When picking a niche for affiliate marketing, the monthly search volume matters because it shows how much interest there is in a topic. A good starting point is aiming for a niche with at least 5,000 to 10,000 searches per month. This range often means there's enough people looking for products or information, so you have a chance to earn commissions without competing in oversaturated markets. However, it's not just about the numbers. You should also check if the niche has products people are likely to buy and if those products offer decent affiliate payouts. A smaller niche with high buyer intent can sometimes be better than a huge one with low profits. It's smart to use tools like Google Keyword Planner to get a sense of search trends. Then, test the niche to see if it works for you. What are your thoughts on this?
