為了SEO我們常常需要對wordpress做一定優化,今天先給大家分享一個,去掉category的方法,降低目錄的深度。
一是在Wordpress後台固定鏈接里設置;二是通過修改Wordpress核心函數實現;三是通過酷文博Wordpress插件實現。具體插件下載,請查看原文,一鍵下載(下面有鏈接)!
方法一(不推薦使用):
進入 WordPress 後台 -> 設置 -> 固定鏈接:
如上圖所示,就是在將「分類目錄前綴」項設置為「.」,這種方法也可以去除 category,雖然設置簡單,但是效果不理想,容易出現錯誤。
方法二(推薦):
這裡子凡推薦一個比較完善的插件(WP No Category Base)來去除 category。
WP No Category Base 插件功能簡單,就是僅僅為了去除 /category/ 目錄標誌,直接安裝,不需要任何設置就可以使用。

方法三(代碼版,需要折騰代碼):
其實第三種方法適合於喜歡折騰的朋友,特別是不喜歡用插件的朋友,這裡的代碼其實就是 WP No Category Base 插件,直接將一下插件代碼複製到當前主題 Functions.php 中即可:
