Here are some ideas to consider:<p>1. When I see a domain name with the keywords you are targeting, I associate it with spam. My advice is to come up with a memorable name that is less than 10 letters. Think along the lines of Kayak, Hipmunk, Expedia, and Orbitz for inspiration.<p>2. Figure out why your site is different, and make it your focus. Why should I use this site over Kayak? For example, in addition to Kayak, I will check StudentUniverse, a travel aggregator that focuses on students because they offer discounted rates for my age group.<p>3. Pick a niche to start with. For example, one niche is Americans who want to travel to China. Many Americans do not know about Elong, Qunar, or Ctrip. If you make it easy to discover these sites, this will provide value for your users.<p>4. Once you figure out why you are different and you have a picked a target demographic, start driving traffic to your site by contacting people through email, forum posts, and partnerships.<p>Let's stick with the example above about Americans going to China. I would first email Americans living in China that are writing blogs, and ask them to let you do a guest post about your site. Write about how it is hard to book hotels in China when you are new to the country, and why your site could be helpful for their readers. Second, I would respond to posts where people have questions about booking hotels in China (Thorn Tree Travel forum, R/China, R/travel, Quora, Twitter). Do not spam or you will get deleted. Provide valuable information as a subject matter expert. Third, set up strategic parternships. For example, trade links with websites related to travel in China but in different industries, such as businesses focused on day tours like visiting the Great Wall.<p>5. I think there is a lot of good literature out there for Google Search Adwords, so I will focus on Google Display Ads. Use the feature that allows you to add a list of sites to display your ads on. Make a list of 250 websites you want target that are relevant to your niche, and only displays ads there. Then track which sites are sending you people that are converting.<p>I hope that helps for now. Feel free to email me to discuss further.
