Prohibit search engines before going live

Question

I want to prohibit search engines to index my web site before going live with it.
If I simple do a robots.txt with:

User-agent: *
Disallow: /

Would that cause any issues later when I decide to release it for public exposure? (I would of course edit it to allow access before doing so)

Answer 1

No, no problem.

As soon as you change it to allow access, well behaved robots such as googlebot will crawl your site again.

(Bad bots will of course ignore at all times.)
