I am used to looking up the ranking of the key "Nanjing Guarantee Company" in www.g.cn every day. Since providing Google ranking services to this customer, this keyword of the company's website has always appeared on the homepage of www.g.cn, and related searches The results also show relevant company profiles for the customer. The position has never wavered, and it has been affirmed by customers, and I am very confident.
A strange thing happened. Today, on the morning of May 21, 2009, the same search results on Google were found.
Although the relevant ranking positions have not changed,
However, you can clearly see from the picture above that the "website snapshot" is gone, only "similar web pages". The most puzzling thing is that the description of the customer's website in the search results has changed to one sentence: "Customer first service" First. Integrity, standardization, efficiency and speed." Where does this wording come from?
I think that search engines generally use META descriptions to describe the website, or use DMOZ categories to describe the website, or use ALT Chinese text descriptions, but what does my website use as the description content? Could it be that Google Using a new algorithm again!
After a period of analysis, the description in the search results finally changed to the previous company-related introduction.
Let's briefly explain the operation process.
1. Open the website, analyze the source file of the website, and check where the above description text appears. After checking, I found that the source code of the website was not found. How strange?
Keep watching the website
In the flash in the head of the website, I saw familiar text, which gave me my first impression. Google indexed the Chinese text in the flash in the head of the website and turned it into a description of the search results of the website.
The next step is to analyze what caused it. Through the Google administrator, I entered the website console and found that the Google spider just came yesterday, and I saw that the website was still good yesterday morning. This means that there were modifications to the website during this period.
When you see the console-tools-analyze robots.tx,
Finally I saw the reason. It turned out to be because of robots.txt. Quickly open it and take a look.

At this point, I finally realized that when I set the robots.txt for my website www.580pm.cn last night, I uploaded the wrong robots.txt to the customer's website, and then made the modifications in time.
Over the past few days, the search results finally changed to the previous ones:
Finally back to normal
Summary: From this incident, we can clearly see several issues
1. Google Spider has been able to crawl flash files after the ranking algorithm has been modified, and can index the text inside like a human;
2. It shows that Google spiders are very hard-working and basically visit the website every day;
3. Be careful when modifying the website;
4. Finally, you can use the Google administrator to analyze all the problems encountered by the website and solve them.
