month love Shanghai irregular update makes people confused, while ranking up between is another station at a loss. Last week the love of Shanghai is showing a "page updated normally, page snapshot of backsliding." However, from the results of view, web page snapshot is contrary to the traditional "snapshot backwards is right to be reduced the sign of the law. From the fact analysis, now the search engine rules may be: a snapshot of the correction by retrogression or bring greater opportunities, are as follows: comprehensive analysis of binary

analysis to find the reasons, after the corresponding solution, a solution that has been provided in the above discussion. But besides more is the integration of internal and external website optimization, such as:

A: website internal optimization, mainly for the integration of structure, home cleaning useless code, such as: too many similar effects flash pictures, because the page is too big for.


: a home can not update the snapshot

C: home page update frequency for small, this is mainly due to the design defects caused. In the daily update site only to update the inside pages, and page changes.

For example, each time through the chain spider crawl to the site index, but always failed to access or slow, next time will come again? Even if the index page in the article, will not blame all over the home above stability.
