日本圆周率奇书爆红现象解析 - 从SEO角度看小众出版物的网络传播
最近日本一本关于圆周率的奇特书籍《圆周率1,000,000位数表》意外走红网络，这本最初出版于1996年的小众出版物突然登上亚马逊销售排行榜，库存全部售罄。这个现象为我们提供了SEO和内容传播的绝佳案例研究。
The recent viral success of Japan's peculiar book "Pi to 1,000,000 Decimal Places" provides fascinating insights into content virality and SEO dynamics. Originally published in 1996, this niche publication suddenly topped Amazon's bestseller lists, selling out all available copies.
这本由暗黑通信团出版的书籍售价314日元(约合2.5美元)，全书仅包含圆周率小数点后100万位数字。作者牧野贵树(当时的大学生)通过自编程序计算这些数字，最初仅作为兴趣出版。
Priced at 314 yen (about $2.50), this book published by "Dark Communication Group" contains nothing but the first million digits of pi. Created by then-college student Takaki Makino using his own calculation program, it was initially published as a personal project.
