Over the past few years, we’ve released a series of blog posts to share the methodology and process behind our search ranking, evaluation and algorithmic changes. Just last month, Ben Gomes, Matt Cutts and I participated in a Churchill Club event where we discussed how search works and where we believe it’s headed in the future.

Beyond our talk and various blog posts, we wanted to give people an even deeper look inside search, so we put together a short video that gives you a sense of the work that goes into the changes and improvements we make to Google almost every day. While an improvement to the algorithm may start with a creative idea, it always goes through a process of rigorous scientific testing. Simply put: if the data from our experiments doesn’t show that we’re helping users, we won’t launch the change.



In the world of search, we’re always striving to deliver the answers you’re looking for. After all, we know you have a choice of a search engine every time you open a browser. As the Internet becomes bigger, richer and more interactive it means that we have to work that much harder to ensure we’re unearthing and displaying the best results for you.
