Having a web site for your business is definitely an important first step in promoting your business, but it doesn’t stop there. You have to promote your website as well in order lead people to your website and ultimately to your business.
I’ve added a page to my website listing a few links to websites that promote tourism in one way or another. Some are tourist associations some are accommodation directories. Some are free and some charge, some offer a free trial with the option for say an enhanced listing for a fee.
I hope that these may be a of use in promote your tourism business.
