same fundamentals that drive normal local SEO - a complete Google Business Profile, accurate service area, consistent citations - just as relevant to voice results as they are to the standard map pack.
Structure content to be read aloud
An assistant reading a result aloud needs a clean, self-contained answer, not a paragraph buried in context. Leading with a direct answer to the obvious question, in plain language, gives both the assistant and a human reader exactly what they're looking for without extra effort.
FAQPage and Speakable schema help
Neither guarantees a voice result, but both give assistants an unambiguous, structured piece of content to pull from rather than requiring them to interpret unstructured prose. FAQPage schema marks up clear question-and-answer pairs; Speakable schema flags the specific sections most suited to being read aloud.
Measuring voice search is indirect
Most analytics tools don't separate voice traffic from typed traffic, since the resulting click looks identical either way. The better proxy is whether your content is already winning featured snippets and "People Also Ask" boxes, since those are the formats most voice assistants read from directly.
