No. Once you pass your test, and receive your certificate, you are certified for life. For instance if do great on your exam, and thereby get your SEO Certification, get Web Analytics Certified or a Social Media Marketing Certification, then you have it, and we will not ask you to give it back to us, or remove it from your LinkedIn profile, CV or resume. Once you pass the test, the certification is yours to keep.
Before jumping into starting an affiliate marketing business, learn all that's involved in making it a success. More importantly, if you decide to pursue an affiliate marketing business, or want to add affiliate marketing to an existing business, understand that it's not fast, automatic, nor without effort. Like all home businesses, you need a plan and daily involvement to make money with an online affiliate marketing.
Affiliate marketing is also called "performance marketing", in reference to how sales employees are typically being compensated. Such employees are typically paid a commission for each sale they close, and sometimes are paid performance incentives for exceeding objectives. Affiliates are not employed by the advertiser whose products or services they promote, but the compensation models applied to affiliate marketing are very similar to the ones used for people in the advertisers' internal sales department.
