First off, thank you so much for this insightful blog post, it's exactly what I needed. But, my software vendor's affiliate program has a funnel of their own, requiring the prospect to sign up with their email address. Is it appropriate for me to collect the prospects email in the Opt-in page, and then expect the prospect to submit their email a second time in order to signup for the product free seven day trial? If appropriate, do you have any advice for how that should be structured?

It’s important to know where your traffic is coming from and the demographics of your audience. This will allow you to customize your messaging so that you can provide the best affiliate product recommendations. You shouldn’t just focus on the vertical you’re in, but on the traffic sources and audience that’s visiting your site. Traffic sources may include organic, paid, social media, referral, display, email, or direct traffic. You can view traffic source data in Google Analytics to view things such as time on page, bounce rate, geo location, age, gender, time of day, devices (mobile vs. desktop), and more so that you can focus your effort on the highest converting traffic. This analytics data is crucial to making informed decisions, increasing your conversion rates, and making more affiliate sales. 

Given that I am still in reading and preparation phase, I am mainly interested to overlap my niche with real life interests so I could have motivation to produce content on regular basis. Two that I am highly interested are PC parts and Fitness. I am aware they are too general subjects with lot of sites doing the same, but my idea is to produce constant review on PC parts, Laptops, Mobile devices, Accessories all in different categories, create lists like top5 or 10 under XX budget etc. Similar approach I would use if I I decide to go with Fitness path and divide content training advice, review of fat loss methods, supplementation, nutrition etc. I am aware that this will be a long journey and that it can pass few months before sales start to kick in and that’s the risk I am ready to take. My questions are:

Affiliate marketing overlaps with other Internet marketing methods to some degree, because affiliates often use regular advertising methods. Those methods include organic search engine optimization (SEO), paid search engine marketing (PPC – Pay Per Click), e-mail marketing, content marketing, and (in some sense) display advertising. On the other hand, affiliates sometimes use less orthodox techniques, such as publishing reviews of products or services offered by a partner.[citation needed]
