The chain of
search engine spiders will be included in the "trojan website crawling process, which will cause a significant increase, the website of the page at this time, key words ranking will be promoted; when the site optimization that will remove Trojan, Trojan, Trojan removal, the original search engine included virus page will fail, when the search engine update again, it will cause decrease of the web site included at the moment, key words will fall.
two. The chain fell
included "drop, will cause a decline in the key words.
website optimization process, we are not a revision, the revision is often caused by the loss of data, if 404 pages do not appropriate, will produce a large number of links, it will cause the search engine to the original have included page to make a short time retained, new page will not be immediately released, due to a search engine unable to determine the cause of the cause of the failure on the web server itself is still the website at this time, the search engines crawl after, will release a small amount of pages, which resulted in the reduction of collection.

Trojan, and will not immediately cause the key words down, instead, will cause the rapid promotion of key words, in a short period of time for the following reasons:
server failureAccording to the
2, the chain decreased by
