關于不帶www的域名的問題

在做域名解析時，應該設置一個不帶www的域名。這樣，當用戶使用不帶www的域名時，可以正常訪問你的網(wǎng)站。

做SEO時需要正確處理帶www和不帶www域名的關系：

我們講過URL標準化的概念，在搜索引擎看來，帶www和不帶www的URL是不同的兩個URL，當它們指向同一個網(wǎng)站時，會讓搜索引擎不懂應該選擇哪一個URL作為主要的。所以，我們建議部分符合條件的主機采用301重定向進行URL標準化設置。

如果你的主機不支持301重定向，把首頁的所有鏈接采用絕對地址的鏈接形式也可以很好解決這個問題。

帶www和不帶www的域名對搜索引擎是同等的，任意選擇其中一個作為主域名，在內(nèi)部鏈接和友情鏈接時，都使用主域名，這樣不會使PR值分散。

菜鳥指南：

不帶www的域名如何設置？假設你的域名是 seowhy.com

在域名管理后臺，域名解析時，設置兩個A記錄：

www.seowhy.com 指向網(wǎng)站IP

空格.seowhy.com 指向網(wǎng)站IP

生效后，通過www.seowhy.com 和seowhy.com 都可以正常訪問網(wǎng)站首頁。

什么是404頁面？當我們地址欄輸入一個網(wǎng)址，由于服務器找不到這些頁面，頁面上會出現(xiàn)提示文字，這就是404頁面。當頁面不存在時。一定要返回404代碼。有的站長認為既然頁面不存在，將用戶301轉(zhuǎn)向到首頁，這種設置方式對搜索引擎不友好的，會讓搜索引擎認為網(wǎng)站上有大量與首頁相同的頁面?，F(xiàn)在基本的虛擬主機都有提供設置404頁面跳轉(zhuǎn)功能，站長應該充分利用。虛擬主機怎么設置404頁面？操作流程如下：1、在本地電

網(wǎng)站誤封Robots該如何處理

robots文件是搜索生態(tài)中很重要的一個環(huán)節(jié)，同時也是一個很細節(jié)的環(huán)節(jié)。很多站長同學在網(wǎng)站運營過程中，很容易忽視robots文件的存在，進行錯誤覆蓋或者全部封禁robots，造成不必要損失！那么如果誤操作封禁了robots怎么辦？今天我們請到了廈門258網(wǎng)站運營負責人——鄭軍偉，為我們分享網(wǎng)站robots誤封禁后該如何操作？【案例背景】網(wǎng)站開發(fā)2.0版本，技術選擇了在線開發(fā)，為了避免搜索引擎抓取開

網(wǎng)站如何做好 301/302 跳轉(zhuǎn)

1. 理解 HTTP 狀態(tài)碼 301/302： HTTP 狀態(tài)碼是用來告知瀏覽器服務器返回的狀態(tài)信息，它是用來表示網(wǎng)絡交互中出現(xiàn)的狀態(tài)。301 是永久性跳轉(zhuǎn)，指示瀏覽器所請求的頁面已永久性移到新位置。302 是臨時跳轉(zhuǎn)，表示瀏覽器訪問新的頁面時會被重定向到另一個暫時的網(wǎng)址，會在指定的時間后返回原來的網(wǎng)址。 2. 定義 301/302 跳轉(zhuǎn)：要定義 301/302 跳轉(zhuǎn)，首先要明確目的，

詳解301永久重定向?qū)崿F(xiàn)方法

1. 使用 Apache 服務器 Apache服務器最常用的方法是通過使用基于.htaccess的Apache的mod_alias模塊。方法是添加以下內(nèi)容的.htaccess文件到你想要重定向的網(wǎng)頁目錄： ``` Redirect 301 /oldpage.html http://www.yoursite.com/newpage.html ``` 2.使用 Nginx 服務器 N
