    Looks like there were a bunch of updates, none really affected my sites negatively, but I think the ones that are important are the following, let me know what you think I left out or if any other those don't really matter:

    Improvements to ranking for local search results. [launch codename ?Venice?] This improvement improves the triggering of Local Universal results by relying more on the ranking of our main search results as a signal.

    More coverage for related searches. [launch codename ?Fuzhou?] This launch brings in a new data source to help generate the ?Searches related to? section, increasing coverage significantly so the feature will appear for more queries. This section contains search queries that can help you refine what you?re searching for.

    More locally relevant predictions in YouTube. [project codename ?Suggest?] We?ve improved the ranking for predictions in YouTube to provide more locally relevant queries. For example, for the query [lady gaga in ] performed on the US version of YouTube, we might predict [lady gaga in times square], but for the same search performed on the Indian version of YouTube, we might predict [lady gaga in India].

    Spam update. In the process of investigating some potential spam, we found and fixed some weaknesses in our spam protections.

    Improved local results. We launched a new system to find results from a user?s city more reliably. Now we?re better able to detect when both queries and documents are local to the user.

    Panda update. This launch refreshes data in the Panda system, making it more accurate and more sensitive to recent changes on the web.

    Consolidation of signals for spiking topics. [launch codename ?news deserving score?, project codename ?Freshness?] We use a number of signals to detect when a new topic is spiking in popularity. This change consolidates some of the signals so we can rely on signals we can compute in realtime, rather than signals that need to be processed offline. This eliminates redundancy in our systems and helps to ensure we can continue to detect spiking topics as quickly as possible.

    More accurate detection of official pages. [launch codename ?WRE?] We?ve made an adjustment to how we detect official pages to make more accurate identifications. The result is that many pages that were previously misidentified as official will no longer be.

    Site:? query update [launch codename ?Semicolon?, project codename ?Dice?] This change improves the ranking for queries using the ?site:? operator by increasing the diversity of results.

    Data refresh for related searches signal. [launch codename ?Chicago?, project codename ?Related Search?] One of the many signals we look at to generate the ?Searches related to? section is the queries users type in succession. If users very often search for [apple] right after [banana], that?s a sign the two might be related. This update refreshes the model we use to generate these refinements, leading to more relevant queries to try.


    International launch of shopping rich snippets. [project codename ?rich snippets?] Shopping rich snippets help you more quickly identify which sites are likely to have the most relevant product for your needs, highlighting product prices, availability, ratings and review counts. This month we expanded shopping rich snippets globally (they were previously only available in the US, Japan and Germany).

    Improved snippets for video channels. Some search results are links to channels with many different videos, whether on mtv.com, Hulu or YouTube. We?ve had a feature for a while now that displays snippets for these results including direct links to the videos in the channel, and this improvement increases quality and expands coverage of these rich ?decorated? snippets. We?ve also made some improvements to our backends used to generate the snippets.
