In the past few days, Google Search has dropped over half of the indexed URLs from Twitter from the Google Search index. Last I checked, it looks like Twitter went from 471 million tweets indexed by Google to 180 million tweets indexed by Google. On Friday, right shortly after Twitter blocked unregistered users from seeing public tweets, I took a screenshot of a site command in Google Search for Twitter. Let’s not forget that Google Search can still show new tweets from Twitter in Google Search. With these changes, Twitter is now recovering and showing up more often in the Google search results.
