When a client visits a company's website, he does not yet know if he will buy a product or service. Often he has questions, but it is inconvenient for him to consult the methods suggested by the company, and after a while he may forget what he was looking for and which site he visited. At this moment, the business begins a struggle for its time and attention, one of the tools of which is a callback. The callback or call back helps to increase the number of calls and turn potential customers into buyers. I propose to talk about it in this thread. Tips, tricks, warnings, and more.
