If you're running a top quality business and would only want similar quality from the Internet marketing services you use, Radiux directory might interest you.

Radiux claims to focus on maximum search engine visibility and higher search engine ranks for every US business.

This improved yellow page service from Radiux directory is said to surpass traditional business directories and even search engine directories (often because of spamming).

Do you know why?

"Unlike other directories entries in the Radiux directory can not be confirmed using an email account - which anybody can set up for free in just a Minute - but companies have to enter a valid phone number which is confirmed by an automated system. No junk can find its way into the Radiux directory and the system even tracks if the number is still in service."- Source

That phone number checking/validation may seem like a great barrier for now. But scammers/spammers are getting more and more tricky to track these days. Let's wait if they'll still be able to think of something to game this type of service.

Am I just being too pessimistic or what?
