The cause
Marketing, just like any other discipline, has its gameplay rules. Sometimes, a simplified set of rules fits, but more often you have to bind sales, product, design, or even HR and finance departments together to craft an astonishing marketing plan that will work for your case.
Low marketing performance might be caused by weak brand identity, poor Go-to-Market strategy, or ineffectively working digital marketing channels like the website, ads, or SEO. However, before diving in, you must be sure that the basic things are in place.
