On the regularity floating phenomenon of keyword ranking

Note that "floating" rather than "change", the change is random, floating is regular, two words meaning different.

Generally speaking, a website keyword in Baidu's ranking will often or infrequently change, the top keyword ranking will change more, especially those who are SEO strong attention to the vocabulary, stable by the top ranking is every webmaster pursuit of the goal, is also the basis of the site traffic rise. Some webmasters often relate to the ranking of their keywords, including long tail keywords.

Keyword ranking changes in the direction of nothing but the rise or fall (of course, there is no change, not the scope of the discussion, the reason for the rise is: the weight of the site (page) increase, other sites (web) weight reduction, other sites or related pages by K, search engine algorithm changes, etc. the reasons for the decline: http:// www.aliyun.com/zixun/aggregation/8463.html "> website weight by Baidu down, Web page content changes affect algorithm, the weight of other sites rise, the new Web page interference and other factors."

The combination of different factors, leading to their own site keyword rankings will rise or fall. But from my actual tracking situation, found a kind of abnormal regularity changes, is the keyword ranking of the cycle up and down.

I tracked more than 80 long tail keywords, the cumulative 1.5 months, accumulated a large number of daily ranking data. found that some of the keywords (about 15%) These days ranked first second, a few days to shoot 11, 12, and after a few days is the first second. or similar to 1-3-1-3, 2-5-2-5 and other regular changes. During the period of their own web page did not make any changes, other people's Web pages are also old content.　The reason for this change, then, is basically to rule out the aforementioned factors. So what are the factors that lead to such a change in rankings?

The first possibility: Baidu periodic transformation ranking algorithm (fine-tuning)

The second possibility: Baidu periodic change data server (different server data included in different) but not transform algorithm

If this is the first case, why does Baidu want to do this? To interfere with the so-called SEO work, the little trick to keep your mystique secret? It's not impossible to keep his own competitive position, but it doesn't feel like it.

If it is the second case, it is more realistic. A large number of data must be in different servers, the server needs to be maintained regularly, a server to maintain its contained data is affected, the performance result is the end of the ranking results changed. However, does server maintenance need to be so frequent? I see the number pattern: Cycle 2 weeks, ranked 1th, 2, top 5 of the proportion of the figure. From this figure can see the cyclical, probably in half thoughtful week (from the actual data can be more explained), difficulty Baidu every week to take turns downtime maintenance server? It seems that the problem needs to have the computer room management experience to answer.

No matter how Baidu is processing data, for webmasters, it is recommended to do some tracking of their own keywords, rather than an occasional query even if it happened. A period of decline and rise in the rankings are not necessarily reflect the weight of the site changes, master a little rule, from the results of the tick off the "beat" factor, see the real trend of change, to see Baidu's own site evaluation is in the better or worse. Of course, if you can achieve a certain proportion of "stable high ranking", so better. I have 25% long tail keyword is always the first, may be in Baidu all database to give the highest weight bar.
