SEO Question-Why do I see different Google results than my customers?

Having worked in this industry for so long, I often forget some basic things. Well, I didn’t forget, but I assumed that other people in this industry have the same level of knowledge as me.

So, when I met a “newbie” asking “Why are my Google results different from my customers” question, I had to take a step back and realize that we are not all equal.

Therefore, in this article, I will answer this seemingly simple question. Although it may be simple for us “informers”, it is not always the case for others.

As a new SEO, one of the scariest things you can do is talk to customers. That’s because you always worry that they will ask you a question you can’t figure out. When you are a newcomer, you can pretend to answer questions through some questions, but some questions will embarrass you.

Of course, even the most environmentally friendly SEO usually knows more than their customers, so you don’t have to fake answers often. I certainly do not advocate forgery. When I don’t know, I find that the best thing you can say is that you don’t know, let me know, and I will call you back. Holmium

few days ago it is like that. A newcomer said to me—a customer saw a different Google result from mine, and I didn’t know what to tell them. Holmium

so let me give you the answer I gave him.

Google, like other engines, is actually composed of thousands of servers. Each server is part of a larger computer cluster. Each cluster forms part of the data center. Each data center is an independent branch of Google.

These data centers are located throughout the United States. In the longest period of time, Google only had about 13 data centers to provide all the results to the world. Now this number is estimated to be around 80.

Although some of these data centers are used for pre-testing results (for example, to test new algorithms before they are transferred to the main data center), most data centers are only used to handle the daily load that Google receives.

These data centers are located in specific geographic areas throughout the United States. They do this to serve the query to the data center closest to the user.

For example, although there are a large number of data centers on the East Coast, people searching from San Francisco are likely to get search results from nearby data centers (such as data centers in Oregon or California).

It is precisely because of the differences in these data centers that people searching in New York will see different results from those in Los Angeles.

We have reason to believe that the behavior of each data center is to some extent independent of other data centers. This means that their update schedule and crawl schedule are different. We can even assume that the algorithm changes that affect the index also occur at different times.

This explains why the search results are different. Because Google constantly updates the index, the results you see near you may be similar to results from other data centers, but ultimately different.

This may be due to how crawlers retrieve sites-crawlers can find sites closer to it more easily and therefore add them to the index faster than crawlers that are geographically farther from finding the same site.

For example, a site in Vancouver, Canada may appear in the California data center a few days earlier than the eastern data center. Because this website will be added to the Western Digital Center soon, it will have an impact on search results that are returned faster.

Think of it as the ripples you see in the water when you throw a stone into a pond. If you drop only one stone, you will see ripples flowing from where you fell. However, if you put two stones close to each other, the time is slightly different, and you will see how the ripples interact when they meet.

The change in the index reflects this interaction. A site can have a subtle but significant impact on the index. However, not all data centers notice these effects at the same time. We can also see that the change in the index increases over time, so the impact of a Vancouver website will increase over time, but the impact of different data centers is different, because changes in other websites will also produce Influence.

As you can see, this is why you see different results in the data center. This is not necessarily because of one thing. Just like search engine optimization itself, it is the culmination of a small event that leads to a noticeable difference.
