Clear filtersGoogle ranking filter
A colloquial label for reduced website visibility. Distinguish manual actions, algorithm changes and technical problems; traffic decline alone does not identify a cause.
Definition and sourcesGoogle Search Console
A Google service reporting on search presence, indexing and selected technical problems. It does not purchase rankings. Reports change over time, and the tool does not guarantee every submitted page will be indexed.
Definition and sourcesGoogle spam update
An update to Google's systems detecting spam-policy violations. A coinciding traffic drop does not prove causation; website and data analysis are needed.
Definition and sourcesGooglebot
The name of Google's search crawling agents. User-Agent headers are easily spoofed; crawler identity can be verified using recommended methods.
Definition and sourcesGrey-hat SEO
An informal label for supposedly borderline SEO practices. It is no official safety category; policy compliance depends on the action, not the label.
