You can create your blog using a free platform from WordPress.org, but you’ll need to pay a small amount – as little as $4 per month – to have your blog hosted. Try GoDaddy.com, which can provide a domain name for your site, email addresses, database storage and other Web hosting services. To make money, you can use the free Google AdSense service to display advertisements on your site. The amount you’re paid varies by ad and usually depends on how many people see it. There's also what's called affiliate marketing, in which you earn a commission (usually less than 10%) whenever someone clicks on an ad on your site and purchases a product. The Amazon Associates affiliate program allows you to advertise the retailer’s products on your site, or try affiliate networks such as CJ Affiliate or ShareASale that work with thousands of companies. Depending on how much time you put into your blog and how many people visit it, you could be making a few hundred dollars each month within a year.
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.
