Testing Google indexing
Google is one of the best search engines. Generally, Google is well versed in indexing. Google has a huge database and information collectors, whenever any visitor or user types any keyword into a search box eventually it shows the search results.
Google changes it search policies every now and then that’s why most of the times some indexed site vanish from its database and it is known bad data push.
Such kind of loss of website gives a bad impact because once you have lost the traffic you need to rewrite the URLs. And to rewrite a URL is a tough job and it is not guaranteed that this time you will be able to make website more search engine friendly.
Always, the redirecting job of the old URLs creates problem and that time “pushing lost data” procedure is the only option that you have. As you rewrite a URL, Google returns along with complete indexing.
