Two older algorithms that remain in force. Shiliu targets pages dominated by advertising and pop-ups; Tianwang targets sites leaking user data or embedding malicious code.
Shiliu
- Advertising occupying a large share of the content area.
- Pop-ups and floating layers interrupting reading.
Tianwang
- Malicious code and stolen user data.
- Sites compromised and serving harmful content.
Why they still matter
Older algorithms are not retired; they continue running alongside newer ones.
Alien Road
Cómo lo aplicamos
Clients assume older announcements are historical. They are not, and a site can be caught by a rule published a decade ago. We audit against the full set rather than the recent ones.
