Banners – after testing them out I decided to take down my banner ads since they looked salesy and weren’t working like my affiliate links did. They’re easy to throw up, but distracting and probably won’t get great results. If you try them, be sure to show specific sidebar banners based on the type of content people are reading on your blog (for posts that fall under my SEO category I would show a banner related to SEO, and for posts under my website speed category I would show a different banner). You can do this using a plugin like Widget Logic.
Affiliate marketing currently lacks industry standards for training and certification. There are some training courses and seminars that result in certifications; however, the acceptance of such certifications is mostly due to the reputation of the individual or company issuing the certification. Affiliate marketing is not commonly taught in universities, and only a few college instructors work with Internet marketers to introduce the subject to students majoring in marketing.
