It is best to update your website before Baidu.
The webmaster who has done seo tutorials should have done such a thing, that is, he tried to do the external link and change the link a few days before Baidu updates, in order to catch up with the new team and add the external chain. This is also true for my website revision. On the eve of the upgrade, I removed all the old station programs, changed them to the new station, and updated several original articles, the reason for originality is to allow new articles to be indexed as soon as possible. On the contrary, if other articles are reposted, the website may not be updated by the search engine due to content factors.
Do some external links after the new program is launched
After the launch of the new program, I started to do external links and exchange links like the new station. The purpose was to allow search Spider crawlers to better crawl new programs and update them smoothly, just as when the new station was launched, the search engine can be indexed as soon as possible through external links.
Updated content frequently after revision
The updated content is used to attract search Spider crawlers, so that the website is updated every day by the search engine, and thus the well-known Baidu snapshot is updated every day.
On the second day after the revision, the homepage has been updated from the homepage of the old station to the homepage of the new program, and some external links and several original articles have been updated, after a week, Baidu snapshots are updated every day, every other day. I also verified the purpose of doing this experiment. Many people on the Internet say that the major revision of the website is based on the source program, and the website subject has not changed) the statement that the website will be downgraded or k is not completely correct, and the full revision of the website will not necessarily be k-dropped.
Of course, the reasons for the search engine itself are not ruled out here. For example, the search engine's sensitivity to the comprehensive revision of the website is reduced, or the comprehensive revision of the website is no longer subject to downgrading or k-site processing. Maybe Baidu will have an inspection period for all site revisions like the new site. These factors still need to be observed and put into practice.
