Data is everything, especially in the B2B digital marketing space. Marketers are constantly searching for ways to optimize their campaigns, improve lead conversion rates, and make more informed decisions. That’s where B2B marketing analytics comes in.

Effective marketing analytics allows businesses to track key performance indicators (KPIs), understand the behavior of leads, and determine which strategies drive the most value. But it’s not just about collecting the data; it’s about understanding it. One of the most important aspects of B2B marketing analytics is lead tracking and attribution–the ability to monitor how leads interact with your brand and ultimately attribute those interactions to conversions.

This post will take you through the basics of marketing analytics to help you better understand the importance of data in your marketing strategies.

What is B2B Marketing Analytics?

B2B marketing analytics is the practice of using data to evaluate, measure, and optimize marketing efforts in a business-to-business context. It involves collecting and analyzing data from various marketing channels and activities to better understand the effectiveness of campaigns, track customer behaviors, and make more informed decisions that improve ROI.

Unlike B2C marketing, which often focuses on a broader audience, B2B marketing analytics deals with a more targeted approach. This data helps B2B marketers measure how well they’re reaching specific business clients, understanding their pain points and needs, and nurturing them through the sales funnel.

For example, in the manufacturing industry, a company might track how potential clients–such as distributors or wholesalers–engage with their content. If a manufacturer is running a campaign for new machinery, B2B marketing analytics can show how many leads are coming from specific industries (e.g., automotive or food production), which pieces of content they’re interacting with, and how long they stay on key pages.

At the heart of B2B marketing analytics are metrics that provide insights into key performance indicators (KPIs) like:

  • Lead Generation: Tracking how many leads are being generated and where they come from. I would recommend you have a good understanding of how and when your MQLs (Marketing Qualified Leads) turn into SQLs (Sales Qualified Leads).

  • Closed Won Deals: Understanding how many leads turn into paying clients.

  • Customer Lifetime Value (CLV): Measuring the total revenue generated by a client over the course of your relationship.

While this all may sound simple to track, it might not be depending on your analytics tracking that is in place. One of the significant challenges that many B2B businesses face is a long sales cycle, often lasting several months or even over a year. This extended timeline can make it difficult to accurately track conversion touchpoints. That’s why it’s important to have a closed-loop analytics reporting solution in place, one that bridges the gap between your marketing and website platforms, such as LinkedIn, Google Ads, or Google Analytics 4, and your CRM system, such as Salesforce or HubSpot.

With these marketing insights and alignment between your marketing and sales teams, B2B marketers can optimize marketing strategies, identify effective marketing channels, and better allocate resources and budget.

The Importance of Tracking and Attributing Leads

Tracking and attributing leads is important for understanding which marketing efforts are truly driving your business growth. Without proper tracking in place, it’s difficult to know which campaigns, channels, or touchpoints are influencing the decision-making process of your leads.

Lead attribution goes beyond simply tracking the source of a lead; it involves assigning credit to different touchpoints that a lead encounters along their journey. Whether they came from an ad on LinkedIn, a referral from a partner, or a downloadable resource on your website, understanding these interactions allows you to make more informed decisions about where to allocate resources and how to optimize future campaigns.

By implementing effective lead tracking and attribution, you can:

  • Understand the full journey: Tracking each touchpoint along the lead’s journey provides valuable insights into the most effective channels and strategies. It helps you identify which activities are truly moving the needle.

  • Optimize marketing spend: When you know which channels are most effective, you can shift your marketing budget toward the high-performing ones. If you discover that a significant number of conversions are coming from organic search rather than paid media ads, you can adjust your investment and resources toward the working channel.

  • Measure campaign success: Lead attribution gives you a clearer picture of how well your campaigns are performing. Whether it’s a paid search campaign or a sponsored event, you’ll have data to back up your decisions, showing which initiatives deliver the best results.

  • Refine your strategy: Attribution insights help refine your marketing strategy over time. You can focus more on the tactics that produce high-quality leads and reduce efforts on underperforming activities. It also ensures that your marketing efforts are aligned with your sales team’s goals, driving higher conversion rates.

It’s important to note that many marketing and CRM tools have their own attribution models built into the platform themselves. Understanding how each tool attributes leads is important to get a clear view into the customer journey and managing that data effectively.

I know that managing attribution models across platforms can be tricky, especially when different tools have different ways of assigning credit to various touchpoints. To get the most accurate and comprehensive data, it’s important to integrate your systems and create a unified view of your lead’s journey. This can be done through a closed-loop analytics solution that ties marketing data from tools like Google Ads and Salesforce together.

