I have a Fly hosted website: https://ridly-rubbish-removal.fly.dev/.
The web domain I have purchased and pointed towards the fly.io site is https://ridlyrubbishremoval.com.au/.
I have a robots.txt file in my code that allows google to crawl my site when I am in production. My issue is that the robots are crawling my fly provided domain (https://ridly-rubbish-removal.fly.dev/) and my custom domain (https://ridlyrubbishremoval.com.au/).
How do I stop the fly.dev address appearing in Google and encourage only my own domain (ridlyrubbishremoval.com.au) to be used?
Do I need to build some custom logic in to the robots.txt or is there a more accepted or standardised way to do this? Thanks in advance!
