I have quite successful game site (found in my signature) with 5,000 visits per day, but I want to bring it to the next level, meaning I want to increase its traffic significantly to 50,000 visits per day.
I tried different method like promoting my site in social networks (Facebook, Twitter, Pinterest, etc.), positing in relevant forums and blogs, writing articles and buying traffic. I even optimized my site for SEO.
All those methods worked by I didn't succeed in increasing the traffic significantly.
Can you please give help to understand what am I missing?
