I am working in online advertising industry, and many time people use the word
lead is kind of something that a company should achieve. Lead sometimes means a customers who actually bought products or services of the company, but sometimes it also means a customer can just needs to provide his information like name, address, phone to the company.
For example, say, our company got a website about game. In that website, we got a form to ask customer to provide their personal info like email, phone, address... After signed up, the customer can see some demo of the game, but they can not play the game. They can only play the game if they actually pay for it.
So that customer who only signed up the info without paying for product or service is called "customer lead" or something like that.
So what does "customer/sales/product lead" mean?
