I know this is obvious for most of you but while Google Ads (AdWords) has a way to exclude your site for coming up in the search results for specific keywords, Google organic search does not. You cannot tell Google, please do not rank my site when people type in keyword X or Y.

John Mueller from Google confirmed this obvious statement on Twitter saying “No – just focus on what you really want to be seen as being relevant for.”

You can use negative keywords in Google Ads but not in organic search.
