做过搜索引擎优化排名的站长都清楚

做过搜索引擎优化排名的站长都清楚，排名上下浮动是很正常的。比如你给一个客户优化网站，今天排在首页第二天你让客户验收的时候就跑到第二页去了。出现这样情况的时候很多。搜索引擎在不断的变换自身的排名算法。这样也相对增加了搜索引擎优化的难度。
Webmasters who have done search engine optimization rankings are aware that it is normal for rankings to fluctuate up and down. For example, if you optimize a website for a client, it will be on the first page today. The next day, when you ask the client for acceptance, it will run to the second page. There are many times when this situation occurs. Search engines are constantly changing their ranking algorithms. This also relatively increases the difficulty of search engine optimization.
三、首页排名的局限性
3、 Limitations of homepage ranking
搜索引擎首页的位置是很局限的，首页的自然排名就10个位置。我们竞争的就是这10位置。具体来说没有10个位置，比如百度：百度自己的产品要占一到1-2个位置，有时候会到3个位置全是百度的产品。最多也就是7-8 个位置是用优化方式能达到的。所有的人都在竞争这几个位置，比如一个共有11家在做优化，不管你怎么优化都会有一个是成功的，总有一个是不成功的。这是做搜索引擎优化的一个不足之处。
The position of the search engine homepage is very limited, and the natural ranking of the homepage is only 10 positions. We are competing for these 10 positions. Specifically, there are no 10 positions, for example, Baidu: Baidu's own products occupy 1-2 positions, and sometimes all 3 positions are Baidu's products. A maximum of 7-8 positions can be achieved through optimization methods. Everyone is competing for these positions, for example, there are a total of 11 companies doing optimization. No matter how much you optimize, there will always be one successful and one unsuccessful. This is a shortcoming of doing search engine optimization.
