By promoting 21BOOM, you hereby agree to the following terms of service. If an affiliate breaches the following terms, they will be instantly banned from promoting our services.

1) Disclosure

This is a statement you make informing your readers that you use affiliate links on your website. 

To comply with FTC laws, you need to have this disclosure somewhere on the page where you use affiliate links. You want to place this statement towards the top of your pages before you mention your affiliate offers. 

You should also have a Disclosure page where readers can learn more about how you make money from your blog.

2) First-click attribution

This means that the affiliate program will allocate commissions to the affiliate who was the first to refer the customer who made a purchase within their cookie duration.

3) Last-click attribution

Programs using the last-click model attribute the sale to the affiliate whose link was the last one that the customer clicked on before making a purchase.

This means that though your referral could still be within the agreed cookie duration, you will not earn a commission if they clicked on another affiliate’s link and ended up purchasing the product. 

The last click is awarded the commission.

4) Earnings Per Click (EPC)

Earnings per click is the average amount an affiliate earns for each person or visitor that clicks on their advert to go and buy from a merchant’s website. 

It’s usually calculated as the overall earned commissions divided by the number of clicks over a particular period. 

For example, if 100 people clicked through to your merchant site, and 5 of them ended up making a purchase that earned you $100 per sale, then your average EPC is $500/100, which equals $5.

5) A/B Testing

 A/B testing refers to the process of simultaneously running two or more versions of a webpage – with variable content or design elements and tracking different key metrics so as to identify which version is the most effective at achieving the intended goal, be it clicks, conversion or subscription.

Affiliates can use this method to test which creatives will provide them with the highest conversion rates.

6) Affiliate ID

This is a unique identifier provided by affiliate networks to identify affiliates who are members of their program. Usually, this is a username or a number assigned to the affiliate by the affiliate software.

7) CTA: Short for Call to Action

CTAs are used in advertisements and marketing materials to encourage the reader or viewer into taking a specific action. Usually, these are links or buttons that lead to the affiliate programs.

8) Two-tier affiliate programs

An affiliate program that also features a tiered commission structure. Affiliates earn commissions on the sales of other affiliates they refer, as well as on their own sales.

9) Advertiser

Advertisers are the merchants with products. They pay affiliates to promote their products through influencer marketing, where compensation is commission-based.

10) Affiliate/Publisher

This is you. You promote other people’s products as an affiliate and earn commissions when people take actions such as making a purchase or signing up to a list.

11) Affiliate Network

This is an affiliate marketplace that brings merchants and publishers together. 

The affiliates can choose which merchants they want to promote. They then apply directly through the program, and the merchant can either approve or disapprove affiliates.

Examples of affiliate networks include:



Impact radius

Rakuten Advertising

Commission Junction (CJ), etc.

Affiliate networks act as intermediaries between affiliates and merchants, providing affiliates with access to products and services from a wide range of merchants. 

12) Conversion

This is an event generated by a user that the merchant is willing to pay for. This can be clicks, leads, or sales

13) Conversion rate

A conversion rate is the percentage chance that an online user takes to purchase what they found after clicking on one of your affiliate assets.

14) Lead

Think of this as a contact that has the potential of becoming a buying customer to your merchant. 

There are affiliate networks specifically made for call leads.

15) Deep linking

This is a feature in your affiliate network or program that enables you to generate an affiliate link to any page or post on your advertiser’s website. 

These links are called custom affiliate links.

For instance, you may want to point to a guide instead of a product but still want to get attributed if a person ends up taking action on the merchants’ websites. 

Not all programs allow you to create custom links, though.

16) Tracking link

Also known as the affiliate link. 

This is the unique link that leads to the offer and attributes you as the referrer. You will use this link when promoting your partner’s products.

17) Above the fold

This refers to the section of your website which is visible upon loading the page without one having to scroll. 

Here, make sure you place your most converting opt-in offer or a banner of your relevant and high-performing affiliate product.

18) Pay-Per-Sale

Affiliation model that only earns you a commission for every sale you make

19) Pay-Per-Lead affiliate programs

A pay-per-lead is an affiliate advertising model where affiliates are compensated when they generate a non-sale activity. Examples of such activities include:

Subscribing to an email list


Starting a free trial

Making an inquiry

Booking a meeting

Checking loan eligibility, etc.
