03Classification

Update types

Each confirmed rollout is classified into a category to support analysis. The category does not predict impact on your site, but it points to which layers to review first.

01

Core

Broad ranking system updates. They often affect relevance, quality, and content usefulness signals.

02

Spam

Changes focused on detecting and reducing spam, link manipulation, or policy violations.

03

System

Rollouts on specific products or surfaces: Discover, AI Overviews, AI Mode, or other search systems.

04

AI Search

Updates linked to generative search, visibility in AI answers, or AI Search-related signals.

05

Other

Confirmed changes that do not clearly fit the categories above or have mixed classification.

04Diagnosis

How to interpret a traffic drop

A recent update does not automatically mean a penalty. These questions help prioritize the next step with more clarity.

01

Does the timing match?

Compare rollout start and end dates with organic traffic, impressions, and positions in Search Console.

02

Is the impact broad or concentrated?

Site-wide drops suggest a systemic factor. URL-group drops point to intent, content, internal linking, or cannibalization.

03

What type of update was it?

A spam update calls for a different review than core. System changes require looking at the affected surface, not only blog or hub pages.

04

What should you avoid changing for now?

Avoid major redesigns or content purges during rollout. Observe, segment, and document before irreversible changes.

05Data

Methodology and data refresh

The radar consolidates updates Google has communicated publicly and organizes them for quick reference.

  • Data refreshes automatically every 24 hours with no manual work required.
  • Start and end dates reflect the communicated rollout period, not necessarily impact on your site.
  • When an official link is available, you can review details on Google Search Status Dashboard.
  • For business decisions, combine this context with technical audit, content, and measurement.
06FAQs

Frequently asked questions

How often is this radar updated?+

Data refreshes automatically every 24 hours. You do not need to do anything manual to see newly confirmed updates.

Does this tell me if my site was affected?+

Not directly. It shows confirmed Google rollouts. To measure impact on your site you need Search Console, Analytics, and segmented analysis by URLs, queries, and dates.

What is the difference between a core update and a spam update?+

A core update adjusts broad ranking and quality signals. A spam update targets manipulation and low-quality practices that violate policies. The diagnosis and response are not the same.

Should I change my site every time there is an update?+

Not necessarily. First verify whether dates align with your drop, which URLs or queries moved, and whether the update type applies to your case. Reacting without diagnosis often makes the problem worse.

What should I do if traffic dropped and there was a recent update?+

Document timing, segment affected traffic, review critical pages, and prioritize hypotheses by rollout type. If you need external perspective, a strategic conversation or SEO audit helps order the next step.
