Let no one tell you that email marketing is dead. An email list is crucial for every affiliate marketer. You can start building up your email list with a lead magnet (like the information products mentioned previously) or even just by encouraging your audience to sign up for your updates. You can then push your content to this audience via email and also direct them to your affiliate offers. Don't be sleazy about the sales, but if you build up enough trust with your email audience; when the time comes, they will not mind purchasing a product from you. 
An affiliate marketing program is a lot of work, and in most situations there's a lot of competition so you're not going to be bringing in money immediately. Business owners and entrepreneurs suppose that all you need do is setup a site and choose an affiliate to associate with and then just let it run its course. But according to Three Ladders Marketing, only 0.6% of affiliate marketers surveyed have been in the game since 2013. That means that affiliate marketing takes time and effort to build and make money.

The first mistake a lot of affiliate marketers make is that they register with too many different affiliate programs and try to promote everything. Pursuing affiliate marketing down this path can become very overwhelming and you won’t be able to promote any product properly. All you need in order to be successful is a handful of good products to promote. Try to understand the market needs and look for products that align correctly with the topic of your site.
What struck me about Dr. Rose’s experience was how affiliate marketing attracts everyone — from those with no degrees (but with strong work ethics), to those who are fully degreed (and pedigreed), but who want to do their own thing. Dr. Rose stated in that post that her mission was to earn what she earned as a pharmacist in a year — in one month in affilite marketing/blogging.

The General Data Protection Regulation (GDPR), which took effect on May 25, 2018, is a set of regulations governing the use of personal data across the EU. This is forcing some affiliates to obtain user data through opt-in consent (updated privacy policies and cookie notices), even if they are not located in the European Union. This new regulation should also remind you to follow FTC guidelines and clearly disclose that you receive affiliate commissions from your recommendations. 
Spam is the biggest threat to organic search engines, whose goal is to provide quality search results for keywords or phrases entered by their users. Google's PageRank algorithm update ("BigDaddy") in February 2006—the final stage of Google's major update ("Jagger") that began in mid-summer 2005—specifically targeted spamdexing with great success. This update thus enabled Google to remove a large amount of mostly computer-generated duplicate content from its index.[28]

I literally went from $20k/year to $150k/year in 2 years – see my 2018 income reports. I did this by dropping my web design/SEO clients and tried to make money with affiliate marketing (I write SEO/speed optimization tutorials). 90% of my affiliate income comes from SiteGround, a hosting company who awarded me affiliate of the month in July, 2017 when I made $9k in 1 month. Since then I have continued to hit numbers like this – the screenshot below is from March, 2018 when I made $14.5k in 1 month (just with SiteGround). I have other affiliates too.
