Tack “&udm=14” on to the end of a normal search, and you’ll be booted into the clean 10 blue links interface. While Google might not let you set this as a default, if you have a way to automatically edit the Google search URL, you can create your own defaults.
Truthfully, the way I cut out most of the noise everywhere is to search using duckduckgo lite on Librewolf/Mull browsers. That with ublock origin (and block cookie banners), noscript, and redirection extensions to nojs alternatives like libreddit, scribe, invidious, along with putting various bypass paywall scripts into unlocks filter list. It all just adds up to an overall better experience with fast to the point results.
