Summary: Google's Guide explains Google. However, ChatGPT, Claude, and Perplexity still require their own evaluation.<\/p>\n\n\n\n
In May 2026, Google published an official guide on how to optimize websites for Google Search\u2019s generative AI features: \u201eOptimizing your website for generative AI features on Google Search.\u201c The reaction in many SEO circles was immediate: \u201eAI optimization is just SEO. Case closed.\u201c<\/p>\n\n\n\n
This interpretation is too broad. It turns a Google guideline into a rule for all AI systems. Google\u2019s guide applies to Google. In the provider documentation from OpenAI, Anthropic, and Perplexity that I reviewed on July 11, 2026, I found no comparable guidance on which content to cite or which brands to recommend\u2014but I did find crawler documentation and external metrics. This shifts the focus of the question: It\u2019s not just about implementation, but about measurement.<\/p>\n\n\n\n\n\n
The guide is remarkably clear. Google updated it on July 10, 2026. Three key points remained unchanged; in the original:<\/p>\n\n\n\n
First: No special AI files are required.<\/strong><\/p>\n\n\n\n \u201eYou don't need to create new machine-readable files, AI text files, markup, or Markdown to appear in Google Search. Doing so will neither harm nor help your site's visibility or rankings in Google Search.\u201c<\/p><\/blockquote>\n\n\n\n This includes llms.txt. The file has neither a positive nor a negative impact on Google search results.<\/p>\n\n\n\n Second: no specific schema pushing.<\/strong><\/p>\n\n\n\n \u201eStructured data isn't required for generative AI search, and there's no special schema.org markup you need to add.\u201c<\/p><\/blockquote>\n\n\n\n Structured data is still recommended as part of general SEO efforts\u2014but there is no secret AI markup that forces citations.<\/p>\n\n\n\n Third: AI optimization is SEO.<\/strong><\/p>\n\n\n\n \u201eOptimizing for generative AI search means optimizing for the search experience, and therefore it's still SEO.\u201c<\/p><\/blockquote>\n\n\n\n Anyone with solid SEO fundamentals\u2014crawlable content, visible text, a clear structure, and up-to-date data\u2014has, from Google's perspective, done what is required for AI Overviews and AI Mode.<\/p>\n\n\n\n New as of July 10: Google is expanding its metrics.<\/strong> The guide now refers to a \u201eGenerative AI performance report\u201c in Search Console. The report is intended to show how content is found via Google\u2019s generative features in Search and Discover. This is a significant change from the July 3 version\u2014and it also confirms the platform\u2019s limitations: Google measures Google. This report provides no information regarding ChatGPT, Claude, or Perplexity.<\/p>\n\n\n\n This is a useful guide with a clearly defined scope: on Google Search<\/em>. The guide describes how Google populates its own AI features. It says nothing about how ChatGPT, Claude, or Perplexity decide which sources to cite and which brands to recommend.<\/p>\n\n\n\n OpenAI, Anthropic, and Perplexity document their crawlers\u2014which bots are out there and how website operators can control access. I did not find any official guidelines on how content is cited in responses or how brands are recommended in the provider documentation I reviewed on July 11, 2026.<\/p>\n\n\n\n But that doesn't mean we know nothing about these platforms. It just means that the information comes from a different source: from measurements by SEO and AI visibility providers who analyze AI responses and citations in larger datasets. Their findings apply only to the specific platforms, time periods, and methods examined.<\/p>\n\n\n\n Four findings, each with a sample size, platform, and time period\u2014because a number without this context is misquoted:<\/p>\n\n\n\n Two things stand out. First: The individual technical signals that have long been the focus of the GEO discourse\u2014llms.txt and Schema markup\u2014do not provide a reliable citation lever in these measurements. Google explicitly states this for its own search; SE Ranking, ALLMO, and Ahrefs also see no positive effect in their respective datasets. Second: It does not follow from this that a single editorial or reputation-related factor influences citations caused<\/em>. Google recommends unique, non-interchangeable content for Google. ConvertMate reports a strong correlation with brand mentions. Both are approaches, not guarantees of results.<\/p>\n\n\n\n It is important to note the limitations of the data: The studies evaluate different platforms using different methods. Taken together, they paint a consistent picture, but no single finding automatically applies to all AI systems.<\/p>\n\n\n\n The practical difference is simpler:<\/p>\n\n\n\n One Platform Guide<\/strong> basically says what everyone should do: make content crawlable, keep data up to date, and avoid producing interchangeable filler content. That's valuable, but it only answers the question: What does this platform generally recommend?<\/em><\/p>\n\n\n\n A Audit<\/strong> Examine the specific case: Is this website mentioned by ChatGPT, Claude, Perplexity, and Google AI? Is it understood correctly? Which sources shape the picture? Which competitors appear instead?<\/p>\n\n\n\n In short: The guidelines describe the target state. The audit reveals the actual state.<\/p>\n\n\n\n Both have their place. Google\u2019s Guide is the authoritative reference for Google\u2014anyone who contradicts it needs very solid data. But anyone who concludes from \u201eAI Optimization is SEO\u201c that measurement is unnecessary is confusing the user manual with the status report. Two websites can fully comply with the same guide and yet appear completely differently in AI responses\u2014because reputation, source reliability, and entity clarity cannot be determined by a checklist alone.<\/p>\n\n\n\n For a WordPress site, this means:<\/p>\n\n\n\n If you want to see the current state of your website, the AI Visibility Audit with citelayer\u00ae<\/a> In addition: multiple platforms, competitors, source analysis, prioritized next steps.<\/p>\n\n\n\n The short version: Google explains Google. You have to measure your own AI visibility.<\/p>\n\n\n\n Verified again on July 11, 2026:<\/strong><\/p>\n\n\n\n Internal Links (AI Visibility 2026 Series, all published on June 18\u201319, 2026):<\/strong><\/p>\n\n\n\n Kurzfassung: Googles Guide erkl\u00e4rt Google.
