如何通過(guò)谷歌SEO然后利用affiliate盈利？

網(wǎng)站更新要不要固定時(shí)間段？

張雄提問(wèn)于 3年之前老師好，網(wǎng)站更新要不要固定時(shí)間段，比如每天的某一個(gè)時(shí)間段更新網(wǎng)站，會(huì)不會(huì)提升網(wǎng)站的排名？3 個(gè)回答Zac 管理員回答于 3年之前并沒(méi)有聽(tīng)說(shuō)過(guò)這種說(shuō)法，做網(wǎng)站的過(guò)程中也沒(méi)有看到這種現(xiàn)象。關(guān)鍵是保持更新，具體幾點(diǎn)更新，和排名沒(méi)什么關(guān)系。就算你在固定時(shí)間更新，搜索引擎蜘蛛也不一定在這個(gè)固定時(shí)間來(lái)抓取，等于沒(méi)用。在某些情況下，在特定時(shí)間更新，有利于趕在搜索引擎蜘蛛抓取和算法更新
