I have registered a new domain with a hosting company. They offer the feature that for each new domain there is an associated placeholder page. Actually it is a "Site not configured page" with some technical text and links to the hosting site.
- submit its URL to search engines right now
- remove the page and submit the URL when the site will be online (could be a couple of months)
- replace the default page with "coming soon" contents and submit the URL
- opt for simplicity and add a blank html page having a focused and well descriptive title and maybe some meta tag
I prefer 4 over 3 because at the moment there aren't precise project details to provide.
What's the proper way to notify search engines that soon this site will be online, without getting penalized for side effects I'm not considering or aware of?
