The 8 Best Lead Generation KPIs for Managing Your Business

There is a wide seam of advisories and information pieces that guide marketing and sales teams in planning, executing, tuning, and reviewing lead-generation efforts and expenditures. Some of these advisories describe as many as 15 or more key performance indicators (KPIs) that can be used to assess success in terms of return on investment (ROI). Many of these can be differentiated additionally, to refine more indicators that can be useful.


This article will explore eight KPIs that can be applied to deliver optimization of lead-generation assessment.

Number of Sessions

The number of lead-generation sessions refers to the number of unique events or sessions undertaken to attract and capture potential leads or prospects. It is the key to initiating lead generation and assessing the effectiveness of the process. The session count can include a wide spectrum of engagement activities, such as: webinars, seminars, workshops, online events, trade shows, and digital marketing campaigns.

The number of lead-generation sessions is measured over a regular time frame to facilitate easy comparison between recording periods. This equips organizations to assess how frequently they engage with their target audience in creating opportunities for lead generation. That in turn offers insights into the level of activity and the variety of channels used to generate leads. 

A higher number of recorded sessions points to an active and dynamic marketing strategy. However, effectiveness should also be assessed by tracking the outcomes, generated by evaluating conversion rates and the quality of leads obtained. This avoids being distracted by the volume of activity over the quality of outcomes.

By monitoring this metric (adjusted for quality), businesses can make better-informed decisions about resource allocation to create better ROI. Identifying which lead-generation channels or events are the most productive creates better targeting in the allocation of resources. Consistent and methodical tracking of the number of lead-generation sessions allows organizations to optimize marketing efforts, refine messaging, and adapt strategies to evolving market conditions. This can be informed and adjusted by A/B testing, with potentially fast measures that allow agile revisions.

Lead-generation sessions play a crucial role in priming the sales funnel with potential, and most desirably, high-value customers. The number of sessions directly impacts the top of the sales funnel. Organizations optimally set targets for the number of lead-generation sessions to align with their broader marketing and sales objectives.

Number of Leads

The number of leads measures the number of potential customers or prospects who have expressed interest in a product or service. The number of leads is typically tracked over a specific calendar period. It can also be segmented by lead source or marketing channel to pinpoint the most successful strategies and measure the effect of systemic adjustments in methodology. This reflects the success of a marketing campaign, lead-generation activity, or overall customer-acquisition effort. The quantitative measure of how well a business is expanding its potential customer base is powerful in both performance evaluation and in assessing the effect of alterations in strategy.

While the number of leads is important, it's equally crucial to assess their quality. Not all leads are created equal; the probability of conversion into paying customers can be widely variable. Therefore, tracking lead quality alongside quantity is essential for a meaningful and informative evaluation. The number of leads generally closely correlates with the conversion rate. A high number of leads with a low conversion rate necessarily indicates issues in the effectiveness of the processes and materials employed in the upper end of the sales funnel.

Monitoring the number of leads helps in the effective allocation of marketing resources. It can guide decisions about budget/personnel allocation, marketing-channel selection, and sales collateral development. Marketing teams should seek to compare their lead-generation performance to industry benchmarks or historical data to assess their competitiveness and identify areas for systemic, methodological, or collateral changes. Organizations must set specific lead-generation goals, aiming to meet their growth targets and better their historical performance. Tracking the number of leads helps measure progress toward these objectives.

Number of Conversions

The number of conversions evaluates the success and ROI of marketing, advertising, and sales campaigns as a whole and in their parts. Conversion is typically interpreted as a predefined engagement action taken by a customer or prospect. This might be making a purchase, signing up for a newsletter, or completing a contact data form. This KPI is pivotal for any marketing team looking to measure their effectiveness in conversion-focused strategies and optimization of their sales funnel by feedback.

This tracks the total number of completed conversions over a defined period that suits the nature of the campaign. Conversions can vary considerably in type, based on business objectives. These might be lead-generated sales or website engagements. Businesses and marketing teams typically set specific conversion goals aligned to strategic revenue objectives. For e-commerce companies, conversions can be considered as online purchases. for lead-generation campaigns, conversions may represent events like form submissions or sign-ups.

The number of conversions is crucial in assessing the performance of the various distinct stages of the sales-funnel journey. The metric helps identify which steps in the customer journey are most effective at converting prospects into revenue-generating customers. This measure is paired with some form of conversion-rate metric to gain a more all-encompassing understanding, providing insights into the efficiency of conversion efforts.

