網(wǎng)站為什么流量異常？網(wǎng)站流量異常10大原因（3）

3. 網(wǎng)站被黑客攻擊：黑客可能會(huì)針對(duì)某個(gè)網(wǎng)站進(jìn)行攻擊，導(dǎo)致網(wǎng)站流量異常。黑客可以通過(guò)攻擊手段如DDoS攻擊（分布式拒絕服務(wù)攻擊）或SQL注入等方式，大量發(fā)送請(qǐng)求或篡改網(wǎng)站內(nèi)容，導(dǎo)致網(wǎng)站流量急劇增加。

企業(yè)站想從TAG列表，項(xiàng)目列表優(yōu)化突破

Gavin Jiang 提問(wèn)于 3年之前企業(yè)站現(xiàn)在的工具查的BR4~5的樣子，想從TAG列表，項(xiàng)目列表優(yōu)化突破，有個(gè)不好決定的小問(wèn)題》》在列表加H標(biāo)簽會(huì)不會(huì)影響首頁(yè)跟內(nèi)頁(yè)。薛峰回復(fù)于 3年之前不會(huì)！正常使用H標(biāo)簽就可以了1 個(gè)回答Zac 管理員回答于 3年之前不太明白這個(gè)問(wèn)題背后的邏輯。在列表頁(yè)面加H標(biāo)簽，和其它頁(yè)面（首頁(yè)和其它內(nèi)頁(yè)）有什么關(guān)系？沒(méi)什么關(guān)系吧？所以也不會(huì)影響其它頁(yè)面。不過(guò)

關(guān)鍵詞排名沒(méi)有了

我自己的網(wǎng)站在4月份的時(shí)候，主關(guān)鍵字排名前三位，穩(wěn)定了一段時(shí)間，后來(lái)修改了一下標(biāo)題和關(guān)鍵字，直接掉到100名以后了。8月份的時(shí)候，通過(guò)對(duì)網(wǎng)站的原創(chuàng)內(nèi)容增加，慢慢又恢復(fù)了，主關(guān)鍵字排在前10位，大概過(guò)了三四天，我什么都做。又沒(méi)了，直接掉到200名。直到現(xiàn)在還沒(méi)有恢復(fù)。到現(xiàn)在，我也不知道該怎么做了。我的網(wǎng)站內(nèi)容，90%都是原創(chuàng)內(nèi)容，平均400-600字左右。外鏈很少發(fā)，外鏈不好做了，也不知道該往哪里發(fā)

4、搜索引擎降權(quán)造成被降權(quán)的原因有很多，如短時(shí)間內(nèi)制造大量垃圾鏈接，友情鏈接連帶處分，以及各種黑帽手法等，一般比較嚴(yán)重的降權(quán)會(huì)導(dǎo)致網(wǎng)站的關(guān)鍵詞在搜索引擎結(jié)果頁(yè)中的排名全無(wú)，帶來(lái)的結(jié)果就是網(wǎng)站的流量收到重大的影響，嚴(yán)重時(shí)甚至被K。處理方式：首先分析到底是什么原因?qū)е碌木W(wǎng)站降權(quán)，然后制定對(duì)應(yīng)的整改措施，最后等待搜索引擎重新審核。并且要及時(shí)的跟蹤每天的流量變化情況直至關(guān)鍵詞排名恢復(fù)。5、網(wǎng)站分析工具的調(diào)

站點(diǎn)在日常運(yùn)轉(zhuǎn)的過(guò)程中，可能會(huì)遇到流量出現(xiàn)異常的現(xiàn)象，我們這里所說(shuō)的異常是指流量下降達(dá)到一個(gè)較大的比率，且是如幾天以上持續(xù)性的。作為一個(gè)SEOer，應(yīng)該學(xué)會(huì)如何從各個(gè)維度去分析與查找到流量波動(dòng)的原因，這里不僅限于流量的下降，同時(shí)還應(yīng)該關(guān)注流量上升的情況，這樣我們才能發(fā)現(xiàn)流量下降的漏點(diǎn)進(jìn)行亡羊補(bǔ)牢，而對(duì)流量上升的驅(qū)點(diǎn)進(jìn)行順?biāo)浦?，從而保證流量的平穩(wěn)或上升。并不是每一次分析都能找出造成流量變化異常的真
