Hostinger AI Builder SEO for ChatGPT, Perplexity & AI search

Built your site with Hostinger AI Builder? Here is what Hostinger AI Builder's own documentation says about how AI crawlers see it, and the exact settings for robots.txt, llms.txt, structured data and your sitemap. Sources are listed at the bottom.

How Hostinger AI Builder delivers pages to crawlers

Hostinger's help center says new AI Builder websites created on or after September 21, 2026 use server-side rendering, so search engines get the full page content right away. It doesn't say how older sites are rendered, and Hostinger's product page describes sites as ready for search engines that support JavaScript-rendered content. If your site is older, run RankRoot's audit: it fetches the page without running JavaScript, like most AI crawlers.

Why it matters: many AI crawlers don't run JavaScript. If your text only appears after scripts run, they may see an empty page.

Make your content readable without JavaScript

1. Connect a custom domain. Hostinger says the sitemap and robots.txt are generated for websites with a custom domain after publishing.
2. Check that important pages aren't hidden: the Hide page from search results option in a page's SEO settings adds a noindex tag.
3. Optional: Web2Agent, an experimental Hostinger feature for manual mode and WordPress, gives your site an MCP endpoint that AI tools such as Claude can connect to. Turn it on in the site's general settings.
4. Run the free audit on your live URL to confirm what crawlers get.

robots.txt: let AI search crawlers in

1. Hostinger generates robots.txt automatically for sites on a custom domain. Its help center doesn't describe a way to edit it.
2. Open yourdomain.com/robots.txt and check that OAI-SearchBot, PerplexityBot and Claude-SearchBot aren't disallowed. The AI crawler checker tests each bot against your live site.
3. To keep one page out of search, use the page's Hide page from search results option (a noindex tag) rather than robots.txt.
4. If you need different crawler rules than the generated file, ask Hostinger support. We couldn't find a documented setting for it.

Which bots to allow or block: robots.txt for AI crawlers and the AI crawler list.

Add llms.txt

1. Manual mode: open Website settings > General settings, turn on Enable LLMs.txt under Web2Agent settings, then publish. Hostinger creates the file at yourdomain.com/llms.txt.
2. Agentic mode: Hostinger says it generates and manages llms.txt for your domain every time you publish. There's nothing to turn on.
3. Hostinger says the file includes only links and descriptions from your website, so good page titles and meta descriptions make a better llms.txt.
4. Check the live file with the llms.txt validator. Turning the toggle off removes the file.

Add JSON-LD and head code

1. Manual mode: expand Pages and navigation, open a page's settings and choose SEO settings to set its meta title, description, URL and keywords. The AI SEO Assistant there can draft the title and description for you to review.
2. Agentic mode: there's no settings form. Ask the AI directly, for example "update meta title 'Your brand: what you do'".
3. Custom code (manual mode): More (⋯) > Integrations > Custom code. Hostinger places <meta>, <link> and <style> tags in <head>, and <script>, <noscript> and <iframe> tags at the end of <body>. Add data-render-head to a <script> tag that must load in <head>.
4. Custom code only shows in preview and on the live site, not in the editor. Update the site to publish it.

<script type="application/ld+json" data-render-head>
{
  "@context": "https://schema.org",
  "@type": "Organization",
  "name": "Your brand",
  "url": "https://yourdomain.com/",
  "description": "One sentence on what you do and who it's for."
}
</script>

Sitemap

1. Hostinger AI Builder creates and updates sitemap.xml automatically at yourdomain.com/sitemap.xml. For new server-rendered sites it includes dynamic pages such as product and blog pages.
2. Submit it in Google Search Console under Sitemaps. Include www in the URL only if the WWW prefix is turned on in your site's general settings.

Common mistakes

• Expecting robots.txt and the sitemap on a temporary address. Hostinger generates them for sites with a custom domain.
• Leaving Hide page from search results on for a page you want cited. It adds a noindex tag.
• Pasting JSON-LD in Custom code without data-render-head and expecting it in <head>. Script tags go to the end of <body> by default, so check your page source after you update the site.
• Turning on llms.txt with empty page descriptions. Hostinger builds the file from your links and descriptions.
