Now as to your comment on traffic it is true, traffic is important. But the truth is, acquiring traffic is easier than converting it. Plus we have many posts dedicated to traffic generation on this blog. Simply check this post, this post or this post. But must importantly, the reason why people struggle with traffic is that they try to promote a sales page or a heavily biased piece of content. Nobody wants to share that, nobody wants to link to that, and as a result you don't get traffic and blame your lack of success on traffic (like you did in your comment above).
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.

Don’t exhaust all the information about the product with your link. Offer enough information to your readers so they know what the link is, but I don’t recommend giving too much detail on your own site for a two reasons. First, product information, like price, often changes. If you mention the price on your site and someone clicks over and finds a different price, it’s confusing. Second, many times, the product details and features are better explained by the makers of the product. It’s best to stick to your own experience on your site.
Many affiliate marketers use paid advertising to generate additional traffic to their site and drive more sales. Paid advertising on social media is often a good place to start, as these networks tend to be more affordable.You may also want to consider taking out inexpensive banner ads on small niche sites. Depending on your niche, Google AdWords could also be a good option to drive some paid traffic to your site.
After being accepted into an affiliate program, marketers receive a unique URL that includes their affiliate ID. They share that unique URL with their subscribers, site visitors, and social networks via text links or ads. When someone clicks on that link, affiliate software records that click and any resulting product sales in the affiliate’s account. When commissions reach a pre-determined threshold, the affiliate is paid.
