关于全站301后百度2个月权重不转移的问题

威海seo问答威海seo问答
1142

saoniao 提问于 3年之前11.1号全站做了301到新域名，现在12.27近2个月时间，新域名也放出了10分之一的收录。5年老域名，主关键词排名均在首页，301到新域名后，现在主关键词排名都在第三页了，是否是做301影响的呢？谷歌针对301速度蛮快的，目前谷歌排名已经转移到新域名这个新域名之前有我自己备案，长期不使用，备案被下了，新的备案要网站能打开的情况下才可以备案，我就随便找个博客页面

关键词排名消失问题

威海seo问答威海seo问答

吴三佳提问于 4年之前目前在面对google做basalt的关键词，但是有个关键词是有上首页了，但是它的排名断断续续，并不是那种慢慢的掉，也不是说掉个几名之类的，而是一段时间消失了一段时间又上来首页了，这是google的bug吗？反馈在折线图里就是断断续续，没有形成一个连续的线。我原本以为排名应该至少是一条曲折的折线，但在我这边的基本都是断断续续的。2 个回答Zac 管理员回答于 4年之前
