Regarding “convincing someone to buy your product is not that easy”, I do agree with you, but at the same time, I remember all those products I’ve bought online. I did not search on Google for those products neither I went to the company websites to get information and buy. They were affiliate people and their blogs that inspired to buy them. PrettyLink Pro, SEO Pressor was recommended by Kimberley, I bought Profits Theme, WP Zon builder because Alex Whaley recommended. Similarly I bought CommentLuv Premium because Ileane, Kavita, Steve and many others were talking good about it.
From there, results vary over time. Successful affiliate sites are updated regularly, have a clear focus that excites visitors, provide lots of useful content, and many affiliates find the their highest referrals when they invest in advertising as well. I generally write one 1,000 word article per day (minimum of 5 per week) on new sites and it usually takes at least 6 months before I earn my first cent. Most of my sites don’t start earning the ‘job quitting income’ until a couple years after I start them. You can learn more about how long it takes to succeed in affiliate marketing here.
Many affiliate programs run with last-click attribution, where the affiliate receiving the last click before the sale gets 100% credit for the conversion. This is changing. With affiliate platforms providing new attribution models and reporting features, you are able to see a full-funnel, cross-channel view of how individual marketing tactics are working together. For example, you might see that a paid social campaign generated the first click, Affiliate X got click 2, and Affiliate Y got the last click. With this full picture, you can structure your affiliate commissions so that Affiliate X gets a percentage of the credit for the sale, even though they didn’t get the last click.
