Safari's "Quick Website Seach" Address Bar Feature Redirects Google to Ask Different My default search engine in Safari is Bing (Amazon Gift cards FTW!).

I usually search Google by starting to type "goo" and hitting tab to to autocomplete, which enters search engine mode.

However, Google searches always come here. I removed apple.stackexchange.com from Manage Websites in Safari Search preferences:

But every time I visit the site it is automatically readded.

I don't mind it being there, but why are Google searches directing here?

I won't recommend removing the site from history, however, you can try removing it from "Manage Website data" under Safari privacy preferences and then use command + option +E or Empty Cache under Develop menu.
