Why not submit a sitemap with the appropriate <changefreq> tags -- if you set that to "always" for the homepage, the crawler will know that your homepage is very volatile (and you can have accurate change freq for other URLs too, of course). You can also give a lower priority to your homepage and a higher one to the pages you prefer to see higher in the index.
I do not recommend telling crawlers to avoid indexing your homepage completely, as that would throw away any link juice you might be getting from links to it from other sites -- tweaking change freq and priority seems preferable.

为什么不提交带有适当
我不建议告诉爬虫完全避免对您的主页建立索引，因为这会丢弃您可能从其他站点的链接中获得的任何链接汁 - 调整更改频率和优先级似乎更可取。
