Allow readers to purchase your own products or donate to your cause through your blog. If you have an online store for selling arts and crafts, or you create T-shirt designs available through a clothing website, provide links to those sites. Including a PayPal button for quick, safe purchases or donations is a common way to monetize creative blogs, or blogs that provide free advice or assistance to those who can't afford it.
Creating a job board on your site is a great way to make your blog "sticky" - meaning you get visitors returning again and again. It's also a great way to earn some extra cash while also providing a valuable service. Darren Rowse from ProBlogger runs a hugely popular job board where he charges $70 for a 30-day listing. With around 70 listings per month, he's bringing in some solid earnings with relatively little investment of time or money.
Once you setup your account on AdSense you will be given a code to add to your blog. This code will automatically display advertisements on your blog from companies who are part of Google’s advertising network. You may see ads from small companies related to your topic, or you may see ads from large companies that are completely unrelated to your topic.
