Why can I still see my WiseIntro page?
Google is a massive search engine with lots of changing information every day. To work properly, Google relies on technological cookies within a browser.
Even when you delete or un-publish your WiseIntro page, the page is still cached within cookies for the search engine. The page link will show in the search results, but when clicked will not lead to an active page.
It can take a few weeks for this sort of information to be fully flushed out from search results.
