    Google algorithm update history

    A timeline of confirmed Google ranking updates with start dates, end dates and rollout length. Recent updates sync automatically from Google's Search Status Dashboard, and major milestones go back to 2011.

    How it works

    Three steps, no signup.

    1

    Scan the timeline

    Updates are listed newest first, with any update still rolling out marked at the top.

    2

    Filter by type

    Narrow to core, spam, reviews or helpful content updates, or search by name or year.

    3

    Match your traffic

    Line up drops or gains in your analytics with update dates to see what may have affected you.

    FAQ

    Google Algorithm Update History questions.

    Where does the update data come from?

    Recent updates come from Google's own Search Status Dashboard, which lists confirmed ranking updates with start and end times. Older milestones such as Panda and Penguin are dated from Google's announcements and confirmations, linked on each entry.

    What is a core update?

    A broad change to Google's ranking systems, released several times a year. Core updates don't target specific sites. Pages can rise or fall as Google reassesses relevance and quality.

    My traffic dropped during an update. What should I do?

    Wait until the rollout finishes, then compare the pages that lost traffic with the pages that now rank. Improve content quality and usefulness rather than chasing quick fixes.

    How often is this list updated?

    The page refreshes from Google's dashboard every few hours, so a new update usually appears the same day Google confirms it.
