Access comes first. We check robots.txt, status codes, canonical tags, rendering and sitemap health so Googlebot and Bingbot can fetch and index every page that matters, work shared with Google SEO and Bing SEO.
For ChatGPT search, OpenAI advises allowing OAI-SearchBot in robots.txt. That crawler is separate from GPTBot, which means a site can appear in search while keeping its content out of model training; changes take about a day to take effect.
Snippet controls such as nosnippet and max-snippet limit what Google shows, including in AI features, and Google-Extended covers use by Google's other AI systems. Each control is set deliberately, page by page, to match what you want shared.
