I've been plugging away with article marketing promoting affiliate products for about 1.5 years now. I've only made a trickle of dollars in that time. I'm not expecting quick riches. I would like to hear from anyone who has had experience with article marketing and is making a steady income with it? Is it strictly a numbers game tied in with quality content, good keywords and finding the hungry niche? How many articles should I be shooting for to post each month to improve my chances of generating steady traffic and an income?
