How to prevent toxic backlinks from site preview deployments?

We use Netlify’s site preview deployments when reviewing proposed changes in a pull request. These site preview deployments stay round and create toxic backlinks to our production site, hurting its SEO. How do we avoid such backlinking?

hi there leecalcote. i am not a super expert on deploy previews, but to my knowledge deploy previews do contain “noindex. nofollow” tags to prevent them from being indexed by search engines.

Can you share a little bit more about where you are seeing/how you know your SEO is being affected? that would help us understand if there is a bug or similar.

also a site name (or API ID, is safe to share) could be helpful. thanks!
