Do you need to generate leads through a channel that turns anonymous visitors and current leads into a known pipeline? In that case, hosting a webinar has probably crossed your mind.

And it's for good reason. Webinars have been a go-to strategy for teams looking to get that done. 

Research shows that 73% of B2B marketing and sales leaders agree. 

But teams still struggle with the following scenario:

Marketing just wrapped up another webinar. Fifty attendees joined. The engagement looked solid. You identified pain points from the Q&A session. Three leads downloaded your white paper afterward.

But when and if an attendee becomes a customer, how much credit should that webinar receive?

Most marketers don't have the answer. They're flying blind when it comes to webinar attribution.

The Webinar Attribution Challenge for B2B Marketers

‍Data shows that 64% of B2B marketers hosted webinars, virtual events, or online courses in the past year. The medium is a mainstay in marketing strategies for good reason : webinars offer teams a high-intention, cost-effective channel that engages leads further down in the funnel. The average cost per lead is just $72, compared to trade shows, which exceed $800 per lead.

Even with the impressive numbers, marketers struggle to prove webinar ROI beyond basic attendance metrics. 

The problem isn't your webinar content. Not your promotion strategy, either. The issue lies in how you measure success after people leave.

Attribution models treat webinars like one-off touchpoints. A lead attends, watches the recap, and all subsequent tracking goes unseen. 

But buying journeys don't work that way. Prospects continue engaging with your content across channels, weeks or months after watching your webinar.

If your attendees find value in your solution after the webinar, they will visit pricing pages. They may also download case studies, click LinkedIn ads, and, hopefully, schedule demos. 

When they finally become a paying customer, which touchpoint deserves credit?

Without the right multitouch attribution model, you're missing the complete picture of your webinar's influence on revenue.

Calculating the True Cost of B2B Webinars in 2025

Uncovering webinar ROI begins with understanding your actual costs. Most teams underestimate the total cost.

Subscriptions to webinar software are just the tip of the iceberg. Production typically costs between $3,000 and $5,000 per event. This includes content creation, registration pages, webinar promotion, technical setup, and follow-up campaigns to keep attendees engaged.

Consider a company that hosts 20 webinars a year. Platform costs alone could reach $7,200 yearly. Add production costs, and you're looking at over $100,000 in annual webinar investment.

For teams that outsource production and logistics, full-service event management costs between $500 and $1,500 per webinar. This is for companies that lack internal resources. This adds another layer of cost that marketing needs to cover with the revenue generated from webinars.

If ROI is the goal, these numbers matter. Accurate ROI calculation requires comprehensive cost tracking, and you can't measure success without knowing your actual investment.

Measuring Webinar ROI in Salesforce

Along with pinpointing costs, considering how your webinar platform of choice integrates with Salesforce is integral before making a choice.

If you want to ensure your webinar platform is sending reliable data to Salesforce, you need to make sure it offers the following features:

• Campaign creation in Salesforce when a new webinar is created
• Customizable Campaign Member status' to keep tabs on leads, such as registered, attended, or no-show, for example
• Creation of new leads and contacts in Salesforce if they don't exist
• Automatic updates of Campaign member status based on attendance

With the following features, you'll be able to leave the manual tracking to your webinar solution and Salesforce while avoiding human error.

Avoiding Common Measurement Mistakes

Let’s say you've found the right webinar solution with a Salesforce integration that sends the information you need to track attendees automatically. Looks like smooth sailing from here on out. 

That may be the case, but in most cases, you're tracking vanity metrics like webinar engagement scores and attendance.

While attendee numbers and webinar engagement scores appear impressive on paper, these vanity metrics won't drive meaningful results.

Rather than sharing vanity metrics, tying attendance to a new or existing Opportunity in Salesforce helps marketing provide sales and RevOps with the visibility they need.

Despite the manual process, this step enables marketers to demonstrate their ability to move different buyer personas down the funnel.

Going a step further and classifying each attendee by their phase in the funnel and buyer persona will allow you to see the influence webinars have on:

• Net New leads generated
• Existing Leads
• Re-engaged prospects, such as unconverted leads or existing contacts from accounts without an open opportunity
• Existing contacts from accounts with open opportunities

With this classified lead information, you'll also be able to target attendees with the right messaging to engage potential buyers.

