面包屑導(dǎo)航的原理與作用

面包屑(Bread Crumbs)即把用戶從根路徑開始一級(jí)級(jí)帶到當(dāng)前頁面的導(dǎo)航處理，它有助于用戶更輕松的在網(wǎng)站中定位，也是界面的一個(gè)組成部分。面包屑導(dǎo)航的原理是根據(jù)不同的頁面來分頁導(dǎo)航，從而一步步把用戶從根頁面引導(dǎo)至當(dāng)前頁面，維護(hù)著你當(dāng)前的層級(jí)關(guān)系，面包屑導(dǎo)航的起源于古代的標(biāo)記路徑的方法，用來返回當(dāng)前位置的最初出發(fā)地，即從哪里出發(fā)。面包屑導(dǎo)航有助于用戶快速定位當(dāng)前頁面位置，并有助于減少訪問亂套的層次，而對于搜索引擎優(yōu)化及網(wǎng)站內(nèi)鏈接構(gòu)建也是有益處，它們是一種互動(dòng)性比較強(qiáng)的網(wǎng)站導(dǎo)航服務(wù)，能夠幫助用戶快速了解到頁面在整個(gè)網(wǎng)站當(dāng)中的位置，幫助用戶回到上一步去更改信息、選擇，從而提升用戶的體驗(yàn).

一句話次導(dǎo)航是什么？為什么要做一句話次導(dǎo)航？

一句話次導(dǎo)航是什么次導(dǎo)航：在網(wǎng)站的頁腳，用首頁的目標(biāo)關(guān)鍵詞打上錨文本指向給首頁。目的是增加目標(biāo)關(guān)鍵詞的內(nèi)鏈，提高URL的權(quán)重。一句話次導(dǎo)航：編輯一句完整話語，在里面出現(xiàn)多個(gè)關(guān)鍵詞，給每個(gè)關(guān)鍵詞添上首頁鏈接，這個(gè)就是一句話次導(dǎo)航。為什么要做一句話次導(dǎo)航每個(gè)網(wǎng)站首頁可以做3-5個(gè)目標(biāo)關(guān)鍵詞，欄目頁面可以做1-3個(gè)關(guān)鍵詞。但往往首頁上的幾個(gè)關(guān)鍵詞，還有欄目上的關(guān)鍵詞無法都放到主導(dǎo)航上，甚至可能主導(dǎo)航上的
