1. 響應式網站，即網站的域名和URL都不變，只是根據瀏覽設備而自動調整頁面的大小和內容，這主要是靠HTML5和CSS代碼實現的。 2. 網站的域名和URL不變，但是根據用戶的設備來進行判斷，給用戶不同的頁面，即URL不變，但是HTML頁面發生了變化。 3. 啟用新的子域名，根據用戶的設備來進行判斷，然后進行跳轉。 第一種方式是最佳的方式，但也是最難的，有很多的挑戰。普遍采用的是第三種方式，這種方式從網站優化上和成本上都不是非常好，但是客觀現實的影響，卻比較普遍。還有就是國內的移動網絡的網速實際還比較慢，所以移動端的網站需要進行精簡，如果用第一種方式對桌面端的網站進行適配是肯定不行的。 簡而言之，第一種方式面臨的問題是非智能機的瀏覽器和臺式機的IE6等瀏覽器對HTML5和CSS的支持是存在問題的。第二種方式，因為百度蜘蛛沒有區分移動和桌面的蜘蛛，這樣在判斷跳轉上可能會出現問題，從而對網站的排名和權重有不利的影響。第三種方式，其實是個無奈之選，但是從技術上絕對不是最佳之選。 移動網站優化技巧 下面的內容主要是針對采用第三種方式的網站來給的建議。 1. response websites, that is, the web site's domain name and URL are the same, only automatically adjust the size and content of the page according to the browsing equipment, which is mainly implemented by HTML5 and CSS code. The domain name and URL of the 2. site are unchanged, but they are judged according to the user's equipment, and the different pages of the user, that is, the URL, are changed, but the HTML page has changed. 3. enable the new subdomain to be identified and then jump based on the user's device. The first way is the best way, but it is also the most difficult, and there are many challenges. Generally, there are third ways, which are not very good in terms of website optimization and cost, but the impact of objective reality is quite common. Also, the network speed in the domestic mobile network is still relatively slow, so the mobile site needs to be streamlined, if the first way to the desktop web site matching is certainly not possible. In short, the first problem is that the browser of non intelligent machines and desktop IE6 and other browsers support HTML5 and CSS. The second way, because Baidu spiders do not distinguish between mobile and desktop spiders, which may have problems in judging the jump, which has a negative impact on the ranking and weight of the web site. The third way is actually a helpless choice, but technically it is definitely not the best choice. Mobile website optimization techniques are mainly targeted at third ways to give advice.