Tracking the recorded quantum of conversions allows businesses to evaluate the return on investment (ROI) of a campaign. It also tends to identify the marketing channels, strategies, and campaign elements that deliver the most valuable results. By monitoring these metrics, a marketing/sales team can make data-driven decisions to optimize their marketing strategies, improve website UX, refine ad campaigns, and enhance the customer experience to drive more conversions. This should be a continuous improvement process that remains attuned to outcomes and aware of the effects of strategy and content adjustments

Conversion Rate

The conversion rate is a crucial metric that precisely informs about the effectiveness of marketing and sales efforts, by measuring the conversion of potential customers or leads into actual buyers or action-takers. It measures the percentage of individuals who take a predefined action or actions, such as making a purchase, signing up for a newsletter, or completing a form, as a percentage of the total number of visitors or leads.

Conversion rate is calculated by dividing the number of conversions (desired actions/outcomes) by the total number of visitors/leads/opportunities and then multiplying by 100 to express it as a percentage.

Conversion rate is a fundamental KPI because it directly and precisely informs the efficiency of a sales- or marketing-funnel process. It provides insights into how well a business is performing in persuading and converting potential customers to grow/maintain revenue and profitability. It can apply to diverse types of conversions, depending on the business's goals and pre-agreed priorities. Such measurements might be for: e-commerce sales, lead-generation form submissions, content downloads, or email sign-ups.

To gain a more nuanced understanding, the conversion rate can be segmented by: traffic sources, devices, demographics, or a variety of other factors of interest. This helps identify channels or audience segments that are performing at, above, or below their target level, which can drive process adjustments and altered prioritizations. Businesses often benchmark their conversion rates against sector norms or their historical data to assess competitiveness/development and identify areas for improvement. A higher conversion rate is, of course, desirable and can generally be influenced by: A/B testing of methods/channels/content changes, website improvements, ad-campaign refinements, and personalized content to influence the rate.

Conversion rate is directly related to ROI in marketing and sales efforts. It drives the allocation of resources to greater effect and determines which strategies deliver the better return. In lead generation, the conversion rate directly measures the success rate in nurturing leads through the sales funnel. Improving this rate ensures that more leads progress to the final stages of becoming customers, but depends heavily on the earlier stages delivering convertible prospects. Failure is not always a direct result of the current (failing) process.

Total Lead Value

The total lead value measure is an informative metric used to evaluate the overall worth or potential revenue associated with a lead or group of leads. This KPI measurement helps in the assessment of the quality and potential profitability of lead-generation efforts. 

Total lead value is calculated by assigning a monetary value to each lead based on its idealized (or moderated) potential to convert into a revenue generator. It's typically measured over a specific and agreed period to make comparisons straightforward.

Total lead value is an important KPI because it provides a clear understanding of the potential revenue impact of lead generation efforts. It serves by inducing clear prioritization of leads based on their potential value to allocate resources more precisely. Assigning values to leads can be a complex process. It often involves considering metadata such as lead source, demographic information, behavior, and historical references to evaluate the likelihood of conversion and the potential revenue that would result. It can be heavily influenced by personal methodology and must be referenced with care.

Total lead value can be segmented by: lead source, campaign, product line, or a variety of other criteria. Applying these identifies which lead-generation channels or strategies are delivering the most valuable leads to tune the application of resources in follow-on phases. Businesses use total lead value to optimize their lead generation and nurturing strategies. It should be applied to guide decisions on lead scoring, sales follow-up, and the allocation of marketing efforts. Aligning the sales team with total lead value will prioritize leads with the highest potential revenue impact. This should result in a more efficient sales process and better conversion rates when applied effectively.

ROI evaluation is closely tied to the total lead value measurement of marketing and sales efforts. It helps assess whether the cost of acquiring and nurturing leads is justified in revenue terms, and over what period. Long-term growth results from focusing on higher-value leads, enabling businesses to work toward sustainable growth and profitability. Tracking total lead value allows for a more strategic approach to lead management.

Customer Acquisition Cost

The customer acquisition cost (CAC) defines the cost a business incurs to acquire a new customer, by proportional allocation of the overall budget—rather than by actual and allocated individual budgeting. This allows assessment of the efficiency and sustainability of a company's sales and marketing efforts.

CAC is calculated by dividing the total budget/expenditure associated with acquiring all new customers (including marketing, sales, and operational expenses) by the total number of new customers acquired during the measurement period.