Without proper tracking and attribution, you could be left not knowing how well (or poorly) your campaigns are performing. By fully understanding how leads move through your sales funnel and how different platforms attribute their journeys, you can improve your marketing tactics, better align with your sales team, and ultimately drive more qualified leads and revenue.

Types of Lead Attribution Models

Lead attribution models are important for understanding how touchpoints contribute to the conversion process. These models help assign credit to different interactions that a lead has with your business across multiple channels. The right attribution model can provide insights into which efforts drive the most valuable leads and ultimately impact your revenue.

There are several common lead attribution models used in B2B marketing, each with its own strengths and weaknesses. Below, I’ll highlight some popular models and how they work:

  1. First-Touch Attribution

    First-touch attribution assigns 100% of the credit to the first interaction a lead has with your brand, whether that’s a website visit, an ad click, or a content download. This model is useful for understanding which channels or touchpoints are most effective at generating initial awareness and attracting new leads.

    • When to use it: This model is ideal when you want to understand which channels are driving initial interest. For instance, if you’re running a brand awareness campaign and need to assess which sources are bringing in the first wave of traffic, this model can help you evaluate that.
      • Pros: Simplifies the process of understanding where leads are coming from at the very beginning of their journey.
      • Cons: It ignores all the subsequent interactions that a lead might have with your brand, making it difficult to see the full picture of their journey.

  2. Last-Touch Attribution

    Last-touch attribution gives all the credit to the final interaction before a lead converts. This model is popular because it places emphasis on the closing touchpoint, such as a final demo or product purchase decision.

    • When to use it: This model is beneficial for evaluating the effectiveness of your closing activities or if you’re focused on understanding what’s sealing the deal. For instance, if you’re running remarketing campaigns aimed at converting leads, this model helps track which ads or emails lead directly to conversions.
      • Pros: Easy to implement and useful for measuring final touchpoints and conversions.
      • Cons: Like first-touch, last-touch attribution neglects the other touchpoints in the lead’s journey, which may play a significant role in nurturing them toward a final decision.

  3. Linear Attribution

    Linear attribution assigns equal credit to all touchpoints in the customer journey. Each interaction, whether it’s an ad click, an email open, or a website visit, is given the same amount of weight. This model provides a more balanced view of how different marketing activities contribute to a conversion.

    • When to use it: This model works well if you want to acknowledge the importance of all touchpoints in the customer journey, especially in a long B2B sales cycle where multiple touchpoints may be involved before conversion.
      • Pros: Provides a fair distribution of credit across all touchpoints, offering a more holistic view of the journey.
      • Cons: It might now give enough weight to the most impactful touchpoints or channels that played a pivotal role in driving the conversion.

  4. Time-Decay Attribution

    Time-decay attribution gives more credit to touchpoints that occur closer to the conversion event. The model operates under the assumption that the closer an interaction is to the final decision, the more influence it has. This model is ideal for understanding the impact of nurturing leads over time.

    • When to Use It: This model is particularly useful in B2B marketing where leads may take months to convert and interact with several marketing assets over that period. It helps prioritize recent touchpoints, like a demo or final sales call, over early-stage interactions.
      • Pros: Reflects the true influence of later-stage interactions in long sales cycles, offering insights into the final push that converted the lead.
      • Cons: It doesn’t give enough credit to early touchpoints, which may have helped build awareness or interest.

  5. Multi-Touch Attribution

    Mult-touch attribution combines elements of the previous models to give credit to multiple touchpoints across the customer journey. Depending on how the model is configured, it can assign varying weights to each touchpoint, offering a stronger understanding of how each stage of the journey contributes to the final conversion.

    • When to use it: Multi-touch attribution is best used when you want to gain a comprehensive view of your marketing funnel and measure the effectiveness of all touchpoints. It’s useful for complex B2B sales cycles where multiple marketing efforts work together to close a deal.
      • Pros: Provides a well-rounded perspective by considering multiple interactions across the journey, allowing for more accurate insights and stronger optimization.
      • Cons: It’s complex to implement and requires robust data integration across systems.

  6. Data-Driven Attribution

    Data-driven attribution (DDA) uses machine learning and historical data to assign credit to various touchpoints along the lead’s journey based on their actual impact on conversion. Rather than relying on predefined rules, this model adapts to your specific data to provide an accurate picture of how each interaction contributes to conversions. It evaluates patterns in the data and dynamically allocates credit to touchpoints based on their influence, giving marketers a more precise view of the customer journey. However, while this is my preferred model, it’s important to note that if your conversion action does not have enough data, data-driven attribution might not be possible for you!

