Does Google Have A Parked Domain Detector?

Does Google have a parked domain detector and should I have content on a parked domain that I buy from GoDaddy? The answer is "yes." 

Google does have a “parked domain detector," says Matt Cutts from Google that avoids trying to show those pages in their search results.

If you buy a domain that you intend to use later on, it is always best to write some type of content on your placeholder page so it can be indexed by Google's Googlebot.

You may want to include:

• A paragraph or two on your company 
• Product you will be offering 
• Services you provide 
• Social links 
• Newsletter or email subscription 
• Add a few links to relevant or informative websites that relate to your business
