Why are my Tweets on Google after deleting or protecting them?
All public Tweets posted before you select the account setting “protect my Tweets” will still be indexed in a public search engine, including twitter.com/search. Once you have saved your account settings to protect your Tweets, the Tweets you post thereafter will be protected.
Even if you delete Tweets, Google and other search engines cache search results, which means that occasionally old information is still searchable. Although Twitter changes your settings immediately and deletes Tweets immediately, these changes don’t erase old information in Google’s search index.
Any old links appearing in a Google search will lead to Twitter’s truth-telling error page: “That page doesn’t exist!” The old links still appear because Google and other search engines may not have the current information updated in their search index.
Until Google updates the new information and indexes your current status, links to the profile or updates posted prior to removal/protection remain online.
Send Google a request to remove the information:
Google will eventually index updated Twitter information, but if you’d like it done sooner, follow the steps below.
STEP 1: Copy the URL you’d like removed from the site (for example: twitter.com/#!/[username here]/status/12345678)
