I'd like to act as devil's advocate for a bit.

Showing ads according to a search term is totally possible, but having no attribution attached to a "click" or to an "impression" give very little advantage for the marketer who is paying for the ads. There are cost models allowing to pay for the actual action (like installing an advertised application) not just for clicks or views. Re-targeting people who had expressed their interest in a product is a useful tool for marketers as well. Having some kind of link back to the advertising campaign, which your users came from along with their LTV allow you to measure campaign productivity, which helps optimize future campaigns. And much more.

I really like the idea of not being tracked on the Internet, but it's seems like currently it's not feasible to remove a tool many marketers get used to.

People, who downvoted my comment - care to explain? Does downvote button on HN compare to "I don't like what you're saying"?
