搜索線(xiàn)上公開(kāi)課重要知識(shí)點(diǎn)集錦！

關(guān)于網(wǎng)站開(kāi)發(fā)： ? 前端開(kāi)發(fā)： 1. 了解HTML和CSS基礎(chǔ)：包括掌握HTML基礎(chǔ)語(yǔ)法，理解HTML文檔結(jié)構(gòu)，了解CSS屬性，元素和單位，以及實(shí)現(xiàn)一些有趣的布局效果。 2. 理解JavaScript語(yǔ)言：包括JavaScript變量、數(shù)據(jù)類(lèi)型、代碼流程控制和函數(shù)，以及了解常見(jiàn)DOM API和Ajax異步技術(shù). 3. 了解Bootstrap和jQuery：Bootstrap是一個(gè)重要的前端開(kāi)發(fā)框架，為網(wǎng)站開(kāi)發(fā)提供響應(yīng)式和一致的界面，jQuery是一個(gè)常用的JavaScript庫(kù)，可以快速開(kāi)發(fā)交互效果和動(dòng)畫(huà)效果。 ? 后端開(kāi)發(fā)： 1. 了解HTTP協(xié)議：了解Web服務(wù)器、客戶(hù)端與瀏覽器之間的通信，以及HTTP協(xié)議報(bào)文格式和狀態(tài)碼等。 2. 理解PHP語(yǔ)言：PHP是世界上最流行的服務(wù)器端腳本語(yǔ)言，不僅可以生成動(dòng)態(tài)網(wǎng)頁(yè)，還可以操作數(shù)據(jù)庫(kù)。 3. 掌握MySQL：MySQL是當(dāng)前最流行的關(guān)系型數(shù)據(jù)庫(kù)管理系統(tǒng)，理解MySQL的安裝、數(shù)據(jù)類(lèi)型、查詢(xún)語(yǔ)句，以及常見(jiàn)的優(yōu)化技術(shù)。

網(wǎng)站被做了大量垃圾外鏈&;黑鏈，會(huì)被百度判罰嗎？

一般來(lái)說(shuō)，如果網(wǎng)站被垃圾外鏈和黑鏈攻擊，百度也會(huì)對(duì)其進(jìn)行懲罰。百度通過(guò)爬蟲(chóng)技術(shù)系統(tǒng)會(huì)屏蔽受到攻擊的網(wǎng)站，降低其權(quán)重，甚至降低在搜索結(jié)果中的排名，減少網(wǎng)友的訪問(wèn)量。嚴(yán)重的情況下，網(wǎng)站甚至?xí)凰阉鹘Y(jié)果中完全排除，受到百度永久性懲罰。所以網(wǎng)站管理者應(yīng)該加大力度建立防護(hù)機(jī)制，防止網(wǎng)站被惡意攻擊。

網(wǎng)站為什么要做獨(dú)立IP

同IP網(wǎng)站被攻擊，服務(wù)器下面的其他網(wǎng)站更容易被牽連，造成被黑或者打開(kāi)失敗等問(wèn)題。其次，同IP網(wǎng)站被降權(quán)，會(huì)降低搜索引擎對(duì)這個(gè)IP地址的綜合評(píng)分。比如：同IP下大量網(wǎng)站都被降權(quán)了，你的站即使做的好，排名也極難提升！這就是所謂的近朱者赤近墨者黑，所以一般來(lái)講，好的網(wǎng)站都是用著獨(dú)立IP地址。

網(wǎng)站更換圖片引用地址，導(dǎo)致全站關(guān)鍵詞排名掉光，是什么原因

SPRIT 提問(wèn)于 3年之前親愛(ài)的ZAC老師：之前網(wǎng)站排名很好的（大詞也在首頁(yè)）。網(wǎng)站上星期更換了文章圖片的引用地址，圖片儲(chǔ)存在做另一臺(tái)服務(wù)器，并且使用另一個(gè)完全不相關(guān)的域名來(lái)解析這臺(tái)圖片服務(wù)器，類(lèi)似于圖片做“對(duì)象儲(chǔ)存”。原本圖片是儲(chǔ)存在源碼中的（與網(wǎng)站同一域名）圖片在顯示和抓取上沒(méi)有任何問(wèn)題，但是在更換了圖片調(diào)用地址一個(gè)星期后，網(wǎng)站關(guān)鍵詞排名全部掉個(gè)精光?，F(xiàn)在想知道，這是什么原因，更換文章圖片

請(qǐng)問(wèn)新站如何快速提高權(quán)重和排名？

以下是幾個(gè)快速提高新站權(quán)重和排名的建議： 1. 優(yōu)化關(guān)鍵詞：確保您的網(wǎng)站上的關(guān)鍵詞是與您網(wǎng)站內(nèi)容相關(guān)的，并且這些關(guān)鍵詞被合理地放置在標(biāo)題、正文、圖片等位置上。這有助于搜索引擎更好地索引您的網(wǎng)站內(nèi)容。 2. 內(nèi)容更新：發(fā)布高質(zhì)量、有價(jià)值的內(nèi)容能夠吸引更多的用戶(hù)和搜索引擎對(duì)您的網(wǎng)站進(jìn)行關(guān)注和收錄。頻繁更新內(nèi)容并保持質(zhì)量是提高新站排名和權(quán)重的關(guān)鍵。 3. 建立外部鏈接：與您網(wǎng)站相關(guān)的其他網(wǎng)站的鏈接
