Content for people

Google's repeated message is to optimise for people: it asks for unique perspectives and expertise beyond common knowledge, says content made for Search will not succeed, and calls optimising for people optimising for generative AI Search. Day 2 tied this to indexing: Google said index selection aims to keep only documents useful now or later, that page quality ultimately decides indexing, and that 'Crawled – currently not indexed' is most often a quality issue rather than a technical one (the index-selection details were said at the event, not in Google's docs). Google repeated Day 1's advice to focus on users, saying that creating content users like is a better use of time than combing documentation for signals, and Google said both retrieval methods work from page content, so the content mantra of about 25 years still stands. Google's video talk added that paying for a generative AI subscription does not make AI-generated videos succeed. Day 3 made content quality central to ranking: Google's quality talk defined it, as the rater guidelines do, by effort, originality, talent or skill and accuracy, contrasted commodity content built on common knowledge with unique, experienced takes, and said quality problems are quality issues, not AI versus human ones. Google added that pages need no synonym lists, because Google expands queries itself, and its guidance names writing to a word count or covering many topics in the hope of traffic as signs of search-engine-first content. Google's marketing research talk reached the same advice, optimise for people because a human makes the final decision, and the closing talk warned that chasing fan-out queries distracts from creating helpful content. A community case study, in which a niche article drew 28 times more clicks than a comprehensive one from far fewer impressions (no data source or period given), illustrated the point. A second recording of Day 1 added that the opening keynote closed with 'UEO', user engine optimisation, next to SEO and GEO: focus on the user and the rest will follow; it also said high-quality content may be created by humans or by AI, as long as it is made for users and not for search, and that information quality remains a core focus across Search, YouTube and Discover. Cherry Prommawin said quality is one of the most important things in ranking, and Gary Illyes said the natural content Google's algorithms understand and promote better includes content created, or at least edited and reviewed, by humans (said at the event). A Google host of the AI lightning talks advised always checking what AI tools do and focusing on what the business and its users need, and on Day 2 Gary Illyes said AI-generated images and videos must be checked for hallucinations. In Day 2's consolidation case study a community speaker kept only pages with real business potential, introduced the financial experts responsible for the content instead of an anonymous content factory, and credited the growth to quality rather than more content.

What to do

  • Prioritise unique expertise and first-hand experience over covering every possible need.
  • Treat 'Crawled – currently not indexed' as a quality audit list: compare those URLs with indexed pages of the same type before hunting for technical faults.
  • Put the terms a page should rank for in its main content and explain the topic fully in plain words, without keyword stuffing.
  • Do not rewrite content into chunks or AI phrasing; write for readers.
  • Judge every article, AI-assisted or not, by the effort, originality, skill and accuracy it adds beyond what an LLM would answer directly.
  • Start content briefs from a concrete problem a real group of users has, and judge articles by clicks and conversions, not impressions.
  • For reviews, test the products yourself and publish your own photos, measurements and test method.
  • Show the real experts responsible for what the site publishes, especially on financial or other high-stakes topics.

  9. Stage D2-C714 Day 2 · Deciding what goes in the index?
