Apply scientific method to your marketing.
- Form a hypothesis ("changing the call to action will increase the number of signups by 40%")
- Test it (do split testing on 2 pages so you could compare the results)
- Analyze the outcome, use it to adjust hypothesis, come up with more experiments, and get better at predicting the outcomes.
This will make your progress way more strategic and effective. You can come up with multiple hypothesis, and test the most promising ones first.