Whether they are new clients, cross-sell opportunities, or lost clients with new interests, you'll be able to pinpoint pipeline and revenue potential rather than highlight vanity metrics.

Attribution Blind Spots in Salesforce

Herein also lies an issue with Salesforce; its native attribution models aren't designed for complex buying journeys that webinar attendees embark on.

Unless you're working with a highly customized attribution solution that has taken months to implement in Salesforce, here's where the native solutions fall short:

Lead Source Limitations

Teams using the basic Lead Source field lack campaign-level granularity. While you may have "Webinar" as a source, it doesn't indicate which webinar influenced the conversion or what path a prospect took after attending.

Primary Campaign Source Problems

Salesforce's Primary Campaign Source uses last-touch attribution. If a lead attends your webinar next week but converts through a Google ad a month later, the webinar receives zero credit. This method doesn't give the due it deserves to other channels your prospects engage with before and after the webinar.

Campaign Influence Complexity

Custom Campaign Influence provides multitouch attribution, but it requires manual setup and constant maintenance. You need consistent Contact Roles, Campaign Member status updates, and complex automation flows. Most teams lack the resources for proper implementation.

Mapping the Complete B2B Webinar Participant Journey

Effective webinar attribution requires understanding the whole journey across every touchpoint, which means tracking:

Pre-Webinar Engagement

In most cases, your attendees didn’t engage with the first communication promoting your webinar. They may have seen a LinkedIn ad, received an email invitation, visited a landing page, or clicked a banner in a blog post. Every touchpoint influences their decision to register.

During-Webinar Interaction

Engagement scores show participation levels, poll responses, and live chat activity. However, this data rarely flows into Salesforce, resulting in a loss of valuable insights that could have made they're way into sales copy and personalized emails responding to buyer questions.

Post-Webinar Behavior

Following the webinar, your attendees are highly engaged and are evaluating your brand across various channels:

• Visiting product pages multiple times
• Downloading additional resources
• Engaging with nurture email sequences
• Clicking retargeting advertisements
• Attending follow-up demos or sales calls

Without the cookieless tracking technology, you’re not identifying these key interactions happening before and after your webinars. 

But with the right tech, webinars can be more than lead magnets and finally receive the credit for accelerating sales cycles and driving revenue.

Complete Webinar Attribution: Tracking Webinar ROI with Heeet

Webinar platforms offer detailed metrics on webinar engagement, including attendance duration, interaction rates, and participant behavior.

However, these platforms focus solely on the webinar experience itself.

Heeet helps marketers extend lead visibility after webinar attendance using cookieless tracking.

The solution ensures seamless data flows between webinar engagement metrics, ongoing prospect behavior, and Salesforce revenue attribution.

How Heeet Works

Webinar registration data flows from your webinar platform into Salesforce. Heeet then tracks every subsequent interaction across your channels without relying on third-party cookies. This includes:

• Website visits and page views
• Content downloads and engagement
• Advertisement interactions across platforms

All tracking happens while maintaining privacy compliance and keeping prospect data secure within your Salesforce environment.

Moving Past Traditional Attribution Models

While most solutions offer first-touch or last-touch attribution, Heeet provides multitouch visibility that reflects real buying behavior. You can see how webinar participation influences prospects across weeks or months of additional touchpoints.

The cookieless approach future-proofs your attribution strategy against ongoing changes in privacy regulations. More importantly, you maintain complete visibility regardless of browser settings.

Key Metrics That Go Beyond Attendance

Traditional webinar metrics focus on participation rates and engagement scores. Complete attribution tracking adds revenue-focused measurements:

• Net new pipeline vs. engaged/activated pipeline
• Pipeline influence across multiple opportunities
• Revenue attribution by webinar topic or format
• Customer lifetime value by initial webinar attendance
• Time-to-close acceleration for webinar participants

Complete webinar attribution reveals which topics drive revenue, which formats accelerate deals, and which follow-up sequences convert best. 

These metrics transform webinars from lead-generation activities into measurable revenue drivers with clear business impact.
