网络营销-文摘

• Provide unique perspectives and content on topics
• Think about their visitors, making sure the sites meet their visitors’ needs
• Give visitors reasons to come back, and other sites reasons to link to them (they update content regularly, and most offer in-depth information, such as tutorials, reviews, or in-depth explanations).

无非是提供独有的、高质量的，频繁的内容更新，且辅之以具有相关性的反相链接。
