I just started implementing some affiliate offers to my blog. And I agree that you have to find the balance of offering something to your readers without being too pushy or like what you said without selling your soul haha. For me sine my blog is about travel i just mention where I stayed or what hotel and if I liked it and I recommend it I put an affiliate link.
The first widely publicized example of online advertising was conducted via electronic mail. On 3 May 1978, a marketer from DEC (Digital Equipment Corporation), Gary Thuerk, sent an email to most of the ARPANET's American west coast users, advertising an open house for a new model of a DEC computer. Despite the prevailing acceptable use policies, electronic mail marketing rapidly expanded and eventually became known as "spam."
So far we’ve been good at measuring volume: clicks, visits, impressions, registrations, etc. We have also been really good at measuring velocity: time on page, click-through rate and so on. What Big Data can add to the picture is really very simple -- it adds a measure of value. So that next time a goal for a webinar would be not to get 1,000 registrations, but to attribute to say $1 million in revenue.
The concept of affiliate marketing on the Internet was conceived of, put into practice and patented by William J. Tobin, the founder of PC Flowers & Gifts. Launched on the Prodigy Network in 1989, PC Flowers & Gifts remained on the service until 1996. By 1993, PC Flowers & Gifts generated sales in excess of $6 million per year on the Prodigy service. In 1998, PC Flowers and Gifts developed the business model of paying a commission on sales to the Prodigy Network.
