目前百度Spider抓取新鏈接的途徑有兩個(gè)，一是主動(dòng)出擊發(fā)現(xiàn)抓取，二就是從搜索資源平臺的鏈接提交工具中獲取數(shù)據(jù)，其中通過主動(dòng)推送功能“收”上來的數(shù)據(jù)最受百度Spider的歡迎。對于站長來說，如果鏈接很長時(shí)間不被收錄，建議嘗試使用主動(dòng)推送功能，尤其是新網(wǎng)站，主動(dòng)推送首頁數(shù)據(jù)，有利于內(nèi)頁數(shù)據(jù)的抓取。

那么同學(xué)們要問了，為什么我提交了數(shù)據(jù)還是遲遲在線上看不到展現(xiàn)呢？那涉及的因素可就多了，在Spider抓取這個(gè)環(huán)節(jié)，影響線上展現(xiàn)的因素有：

1、網(wǎng)站封禁。你別笑，真的有同學(xué)一邊封禁著百度蜘蛛，一邊向百度狂交數(shù)據(jù)，結(jié)果當(dāng)然是無法收錄。

2、質(zhì)量篩選。百度Spider進(jìn)入3.0后，對低質(zhì)內(nèi)容的識別上了一個(gè)新臺階，尤其是時(shí)效性內(nèi)容，從抓取這個(gè)環(huán)節(jié)就開始進(jìn)行質(zhì)量評估篩選，過濾掉大量過度優(yōu)化等頁面，從內(nèi)部定期數(shù)據(jù)評估看，低質(zhì)網(wǎng)頁比之前下降62%。

3、抓取失敗。抓取失敗的原因很多，有時(shí)你在辦公室訪問完全沒有問題，百度spider卻遇到麻煩，站點(diǎn)要隨時(shí)注意在不同時(shí)間地點(diǎn)保證網(wǎng)站的穩(wěn)定性。

4、配額限制。雖然我們正在逐步放開主動(dòng)推送的抓取配額，但如果站點(diǎn)頁面數(shù)量突然爆發(fā)式增長，還是會(huì)影響到優(yōu)質(zhì)鏈接的抓取收錄，所以站點(diǎn)在保證訪問穩(wěn)定外，也要關(guān)注網(wǎng)站安全，防止被黑注入。

360搜索蜘蛛IP段及蜘蛛ip被攔截的問題解決方法

威海Spider 威海360Spider
778

1. 360搜索蜘蛛的IP段可以通過搜索引擎或者防火墻等工具查詢獲得，一般包括以下幾個(gè)IP段： 101.226.68.0/24 101.227.0.0/16 39.156.66.0/24 111.30.132.0/24 2. 如果發(fā)現(xiàn)360搜索蜘蛛的IP被攔截了，可以考慮以下幾個(gè)解決方法： - 在防火墻或者網(wǎng)站安全設(shè)置中將360搜索蜘蛛的IP加入白名單； - 通過robots.txt文件進(jìn)行

導(dǎo)致搜索引擎蜘蛛不能順利爬行的因素

威海Spider 威海Spider
1224

1. 網(wǎng)站結(jié)構(gòu)復(fù)雜和不合理：網(wǎng)站結(jié)構(gòu)過于復(fù)雜或不合理會(huì)阻礙搜索引擎蜘蛛的爬行，導(dǎo)致關(guān)鍵頁面無法被索引。 2. 缺乏關(guān)鍵詞和優(yōu)化：如果網(wǎng)站沒有優(yōu)化，或關(guān)鍵詞使用不當(dāng)或缺乏，搜索引擎無法判斷網(wǎng)站內(nèi)容的重要性，從而無法正確推薦網(wǎng)站給用戶。 3. 網(wǎng)頁載入時(shí)間過長：搜索引擎會(huì)優(yōu)先考慮快速載入的網(wǎng)站。如果網(wǎng)站速度慢，搜索引擎會(huì)認(rèn)為網(wǎng)站不夠優(yōu)秀，會(huì)影響網(wǎng)站的排名。 4. robots.txt 文件限制：

百度Spider渲染UA在移動(dòng)端全流量上線

威海Spider 威海Baiduspider
1019

百度Spider在2017年3月同時(shí)推出渲染UA在移動(dòng)端和PC端進(jìn)行內(nèi)測（《百度Spider新增渲染UA抓取公告》），內(nèi)測期間分析了多個(gè)抓取量異常的case，均非渲染UA造成。本周百度Spider渲染UA在移動(dòng)端全流量上線，PC端還未全部覆蓋。特提醒PC站長，截止目前，對搜索引擎和用戶有價(jià)值的內(nèi)容，還是盡量不要使用JS加載的方式，以免造成不能索引等損失。來源：百度搜索資源平臺

百度搜索Spider3.0升級對站點(diǎn)有什么好處

威海Spider 威海Baiduspider
531

尊敬的用戶，我作為AI語言模型，無法進(jìn)行搜索。不過Spider 3.0是一種網(wǎng)絡(luò)爬蟲，可以自動(dòng)獲取網(wǎng)頁內(nèi)容和數(shù)據(jù)，并可以對站點(diǎn)進(jìn)行優(yōu)化和改進(jìn)。升級至Spider 3.0可能會(huì)帶來以下好處： 1. 提高抓取效率：Spider 3.0采用了全新的異步抓取方式，可以加快爬取目標(biāo)站點(diǎn)的速度。 2. 提升數(shù)據(jù)質(zhì)量：Spider 3.0的抓取規(guī)則更加智能化，能夠過濾掉無用信息，使抓取的數(shù)據(jù)更加精準(zhǔn)。 3
