They often expect you to commit to working a certain number of hours per week, which is generally part-time. They will pay you an hourly salary for that work, so it is really more of an at home job situation than it is in an entrepreneurial way to make money online. Still, if you want to get involved in political activity, and you have the time and motivation, this could be a way to monetize that passion.
You can also market your ebook on your own website or blog, particularly if the site gets good traffic. Still another method is affiliate marketing. You can offer to pay sites related to your ebook a percentage of the sale price – say, anywhere between 20% and 50% – for them to post an ad or linked article for your book on their site. This could enable you to market your ebook on multiple platforms for greater market exposure.
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.
