Q：網(wǎng)站加入過(guò)多的Nofollow 標(biāo)簽，會(huì)不會(huì)有影響？

加入過(guò)多的Nofollow標(biāo)簽可能會(huì)對(duì)網(wǎng)站的SEO影響。Nofollow標(biāo)簽是一種HTML標(biāo)簽，用于告訴搜索引擎不要追蹤或傳遞鏈接的權(quán)重。當(dāng)網(wǎng)站過(guò)多地使用Nofollow標(biāo)簽時(shí)，可能導(dǎo)致以下問(wèn)題： 1. 爬蟲(chóng)無(wú)法發(fā)現(xiàn)和索引頁(yè)面：搜索引擎通過(guò)爬蟲(chóng)來(lái)發(fā)現(xiàn)和索引網(wǎng)頁(yè)，但如果過(guò)多的頁(yè)面使用了Nofollow標(biāo)簽，搜索引擎可能無(wú)法追蹤這些頁(yè)面，導(dǎo)致這些頁(yè)面無(wú)法被索引到。 2. 鏈接權(quán)重流失：Nofoll
