I am in the process of switching everything over to fastmail, which is a paid email service without ads, because I dislike the current state of the advertising industry so much. Plus, I'm now in a financial relationship where I am the customer, not the product.
I might likely do the same for a search page if such a thing existed and the price was right. Until then I use startpage or duckduckgo to (attempt to) retain some anonymity.
