What is google database?
Here is a google database: 216.239.39.98. The following is a definition of the google database by Daniel Brandt: "I understand that google databases are part of google databases in the United States, Europe, and even India. They are used to guide the balance and possibly"
Databases and updates
Andy Beal describes google updates and their relationships with databases.
"Before google updates its primary index (www.google.com), it first changes in other databases. In this way, a small number of users get the test results of the new results, and then return the available results to each user. This process generally lasts for 2 to 4 days ."
Why should we observe this database?
I asked the experts who often observe the database why they did this. They replied, "they watched the database closely because a year ago, google's database center is still predictable. Google dance will first update the reverse link in www2.google.com and www3.google.com, and then upload the updates to other databases in the next few days, the new reverse link implies that the ranking has been re-estimated throughout the database. It is usually an update every month ."
"Once the same new data appears in www2 and www3, the ranking will become stable. Therefore, if you observe these databases, you will get some new inspiration from these new indexes, so that you will make corresponding optimization plans for your website in the next update ."
Therefore, many people will observe the database and study whether the google algorithm has changed. But in the last few months, google's database became unpredictable.
