export default function robots(): MetadataRoute.Robots {
return {
rules: {

You can customise how individual search engine bots crawl your site by passing an array of user agents to the rules property. For example:
app/robots.ts
import type { MetadataRoute } from 'next'
export default function robots(): MetadataRoute.Robots {
return {
rules: [
{
userAgent: 'Googlebot',
allow: ['/'],
disallow: '/private/',
},
{
userAgent: ['Applebot', 'Bingbot'],
disallow: ['/'],
},
],
sitemap: 'https://acme.com/sitemap.xml',
}
}Output:
User-Agent: Googlebot
Allow: /
Disallow: /private/
User-Agent: Applebot
Disallow: /
User-Agent: Bingbot
Disallow: /
Sitemap: https://acme.com/sitemap.xmlRobots object
