Affiliate marketing validates niche demand before creating your own product

Use affiliate marketing to test your niche before investing in product creation. Join Amazon's affiliate program or similar programs to see if you can sell existing products in your chosen market. If you can drive traffic and conversions as an affiliate, you've proven that demand exists and that you can reach the audience — before you've spent a single hour building your own product. This is one of the fastest and cheapest validation tests available. The market's response to affiliate offers tells you more than any survey because it requires real money to change hands, which is the only true signal of buying intent.
