Marketing vs. Sales Leads: Solve the Lead Quality Debate

In B2B marketing, lead generation remains a critical driver of business growth. Yet, somewhere along the way, the definition of a lead—specifically a Marketing Qualified Lead (MQL) and a Sales Qualified Lead (SQL)—has become muddled. Sales teams today often treat an SQL as though it should immediately convert into a sale, and if it doesn’t, the lead is deemed low-quality. This shift in expectations has created a damaging misalignment between Marketing and Sales teams.

Instead of viewing leads as potential relationships to be nurtured, many organizations expect them to close immediately. This unrealistic standard not only undermines marketing efforts but also hinders the long-term success of Sales teams.

At its core, this issue stems from three fundamental problems:

1. A Lack of Standardized Definitions

• In many organizations, there is no universally agreed-upon definition of an MQL, an SQL, or even a “sale.”
• Marketing and Sales teams operate under different assumptions, leading to frustration, inefficiencies, and missed revenue opportunities.
• Worse, some team members may actually prefer this ambiguity because it allows them to shift accountability.

2. The Misconception That Lead Quality = Immediate Conversion

• A lead’s quality should not be judged solely by how quickly it converts into a deal.
• A well-qualified lead still requires nurturing—sales professionals must build relationships, understand customer needs, and present solutions before closing a deal.
• Expecting leads to close immediately ignores the complexities of the B2B buying cycle, which can take weeks or even months.

3. The Marketing-to-Sales Black Hole

One of the biggest failures in most B2B organizations? Marketing has no visibility into whether their leads convert.

• Marketing operates on one set of tools (marketing automation platforms, demand-gen systems).
• Sales operates on another (CRM, sales enablement platforms).
• These systems rarely talk to each other.

For all the money businesses spend on CRM and data management, it’s shocking that Marketing teams often don’t know which leads actually turned into revenue. Without feedback, Marketing keeps optimizing for lead quantity, not quality—and the cycle repeats.

But Marketing Isn’t Off the Hook, Either
While Sales teams need to take accountability for nurturing and closing leads, this doesn’t mean Marketing shouldn’t be held accountable for lead quality. Too often, Marketing teams are incentivized based solely on the volume of leads rather than their quality. When lead generation is treated as a numbers game, media plans are often designed to drive as many leads as possible—regardless of whether those leads have a strong likelihood of converting.

So, how do we fix this? The key is to start with the attributes of your best customers:

• Who are they?
• What are their attitudes, values, and behaviors?
• Where did they come from?
• How did they first engage with your company?

By defining these characteristics, companies can establish clear criteria for what makes a good lead, which can then be incorporated into lead scoring systems within most CRM platforms. This ensures that Marketing is measured not just on how many leads they generate but also on how qualified those leads are.

Fixing the Marketing vs. Sales Lead War

If companies want to stop the lead blame game, they need to take six critical steps:

1. Define What MQL, SQL, and Sales Actually Mean

• Sales and Marketing must align on a single definition of an MQL and SQL.
• Everyone should know when and how a lead transitions between teams.
• Lead status should be tracked and visible in real-time.

2. Stop Measuring Lead Quality by Immediate Conversion

• Leads should be evaluated on their fit, engagement, and long-term potential, not just how fast they close.
• Sales needs to stop blaming Marketing for leads that require nurturing.
• Instead of rejecting leads outright, Sales teams should provide feedback on why certain leads don’t convert.

3. Hold Marketing Accountable for Lead Quality (But the Right Way)

Yes, Marketing should be responsible for lead quality—but not just by reducing lead volume. The best way to ensure lead quality is to analyze existing high-value customers and build lead criteria based on:

• Their attributes, behaviors, and engagement patterns.
• The channels they came from.
• The messaging that resonated with them.

This data should then inform lead scoring models to ensure Marketing isn’t just generating more leads, but better leads.

4. Remember That Brand Matters in Lead Generation

Brand-building directly impacts lead generation efficiency. Studies show that well-known brands experience lower cost per lead (CPL) and stronger engagement. The reason? When prospects already recognize and trust your brand, they are more likely to interact with Marketing and Sales efforts. (See the recent WARC Study here: The Multiplier Effect Report).
 

Additionally, many early interactions happen in the “dark funnel”—stages of the buyer’s journey that aren’t directly trackable, such as:

• Peer recommendations.
• Organic content consumption.
• Brand awareness and thought leadership exposure.

Marketing teams must not overlook branding just because it doesn’t fit neatly into performance marketing dashboards. Investing in brand awareness and trust-building activities helps make lead generation more efficient and improves conversion rates over time.

5. Integrate Marketing and Sales Tech Stacks

• Ensure that CRM systems and marketing platforms are connected.
• Enable real-time tracking of conversions and lead quality to allow Marketing to refine lead generation strategies.
• If Marketing doesn’t know which leads are converting, they can’t improve.

6. Create a Feedback Loop Between Marketing and Sales

• Sales must provide structured feedback on why leads are converting or not.
• Marketing should have access to conversion and pipeline data to adjust targeting and messaging.
• Without this feedback loop, both teams will continue pointing fingers instead of optimizing the process.

Conclusion

B2B lead generation isn’t failing because Marketing generates bad leads or because Sales won’t close them. It’s failing because Marketing and Sales are operating in silos, with different expectations and no shared accountability.

If we want to fix this, we must:

• Clearly define what MQLs, SQLs, and sales mean.
• Shift the focus from immediate conversion to long-term relationship-building.
• Hold both Marketing and Sales accountable.
• Bridge the gap between marketing and sales tech stacks.
• Recognize that brand awareness fuels lead generation.

When Sales and Marketing stop fighting over lead quality and start collaborating, businesses will close more deals and drive more revenue.
