Will my target audience realistically spend this amount for the product? Again, your reputation is on the line here. Is the product you are thinking of promoting priced reasonably for your audience? When I was writing my ebook, I was stuck on pricing. I asked around for opinions. A number of people suggested I price my ebook at $47! Their idea was to price according to value, not size. In my mind that was crazy. My network was composed of a lot of stay-at-home bloggers, and my collective audience was comprised mostly of people without a whole lot of disposable income. There was no way anyone was going to pay $47 for my 30-page ebook.
So, a program that promises you anything outrageous should send you immediate red flags. Secondly, the best affiliate marketing training programs offer comprehensive support. Most people starting out in affiliate marketing do not have any formal training in web design, sales and marketing, and content creation.

StackPath – CDN with 31 additional data centers (Cloudflare has 150+ data centers, but more data centers = faster content delivery).

Cost per mille requires only that the publisher make the advertising available on his or her website and display it to the page visitors in order to receive a commission. Pay per click requires one additional step in the conversion process to generate revenue for the publisher: A visitor must not only be made aware of the advertisement but must also click on the advertisement to visit the advertiser's website.
While your site is still new, it's a good idea to start capitalizing on someone else's audience. Continue focusing on building your own content, but also considering writing content for a few big, high-traffic blogs that are relevant for your niche. By writing content for a bigger site, you are able to get in front of another audience and showcase your expertise on a particular topic. This will eventually lead to more traffic to your site, as well. 
Always disclose your affiliate relationship. Most visitors will probably understand that graphic ads will lead to your getting paid, but if you write a review or use an in-text link as a recommendation, you want your readers to know that may lead to compensation as well. This ensures you retain transparency and trust with your readers, but also, it's required by the FTC's endorsement rules.
