While the technology is complicated, the explanation is simple: log data enable our engineers to refine algorithms for the benefit of all search users. If clicking on the top results occurs for any given query, it signals that we are doing something right. If people are hitting 'next page' or typing in another query, we learn something is wrong. Every time a user searches on the web, you benefit from what Google has learned from millions of previous searches. However, rather than a solved problem, the search science is still in its infancy. By launching hundreds of innovations in search just during the last year, we're constantly trying to improve search so you'll hopefully find among the first results the website that contains the answer you were looking for in midst of
more than a trillion unique URLs .
We aim to always balance innovative product development with a serious respect for users' privacy. For us, this process starts with providing transparency and allowing users control. Alma explained the ways we're working to provide our users with more transparency and choice: things like the
Ads Preferences Manager ,
Google Dashboard , and
Data Liberation Front . And she referred to the challenges engineers face to achieve transparency and control with respect to different categories of data such as logged-in vs. unauthenticated data.
In the coming months, the Brussels office will be hosting more TechTalks, where other Google engineers will share what they're working on, how they approach solving some exciting challenges, and the opportunities they see coming up. We'll announce the talks on this blog. Keep tuned.
