Usability testing is a technique used to evaluate a product by letting users try its features for free and record the process while doing it. This usability exercise gives direct information on how real users use a system and shows if its features are user-friendly or perhaps need some work. This type of testing can be used to assess features of websites, apps or various devices.
You can also use an all-inclusive ecommerce web service. Sites such as Shopify and Volusion offer competitive packages, with free templates, custom packages, credit card processing, and more. Ecommerce web services makes it easy to sell your products on the web, without a lot of overhead. There are no custom interfaces or templates to work with; you simply create an online store within the framework of the service.
Blogging is a great side hustle because you can do it at your own pace anywhere you want. It's not a quick and easy way to make money, but there are a lot of ways to make money side hustling while blogging. You can sell advertising, become an affiliate for other people's products, sell your own online product, and more. It does take time to build up an audience to be able to make a decent amount of money, but once you have a large following, you could earn over $15,000 per month or more (we do).
