P&O Cruises have told agents selling their cruises not to use words such as P&O Cruises in their URL’s and the reason is obvious, P&O Cruises want to sell you their cruises themselves there by saving on paying out commission.
Technically this post would break their new rules on having the P&O Cruises brand names within the URL (what you see in the address bar) but as I no longer sell cheap cruises I guess it does not matter that much?
The likely outcome of all this is P&O Cruises ranking higher than any other website for terms associated with P&O Cruises.
