That line is Google-Extended, and it is real, but it does both less and more than most people assume. It will not pull you out of the AI Overviews at the top of Search, and it has zero effect on your rankings. What it actually controls is narrower, and worth understanding before you copy a rule off a forum. Here is exactly what Google-Extended does, what it does not, and how to set it on a WordPress site. Table Of Contents ## What Google-Extended actually is Google introduced Google-Extended as a control for publishers. It governs whether the content Google crawls from your site may be used to train future generations of the Gemini models that power Gemini Apps and the Vertex AI API, and for grounding in those products. One detail trips almost everyone up: Google-Extended is not a separate crawler. In Google's own words it is a standalone product token with no separate request user agent, crawling is still done with existing Google user agents, and the robots.txt token is used in a control capacity. So you are not blocking a bot that visits your site. You are setting a flag that tells Google how it may use what it already crawls for Search. ![Google documentation describing the Google-Extended crawler token](https://theplusaddons.com/wp-content/uploads/2026/07/C8ZDCs45gjF4geT4BPTIEMbBlSJjWlwkVkYSUG4q7n5TWxznb9qGZlc_NY7VfzboDXCdTLhaB8f5dfGSatsuXg-scaled.png)Google's own documentation describes Google-Extended as a standalone product token. Source: Google. ## What Google-Extended does not do There are two limits worth stating plainly. First, straight from Google: Google-Extended does not impact a site's inclusion in Google Search, nor is it used as a ranking signal. Blocking it costs you nothing in Search. Second, and this is the part that surprises people, blocking Google-Extended does not remove you from AI Overviews or AI Mode. Those AI answers inside Search are built on Google's normal Search index, which Googlebot controls, not Google-Extended. The only way to keep your content out of them is to block Googlebot or use snippet controls, and blocking Googlebot removes you from Search altogether, which almost no one actually wants. So if your real goal was to disappear from the AI answers you see in Search, Google-Extended is not the lever you are looking for. ![Google Search Central documentation on AI features and your website](https://theplusaddons.com/wp-content/uploads/2026/07/YNLghXUjXaN2_7l1zckLkSdZLAMPZNhX2KRRpWSl7pABOVueBaSV16jZoLvLuNmRM6QAALdKeI6mEhsbkQ9Zlw-scaled.png)Google's guidance on AI features in Search: those are governed by Googlebot, not Google-Extended. Source: Google. ## How to set Google-Extended in robots.txt To opt out of Gemini training and grounding across your whole site, add this to your robots.txt file: `User-agent: Google-Extended Disallow: /` To opt out of only part of your site, disallow specific paths instead of everything: `User-agent: Google-Extended Disallow: /members/ Disallow: /premium/` To allow it, which is the default if you say nothing, you simply do not add a Disallow rule for it. Because Google-Extended is a standalone token, these rules only affect AI training and grounding. They do not change how Googlebot crawls your site for Search. If editing robots.txt by hand makes you nervous, our guide to a [robots.txt generator for WordPress](https://theplusaddons.com/blog/robots-txt-generator-wordpress/) shows a safer way to manage these rules. ![Google blog update on web publisher controls introducing Google-Extended](https://theplusaddons.com/wp-content/uploads/2026/07/qsCIPo_2hnUPy8jyDSHBOLMRy0AbkqV03ZcRnoxWEDQi9u66BljuxmPimE1yHIJZy80gjftHZN3F4aoXvwIzFg-scaled.png)Google introduced Google-Extended as part of its web publisher controls. Source: Google. ## Should you block it or allow it? This is a judgment call, not a universal best practice. Block Google-Extended if you have content-licensing or intellectual-property reasons to keep your material out of Gemini's training set, and you are comfortable knowing it changes nothing about your Search presence or your exposure in AI Overviews. Allow it if your goal is AI visibility. If you want to be a source that AI systems know about and can draw on, opting out of the training and grounding pipeline works against you. Most site owners chasing AI discoverability should leave Google-Extended allowed and spend their energy on being genuinely citable, the same work that helps with [AI search engine optimization on WordPress](https://theplusaddons.com/blog/ai-search-engine-optimization-wordpress/) as a whole. The decision is about your priorities, not about a hidden ranking penalty, because there is not one. ## Manage it without editing robots.txt by hand Google-Extended is only one of dozens of AI tokens you might want to manage, and a stray typo in robots.txt can quietly undo the rule you meant to set. This is where [RankReady](https://store.posimyth.com/plugins/rankready/) helps. It lets you allow or block Google-Extended from a single screen alongside GPTBot, ClaudeBot, PerplexityBot, Bytespider, and more than two dozen other AI crawlers, and it writes the rules to your robots.txt for you. It also supports the newer Content Signals directives, ai-train, search, and ai-input, so you can express intent more precisely than a blunt allow or block, and it logs which AI crawlers are actually hitting your site so your choices are informed by real data rather than guesswork. Unlike some AI systems that ignore robots.txt entirely, Google-Extended is one that genuinely respects it, so managing it well is worth the few minutes. ![RankReady AI crawler control for WordPress including Google-Extended](https://theplusaddons.com/wp-content/uploads/2026/07/ciAkTfXosiz7_4_GHOtxZqkdVcB4xxw4xcECvMZI_8Tmpbb8Nv0YHhcz8P8JzumhNQMAncMSKr4H7vgK1OOZzA-scaled.png)RankReady manages Google-Extended and 30 other AI crawlers from one screen and writes the robots.txt rules for you.
