If you're serious about making money online, start a blog. Blogging is one of the easiest and most sustainable income sources. As long as the blog is setup the right way, in the right niche, with the right content targeted at the right audience, and the offer is complementary to the content, you could make a tremendous amount of passive income from a blog.
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 :)
