Articles on Internet Marketing and Social Networking

### I need 20 articles in total 10 articles on Internet marketing and 10 articles on Social networking (facebook, twitter, G+) All the articles must be minimum of 500 words and should be SEO optimized with a keyword density of about 3% It goes without saying that all the articles must be 100% original and I'll check all the articles from copyscape. If found that the articles are plagiarized I'll not pay for it. My budget for the project is limited so please bid accordingly. Happy bidding. Regards,
