Understand Google Dance tools

No matter whether I participate in trade fairs, seminars, or speeches at seminars, someone will ask me this question: "What is Google dance ?" I have also heard several different Google dance theories, but there is only one true saying: Google Dance actually refers to the process in which Google reschedules the ranking of its search results. In the Google Dance period (within three to five days), you can find that Google's search results may fluctuate significantly.

How long does Google update?
Google Dance is usually used to describe the process in which Google search engines update their major index results. Google updates its major index results every 36 days (10 times a year. However, in May of this year, Google updated its search results in advance, and it was a big update.

Google's update process can be easily identified by significant changes in search results, as can be seen through Google's updates to web snapshots on all indexed pages. You can see significant changes every minute. However, Google's update process is not like switching between indexes. You can switch from an index list to another index list instantly. In fact, it takes several days for Google to update the main search results.

Google, like other search engines, wins customers by providing authoritative and reliable search results to its visitors at any time. In this way, Google's update process becomes a serious problem. During the update process, Google cannot shut down the server for maintenance. Even a one-minute disconnection may cause unimaginable losses to Google. So we can see the term Google Dance.

In fact, each search engine regularly updates its database to ensure that the latest search results are provided. They only have different update cycles. However, Google, as the leading search engine, has a huge influence. Therefore, we pay attention to its updates.

In the update process of Google, its index is always changing, so its search results will also change a lot. Page level (PageRank) and returned link updates are also completed in this period.

Is it true that only search results are updated?
In fact, this is not the case. After any update process is complete, the page location of Google search results will change. On the one hand, this is because Google's web spider has been active and constantly discovering new sites; on the other hand, it is because once the web spider detects those ineffective "dead" sites, the sites will be deleted from their index list. In the Google Dance process, Google's Robot will retraverse each recorded site, calculate the number of links in and out, and evaluate the value of these links. Then, the PageRank value of each page is calculated based on the PageRank system, and the locations of each site in the list are rescheduled based on this number.
