40 Google Search Quality Changes for February
This month we have many improvements to celebrate. With 40 changes reported, that marks a new record for our monthly series on search quality. Most of the updates rolled out earlier this month, and a handful are actually rolling out today and tomorrow. We continue to improve many of our systems, including related searches, sitelinks, autocomplete, UI elements, indexing, synonyms, SafeSearch and more. Each individual change is subtle and important, and over time they add up to a radically improved search engine.
Pay attention here because a few of these seem rather important including:
Interval based history tracking for indexing.
Disabling two old fresh query classifiers.
Data refresh for related searches signal.
Consolidation of signals for spiking topics.
Panda update. This launch refreshes data in the Panda system, making it more accurate and more sensitive to recent changes on the web.
Link evaluation. We often use characteristics of links to help us figure out the topic of a linked page. We have changed the way in which we evaluate links; in particular, we are turning off a method of link analysis that we used for several years. We often rearchitect or turn off parts of our scoring in order to keep our system maintainable, clean and understandable.
