Dragon shape in the usual Webmaster tools to query Web site SEO data found that the site's snapshots not only did not follow the expected update, but from 2013.7.29 back to the 2013.7.19, which is not a good site optimization phenomenon. So the dragon-shaped hurriedly view the site's other data, found no big changes, then why did the site's snapshots appear back to the file? In most of the webmaster's impression, the site snapshot back not only links not good exchange, but also to a certain extent on behalf of the site has a tendency to drop the right. So the dragon-shaped hurriedly analysis of the reasons for the file, the site is all in accordance with the process of optimization, in the short term no major changes, the dragon shaped into a meditation ...

is anxious to analyze the reasons, to explore the strategy, Dragon shape in the afternoon Webmaster tools to query, found a wonderful phenomenon, that is the morning back to file the site snapshot in the afternoon again back to normal, directly into the 2013.7.31, people simply can not believe. Figure:

What caused the snapshot of the site to change so much in one day? Dragon shape after the site of serious analysis, in the confirmation of the site has not recently revised or changed, friendship Links Normal, the content of the site continued to update, the chain of orderly increase, summed up their views:

I. Web site space impact

Webmaster are aware that if the server instability caused the site often not open, not only will affect the customer experience caused the site jumped out of the rate, but also to a certain extent, causing spiders to crawl the content of the site. Dragon-shaped web site on the server has been in an unstable state, if the search engine crawled out of the spider just came to my site to catch the server can not open, at this time the spider can not crawl from my site to any content, this is the spider will give up on my site access. and Baidu needs to give each site a snapshot, representing the update of the site, in the spider did not crawl to my site content, will be from the previous database to choose one as my day snapshot. Of course, spiders crawling to the site is not only once a day, if in the next crawl found my site can enter, then will give a new snapshot, resulting in the site in the morning and afternoon two different snapshot results. Of course, it can also be seen that Baidu's response is so fast, which before is not conceivable.

Ii. Impact of website content update

We know that the launch of Baidu Spark program, strengthen the site content detection, especially the original and false original identification. Dragon shape in the detection of their own web site recently updated content, found that they made a mistake, that is, in 29th, 30th two days due to operational errors, continuously updated 2 of the same article, resulting in an article has not been Baidu included. From the dragon-shaped speculation, is not in the Baidu Spark program, found a website two similar articles, think one of them is cheating, thus reducing the trust of the site, the article not only not to be included also lead to a snapshot of not update, resulting in a snapshot of the site back to the file. Because the Dragon shape every day update articles, Baidu in the crawl new article gave a new snapshot, so that the original back to the snapshot gave coverage.

Third, Baidu's own algorithm changes

Webmaster recently found a number of unusual phenomena, such as keyword ranking fluctuations, site snapshots often appear to stop or back, the site's collection and external chain instability. These may be related to Baidu's recent continuous algorithm reform, from the beginning of the new Year, has introduced the Green Luo algorithm, pomegranate algorithm, spark original plan, which has a lot of corresponding rules and announcements. Baidu a series of algorithms to adjust and improve, it will inevitably cause some of the site some abnormal phenomenon, although in order to increase the user experience and protect the original, purify the Internet environment, but the change too fast also inevitably appear algorithm error.

Of course, for a snapshot of the site in the morning back to normal in the afternoon, Dragon shape believe there are other possible. As long as we are good at the day-to-day optimization of observation and take the right analysis methods, always in the first time to find some valuable clues, and tracking Baidu algorithm changes in the traces, so in the follow-up to prevent the optimization.
