21 Salespeople Reveal the Worst Sales Advice They Ever Received

Sales is a field where advice, tips, and "best practices" are constantly circulating. As salespeople, it can be hard to know which nuggets of wisdom to take to heart and which to ignore.

Unfortunately, a lot of the conventional sales advice out there is misguided at best and downright detrimental at worst. In fact, a recent survey found that 62% of B2B salespeople have received sales coaching that actually made them worse at their job. And 72% of sales managers themselves admit to having followed bad sales advice at some point in their career.

Blindly following the wrong sales tips can have serious consequences – from wasting precious time to eroding trust with customers to missing quota. That‘s why it‘s so critical for modern sellers to think carefully about which tactics will truly move the needle.

To help separate the good advice from the bad, we asked 21 experienced sales professionals to share the worst suggestions they‘ve heard over the course of their careers. Here‘s what they had to say.

1. "It‘s all a numbers game – focus on your activity metrics"

One of the most persistent pieces of sales advice is to measure success based on the number of calls made, emails sent, or meetings booked. Many old-school sales managers heavily emphasize hitting arbitrary activity quotas over tracking the actual results generated.

"I once worked for a manager who put a great deal of emphasis on activity metrics rather than sales outcomes," recalls Mary Burbridge, Senior Inbound Growth Specialist at HubSpot. "I was advised to send 1,000+ generic emails per day to a list of contacts across various industries. Not only did this hurt my credibility as a salesperson and my company‘s reputation, but it ingrained prospecting habits that are ultimately unsuccessful in the long term."

Research has consistently shown that quality matters far more than quantity when it comes to sales outreach. One study found that highly personalized emails generate 18 times more revenue than generic batch-and-blast emails. And SAP reported that their "quality over quantity" approach to sales calls allowed them to reduce call volume by 26% while increasing revenue by 28%.

Takeaway: Don‘t just go through the motions to check activity boxes. Focus your time on reaching out to carefully targeted, high-value accounts with relevant, customized messaging. Track meaningful outcome metrics, not vanity activity metrics.

2. "Cast a wide net – try to sell to anyone with a pulse"

Another common piece of misguided sales advice is to pursue as many leads as possible rather than narrowly targeting ideal customers. Traditional selling lore says that more prospects equals more sales opportunities.

However, in the age of empowered buyers, indiscriminately chasing poor-fit prospects is more likely to waste everyone‘s time than drive results. Only 3% of buyers trust sales reps, in large part because of bad experiences with reps trying to force their product on them.

"While this ‘sell to everyone‘ advice may have worked in the past, modern salespeople need to focus on engaging good-fit customers," says Dan Tyre, Sales Director at HubSpot. "Today‘s most effective reps deeply understand their target niche and make sure they‘re starting real relationships with people who have the need, budget, and authority to buy – and will actually get value from the product."

A study by MarketingSherpa found that leads who are a strong demographic and psychographic fit are 8 times more likely to become customers. Contrast that with research showing 50% of prospects are a poor fit for what‘s being sold to them. Focusing on quality over quantity and disqualifying bad fits early is key to a productive pipeline.

Takeaway: Develop a clear ideal customer profile and focus your prospecting efforts there. Thoroughly qualify leads early in the sales process to ensure there‘s a mutual fit before investing more time. Chasing anyone with a pulse is an outdated tactic.

3. "Never take no for an answer"

Persistence is an important quality in sales, but there‘s a fine line between respectful follow-up and becoming a stalker. A lot of old sales methodologies glorify the "bulldog" approach of being relentlessly persistent, even in the face of clear rejection.

Tyson Hartnett, Sales Development Rep at LiveIntent, once received this cringeworthy coaching: "I‘d given a 45-minute pitch, we‘d negotiated for 15 minutes, and then the prospect definitively said no and got off the phone. My manager said, ‘Call them back immediately.‘"

But in an era where buyers have more power, choice and access to information than ever before, endlessly hounding prospects who aren‘t interested won‘t get you anywhere. A LinkedIn survey revealed that 50% of buyers don‘t want to interact with sales reps at all during the awareness stage of their buying journey. There‘s a time and a place for follow up, but refusing to take no for an answer is more likely to earn you a restraining order than a customer.

Respecting a prospect‘s preferences and boundaries is not only the right thing to do – it‘s good business. Pressuring someone into a sale they don‘t want only breeds resentment and negative word of mouth. And even if you manage to momentarily wear them down, they‘re highly likely to churn later. Accepting a firm "no" preserves your time, reputation and future selling chances.

