There is one direct penalty check
Open the Manual Actions report in the verified Search Console property. If Google has issued a manual action, the report names the issue and provides affected patterns. That is direct evidence. Save the notice and follow the manual-action process.
If the report shows no issue, you do not have a manual action to remove. A third-party tool cannot override the account's status by calling a visibility decline a penalty.
Check security, indexing, and measurement
Open Security Issues for malware, phishing, or hacked content warnings. Then inspect Page indexing, Crawl stats where relevant, and representative URLs. Confirm the correct canonical, indexability, server response, rendered page, and whether a migration or template release changed them.
Compare Search Console clicks with Analytics organic sessions. If Search Console is stable and Analytics falls, investigate consent, tags, channel rules, and reporting before touching SEO. If indexed pages collapse after a noindex deployment, the cause is not hidden.
Classify the graph that remains
| Observation | Next check |
|---|---|
| Clicks down, impressions stable | Position, title, snippet, result features, and click-through changes |
| One page family loses impressions | Template, intent, overlap, indexability, and current result comparison |
| Sitewide impressions fall | Demand, migration, broad indexing, manual action, and update timeline |
| Only Analytics falls | Measurement and consent implementation |
| Brand demand falls everywhere | Market, seasonality, reputation, and offline business changes |
This classification does not produce instant certainty. It prevents expensive work on explanations already contradicted by the data.
Use the official timeline last
After establishing the loss window and affected groups, compare them with Google's Search Status Dashboard and update history. An overlapping rollout makes a ranking-system change plausible. Require a matching pattern before acting on it.
The result of a good penalty check is not a percentage. It is a short list of explanations, the evidence that distinguishes them, and the next reversible test or repair for the strongest one.
