Where a site serves separate desktop and mobile URLs, Baidu needs the pairing declared through its mobile adaptation tool.
The options
- Responsive design — one URL, no adaptation needed, and the recommended default.
- Separate mobile URLs with declared pairing rules.
- Dynamic serving, which requires correct signalling and is the most fragile.
Where it goes wrong
Incomplete pairing leaves mobile users landing on desktop pages, and Baidu treating the two as unrelated duplicates.
Alien Road
How we apply this
We recommend responsive design and only maintain adaptation rules on legacy sites that cannot change. Separate mobile URLs double the maintenance and they drift apart within a year on every project we have inherited.
