為什么百度快照直接跳到了網(wǎng)站頁面？而沒快照！

回答：通常產(chǎn)生這種問題的大概率原因是：網(wǎng)站整體更新的非常慢造成的，百度沒有對(duì)頁面進(jìn)行‘快照’的緩存，只保存了基礎(chǔ)的鏈接信息！其次，網(wǎng)站如果加了禁止緩存的代碼，也會(huì)出現(xiàn)這個(gè)問題！可以聯(lián)系A(chǔ)5這里幫忙查看喲！

吳學(xué)涯提問于 3年之前Zac老師，您好?？茨鷮懙臅_始SEO工作的，目前做了4年了，現(xiàn)在在一家500強(qiáng)公司工作。問題：很多網(wǎng)站底部有網(wǎng)站地圖這個(gè)菜單，我知道對(duì)爬蟲是有作用的，但是對(duì)用戶來說有什么作用，是一種內(nèi)容信息架構(gòu)，還是起到什么作用。請(qǐng)指教。PS：很多國(guó)外公司的網(wǎng)站有網(wǎng)站地圖在頁面上，蘋果和惠普都有，但是微軟沒有。中國(guó)大陸大部分網(wǎng)站沒有，也有有的。福州嘉藝網(wǎng)絡(luò) 回復(fù)于 3年之前網(wǎng)站地圖的

使用平臺(tái)抓取斷工具也不能完整顯示，是不是就可以認(rèn)為沒有收錄完整了？

不一定。平臺(tái)抓取工具對(duì)于網(wǎng)站的完整性是存在一定局限的，可能存在一些頁面或內(nèi)容無法被完整抓取的情況。因此，只能通過多種來源的數(shù)據(jù)進(jìn)行比較和分析，以得出更全面的結(jié)果。同時(shí)，對(duì)于重要的網(wǎng)站和數(shù)據(jù)可以采用多種方式進(jìn)行抓取和備份，以避免數(shù)據(jù)丟失。

百度快照不更新，快速有效的小技巧你可能需要用上

面介紹的搜索引擎優(yōu)化。其中最重要的技巧就是通過更新網(wǎng)站內(nèi)容來吸引搜索引擎的抓取。一般來說，百度對(duì)網(wǎng)站的索引是要求有持久度的，也就是說要保持網(wǎng)站的更新，為搜索引擎提供新的內(nèi)容，這樣搜索引擎的快照便可以隨之更新。另外，你也可以試試百度站長(zhǎng)工具來提交你的網(wǎng)站鏈接，也可以觸發(fā)快照的更新。另外還可以通過搜索引擎廣告來進(jìn)行推廣。最后，必須注意網(wǎng)站內(nèi)容一定要原創(chuàng)、有價(jià)值，這樣百度才會(huì)把你的網(wǎng)站作為優(yōu)質(zhì)結(jié)果。

【官方說法】詳談百度快照前世今生

百度快照是百度搜索引擎的一個(gè)重要功能，它可以將網(wǎng)頁在被百度抓取時(shí)的狀態(tài)保存下來，并在搜索結(jié)果頁面中展示。用戶可以通過查看快照來了解網(wǎng)頁內(nèi)容的更新情況和變化。在過去，百度快照經(jīng)常被用于反映網(wǎng)站的收錄和排名情況。但隨著搜索引擎算法的不斷升級(jí)，快照的重要性已經(jīng)逐漸減弱，更多的是作為一種參考資料來被使用。同時(shí)，百度也對(duì)快照做了一些改進(jìn)和優(yōu)化，如提升了快照的更新速度、增加了網(wǎng)頁快照的存儲(chǔ)空間等，以提
