Baidu has been complained of limited capability of crawling and indexing new websites after site revamp. Issues usually include that, old pages’ URL can still be found on Baidu’s SERP, new pages’ URL are not indexed, etc. It’s easy to blame Baidu, but there are certain things as webmaster you could have done on your side before blaming others.
1. Have you removed all the old URL on your pages?
Big websites usually encounter this issue when they are doing site revamp. Huge number of pages, complicated structure, and incomplete QA before launch will give Baidu spider to find the old URL on your new pages.
2. Is the test server in a closed environment and has the test server been shut down after new site launched?
Some testing servers are not been put in local drive or a closed environment, and Baidu spider could find the testing site and index the pages. Therefore by the time the new site is launched, Baidu already have the pages with the same content in their cache, and it wouldn’t index any new site pages. Until you shut down the old server, Baidu will keep those old URL in their cache and display them on SERP instead of your new ones.
3. Have you removed the old IP Address from IIS binding?
Some webmaster haven’t delete the site binding of the old IP address on the web server, hence search engine with access to the IP HOST can access to old content/URL.
However, when it takes too long for Baidu to update the cache or when website use CDN, in which dynamic IP address results in IP synchronization failure, we would suggest you to use Baidu Webmaster Tools – diagnostic tool to test whether Baidu crawl your site correctly. If IP address is incorrect, you can click CrawlDiagnostics_ details in the “error” notify Baidu update IP address to your site.
4.Has the old URL been redirected 301 to the new URL?
Make sure it’s really 301 redirecting the old URL to the new URL? Some webmasters use technologies like Java Script make it like redirect, but it’s not.
5. Have you informed your link building sites to update the link destination?
