Considering that you have a finite amount of time, passive income should make up a large part of your work. If you're serious about generating any semblance of income online, then passive income should be one of your sole goals and ambitions. Why? Wouldn't you prefer to do the work one time and get paid repeatedly as opposed to relying on your time to generate that income? Invest the time at the front-end so that you can reap the benefits on the back-end. This means putting in a bit of sweat equity and not getting paid today. Rather, you'll get paid somewhere down the road. And you'll continue getting paid whether you keep building that passive income stream or you stop.
Banners – after testing them out I decided to take down my banner ads since they looked salesy and weren’t working like my affiliate links did. They’re easy to throw up, but distracting and probably won’t get great results. If you try them, be sure to show specific sidebar banners based on the type of content people are reading on your blog (for posts that fall under my SEO category I would show a banner related to SEO, and for posts under my website speed category I would show a different banner). You can do this using a plugin like Widget Logic.
Create custom alerts on your phone for affiliate sales – if you use GMail, go to your settings and create a filter so all emails with “SiteGround Affiliate Sale Generated” in the subject line go into their own folder (tweak the subject line to match whatever email notification your affiliate sends you). Then setup a custom alert on your phone using the GMail app so anytime you generate a sale, you get a custom alert (here’s a tutorial for Android and here’s one for Apple). I have different notifications for SiteGround, StudioPress Themes, etc. Makes your day better :)
28. Subscription – If you think of something valuable (newsletter, online magazine, etc.) that you can consistently offer on a certain basis (weekly, monthly, etc.), you may want to offer a subscription service. This could be a fee charged each time your product is sent out or on a monthly basis. Either way, this has to be something that your customers can only get by subscribing to your website.
Take good pictures. Some of the options below don’t require you to actually take the picture and sell the product, but for the ones that do, make sure you take a clear picture that makes your product stand out from the others. If you’re going to be taking a lot of pictures, set up a small “studio-like” area in your home with a backdrop and proper lighting to really make your pictures come across as professional. And of course, you’ll want a good camera too.
