These mega-sites make it easy to set up shop so customers can browse your products, and there's no need to build your own website. Also, you’ll find a built-in search feature so that interested buyers can easily find your online storefront. Plus, you get to use the site's shopping cart. In short, you avoid a lot of the expense and hassle of setting up an independent e-commerce website.
One of the cool things about Google AdSense is that it's so easy to get set up. If you have a blog or website, you can sign up for a free Google AdSense Account. From there, Google will give you a unique code that you will paste onto your website. Google takes it from there, tracking your page views, traffic, and earnings on your behalf. There is no upkeep or maintenance to get this thing going, which makes it a no-brainer if you have a website already.
