From blog installation, to design, content creation and all methods of marketing – I STILL do it all. (Note: Many other affiliate training packages use MY affiliate sites as examples without my permission. That’s because those so-called ‘trainers’ don’t have affiliate sites. They pretend to be working affiliates to take your money, but they don’t have any real experience.)
Demographic targeting gives you the ability to target specific customers you think are likely to purchase your product or hire your services. Every time someone visits your website and fills in a form, it gives you an idea of who your customers really are and lets you discover important details about them such as age and interests, which better shapes your services to match their needs.
Because users have different operating systems, web browsers and computer hardware (including mobile devices and different screen sizes), online ads may appear to users differently from how the advertiser intended, or the ads may not display properly at all. A 2012 comScore study revealed that, on average, 31% of ads were not "in-view" when rendered, meaning they never had an opportunity to be seen. Rich media ads create even greater compatibility problems, as some developers may use competing (and exclusive) software to render the ads (see e.g. Comparison of HTML 5 and Flash).
Always disclose your affiliate relationship. Most visitors will probably understand that graphic ads will lead to your getting paid, but if you write a review or use an in-text link as a recommendation, you want your readers to know that may lead to compensation as well. This ensures you retain transparency and trust with your readers, but also, it's required by the FTC's endorsement rules.
