Our new ranking algorithm is pretty new, so it is still hand-tuned. As we collect more data, we will improve how well it works on many different types of sites. However, our new architecture also uses anonymized tracking and A/B testing, which will let us run experiments on our search algorithm over time so we can make consistent, ongoing improvements.
