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。

反向的鏈接（inboundlinks）

指的是從一個(gè)網(wǎng)頁(yè)到你網(wǎng)頁(yè)的超級(jí)鏈接，從你站點(diǎn)外鏈到網(wǎng)頁(yè)的向內(nèi)鏈接，在查找引擎做鏈接剖析，并依據(jù)相關(guān)性來(lái)對(duì)查找成果排序的時(shí)分有很高的價(jià)值。

要害詞密度（Keyword Density）是指在文章、網(wǎng)頁(yè)、博客等文本內(nèi)容中，某個(gè)關(guān)鍵詞出現(xiàn)的頻率與總字?jǐn)?shù)的比例。通常，要害詞密度應(yīng)該控制在2%-5%之間，這樣能夠有助于提升文章的排名和搜索引擎優(yōu)化效果。但是過(guò)度強(qiáng)調(diào)要害詞密度可能會(huì)導(dǎo)致文章讀起來(lái)不自然、脫離實(shí)際，因此寫作時(shí)要遵循正常的語(yǔ)言表達(dá)方式，不要過(guò)分堆砌要害詞。
