雙向鏈接（tow-waylink）

雙向鏈接（two-way link）是一種在網(wǎng)頁(yè)或多個(gè)文檔之間進(jìn)行相互鏈接的技術(shù)，允許用戶(hù)在一個(gè)文檔中點(diǎn)擊鏈接跳轉(zhuǎn)到另一個(gè)文檔，并且在目標(biāo)文檔中能夠方便地返回到原始文檔。雙向鏈接的概念最早出現(xiàn)在超文本系統(tǒng)（Hypertext System）中，超文本系統(tǒng)是一種通過(guò)文本之間的鏈接實(shí)現(xiàn)非線(xiàn)性閱讀的系統(tǒng)。在超文本系統(tǒng)中，可以通過(guò)鏈接跳轉(zhuǎn)到其他文本，在其他文本中又可以通過(guò)鏈接返回到原始文本，從而實(shí)現(xiàn)多

雙向鏈接（tow-waylink）

雙向鏈接是指兩個(gè)網(wǎng)頁(yè)之間互相鏈接的鏈接關(guān)系，即一個(gè)網(wǎng)頁(yè)上的鏈接指向另一個(gè)網(wǎng)頁(yè)，另一個(gè)網(wǎng)頁(yè)也同時(shí)鏈接回原網(wǎng)頁(yè)。從搜索引擎優(yōu)化的角度來(lái)看，雙向鏈接是一種有效的鏈接策略，它可以在兩個(gè)網(wǎng)站之間建立聯(lián)系，提高兩個(gè)網(wǎng)站的互聯(lián)度，促進(jìn)彼此的流量增長(zhǎng)。但是，雙向鏈接也容易被搜索引擎認(rèn)為是“過(guò)度優(yōu)化”，所以在使用時(shí)需要注意策略和技巧。

也被稱(chēng)作互相鏈接，是對(duì)一個(gè)網(wǎng)頁(yè)有超文本鏈接，一起政策網(wǎng)在鏈接回來(lái)正本的網(wǎng)頁(yè)。
