No-code DNS setup
Root vs www
Choose one canonical hostname and avoid crawler requests bypassing Prerender Buddy.
Root vs www
Root and www are different hostnames.
1example.com
2www.example.comPrerender Buddy protects the exact hostname you add. If you add www.example.com, crawler requests to example.com are not automatically protected.
Recommended setup
Use www as the protected hostname when possible.
1www.example.com -> Prerender Buddy
2example.com -> redirect to https://www.example.comThe redirect should preserve the path.
1https://example.com/blog/post
2 -> https://www.example.com/blog/postHow to test
1curl -I https://example.com/blog/post
2curl -I -A "Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)" https://www.example.com/blog/postThe root domain should redirect. The www response should show Prerender Buddy headers such as x-prerender-cache.
When to configure both
Configure both root and www only if you intentionally want both hostnames to serve pages directly. For most sites, one canonical hostname plus a redirect is cleaner for users, crawlers, and Search Console.
Ready to check the setup?
After DNS or middleware is deployed, use Verify Installation from the site dashboard and check the logs tab for crawler requests.
