Hi Vikas,
Article submissions can be done but they require some strategy. If you are guest blogging you can use a site like myblogguest.com to find relevant niche related blogs that you can offer your articles to. This site is not free but can work in some niches.
You can post to squidoo.com ezines and other article sites but they don't hold the same value they used to. Read more.
Here is an effective method. Look for niche related blogs that are active and network within the niche. Once you can show a good amount of value by studying and innovating content, you will be able to post and earn real links.
Lastly my favorite method is to network**^** but place the articles on your own site. Gain bookmarks, Social media mentions, and the indexed content on your own domain.
Hope this helps.
