sitemap提交后，多久能被百度抓取？

通常情況下，sitemap提交后，百度會(huì)在1-2天內(nèi)進(jìn)行抓取。但具體時(shí)間也受到網(wǎng)站規(guī)模、更新頻率、抓取限制等因素的影響。如果長期未被抓取，可以檢查一下sitemap是否存在問題，并通過百度站長平臺(tái)的工具進(jìn)行排查。

從基礎(chǔ)到精通：認(rèn)識(shí)網(wǎng)站301重定向的那些事

什么是ETag？ETag作用有哪些

ETag是HTTP協(xié)議提供的一種用于判斷資源是否發(fā)生變化的機(jī)制。ETag是一個(gè)字符串，由服務(wù)器生成，在資源被更新時(shí)會(huì)發(fā)生變化?？蛻舳苏?qǐng)求資源時(shí)，服務(wù)器會(huì)將資源的ETag值一起返回，客戶端可以緩存資源，并記錄ETag值。當(dāng)客戶端再次請(qǐng)求該資源時(shí)，會(huì)將上次記錄的ETag值一同發(fā)送給服務(wù)器。如果此時(shí)服務(wù)器返回的ETag值與客戶端記錄的值相同，就說明資源沒有變化，客戶端可以直接使用緩存的資源，減少網(wǎng)絡(luò)請(qǐng)求

我的網(wǎng)站同時(shí)有多種格式。需要都列出來嗎？

請(qǐng)?jiān)?Sitemap 中只列出一種格式的網(wǎng)址。包含多種格式的網(wǎng)址可能會(huì)導(dǎo)致抓取工具無法完整地抓取網(wǎng)站。
