要害詞安置（keywordplacement）

也被稱為術(shù)語安置，一種關(guān)于詞語在網(wǎng)頁上方位的價值衡量規(guī)范，全部的詞語在網(wǎng)頁上不是對等，在網(wǎng)頁標(biāo)題或許在階段標(biāo)題上的詞語比在正文階段中的詞語更重要。

要害詞安置是指在網(wǎng)站內(nèi)容中適當(dāng)?shù)厥褂藐P(guān)鍵詞來提高搜索引擎排名的技術(shù)。關(guān)鍵詞應(yīng)放置在頁面標(biāo)題、元標(biāo)記、主要內(nèi)容和鏈接文本等位置上。但是，要避免過度使用關(guān)鍵詞，以免被搜索引擎認(rèn)為是欺騙或垃圾信息。優(yōu)秀的要害詞安置應(yīng)該是自然、流暢的，使網(wǎng)站內(nèi)容更富有相關(guān)性和價值，提高讀者的滿意度。
