Digital Marketing is better than traditional marketing, can you plz explain the statement?

Basically, the goal of both marketing is same that is to attract and drive visitors of advertising to buy the product thereby increasing the business profit. Basic, difference between both is that if we go for a traditional marketing it is difficult to measure how many people read you’re advertising and how many took favorable action upon viewing it and this demerit is overcome by online marketing in which you can know how many people viewed your advertisement and how many purchased the product. And also cost-effectiveness is a factor which distinguishes between two.
