When you submit your article to blog networks, that means the articles and backlinks are distibuited to lots of blogs. But Google can realize that those are some manipulated networks and handles them as single ones. So take care not to overflow Google and don’t go too heavy with such submission cause you could get a red flag and you could be interpreted as spam. But there are user submitted blog networks with large variety of content, you can sign up to those and generate a massive ammount of targeted free backlinks whick drives you huge traffic – and you can automate the whole process.
