If your conversion rate is too low, you need to diagnose why it is so low. Use your analytics system, to help get insights into why it is low.
Some metrics to look at could be:
- Conversion by traffic source, and conversion by traffic source by device
- Conversion by geography
- Conversion by time of day
- Conversion by piece of content, or URL/internal source
These should help you find where air is potentially leaking from the system – and in turn decreasing your overall conversion rate.
Another thing to do, is ask yourself. Is the conversion action itself reasonable? Maybe the ask is too much upfront. Or the process itself is too onerous. Consider making the conversion actions easier and more streamlined for users to complete.
