One of my clients is a major language-learning company, and I have ghostwritten bi-monthly blog content for them about English grammar, American culture, travel, food, music, and a variety of other topics.
The data:
50+ blog posts between 1200-2500 words written, edited, and proofread
100+ learner activities for gated content (behind a paywall)
50,000+ monthly visitors to the blog from countries all over the world
This writing also includes content research, keyword research, audience analysis, and SEO-optimization for Google rankings. The writing is geared towards English language learners outside of the United States who are interested in learning about American culture and improving their language skills. I often take very difficult concepts (such as grammatical features of English) and explain them in a simplistic way so that learners of any level can understand the concept.
