Well it really depends on your marketing strategy, what do you want them to do in your blog?. As to traffic, the best thing you can do is blog commenting and using forums in order to drive traffic back to your site. Just be careful of the rules governing these sites.
Let me help you with blog commenting:
Go to either Google or
DuckDuckGo and run a search related to a post you want to advertise (DuckDuckGo is awesome cuz you can select your targeted country by literally the two clicks and there is no advertising hence is easier to get the best results). Make a great comment giving either your opinion or something to contribute to the post, after that leave your link there with a call to action for them to click on that link and go read your post.
This works really great for any niche. It doesn't really matter what the topic is, as long as you show your expertise and raise awareness as well as interest with your comment.
Try this, you will be surprised by how easy it is and how much traffic you'll get
