Good morning
Just a quick question. Why does AirBNB not get penalised for duplicate content on its sites.
For example, the following two urls (and probably more for other countries), both rank appropriately in the google (UK and COM),
https://www.airbnb.co.uk/help/getting-started/how-to-travel
https://www.airbnb.com/help/getting-started/how-to-travel
Their are no canonical tags, no Alternative etc
If I look at the following
https://www.airbnb.co.uk/s/London--United-Kingdom
https://www.airbnb.com/s/London--United-Kingdom
They both have alternative to point to the other language versions which I would expect. However they also both point to them selves as canonical. Would this not be duplicate content ?
Thanks for your insights
Shane
