Google released the Helpful Content Update often called HCU to reward websites that truly answer reader questions. The idea behind it is simple. Content should be written for people first, not only for search ranking. Many affiliate sites lost traffic because their articles looked like short product summaries with many links but little real guidance. Sites with deeper reviews, clear explanations, and honest pros and cons often stayed more stable. The update pushed site owners to think about reader value before promotion. How is this change viewed in SEO circles?
