Đánh giá của SEOBOOK
The ROI on effective SEO campaigns is simply unbelievable, and Google is going to do everything in their power to diminish the ROI of algorithmically focused optimization efforts. As the cost of memory drops and the algorithms improve, the next couple years might separate the men from the boys in the SEO space. Those improvements will drive many SEO practitioners into parallel fields like niche publishing and public relations. 5 years ago was the perfect time to start building your empire. But starting today is far better than starting tomorrow.
