Hi Egol,
Thanks for this, but when you compare the content on that site, it's less content and inferior as well to all those three. That site does not have the credentials as well. Not even a certified rehab in Thailand. Their site is not that useful as well compared to the other sites. I am with you in making the best site, so it's very strange that Google would rank such a site in the top because it's not following that logic.
So you do not think Google uses Authority/Trust when ranking websites?
Best
John
