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.
Using Fiverr is a great way to pick up work. Once you have signed up you can advertise your services. Fiver allows you to create your own gigs, whether you are offering web design, digital marketing, writing, or something else. You can choose how much you want to charge (it can be more than a fiver) and people will then contact you if they are interested in working with you. Fiverr will not only help you get experience if you are just starting off as a freelancer, it will also help you earn some extra cash.
