correct herbergier, in a country flooded with tesla cars, would there be room for BYD?..not that I compare this puny web site with BYD, far from it. But there could be hardly any objection with providing additional advertising at no cost, would it?
Are you not charging for advertising near the top of the list on your website?
The problem is getting your website near the top of Google searches. Especially with no named location in the URL.
I just did a Google search of "eat and drink in Buriram". No sign of HappyVisit anywhere.
Change the URL to include Buriram. If or when you expand to other provinces you can include key words in headings within your website.
Also, consider a new suffix. .info, whilst cheap, is not good.
