Hi Akshara – You’ve given a lot of good advice. Though a home business seems easy (but yes, they ARE easy to start), it’s first and foremost a business. That means you won’t be an overnight success. It could take years before it earns enough money to live on. It might be best to start it as a side business. But always remember to run it as a serious business, and not as a casual hobby. One other thing about a business…the hardest part is getting it from zero to making money. You have to be willing to overcome that hurdle.
Who is your audience? What is your target market or niche? If you're targeting a specific niche like home security then perhaps you only need to sign up to ADT and SpyBase so your products match your audience. There’s no point promoting eco-mattresses to your blog that’s focused on reviewing drones. Again, you could sign up to a network that has a few different options in your field of interest or just go straight to your favourite suppliers and see if they have an affiliate program.
