No. People pay for services that are being made free that should entice customers to sign up. Here is analogy, you give some items in market free but you expect that once customer enters into market, he will buy other stuff. Or suppose that there are some labor intensive services outside and you trying to make it cheaper, optimized and high quality through online. Initially, to generate traffic suppose it would give one free service that clients must have.
Bria, I was comparing paying ads fee and giving some free services.
