Daily habit to find the key "Nanjing Guarantee Company" in the www.g.cn rankings, since the customer to provide Google ranking service since the company's website of the keyword has been appearing in the www.g.cn homepage, related search results also show that the customer related company introduction. Position has never wavered, also got the customer affirmation, oneself also very self-confident.
Strange thing happened, today May 21, 2009 morning, the same in Google search related results,
Although the position of the relevant rankings has not changed,
However, you can clearly see from the above picture, "the site snapshots" disappeared, only "similar pages", the most puzzling is that the search results on the customer's website description into a sentence: "Customer first service first." Good faith norms Efficient and fast ", this is where the text ah.
Think of a search engine will typically use meta description to do the description of the site, or use the catalog Dmoz category to describe the site, or use alt text description, but what I use this site as a description of the content?
After a period of analysis, finally let the search results described into the previous company related introduction.
Here is a brief explanation of the procedure.
1, open the Web site, analysis of the site source files, query where the above description of the text. Check found that the site source code did not find, too strange?
Continue to observe the site
In the website head in Flash, I see familiar text, give me the first feeling, Google will be the website header Flash text made index, changed to do the site search results description.
Next is the analysis of what causes, through the Google Administrator, access to the website console, found that Google spiders just came yesterday, and I saw the site yesterday morning is still good, that is this time the site changes.
When you see the console-the tool-analyze the ROBOTS.TX,
Finally saw the reason, originally is because of robots.txt reason, quickly open a look
It shows
User: *
Disallow:/
At this time finally understand last night in the Web site www.580pm.cn set robots.txt time, the wrong robots.txt uploaded to the customer's website, and then made a timely change,
Over the next few days, the search results have finally become the past:
It's finally back to normal.
Summary: From this event, you can see a few questions clearly
1, Google spiders have been modified in the ranking algorithm, can crawl flash files, and can be similar to people can index the text inside;
2, the description of Google spiders are very hard-working, basically every day to visit the website;
3, the website changes, must be careful;
4, finally through the Google Administrator to analyze the site all the problems encountered, and can be resolved.
