Cost per Lead (CPL) is the average amount spent on acquiring a new lead, inclusive of all marketing channels such as paid advertising, social media campaigns, and content marketing. Cost per Lead (CPL) is a crucial metric that helps businesses measure their marketing campaigns' effectiveness in generating leads. CPL is calculated by dividing the total cost of acquiring new leads by the number of leads generated. This metric is particularly valuable for businesses that want to optimize their marketing spend to maximize return on investment (ROI). Marketing teams can segment CPL by channel. For instance, they may focus on paid advertising and consider only the inputs relating to paid ad costs and leads generated. It's important to always include the right costs in your equation, especially if salaries, creatives, or equipment are the main drivers.

Domain Authority is a score developed by Moz that predicts how well a website will rank on search engine result pages (SERPs). DA is not an authority metric used by Google in determining search rankings but, instead, a third-party tool used for benchmarking and competitive link analysis. It is also a relative measure, meaning that it is most useful when comparing one domain's authority to another rather than as an absolute score of a website's traffic and performance.

Email Bounce Rate is the percentage of emails that have not successfully reached recipients. An email bounce occurs when a sender receives a Non-Delivery Report (NDR) for an email. The number of email bounces divided by the total number of emails sent gives the Email Bounce Rate.
