Running a coupons website can be very lucrative. Find a coupon niche, select a WordPress coupon theme, and then display relevant coupons on your site. When your audience uses the coupon codes or discount links, you will earn an affiliate cut for example you could set-up a site dedicated to iHerb Coupons or add a page to your website with Web Hosting Promo Codes. Coupon websites are quite high maintenance as they need to be constantly updated with new offers. However, if you build up an engaged audience and allow them to post coupons and discounts they have found themselves, then quite quickly your workload will reduce.
You may decide to create free videos as extra content for your blog, and not sell them at all. If this is the case then you can still make money from these videos by selling advertising space on them (in the same way as discussed for monetizing podcasts). Once you have high volumes of traffic visiting your blog, and watching your videos, you can charge businesses to advertise at the beginning of your videos. Use website’s like Izea to help you connect with companies willing to pay to advertise on your blog.
Offering specific online SEO services is also another online freelancer role that businesses are crying out for. If you know how to improve a website’s SEO by doing keyword research, creating content that can rank in search engines, adding metadata / schema to posts and pages, and building backlinks to a domain, to name a few tasks, then this could be a great line of work for you.
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.
