想說分享的資訊那麼多，順便賺賺過水廣告，所以弄了一個轉址站（news.flog.cc），但又不太確定這樣跳離率這麼高、網站停留時間又低的網站，放在子網域會不會也連帶影響到主網域，從 Matt 給的建議應該是否定的，子網域和主網域 SEO 權重應分開計算，有影響但不大。
My personal preference on subdomains vs. subdirectories is that I usually prefer the convenience of subdirectories for most of my content. A subdomain can be useful to separate out content that is completely different. Google uses subdomains for distinct products such news.google.com or maps.google.com, for example. If you’re a newer webmaster or SEO, I’d recommend using subdirectories until you start to feel pretty confident with the architecture of your site. At that point, you’ll be better equipped to make the right decision for your own site.
