Search engines have continually updated their algorithms to better understand and deliver what people are seeking. They have also worked to better identify and separate the high-quality content from the low-quality so they are able to provide users with the information that will best serve their needs.
As search engines have become better at predicting which pages will be the most useful, customers have also begun to realize that they have the right to expect relevant and valuable material. The industry has evolved to the point where if you want to appeal to the modern audiences, you must design content that focuses on these customers rather than the search engines. When your primary intention is to create highly engaging material that people can appreciate and learn from, you will succeed both in attracting your ideal customers and in ranking well with the search engines.
Marketers no longer chase the algorithm, they optimize content for the user.
