Online background checks can't knock on doors

Online sites cannot make or answer phone calls for you, knock on doors on your behalf nor can they obtain court or school transcripts to verify or discount paid-for data. Not all public information is available online and therefore deducts the notion of "nationwide searches." Remember that what you enter is sometimes met with weak or no privacy policy's and now your information is for sale in cyber-space. 

What's important to note
 is real backgrounds don't take "just minutes" to complete. Too much data can be confusing and counterproductive. Know that you may have just bought inconsistent, conflicting and often outdated information.
