So I encourage all newbies and expert in SEO, SMM, SEM and also business owners to invest more in producing unique and valuable content instead of buying tools to make your lives easier. For me SEO is a broad industry that relates to all industry so it's not easy to compete. However my secret in order to compete and dominate is very simple and you probably doing it already. Focus on producing quality/valuable/unique content, build hard to get links using it and strong on-page optimization. (if it's not working for you I think you're doing something wrong, your effort/budget is not enough or your site sucks or your product sucks or your price is to expensive or your over optimizing on-site and off-site)
This is just my opinion based on my experiences so if disagree with me feel free to comment something below. I'm very open to hear some of your thoughts and willing to answer some of your questions.
