@lamb7 You can do everything every CRO/copy expert tells you to do and still not convert users. Because converting users doesn't only depend on the website message. It depends on the product, pricing, positioning and so many other factors.
And, no, you don't need resources to pull this off. Follow the right people who give this advice for free.
Also, there are sites like CXL, Copyhackers and marketing examples. They have so many examples, all free.
Trust me, you don't even need to hire a copywriter if you don't have the budget. Just start with these sites, read the case studies, implement basic changes and see what works for you.
