Getting more subscribers could be the next one

After I see some improvements of my own blog which my Alexa rank and Google index got higher, as well as the backlinks, the next step that I'm going to implement is to increase more subscribers in my blog. This is another problem on attracting more customers and visitors to my own website because my subscription widget does not attract them. So I need to find unique subscription links for my own blog while I'm performing some search optimisation. I heard that getting more subscribers are one key to be successful in your affiliate marketing revenue, sales and leads. Maybe I should plan out for this and I think it's going to be worth while I'm performing SEO on my own blog.
