Depending on the type of work and instructions of the client, we use BuzzSumo to search for topics, and then the writer does his research and uses creativity to write content.
After that SEMrush Writing Assistant helps optimize content and Premium Grammarly to proofread the article. Although content is ready at this stage, our best content writing services include the review of a professional editor.
We also have the premium version of CopyScape to check for plagiarism although it never comes to that due to standard operating procedures of our content marketing department.
