Read an official update record and classify what it confirms, what it suggests and what remains unknown.
Use Google’s Search Status Dashboard and linked announcements to establish a named update’s dates and type. The index in this app covers the recent four-year window plus selected historical milestones. A ranking update, a service incident and a policy announcement are different events; do not combine them into one undifferentiated list of algorithm changes.
A core update concerns broad changes to ranking systems. A spam update concerns systems addressing policy-violating behavior. Reviews updates historically focused on review-related systems. These labels describe a category, not a complete list of targets or a personalized explanation for your site. Read any specific official guidance before adding more detail.
Changes may unfold over several days or weeks. Compare meaningful periods and allow for the documented rollout and available data. A single daily fluctuation can be noisy. Record other events such as deployments, seasonal changes and tracking modifications so the update date does not become the only explanation considered.
Use the card to identify relevant guidance and decide what evidence to inspect next. A core update may prompt a broad usefulness review; a spam concern may prompt a policy review. The conclusion should follow your site’s actual symptoms and evidence. Do not invent a precise target because an industry discussion confidently assigns one to an unnamed change.
Broad changes: investigate segments and competing explanations.
Review current policies and manipulative practices.
Inspect original evidence and the usefulness of review content.
Helpful-content history and Discover-specific updates need their own context.
Hypothetical example: an analyst sees a decline during a documented core-update rollout. She opens the official card, records the start and completion information and reviews comparable query and page groups after the rollout. The deployment log shows that a new navigation template also went live that week. Inspection reveals that several important pages lost internal links. The team addresses that demonstrated issue and separately reviews content usefulness. The update remains relevant context, but it is not treated as proof that a specific hidden factor caused the decline. The report explains both the official event and the site evidence, allowing leadership to understand why the next action was chosen.
A report labels every ranking incident as a content-quality update and assigns an invented target to each date. Readers may mistake a technical service problem for a change in ranking policy or apply the wrong remediation. A reliable index should retain the official event type, link to the source and explicitly state when no more specific target has been published.
Misconception: a named update tells you exactly why your page moved. Correction: it establishes an event and often broad guidance. Your site still requires diagnosis, and coincident timing does not isolate the cause of an individual change.
The bundled index is reviewed at a stated date and cannot automatically know future updates while offline. Use the linked official history for current developments. Historical cards remain useful context, but their review date should be visible.

Choose one recent card and write three statements: what the official source confirms, what site-level question it raises and what it does not prove. Compare the event window with one relevant internal change log.
Use an authorized page or campaign relevant to this lesson, or work entirely from the illustrative sample below. Record proposed changes as drafts until they are approved and implemented.
A documented core-update window overlaps a site template release and a change in seasonal demand.
Before: Any traffic change during the window is assigned to the update.
After: The update is one contextual event alongside site and demand changes.

A traffic decline overlaps a documented core-update rollout and a major navigation deployment. A manager says the date proves the algorithm punished the site’s writing style. Which use of the update index best supports a sound investigation rather than an unsupported conclusion?
