If you manage to rank at the top of Google, the best strategy isn't just about "easy money" keywords, it's about targeting what are known as "buyer intent" keywords. These are queries where the person searching is very close to making a purchase.
Examples of these keywords include "best [product] for beginners," "[product] review," "[product name] vs. [competitor name]," or even "cheap [product] for sale."
These keywords show that the user is no longer just looking for information, but is actively comparing and evaluating options before they buy. This kind of traffic is the most valuable because it has the highest potential to convert into a sale.
As for affiliate links, you should look for products or services that fit naturally into the content you're creating for those keywords. For example, if your content is a review of the "best noise-canceling headphones," your affiliate links should lead to those specific headphones on a site like Amazon or a direct merchant site. The most profitable affiliate programs often offer high commissions on digital products, software, or high-ticket items.
Look into platforms and networks that specialize in these areas, as they often have a higher payout per sale compared to physical goods. The key is to provide genuine value and honest recommendations to your audience, as building trust is what ultimately leads to conversions.
