Read before being scammed.  http://www.complaintsboard.com/complaints/yext-california-c332643.html

I filled out my business information online as well and it indicated that it was a free listing service.  Once the information was completed and you go to the next screen, it asks you to pick a plan to have your listing published online.  The price ranged anywhere from $4 week to $20 week.  What a rip off!   I exited out of the website and the next thing I know, I'm getting a call from an unknown number out of New York asking me why I didn't sign up.

I filled out my business information online through Merchant Circle.  Since then, I have received emails & phone calls from YEXT, letting me know they can provide a great search engine, and list my info on over 50 sites.
