Soundproofing a room in your home is a popular search term on Google, and there are TONS AND TONS of products you can recommend and link to Amazon for people to buy.  And you’ll earn 8% of the products they buy after clicking your affiliate link to Amazon.  The best part of it is that the products are often in the $200 range, which I find to be a sweet spot for Amazon Associates.  It’s enough money that you get a good commission, but not so absurdly expensive that people won’t buy.
It’s very complicated to figure out what you need to get voice, data, and texting back on your phone in another country without racking up huge bills.  Each country is different.  Some countries you need to get a local SIM, some countries you just need to call your cell provider and turn on international data, some countries just don’t have good enough service to make it reasonable to use a phone, etc.
I am confused about the keywords in the spreadsheet. For example, there is a keyword “oxford shoes for kids” that shows really low competition in the spreadsheet, but obviously there are many seller in there. So it would appear the data returned by junglescout is incorrect. Searching the same keyword on the web app returned same data as the spreadsheet, so it’s not a spreadsheet problem. Any explanation for this?
The compensation plan offers as much as 80% commission, which is more than most other sites in this field. There are plenty of different ways for affiliates to promote the company, including banner displays and contextual ads. The site is also very well designed. It looks professional, modern and exciting, which should encourage signups. Of course, you are targeting a narrower audience than with some other dating sites.
Twitch’s affiliate program offers individuals the ability to earn revenue, while streaming. The platform focuses on standard video game streaming first, but includes coverage of the rapidly growing competitive eSports industry as well. Becoming a Twitch Affiliate enables streamers to earn as long as they stream on a frequent basis, with the option to accumulate revenue from the sale of games and their in-game items. They may also earn via ‘Bits’: virtual goods that viewers can offer, resulting in a share of the revenue for the streamer. 

1. The batting cage idea is very risky. I’ve seen many of them close over the years and it is not anything close to passive income if you want to keep the business going. You have to continually promote it and target youth leagues, coaches, schools etc to catch all of the new players who grow up and want to play. I’ve played at probably 8 batting cages over the years and 7 of them closed.
You need to decide which machines you want to run, get the necessary licenses to operate them (you're selling items so you need to get sales licenses and whatnot from your state), buy the machines and a truck for the items in the machines, find a supplier of the products, and then finally you can secure locations. Finally, you need to service them periodically or hire someone to service them.
For example, you can design digital products, like animal clipart or a downloadable wedding poem that could be printed by the customer. Your design could be resold thousands of times without needing to create each item or ship it. Once you create your digital product and list it on a site like Etsy or Ebay, the revenue flows in with little oversight.
