Actually Nunya, Jafar’s English is very good, with only a few very minor errors, and far better than most English speakers. It is simply not true that you can “barely read it”, it’s as good as yours. Most Americans, Australians and British I see online have very poor spelling and grammar, and use memorized abbreviations and SMS-speak instead wherever possible. You cannot sound as if you have something to teach people, if it sounds as if you still have to learn basic literacy yourself!
From there, results vary over time. Successful affiliate sites are updated regularly, have a clear focus that excites visitors, provide lots of useful content, and many affiliates find the their highest referrals when they invest in advertising as well. I generally write one 1,000 word article per day (minimum of 5 per week) on new sites and it usually takes at least 6 months before I earn my first cent. Most of my sites don’t start earning the ‘job quitting income’ until a couple years after I start them. You can learn more about how long it takes to succeed in affiliate marketing here.
While any “regular” job requires you to be at work to make money, affiliate marketing offers you the ability to make money while you sleep. By investing an initial amount of time into a campaign, you will see continuous returns on that time as consumers purchase the product over the following days and weeks. You receive money for your work long after you’ve finished it. Even when you’re not in front of your computer, your marketing skills will be earning you a steady flow of income.
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.
Despite its older origins, email lists are still a viable source of affiliate marketing income. Some affiliates have email lists they can use to promote the seller’s products. Others may leverage email newsletters that include hyperlinks to products, earning a commission after the consumer purchases the product. Another method is for the affiliate to cultivate email lists over time. They use their various campaigns to collect emails en masse, then send out emails regarding the products they are promoting.
If the answer to each of these questions is a resounding yes, rather than jumping to conclusions immediately, take time to research whether or not others are out there making a sustainable affiliate income from products and content in this niche. In a sense, competition is a good thing here—it'll help you validate your idea and prove that it's worth of building a business around.
