One of the keys to be successful with digital marketing is to generate more lead. Digital marketer I've been trying to check on different leads generation strategies. Banner advertisement seems to be one of the strategies that caught my attention. I want to ask that what would you say is the main purpose of a banner ad? I noticed that some online brands are using banner ads. Please make me think maybe banner at this for grand awareness.
