you call that content? All I see are a bunch of images plus the specs for each car. What's so specially about it?
High Quality contents are king. then you have to do off page like directory submission, link building , forum posting, blog commenting etc gradually you will get visitors.
You can start writing articles and submitting them in websites that are integrated to Google adsense like bukisa and triond. You will share a certain percentage of the adsense earnings with sites. I am not very experienced with this myself, so take it for what it is worth. Promote anywhere you can. Find forums, facebook groups, e-mails and make your presence known with comments and links to your answers or articles. To make money with Google, one has to work and keep on working. You determine how much you want to earn at the end of the month by putting enough time every day. Good luck
Do SEO to get your blog on page 1 and you will get traffic. Then, if your content is unique and good, visitors will revisit and share it.
