Your site should be designed so that the average user can easily access accurate information about a travel destination.
Accuracy is of the utmost importance as people will be relying on your information to plan their vacation. It is suggested that you choose a niche, a small area or single travel topic to cover. You will need to cover a lot of information even when covering a small area.
Your main source of income will be generated by banner ads or commercial listing with links to website that are related to tourism in the area you cover. Thus, if you cover the state of New York you can offer your service to New York;s bed and breakfasts, amusement parks, restaurants, hotels, RV parks, car rental agencies, sight seeing tours, tickets show, and other related sites.
