Recently, the "Purple Field server network Interruption" event in the Internet is quite popular attention. Many point stone Forum members to send a post consultation: we stored in the Purple field server site So what will be the impact? Robin gives the following analysis:

The search engine robot will revisit the site that has already been indexed in order to bring the Site page update or revision information back to its indexed database. If a site is not accessible when the search engine robot visits, this time the search engine will not immediately judge that the site is not valid, because each site can not be guaranteed to operate every moment. However, if the site let search engine robot to eat several times, this is not good, because the search engine robot will think that the site has been invalidated, the next search engine index the site's data will be deleted.

What does it mean for a search engine to delete data from your site? Sites that rely on importing traffic from search engines will be hit hard.

So in the "purple Field server network Outage" event, which sites will suffer disaster, and which sites will not be affected?

Robin once made a speech in the May 2007 Xiamen Search engine Strategy conference on the theme "Let the search engine how to efficiently index the site," the concept of a search engine robot crawling cycle. Search engine robot will be based on the information update frequency of the site to form a unique crawling cycle. In general, the site of frequent information updates will be favored by search engine robots. Of course, although your site content is not often updated, if there are frequent updates of the site to you import chain, this will also cause the search engine robot frequent visit to that site will also patronize your site.

Your site if the search engine to patronize the frequency of high, also means that in the Purple field server down the time when the search engine robot visits your site doors times than other sites will be greatly increased, these sites will suffer the biggest negative impact, the search engine is likely to the site's index data to delete.

If your site a few months lazy to update, there is not too much active outside the chain, perhaps in search engine robot return to the server network has returned to normal, stored in the Purple field server This type will be spared in this disaster.

My feeling is that in a certain period of time, should not be removed from the database, the screen is possible. When the spider's normal access, it will slowly recover, but the weight of the domain name may be reduced
