黑帽SEO（BlackhatSEO）

抽象的說(shuō)，全部運(yùn)用作弊辦法或可疑辦法的，都可以稱為黑帽SEO，比方說(shuō)廢物鏈接，躲藏網(wǎng)頁(yè)，橋頁(yè)，要害詞堆砌等等。

　　黑帽SEO就是做弊的意思，黑帽查找引擎優(yōu)化辦法不契合干流查找引擎發(fā)行政策規(guī)矩，黑帽SEO獲利首要的特色就是短平快，為了短期內(nèi)的利益而選用的做弊辦法，一起隨時(shí)由于查找引擎算法的改動(dòng)而面對(duì)賞罰。

網(wǎng)頁(yè)快照（Cache）是指瀏覽器或網(wǎng)頁(yè)服務(wù)器在第一次請(qǐng)求某個(gè)網(wǎng)頁(yè)后將該網(wǎng)頁(yè)的副本保存起來(lái)，以備將來(lái)再次訪問(wèn)時(shí)使用。通過(guò)使用快照，可以提高網(wǎng)頁(yè)的加載速度，減輕服務(wù)器的負(fù)載，并提供離線訪問(wèn)功能。當(dāng)瀏覽器請(qǐng)求某個(gè)網(wǎng)頁(yè)時(shí)，瀏覽器會(huì)先檢查本地緩存中是否存在該網(wǎng)頁(yè)的快照。如果存在快照，并且快照尚未過(guò)期，則瀏覽器會(huì)直接從本地緩存中加載該快照，并顯示給用戶，這樣可以極大地縮短加載時(shí)間。如果本地緩存中不存在或已

要害詞密度（keyworddensity）

要害詞密度（KeywordDensity）與要害詞頻率（KeywordFrequency）所論述的實(shí)質(zhì)上是同一個(gè)概念，用來(lái)測(cè)量要害詞在網(wǎng)頁(yè)上呈現(xiàn)的總次數(shù)與其他文字的份額，一般用百分比表明，相關(guān)于頁(yè)面總字?jǐn)?shù)而言，要害詞呈現(xiàn)的頻率越高，要害詞密度也就越大。

黑帽SEO（BlackhatSEO）

黑帽SEO是一種不遵守谷歌設(shè)計(jì)的最初目標(biāo)違反搜索引擎規(guī)則來(lái)優(yōu)化網(wǎng)站的行為。它可以說(shuō)是一種“快速站點(diǎn)搜索排名”的優(yōu)化技術(shù)。常見(jiàn)的黑帽SEO（Blackhat SEO）技術(shù)包括文本重復(fù)、關(guān)鍵詞堆積、影子站點(diǎn)和網(wǎng)絡(luò)攻擊等等。這些技術(shù)極易顯示出在搜索引擎優(yōu)化（SEO）領(lǐng)域被視為不道德的結(jié)果。黑帽SEO常常在優(yōu)化的站點(diǎn)沒(méi)有必要的鏈接，以便獲得搜索引擎的排名提升，但是，這只是臨時(shí)的，它們很快會(huì)被谷歌視為誘

黑帽SEO是什么？黑帽SEO能做嗎

黑帽SEO是什么所有使用作弊或可疑手段的，都可稱為黑帽SEO。如垃圾鏈接，隱藏網(wǎng)頁(yè)，橋頁(yè)，關(guān)鍵詞堆砌等。不同于白帽SEO那種放長(zhǎng)線釣大魚(yú)的策略，黑帽SEO更注重的是短期內(nèi)的利益，在利益的驅(qū)使下通過(guò)作弊手法獲得很大的利益。就是采用搜索引擎禁止的方式優(yōu)化網(wǎng)站，影響搜索引擎對(duì)網(wǎng)站排名的合理和公正性，但隨時(shí)會(huì)因?yàn)樗阉饕嫠惴ǖ母淖兌媾R懲罰。黑帽SEO和白帽SEO的區(qū)別黑帽：注重欺騙搜索引擎，采用的是搜索
