What to consider before hiring lead generation companies

What Are Your Needs?

Sure, if you’re looking to hire an agency because you just want more targeted leads, that’s fine.

But before you hire a lead gen agency, you have to ask them what they plan on doing for you and how they plan on doing it.  

For example, you might want them to come up with a sales development strategy that you will use to get leads.

You might be in a place where you’re not 100% sure of what’s the best way to find potential customers. Should you use LinkedIn, cold emailing, or SEO?

Maybe it might even be via cold calling or Facebook and TikTok ads.  

We suggest taking a step back and first see how much strategic help you will need to put a successful marketing campaign in place. 

So, unless you already have a prospect list that’s already responding to your messages in your sales process, you will need a lead generation service that will help you develop a strategy that works specifically for your business. 

If you know that you need a strategy, ask the company that you’re thinking of hiring whether they will be able to provide you with a strategy. 

A Sales Call Isn’t Always The Best Place To Pick B2B Lead Generation Companies

You know you’re looking for a lead generation company. 

Do you really want a 30-minute sales call where (god forbid) they just bore you with a monster slide deck, where you don’t get to talk about what you really need? 

That’s not enough to understand if you have really found the right lead generation partner. 

This is why at Salesbread we encourage our prospects to start with a risk-free consult. 

And I tell them very plainly that this is a small step towards working together. 

This puts all the risk on us. 

And if the call didn’t go as well as you hoped for, we will refund every penny. 

But I do ask for a detailed marketing survey to be filled out before we meet so that I have a chance to show up with notes. 

And the reason why I’m explaining this process in this way is…

Maybe you should ask the lead gen agency if you could do a small trial project before settling in on them. 

So ask your potential lead partner if you can start with a risk-free consult; that way, it should give you and your team a lot more confidence in them than just a quick 30-minute call. 

Think About Your Requirements For The Lead Gen Campaigns

Know what your campaign requirements are. You want to find out how you’re going to get insights on your campaigns.

How are you going to track things that you want to find out? The agency should be able to provide you with campaign insights. 

So be upfront about what you expect. 

Take A Look At The Lead Generation Agencies Resources

Do they have a podcast? If you listen to it, does it sound like they know what they are doing? 

Read their articles. Do their strategies make sense?

Watch their videos, read their case studies, and see their approach to generating leads.

These resources can tell you so much about the company that you would like to hire.

You need to see if their strategy aligns with yours, so the best place to find this out is to check out their content. 

Ask these questions to choose the best agency for your business

Who Is Going To Be My Account Executive?

Typically, you won’t be dealing with the founder of the agency (unless you hire Salesbread, where you work along with Jack Reamer.), but in many cases, your account might be handed over to a junior account manager.

If you’re comfortable with that, then that’s okay, but frankly, I have never been comfortable with that.

That’s why, as the founder of Salesbread, I’ve always handled my clients’ accounts.

I’ve been doing this for 10 years, and my clients work directly with me. 

I’m the strategist, copywriter, and account manager. I ensure that each campaign is handled in the right way and is triple-checked. 

So if you need a strategy, make sure that you find out who the team is and how they will help.

Who retains ownership of the leads that have been generated?

Be wary of lead generation companies that say they will retain full ownership of the leads.

Why?

Because it might limit how you can use these leads. Rather, opt for a lead gen partner with transparent policies about who has ownership of the leads and a clear pathway for ownership transfer.

Is there a long-term contract?

Be wary of companies/marketing services that want you to sign a long-term contract.

When you do lead generation the right way, it really doesn’t take a lot of time to get results. We tell clients to expect their first lead within 48 hours after we launch their campaign.

Why would an agency lock you into a long-term deal?

They should impress you on the first risk-free consult, and then the first month should warrant a second month and a third month.

So ask them if they keep clients based on performance alone. 

If they do, then there’s no need for a locked-in contract.

What type of leads will they generate?

There are different types of leads.

Some leads might be booked appointments, other leads might mean conversation starters and other leads might be booked demos.

You need to get very clear about what the agency means by “lead generation.” 

Double-check if the company is just getting people to respond to your products or if they will actually book the appointments for you.

What Are The Benefits Of Hiring a Lead Generation Service?

If you’re a start-up or a founder who doesn’t have a sales and marketing team just yet, outsourcing your lead generation can ensure new leads for your company relatively quickly. 

For example, at Salesbread, we promise our clients that they will have their first qualified sales lead within 48 hours of launching our LinkedIn outreach campaigns. 

You might also prefer hiring B2B lead generation companies if lead generation isn’t your strong point. Perhaps you don’t enjoy cold calling or email outreach … Or maybe you don’t have the experience to generate high-quality leads. 

Hiring an agency allows business owners to have more flexibility because they won’t have to generate leads themselves. 

All you need to do is focus on closing deals. 

You will also save time and money because you won’t have to pay salaries and train up a new sales team. 

Hiring an agency might also be beneficial if you don’t have the experience to generate leads for your company.

These companies mentioned below have the experience and resources to build your ideal customer profile, do the market research, and generate qualified leads for your business. 

There are various options available. 

From outreach agencies to appointment-setting companies and even digital marketing specialists. 

Here Are Some Other Reasons Why Hiring B2B Lead Generation Companies Could Be A Good Option For Your Business:

• You will close more deals faster due to the quality of the leads being sent your way.
• A lead generation agency can handle high pressure in sales.
• Increased data optimization for your company.
• You will have more time to focus on aspects of your business that you enjoy.
• You will have access to specialized tech
• Your employees will have more time
• Quick growth and more sales.

However, many companies hold off on hiring an agency because they worry about costs.

It’s important to note that hiring an agency initially can be more cost-effective than building your own in-house SDR team. 

The average salary of an experienced SDR in the US is about $81,614 per year. This doesn’t include things such as office equipment, data, office space, specialized tech, and refreshments. 

On average, most lead generation agencies cost between $1000 – $10 000 depending on which service you choose. 

Note: Services such as SEO and social media marketing can be more expensive, ranging between $3000 – $20 000 per month. It also takes time for these services to take off. So, you might end up waiting a while for conversion rates to grow.

• Build Your B2B Lead Generation Team: In-House VS. Outsourced

Should You Choose An Inbound Or Outbound Lead Generation Company?

The choice really depends on your company’s needs and budget. 

Some b2b lead generation companies might use a mix of both marketing methods or just one.

The important thing to remember is that inbound methods take time to generate leads. Meanwhile, with outbound, leads can come in almost instantly. 

We suggest using a mix of both marketing methods because while waiting for your inbound strategy to take off, you can generate some outbound leads. 

This article delves into more detail: Inbound vs. Outbound Lead Generation. Feel free to read it if you aren’t sure which option is best for your company.

What Services Do Lead Generation Companies Offer?

• Lead research
• Custom lead generation campaigns
• Lead management
