Yeah, Yext called me as soon as I clicked off the ad to purchase their service.  I opted out of the service after reading their terms and conditions but this was AFTER I filled out the initial info blocks and BEFORE checkout.    It is a company promoting your online business presence.  You pay a fee and they put you on Yahoo, Mapquest, Yellowpages; Whitepages or wherever else is offered. (sepearate fees for each site though).  It may be ligit...I think it is....but I opted out because they automatically charge your credit card in one year to renew your account with them.  I don't like that!
