You will need to use the services of a professional SEO company. They will indeed find the best solution to your problem. For example, I had used the services of Marketing-One, when I had just created my website. It is an online shop with books, and it is hard to get new users and customers because almost everyone in the United States is buying books from Amazon other big bookstores. Their SEO strategy helped me get a lot more clicks on my website from Google, and also, the number of books sold has increased.
