What are the three benefits of having more leads?

The question should be more, what are the benefits of having more "quality" leads? Getting more leads is very much profitable for a business. It helps in getting more ROI, getting more customers, and Increasing the conversion rate.

However, having more quality leads does not happen in one day. It requires extensive knowledge of marketing and sales. If you are just going out blindly to promote your business, it wouldn't sustain it for very long.
