作為一名站長(zhǎng),大家一定關(guān)注自己站點(diǎn)百度的收錄,應(yīng)該都知道百度搜索提供了一段自動(dòng)推送的js代碼,可將任意網(wǎng)頁(yè)推送到搜索引擎,加快收錄.如果直接把代碼放在網(wǎng)站,推送的js代碼會(huì)重復(fù)提交推送,這樣是不是很不好,今天維易PHP培訓(xùn)網(wǎng)分享一篇不重復(fù)推送的教程.

?CMS技巧

工作原理是文章加載時(shí),會(huì)再百度搜索當(dāng)前文章的url地址,如果百度未收錄,查詢結(jié)果中會(huì)匹配到“沒(méi)有找到該URl.您可以直接訪問(wèn)”或"很抱歉,沒(méi)有找到與"文字內(nèi)容.當(dāng)代碼確認(rèn)頁(yè)面已經(jīng)收錄時(shí),將會(huì)把文章的欄目catid和文章id保存成數(shù)組,存儲(chǔ)到緩存,方便下次直接獲取來(lái)判斷是否已經(jīng)推送過(guò)了.

百度自動(dòng)推送服務(wù)對(duì)象及原理

JS鏈接推送代碼以網(wǎng)頁(yè)為最小對(duì)象,服務(wù)于全平臺(tái)多終端,PC站和移動(dòng)站均可使用.
安裝代碼的頁(yè)面在任意平臺(tái)(瀏覽器、微信、微博)被加載時(shí),頁(yè)面鏈接會(huì)被第一時(shí)間推送給百度,從而提高站點(diǎn)新內(nèi)容的發(fā)現(xiàn)速度.CMS技巧
