All your strategies seems to be helpful one way or the other. However, we must remember that traffic is more useful if we can make money from it - if you can make a sale, or your visitor will click your ads. For me, the best source of traffic is still from search engines. Social traffic are readers and followers, not buyers. Although they can be, it may take a longer time. But if you're very popular, you can make money from selling ad space on your blog. Otherwise, one must have a very credible product to sell.
