Conversion rate is an indicator of all the efforts you are giving to drive clicks to your website. Optimizing your conversion rate requires deliberate and efficient efforts. Having the right conversion rate optimization tools can help you streamline your efforts and drive more revenue.

Conversion rate is the percentage of website visitors who fulfill a targeted goal. These goals can range from filling out a form to making a purchase. If your conversion rate is high, it means your campaign is successful in converting leads. A poor conversion rate implies that it needs optimization.
