CDN的原理及對(duì)SEO的影響

CDN，即Content Delivery Network，是內(nèi)容分發(fā)網(wǎng)絡(luò)的縮寫(xiě)。其原理是通過(guò)在全球各地的節(jié)點(diǎn)服務(wù)器上緩存網(wǎng)站靜態(tài)資源，使用戶(hù)可以從最近的節(jié)點(diǎn)服務(wù)器獲取網(wǎng)站內(nèi)容，從而提高網(wǎng)站的訪(fǎng)問(wèn)速度和穩(wěn)定性。對(duì)于SEO來(lái)說(shuō)，CDN主要會(huì)對(duì)網(wǎng)站的速度和穩(wěn)定性造成影響。在搜索引擎算法中，網(wǎng)站的速度和穩(wěn)定性已成為重要的排名因素之一。如果網(wǎng)站速度過(guò)慢或者訪(fǎng)問(wèn)不穩(wěn)定，搜索引擎會(huì)將其排名降低，這將導(dǎo)致網(wǎng)站的流量減少，進(jìn)而影響用戶(hù)點(diǎn)擊量和轉(zhuǎn)化率等關(guān)鍵指標(biāo)。因此，通過(guò)使用CDN來(lái)提高網(wǎng)站速度和穩(wěn)定性，有助于提高網(wǎng)站的SEO排名。此外，CDN可以降低網(wǎng)站的服務(wù)器負(fù)載，從而提高網(wǎng)站的承載能力和穩(wěn)定性，進(jìn)而減少因網(wǎng)站崩潰或宕機(jī)造成的影響。

如何處理“被黑”？

步驟一避免問(wèn)題擴(kuò)大立即關(guān)停自己的網(wǎng)站以避免感染其他網(wǎng)站（如果您有權(quán)訪(fǎng)問(wèn)自己的服務(wù)器則最好將其配置為返回503狀態(tài)代碼）。與自己的網(wǎng)絡(luò)托管商聯(lián)系了解是否已經(jīng)采取措施解決問(wèn)題。更改所有用戶(hù)和所有賬戶(hù)的密碼（例如，F(xiàn)TP 訪(fǎng)問(wèn)密碼、管理員帳戶(hù)密碼、內(nèi)容管理系統(tǒng)授權(quán)帳戶(hù)密碼）。刪除所有被串改或被惡意增加的頁(yè)面，并通過(guò)搜狗站長(zhǎng)平臺(tái)通過(guò)死鏈提交告知我們刪除搜狗搜索結(jié)果中的被黑數(shù)據(jù)。步驟二評(píng)估損失使用最新的掃描

服務(wù)器日志是什么？如何查看服務(wù)器日志？

服務(wù)器日志是什么服務(wù)器日志(server log)是一個(gè)或多個(gè)由服務(wù)器自動(dòng)創(chuàng)建和維護(hù)的日志文件，其中包含其所執(zhí)行活動(dòng)的列表。簡(jiǎn)單來(lái)說(shuō)，服務(wù)器的日記就是記錄網(wǎng)站被訪(fǎng)問(wèn)的全過(guò)程，什么時(shí)間到什么時(shí)間有哪些人來(lái)過(guò)，什么搜索引擎來(lái)過(guò)，有沒(méi)有收錄你的網(wǎng)頁(yè)，從你的網(wǎng)站工作的第一天你的日記就有了。搜索引擎對(duì)一個(gè)網(wǎng)站存在的影響可謂是方方面面。如果要做好SEO，不論是前臺(tái)的前端開(kāi)發(fā)、頁(yè)面設(shè)計(jì)、產(chǎn)品交互，還是后端的運(yùn)維

阿里云CDN設(shè)置80端口還是443端口

建議使用443端口，因?yàn)?43端口是HTTPS協(xié)議的默認(rèn)端口，可以提供更加安全的數(shù)據(jù)傳輸。同時(shí)，使用443端口也可以避免某些網(wǎng)絡(luò)環(huán)境中80端口被封鎖的問(wèn)題。如果需要同時(shí)支持HTTP和HTTPS協(xié)議，可以將80端口重定向到443端口。
