Optimising content for AI Search: a step by step guide

Bùi Quốc Phương Nam

Google increasingly rewards content that machines can parse. This guide covers how to optimise a page so it both ranks in classic search and gets picked up as a citation by AI assistants.

Why classic SEO is no longer enough

A page used to need the right keywords, enough backlinks and acceptable load times to compete. Today most long tail queries are answered on the results page itself, or inside an AI assistant, so your page has to be chosen as a source before it earns an impression.

Three shifts in search behaviour

  • Queries are longer and conversational rather than a handful of loose keywords.
  • Readers scan the summary first and only click through to a source when they need detail.
  • Language models favour content with clear structure and verifiable figures.

Content that works well for AI is content that works well for people: clear, structured, and answering the question directly.

Structuring an article for citation

The biggest difference between an article that gets cited and one that is skipped is structure. Each section should stand on its own as a complete answer.

Lead every section with the answer

Write a 40 to 60 word paragraph directly under each heading that answers the question the heading poses. Put the explanation, examples and figures after it. This lets a language model lift the right passage without having to infer it.

Give every heading an anchor

Each heading should carry its own id attribute so any section can be linked directly. This is a required criterion in the SERPUPDATE scoring set, and it is also how AI tools cite a precise passage rather than a whole page.

Seven technical signals to check

The items below affect crawlability and citation directly.

Quick checklist

Signal Target Applies to Weight How to verify Common mistake
Page title length 10 to 60 characters Every page High View source, check the title tag Reusing one title across a template
Meta description length 50 to 160 characters Every page Medium Search console coverage report Leaving it for the engine to invent
Single H1 per page Exactly one Every page High Heading outline audit Wrapping the logo in an H1
Heading anchors At least 30 percent carry an id Content pages High Inspect heading attributes Anchors dropped by the editor

Measuring the result

After applying the changes, track two families of metric side by side: keyword position in classic search, and how often the page is named in assistant answers. They do not always move together, and the gap tells you which signal is missing.

A sensible review cycle

Review content pages every 90 days. Refresh the figures, fill the gaps and record the modification date. Content older than 90 days without an update loses points in the trust group of criteria.

To score any address against all 128 criteria at once, run it through the SERPUPDATE checker and read the report group by group.