Takeaway: Tailor your persistence to the buyer‘s cues. Set the right expectations for your follow up and deliver value each time, but know when to respectfully move on if they make it clear they aren‘t interested. Pushy tactics are a thing of the past.

4. "Demo first, ask questions later"

Speed is often touted as a sales virtue, so reps may feel pressured to move deals along as quickly as possible by jumping straight into a generic product demo. Discovery conversations can seem less productive than pitching.

However, demos are only effective if they‘re highly relevant to that specific buyer‘s needs and situation. Without doing proper discovery and qualification first, it‘s impossible to know which features, use cases and value points to highlight.

"Any time I try to combine discovery and demo calls to save time, I end up missing critical information about the prospect‘s goals, plans, and challenges that I need to close the deal," says Caroline Ostrander, Inbound Growth Specialist at HubSpot.

According to Gong.io, top performing sales reps spend 57% more time on discovery than their peers. SiriusDecisions found that the highest performing B2B sales teams (those with 75%+ quota attainment) are twice as likely to believe lead nurturing is the responsibility of both sales and marketing, compared to underperforming teams.

Thoroughly understanding the buyer‘s needs and situation is a prerequisite for delivering a compelling sales presentation. Even if it feels inefficient, don‘t be tempted to shortcut the discovery process.

Takeaway: Slow down and take the time to ask probing questions before pitching your solution. Tailor your demo to the prospect‘s specific use case and objectives. Rushing to present without context is a recipe for stalled deals.

5. "ABC – Always Be Closing!"

Perhaps the most famous piece of sales advice is the "always be closing" (ABC) mantra from the movie Glengarry Glen Ross. It reflects an old-school mentality that a good salesperson is essentially a silver-tongued "closer" who can convince people to buy through persuasion and force of personality.

"I‘ve encountered colleagues who implied that you‘ll be the most successful rep if you‘re a ‘closing machine‘ who is constantly pushing prospects to sign," says Caitriona O‘Flaherty, Channel Account Executive at HubSpot. "But I‘ve found that the best salespeople are laser-focused on helping the customer first and foremost. Pressuring everyone to buy quickly has the opposite effect."

The stats bear this out – a LinkedIn survey found that the top sales priority for 65% of sales managers is "improving the sales funnel" through careful qualification, not aggressive closing. According to SiriusDecisions, high-performing reps are 32% more likely than other reps to excel at lead nurturing.

At the end of the day, buyers don‘t want to feel like they‘re being strong-armed into a purchase by a smooth-talking "closer." They want to feel educated and empowered to make the right decision for their business needs.

Serving as a helpful consultant, not a pressuring salesperson, is what builds trust in the modern buying landscape. Guide buyers to their own conclusion that your solution is the best fit, and the close will come about organically.

Takeaway: Retire the "always be closing" cliché. Focus on always being helpful, responsive, and insightful. Deliver value at every interaction and the sale will take care of itself when the time is right.

The Bottom Line

The sales profession has evolved dramatically in recent years as buyer behaviors and expectations have shifted. Many once-popular sales tropes and tactics have become ineffective at best and damaging at worst.

But with so many self-proclaimed sales gurus and old-school sales leaders out there, misguided advice still abounds. Knowing how to separate the good from the bad is a critical skill for advancing your career and driving consistent sales success.

As a rule of thumb, be wary of any tactic that views selling as a "numbers game" to be won through brute force and smooth talking. In the modern sales environment, the most effective reps lead with a genuine desire to help their customers succeed. They focus on efficiently providing value to the right prospects, not maximizing their raw activity.

So the next time you hear a piece of sales advice, take a moment to critically evaluate it. Consider whether it‘s truly in the best interest of your buyer. If it seems rooted in an adversarial or self-serving mentality, chances are it‘s a piece of "wisdom" better left in the past.

Above all, remember that integrity, expertise, and a customer-centric approach are the true keys to sales success. By keeping your clients‘ needs front and center, continuously sharpening your skills, and tuning out the noise of misguided tips, you‘ll be well on your way to becoming a trusted sales professional.

Now it‘s time to put this knowledge into practice. Identify one piece of bad sales advice you‘ve been guilty of following and commit to eliminating it from your repertoire this week. Focus your energy on replacing it with a tactic that better serves your customers. You‘ve got this!
