【网站百科】百度抓取频次多少才算正常？
百度抓取频次多少才算正常？有过一定SEO优化经验的的站长都知道百度站长平台中有一个【抓取频次】的选项，那么抓取频次是干什么用的？是不是抓取频次越高网站就越受百度青睐？什么样的抓取频次才是正常的？下面，爱用建站小编就针对这几个问题为大家分析一下。
什么是百度抓取频次
抓取频次可以通过百度站长工具进行查询，抓取频次是搜索引擎在单位时间内（天级）对网站服务器抓取的总次数，如果搜索引擎对站点的抓取频次过高，很有可能造成服务器不稳定，百度蜘蛛（Baiduspider）会根据网站内容更新频率和服务器压力等因素自动调整抓取频次。
百度抓取频次多少才算正常
很多站长认为百度抓取频次越高对网站越好，其实这是种错误的理解。百度抓取频次多少与网站类型和质量有很大关系，比如你在运营着一个流量站，其盈利方式来源于网站流量，那么这样的网站就需要有大量的内容，百度抓取频次就会很高。但如果你运营着一个企业站，每天并不会产生大量的内容，那么这样的网站百度抓取频次就会低一些。
通过上图可以发现，这个网站近期Z高的抓取频次达到了200多次，这属于正常现象吗？答案肯定是否定的。通过观察，网站前期的抓取频率还比较稳定，每天都在20-30次左右，但在6月4日突然上升到了200多次，6月5日又回到了平时的状态，那么也就是说，只有前期比较稳定的抓取频次才属于正常。
网站抓取频次过高的原因分析
1、百度在抓取频次Z高的那天做了更新；
2、百度抓取了大量的无效页面，可以用robots屏蔽下；
3、网站结构不合理，导致蜘蛛抓取循环，爬取不畅；
如果只是偶尔出现了抓取频次过高的现象大家不需要担心，这有可能是网站更新了大量的内容，观察一段时间，一般过几天就会恢复正常（正常的概念是与平时抓取的频次差不多）。如果经常忽高忽低，可以通过网站日志看一下百度蜘蛛是不是爬取了很多无效的链接，如果有，请先用robots.txt屏蔽，再去百度站长平台更新一下robots文件。
网站抓取频次过低的原因分析
1、长期不更新网站，内容更新不规律，质量残差不齐；
2、新站点，新站点一般会进入百度沙盒期，这期间网站抓取频次将会很低，持续优化即可；
3、设置了抓取上线，如果设置了请改为自动抓取；
4、没有做好链接提交，新产生的链接记得及时提交给百度；
在保证网站内容质量的前提下，请尽量不要自己设置抓取频次。百度会根据服务器压力、网站内容质量等自动调节抓取频次，这样做对SEO会比较友好。
