When you pay to print an ad in a newspaper or magazine, it doesn't live past its usefulness. Once the newspaper or magazine is read, it can be discarded or left forgotten. Digital marketing, on the other hand, can last much longer. Search engine results, content posted on your website or social media, all those digital formats stay up and accessible. So long as the content you are marketing is relevant, fresh and informative to the reader, it'll last much longer than anything physically printed. And cost less too.
