Just checking if my idea is totally stupid:
There's a lot of [ Call Me ] widgets one can put on a website; all of them require the visitor to initiate the call and spend his/her funds if it's not free.
But would anyone put a widget on their site that allows the visitor to get a call from site owner? Example: [ Let us call you ] button - when clicked, an input field appears - visitor types in their number, clicks [CALL ME]. The backend VoIP operator then connects the visitor's number and the website owner's number.
Any costs paid by website owner of course.
I just thought this can get far more calls as they are free and more sales as the owner will have plenty of time to talk to the visitor as he/she is not trying to end the conversation.
Yes, I know about the 800 numbers. Still, would you use the widget?
