One landing page can be enough for CPA offers. You focus on creating a high-converting page that targets your audience's needs. You use a strong call-to-action and clear value propositions. You keep the design simple and easy to navigate. However, as you scale, you may need more landing pages. You test different versions to see which one performs best. You create separate pages for different traffic sources or offers. You also segment your audience to provide a more personalized experience. One landing page can work, but continuous testing and optimization are key to increasing conversions.