    • When to use it: This model is ideal for B2B businesses with complex, long sales cycles, where multiple touchpoints are involved across different channels. Data-driven attribution works well for companies that want to optimize their marketing strategies based on real insights rather than assumptions or static rules.
      • Pros: Provides an accurate, data-backed picture of the customer journey, and continuously learns and adapts based on new data, improving accuracy over time.
      • Cons: Requires sufficient historical data to work effectively and can be complex to implement.

Each attribution model (and these aren’t all of them!) serves a specific purpose, and choosing the right one depends on your marketing goals and the length of your sales cycle. In B2B marketing, multi-touch or data-driven attribution might be the most appropriate option, especially when dealing with longer sales cycles and multiple points.

By selecting the right model and understanding the data, B2B marketers can better understand which marketing activities are driving real value.

Metrics to Track in B2B Marketing Analytics

To make the most of your B2B marketing analytics, it’s important to focus on the right metrics that provide actionable insights into your marketing efforts. Tracking the right metrics helps to understand how your campaigns are performing and also guides you in optimizing strategies for better results.

Below are some of the metrics that I recommend tracking for a B2B business:

  1. Website Traffic:

    This may be an obvious one, but it’s important to get people to your website in the first place! This metric refers to the number of visitors coming to your website and helps assess the reach and effectiveness of your digital marketing campaigns, such as SEO, paid ads, and content marketing.

  2. Conversion Rate (CVR):

    The conversion rate measures how many of your website visitors or leads take the desired action, whether it’s filling out a form, downloading a resource, or requesting a demo. High conversion rates indicate that your landing pages, calls to action (CTAs), and content are effectively engaging visitors.

  3. Marketing Qualified Leads (MQL):

    Leads that have engaged with your content and shown interest in your product or service, but are not yet ready for sales outreach. MQLs are the leads that marketing deems worthy of being passed on to the sales team for further nurturing.

  4. Lead Conversion Rate:

    Lead conversion rate tracks how many leads turn into paying customers or sales-qualified leads (SQLs). This metric helps you assess the effectiveness of your sales funnel and the ability of your sales team to convert leads into customers.

  5. Customer Acquisition Cost (CAC):

    CAC calculates the total cost to acquire a new customer, including marketing expenses, sales efforts, and other related costs. This metric helps you to understand the efficiency of your marketing and sales process.

  6. Customer Lifetime Value (CLV):

    This metric measures the total revenue a customer is expected to generate during their relationship with your business. Understanding CLV helps you determine how much you should invest in acquiring and retaining customers.

  7. Cost Per Lead (CPL):

    CPL measures how much you are spending to acquire a lead through your marketing efforts. It’s important to determine the effectiveness of your campaigns in generating leads at an affordable cost.

  8. Monthly Recurring Revenue (MRR):

    MRR measures the predictable revenue you generate every month from your products or services. MRR provides a clear view of your business’s financial health and growth.

  9. Churn Rate:

    The churn rate measures the percentage of customers who stop using your product or service over a given period of time. This is an important metric for businesses to track because a high churn rate can negatively affect revenue growth.

  10. Return on Investment (ROI):

    This metric measures the return you’re getting from your marketing investments. It’s calculated by dividing the revenue generated by your marketing activities by the total cost of those activities.

  11. Revenue:

    You can’t get ROI without tracking your revenue! This is the total income generated from sales of business activities. For B2B businesses, tracking revenue is the ultimate goal of your marketing and sales efforts, as it directly ties back to business growth and profitability.

Best Practices for Tracking and Attributing B2B Leads

Effective lead tracking and attribution are key to improving your marketing strategies and optimizing for ROI. However, without proper practices and tools in place, it can be difficult to get a clear picture of how your leads are progressing through the funnel. Implementing best practices ensures that your efforts are data-driven and provide the insights you need to make more informed decisions. Below are some best practices to follow:

  1. Implement Closed-Loop Analytics

    Closed-loop analytics bridges the gap between your marketing and sales efforts by connecting the data from your marketing platforms (Google Ads, LinkedIn, etc.) with your CRM system (like Salesforce or Hubspot). This approach allows you to track the entire customer journey, from the first interaction to the final sale. Might I add, that this is probably the most important thing to get set up in B2B marketing.


