The page still loads normally; it just does not appear in Google Search or AI Overviews.<\/p>\n<h2>How the noindex tag works<\/h2>\n<p>There are two ways to set noindex, and they have the same effect (<a href=\"https:\/\/developers.google.com\/search\/docs\/crawling-indexing\/block-indexing\" target=\"_blank\" rel=\"nofollow noopener\">Google Search Central, Block Search indexing with noindex, accessed November 2026<\/a>):<\/p>\n<pre><code>&lt;meta name=\"robots\" content=\"noindex\"&gt;<\/code><\/pre>\n<pre><code>X-Robots-Tag: noindex<\/code><\/pre>\n<p>The meta tag goes in &lt;head&gt;; change <code>name=\"robots\"<\/code> to <code>name=\"googlebot\"<\/code> to apply the rule to Google only. X-Robots-Tag is a header the server sends, so it also works for PDFs and images. Googlebot has to recrawl the page to see a change, and for less important pages Google says that can take months.<\/p>\n<h2>Nosnippet, max-snippet and AI Overviews<\/h2>\n<p>The AI Search Checker also flags pages that carry nosnippet. From Google&#8217;s robots meta tag documentation (<a href=\"https:\/\/developers.google.com\/search\/docs\/crawling-indexing\/robots-meta-tag\" target=\"_blank\" rel=\"nofollow noopener\">Google Search Central, Robots meta tag specifications, accessed November 2026<\/a>):<\/p>\n<ul>\n<li><code>nosnippet<\/code>: do not show a text snippet or video preview. It also prevents the content from being used as a direct input for AI Overviews and AI Mode.<\/li>\n<li><code>max-snippet:[number]<\/code>: caps the snippet length in characters. <code>max-snippet:0<\/code> equals nosnippet, and <code>max-snippet:-1<\/code> lets Google choose.<\/li>\n<li><code>data-nosnippet<\/code>: an HTML attribute that keeps one section out of snippets while the rest of the page stays usable.<\/li>\n<\/ul>\n<p>Google says a page needs to be indexed and eligible to show with a snippet to appear as a supporting link in <a href=\"\/en\/glossary\/ai-overviews\/\">AI Overviews<\/a> and AI Mode (<a href=\"https:\/\/developers.google.com\/search\/docs\/appearance\/ai-features\" target=\"_blank\" rel=\"nofollow noopener\">Google Search Central, AI features and your website, accessed November 2026<\/a>). Noindex fails the first condition and nosnippet fails the second. To hide one passage, such as wholesale prices, put data-nosnippet on that passage instead of nosnippet on the whole page.<\/p>\n<h2>Blocking in robots.txt hides your noindex from Google<\/h2>\n<p>A common mistake is blocking a page in <a href=\"\/en\/glossary\/robots-txt\/\">robots.txt<\/a> and adding noindex at the same time. Googlebot cannot crawl the page, so it never sees the noindex, and the page can still appear in results if other sites link to it. Google also does not support noindex inside robots.txt. To get a page out of results, allow crawling so Google can read the noindex.<\/p>\n<h2>Where accidental noindex comes from<\/h2>\n<ul>\n<li><strong>WordPress setting:<\/strong> the &#8220;Discourage search engines from indexing this site&#8221; box under Settings, Reading.
