現(xiàn)在全網(wǎng)而言，大約有50%以上的站點(diǎn)都選擇了CDN的服務(wù)，主要有：百度智能云、阿里云、騰訊云，這幾家把持主要市場(chǎng)，那么網(wǎng)站為什么要做CDN呢？做了CDN的好處有哪些呢？你可能不了解。

1、使用CDN，可以隱藏掉網(wǎng)站真實(shí)的IP地址，避免被黑客入侵，或者直接進(jìn)行IP形式的攻擊。

2、使用CDN ，可以抗黑客攻擊，只要流量足夠，網(wǎng)站永遠(yuǎn)不會(huì)打不開。

3、使用CDN，更利于蜘蛛抓取，網(wǎng)站的整體抓取頻率，大約會(huì)提升30%。

4、使用CDN，全國(guó)不同節(jié)點(diǎn)的用戶，訪問網(wǎng)站速度會(huì)更快。

注：不要選擇小型服務(wù)商，如果CDN節(jié)點(diǎn)不穩(wěn)定，對(duì)網(wǎng)站而言是毀滅級(jí)的！

網(wǎng)站為什么會(huì)被降權(quán)？

問題：網(wǎng)站為什么會(huì)被降權(quán)？回答：網(wǎng)站降權(quán)的原因非常多，但是總結(jié)一些最常見的降權(quán)原因：1、使用了快排，本身就是作弊排名（什么3天首頁(yè)、7天首頁(yè)、這種都是）。2、網(wǎng)站每天在采集別的網(wǎng)站中的內(nèi)容，而不是自己產(chǎn)出的內(nèi)容。3、網(wǎng)站存在了非常多的空頁(yè)面問題。4、網(wǎng)站收錄的頁(yè)面有很多垃圾頁(yè)面，比如篩選頁(yè)。5、網(wǎng)站URL不當(dāng)，造成太多的內(nèi)容重復(fù)。6、網(wǎng)站服務(wù)器或者DNS非常不穩(wěn)定，，導(dǎo)致搜索引擎抓取異常！來源：A

自適應(yīng)的移動(dòng)端隱藏鏈接會(huì)被懲罰嗎？

如果隱藏鏈接是用于欺騙用戶或搜索引擎，那么它可能會(huì)被懲罰。搜索引擎算法已經(jīng)針對(duì)這種不良行為進(jìn)行了優(yōu)化，如果發(fā)現(xiàn)隱藏鏈接存在，搜索引擎可能會(huì)將網(wǎng)站降低排名或甚至完全從搜索結(jié)果中刪除。但是，如果移動(dòng)端的隱藏鏈接是為了方便用戶使用和提高用戶體驗(yàn)，則它不太可能被懲罰。如果你堅(jiān)持使用移動(dòng)端隱藏鏈接，建議確保這些鏈接與網(wǎng)站主題一致，并且只包含有相關(guān)性的信息。此外，引導(dǎo)用戶進(jìn)入頁(yè)面或執(zhí)行特定操作的鏈接應(yīng)該
