Very good idea, I fully support you. I don’t know exactly how, but this idea was partially implemented on our website writemyessay if I’m not mistaken, it was done in the Business Manager in the “Audiences” section. Which audiences you need depends on the specifics of your business and your funnel. If you have questions about the funnel in your business, you don’t know what audiences you need to collect in the advertising account, and your head is spinning from exceptions, then I think you can find information on the Internet.