    How to implement: Ensure that your CRM and marketing platforms are integrated to share data. For example, set up UTM parameters to track sources, and ensure that all leads are captured in your CRM. You can also connect your CRM to platforms like Google Ads so the marketing platform can optimize toward conversions that really matter. Additionally, make sure that all sources are tied together in a single source of truth in some sort of marketing dashboard such as Looker Studio or Tableau. Lastly, make sure that both the sales and marketing teams have access to that dashboard so both teams remain on the same page!

  2. Use Call Tracking

    For B2B businesses, especially those with complex sales processes or those offering high-ticket items, call tracking can be an invaluable tool. Call tracking helps you tie phone calls to specific marketing campaigns, channels, and touchpoints. This is important because phone interactions are very prevalent in converting B2B leads.


    How to implement: Use call tracking tools like CallRail to assign unique phone numbers to different campaigns, landing pages, and channels. This will allow you to trace incoming calls back to specific marketing efforts. Bonus: CallRail offers a product called “Conversation Intelligence”, which analyzes your calls and turns them into instant insights. Knowing the conversations your sales teams are having is a great way to generate new content, pivot your UVPs, or revise your marketing strategies.


  3. Set up Proper Tracking Parameters

    Accurate tracking starts with setting up the right tracking parameters across all your digital assets. Use UTM codes for campaigns, emails, and ads to track where your traffic is coming from and how it’s engaging with your content. It’s also important that if there are multiple marketers on your team, everyone on the team knows how to tag different campaigns as new campaigns launch over time and across channels. I recommend building a master “key” that houses all the sources, campaign names, etc. in one sheet for easier access.


    How to implement: Create custom UTM codes for each campaign and ensure they are applied to all your outbound links (ads, emails, social media). There are free tools out there that can help facilitate the creation of UTMs if needed!


  4. Align Marketing and Sales Teams

    Arguably, this is one of the harder things to do at many B2B businesses, especially at a more enterprise level. However, a strong alignment between marketing and sales is critical for successful lead tracking and attribution. The marketing team should be responsible for generating leads and nurturing them, while the sales team focuses on converting those leads into paying customers. The two teams need to share insights, track progress, and collaborate on strategies.


    How to implement: Establish clear definitions for the lead flow and identify when a lead moves throughout the lead journey. Regularly meet to review the quality of leads, discuss attribution data, and ensure both teams are aligned on goals and metrics.


  5. Use Multi-Channel Attribution Models

    In B2B marketing, customer journeys are not linear. Leads often interact with your brand across multiple channels before converting. To accurately measure the impact of each touchpoint, it’s important to use multi-channel attribution models that give credit to each interaction along the way.


    How to implement: Use attribution models like data-driven (DDA) or multi-touch attribution to analyze how multiple channels contribute to conversions. This can include email, paid search, content marketing, social media, and more. Ensure your tools are properly integrated to capture interactions across all platforms.


  6. Monitor and Optimize Lead Quality

    Tracking leads is important, but it’s equally important to monitor and optimize lead quality. Keep an eye on how your MQLs are converting into SQLs and paying customers. Not all leads are created equal, and focusing on high-quality leads will yield better results in the long run.


    How to implement: Use tools like lead scoring, which helps you rank leads based on their engagement and likelihood of conversion. Continuously evaluate the lead scoring criteria to ensure that you’re focusing on the best opportunities.


  7. Regularly Analyze and Adjust

    Tracking and attribution aren’t one-time tasks; they require ongoing analysis and adjustments. Regularly reviewing your data helps you stay on top of what’s working and what isn’t.


    How to implement: Set up monthly or quarterly reviews of your marketing data. Use dashboards and reports to track metrics like CVR, CAC, CLV, and ROI. Based on the results, adjust your marketing spend, messaging, and lead-generation tactics.

By following these best practices. B2B marketers can ensure they’re effectively tracking and attributing leads to the right campaigns and channels. This not only improves the quality of your leads but also provides stronger insights into marketing performance, allowing for better marketing results.

Optimizing Your B2B Marketing Strategy

The importance of data-driven decision-making cannot be overstated in B2B marketing. By leveraging the right analytics tools and adopting a strategic approach to lead tracking and attribution, you can gain stronger insights into your marketing efforts.

To ensure long-term success, it’s important to review, analyze, and optimize your strategy based on what the data is telling you. With the right practices in place, your B2B marketing will be positioned for sustained growth, more qualified leads, and improved ROI.
