Now, this isn't about some get-rich-quick method here. If you want to get rich quick, forget about trying to do it on the internet. Sure, Facebook ads are all the craze, but without a serious understanding of the mechanics behind sales funnels and conversion optimizations, which only comes after years and years of in-the-trenches work in the internet marketing field, you're largely wasting your time trying to "get rich quick."
Building a strong mailing list is always a useful asset to any blog as it helps build your readership. You do not have to rely entirely on social media shares and search engine rankings. People will keep visiting your site long after their first visit, if they sign up for weekly or monthly newsletters. Most sites with a loyal readership have fat email lists.
Swap.com. Like ThredUp, it's an online consignment store. You send in used clothes (women, kids, men's) and kids toys and games, and Swap will sell them for you. Hopefully. They may reject them, in which case you'll either have to pay a fee to get your things back or donate them. But assuming you're sending in clothes and toys that people will want to buy, your odds of selling them should be good. The website says that "sellers, on average, earn about $150 per box they sell on Swap.com when sending in-season, high-quality items." Especially note the words, "high-quality."
Something I’m experimenting more and more with and I’m not sure if it’s just me.. but it seems like the world has gone crazy about making products, they are everywhere which has educated the market so they know they have to purchase content now. The simple version of creating a product is as followed, create a 30+ page word document about something, turn it into a PDF and sell it.
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.
