If you are writing online your posts should be brief, clear, checked for spelling and grammar and consistent. Your blog may not have broad appeal if it has limitations in these, so your EBooks and public posts can benefit from a professional proof-reader, or extra classes in English, whether it is your first language or not. Whether you write a blog, a book or anything else, your only tool to deliver your message is language, and you should gain all the skills you can with it. If you don’t have time for this, use the services of someone with the best language skills you can find.
Affiliate marketing is commonly confused with referral marketing, as both forms of marketing use third parties to drive sales to the retailer. The two forms of marketing are differentiated, however, in how they drive sales, where affiliate marketing relies purely on financial motivations, while referral marketing relies more on trust and personal relationships.
