The site is only 2-3 months old and it is very young to rank on Google. This is also your first SEO for the site so no past record. SEO works differently. People don\'t expect any result from very first SEO campaigns. The results seen after 3rd 4th SEO. You have to understand that SEO is a regular practice to get success in ranking. It\'s not an one time solution.
There is no content or article on the home page. There are only download links. Google can\'t find your site this way. You should add a home page article with seo optimized. This can get your site noticed by Google. Only backlinks are not responsible for ranking.
thanks a ton
