More website visitors won't fix a broken landing page. Focus on conversion rate first: make your offer clear and compelling, streamline checkout, then scale traffic. Every visitor becomes valuable when the fundamentals work.
Here's some food for thought. Maybe sometimes you don't need more traffic. Maybe you need better conversions. More traffic to your website, more traffic to your landing pages might not be the solution right now. More traffic won't save your business if your landing pages and your website don't convert. So my feedback to you is focus on the journey. Ask yourself these questions: is your landing page clear? Is your offer irresistible? Is your checkout process smooth? If you fix these first, then every single click that you get will matter. At the end of the day, traffic without conversions is just expensive noise.
