You can run ads in affiliate marketing without a landing page. Some affiliate marketers use direct linking to send traffic straight to the offer page. You can use this method if the affiliate program allows it. You can also promote affiliate products using social media or paid ads. These platforms let you link directly to the product. You may get better results with a landing page. A landing page helps build trust and capture leads. Without one, your conversion rate might be lower. You can still succeed but having a landing page is often more effective.