CAC is a key metric in that it directly reflects the financial investment required to grow a customer base. This equips businesses to evaluate the efficacy of their customer-acquisition strategies and directly defines their cost-effectiveness. The costs included in CAC calculations can vary but generally integrate marketing and advertising expenses, sales team salaries, technology and software costs, and other expenses directly allocated to the customer-acquisition continuum.

Businesses often compare their CAC to industry benchmarks or their historical performance data to assess strategy effectiveness and identify areas for underperformance. CAC is often segmented by marketing channel, campaign, or customer segment. This helps differentiate channels or strategies that are more cost-effective in the acquisition process. Reducing CAC while maintaining or increasing the quality of acquired customers is a logical goal. This results directly from optimizing marketing spend, improving conversion rates, and streamlining sales processes to reduce costs while maintaining or improving the outcomes.

The payback period can be assessed if CAC is reviewed against the customer's lifetime value. This method can be used to determine the payback period—the time it takes for the revenue generated from a customer to exceed the cost of acquisition. Efficient CAC management directly informs resource-allocation decisions, equipping businesses to allocate budgets to the most effective customer-acquisition channels or strategies.

CAC is a central plank of the assessment of the ROI of customer-acquisition efforts. It is related to payback as it also helps determine whether the cost of acquiring a customer is justified by the revenue that the customer generates.

Return on Ad Spend (ROAS)

The return on advertising spend (ROAS) is a very informative measure of the effectiveness of advertising campaigns. It works by directly relating the revenue generated to the amount spent on advertising. ROAS helps businesses evaluate the efficiency of their advertising investments and optimize their marketing strategies.

ROAS is simply calculated by dividing the revenue generated from advertising by the total advertising costs for a chosen period when the client closures for an advertising period have been deemed achieved. It is formally expressed as a ratio or percentage, such as 4:1 or 400%. ROAS is deeply informative of advertising value because it directly measures the financial impact of advertising expenditure. A higher ROAS signifies a profitable campaign and a positive ROI.

ROAS can apply to various types of advertising, including: online advertising (such as pay-per-click advertising and display ads), print media, television, radio, and social-media campaigns. Segmented evaluation that, whenever possible, relates a client closure to a point datum of advertising type in a broader campaign can be informative, although it can be difficult to pinpoint the primary contact motivator to illuminate this reliably. However, anecdotal information as to advertising element effectiveness can be used in A/B testing in broader sweep changes in ad spend. This can be an effective driver of budget allocation.

Businesses often compare their ROAS to industry benchmarks or internal historical data to assess the value proposition of their advertising campaigns. Accurate conversion tracking is essential for ROAS calculations to have any value. Businesses must define what constitutes a valuable conversion, whether it's a sale, lead, or another desired action. A loss of resolution or accuracy in the recording of the client journey through the sales funnel reduces the effectiveness of all approaches to or interpretations of ROAS.

Customer Lifetime Value

The customer lifetime value (CLV or LTV) is a long-term information source that seeks to predictively quantify the total revenue a business can expect to earn from a new customer over the entire duration of their relationship, based on the entire journey experience of “similar” past customers. It is central to a mature understanding of the long-term value of both typical and particular customers and informs strategic decisions across marketing, sales, and customer service. 

CLV is calculated by subtracting the cost of acquiring and serving a customer from the total revenue generated from that customer over their lifetime. It is typically expressed as a dollar value. CLV is fundamental because it provides deep insights into the financial impact of acquiring and retaining customers. It helps businesses prioritize customer segments, optimize marketing strategies, and allocate resources by real value rather than guesswork. Unlike many other client acquisition KPIs that focus on short-term results, CLV takes a longer-term perspective. It promotes the importance intrinsic to building lasting customer relationships and fostering customer durability.

CLV can be segmented by customer cohorts, channels, or product lines. This allows businesses to identify which customer groups or strategies are driving the highest lifetime value, and the segmentation aims to build a long-term map of the effect of changes in strategy and the optimization of processes.

CLV can be used predictively to estimate the potential value of new customers. By understanding the average CLV, or sometimes CLV differentiated by classification methods used to segment client “types”, businesses can make more informed strategic decisions about customer-acquisition spend. It is closely linked to return on investment (ROI) calculations, by determining whether the investment in acquiring and retaining (particular, typically generalized) customers is justified by the revenue they generate over time. It tends to drive businesses to adopt a more customer-centric approach, highlighting the revenue benefits of prioritizing customer satisfaction and building strong, lasting relationships.
