Direct linking: This means you’ll send people directly to the vendor’s sales page. This used to work well and still does in some rare cases but most of the time, it’s not recommended to go down that route. You need to “warm up” your visitor first before sending them to the offer page. Unfortunately, because this is the lazy man’s route, a lot of people choose it.

The topic you choose must have enough depth that you can create a lot of content for it. This is important for building an authoritative site, for search engine optimization, and most importantly, for the end user. If you don't have enough content about a topic, you're not going to be taken very seriously as an authority on the topic and it's unlikely you can convince someone to make a purchase from you. 

Two-tier programs exist in the minority of affiliate programs; most are simply one-tier. Referral programs beyond two-tier resemble multi-level marketing (MLM) or network marketing but are different: Multi-level marketing (MLM) or network marketing associations tend to have more complex commission requirements/qualifications than standard affiliate programs.[citation needed]
Like virtual assistants, proofreaders can find jobs with almost any business that publishes content online. They provide a second set of eyes for publishers, and can help them create content that looks more polished and professional. Those with specialized skills, like transcript proofreading, can also find work proofreading transcripts for court reporters.
Very high commissions: Most ClickBank products pay 70%+ commission. You read that right. So in that case, if you sell a $100 product, you earn $70. You might think that’s way too high to be real, but it is. They’re mainly able to do that because most of their products are digital, which means there are no “production” costs, “shipping” costs or any other costs that are usually associated with physical products, hence the high commissions.
One big difference between SkimLinks and VigLinks, however, is that once you’re approved by the company, you can choose to work with any merchant or program on its platform. SkimLinks has also published a white paper discussing its partnership with Buzzfeed, giving SkimLinks a lot of credibility. SkimLinks also has a higher tier of vetted merchants called “Preferred Partner” and “VIP” that both pay higher commissions than standard merchants.
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.[33]
