You could use 6 different browsers on 6 different devices, using 6 different VPNs to get IP addresses in 6 different countries on 6 different continents, and completely compartmentalize yourself so that you don't look up any particular thing on 2 or more of those browsers - and Google will still know what you're looking up, and will tailor search results and ads based on your history (potentially including ads for one of the VPNs you used, while you're using another VPN)
