1. The main advantage of submitting article submission is your link is doubled, i.e when you submit your article in article directories other user will read your article, if they like your articles then they publish the same article in their blog post with link back to your site.

2. While submitting article you have an option called author biography there you can add your link.

3. Publish your article in top article directories, then Google will automatically crawl your article, but submit unique article. Don't publish single article to many article directories.
