phosphor 提問于 3年之前

請(qǐng)問zac老師，ev，dv，ov時(shí)候?qū)ε琶淖饔檬窍嗤牧?？?yīng)該怎么選擇，從安全性上基本上都一樣的，但是排名方面不知道是否有不同了？謝謝！

Zac 管理員回答于 3年之前

就我所知，不同級(jí)別的https證書在SEO效果上沒有區(qū)別，數(shù)據(jù)通訊安全性上貌似也沒有大差別，只是身份驗(yàn)證程序和對(duì)主體資質(zhì)要求上有差別，當(dāng)然，價(jià)格也就有差別。

我只是用的免費(fèi)的，所以沒實(shí)驗(yàn)過。但沒有聽說過不同版本有任何SEO差別的說法。

網(wǎng)站被鏡像會(huì)被百度判罰嗎？

如果網(wǎng)站被惡意鏡像導(dǎo)致內(nèi)容大量重復(fù)，這可能會(huì)被百度算法認(rèn)為是作弊行為，從而受到懲罰。百度會(huì)懲罰重復(fù)內(nèi)容較多的網(wǎng)頁，使其排名下降，甚至可能完全禁止收錄。因此，應(yīng)始終確保自己的網(wǎng)站內(nèi)容獨(dú)特，避免被惡意鏡像。

網(wǎng)站一個(gè)內(nèi)容有多個(gè)不同的收錄，對(duì)網(wǎng)站有沒有影響

題：網(wǎng)站一個(gè)內(nèi)容有多個(gè)不同的收錄，對(duì)網(wǎng)站有沒有影響回答：有一些網(wǎng)站出現(xiàn)了參數(shù)類型的收錄，例如：www.xxx.com/1.html?123 還有一種則是偽靜態(tài)網(wǎng)站靜態(tài)URL和動(dòng)態(tài)URL全部被收錄了！這個(gè)時(shí)候的解決辦法是在Head中增加canonical標(biāo)簽，來確定權(quán)威鏈接，告知搜索引擎！來源：A5營(yíng)銷

主域名任意后綴都能訪問首頁對(duì)SEO有什么危害？

如果主域名任意后綴都能訪問首頁，這意味著同一網(wǎng)站會(huì)有多個(gè)重復(fù)的域名。這會(huì)影響網(wǎng)站的可信度和排名，并降低網(wǎng)站的SEO價(jià)值。搜索引擎可能會(huì)將這些重復(fù)的域名視為網(wǎng)站的重復(fù)內(nèi)容，從而懲罰網(wǎng)站的排名。此外，這也可能導(dǎo)致用戶的混淆，他們可能無法確定哪個(gè)域名是真正的官方網(wǎng)站。因此，建議網(wǎng)站主使用一個(gè)主要的域名來代表其網(wǎng)站，并使用301重定向?qū)⑷魏纹渌蛎囟ㄏ虻街饔蛎?。這樣可以保護(hù)網(wǎng)站的排名和SEO價(jià)值。
