4 Differences between good marketing and poor marketing

1. Frequency of changes : Good marketers are continuously scanning the environment for opportunities, customers, profitability, partners etc. They change more, experiment more and probably even fail more during this experimentation but they quickly learn. The most important point is that, among these failures, they find a few successes also which enables them to grow. On the other hand poor marketers do not have good market scanning mechanisms - hence they do not come to know of changes in time - till they are all too visible. Poor marketers change less,  experiment less, fail less but they do not have any successes on which they can build their future.  
2. Source and style of  innovation and adaptation : Good marketers learn proactively from the customers and the behavior of their competitors and from marker intelligence . Poor marketers innovate and adapt reactively by copying competitors or merely through internal discussions.
3. Management : Good marketers manage their people, priorities and focus well. Poor dont.
4. Basis of competition : Good marketers compete based on value and value-for-money. Poor marketers compete based on low prices and low margins.
