You might have heard somewhere that lead generation strategies can make or break your business in today’s competitive marketplace. Without a solid one, you are wasting valuable resources trying to sell in the dark.

However, do you know that 61% of marketers say generating high-quality leads is their biggest challenge?

As the process of generating leads is becoming difficult and complicated, many brands opt to outsource their lead generation programs to one of many companies specially set up for this purpose.

So, in this guide, we will take you through the exact definition of lead generation, the top 15 lead generation companies, and finally, how to choose an appropriate company.

Read until the last words, and you’ll find amazing things!

What is lead generation?

As a matter of fact, the concept of a lead might be surprisingly complex. There’s no wonder why so many marketers and business professionals still ask themselves, “What is a lead?”

So, to make it simple, a lead is another word for a prospect. To be specific, a lead is a prospective customer of a product or service, created when an individual or business expresses interest and then provides contact information.

To capture these leads, you need to leverage different marketing tactics that will make users sign up for something online by filling in a form, directly contacting your business, or even walking into your physical store. And this process is called lead generation. Integrating a lead generation CRM system can help you efficiently manage and nurture these leads to convert them into loyal customers.

For instance, your company has created an ebook to serve as a valuable source of information to potential new customers. A user that submits his/her information will receive something of value in return - in this case, your e-book. This user is now considered a lead in your marketing database. The goal of a successful lead generation strategy is to obtain new leads, or leads that fit target customers that your business defines.

How do lead generation companies work?

Lead generation can require a lot of work and effort to implement; therefore, many small and medium businesses are now outsourcing their lead generation to companies who specialize in attracting and converting potential consumers into buying ones.

Lead generation companies provide your companies with the necessary leads you want to attract new clients. At the same time, you can free up your time to spend on other essential tasks, such as product development or quality assurance.

A lead generation company, firstly, develops a website or partners with different websites on which they promote and advertise your products or services. A customer finds these informational sites and directories, then hopefully completes an online request form. The customer’s information is eventually verified and matched to appropriate providers.

The ultimate goal of these companies is working as a third party to generally set up appointments for potential customers to have conversations with your sales team.

Advantages of hiring a lead generation company

Many companies can handle lead generation on their own. However, as stated above, it can take a lot of time and effort to do research and implement. Meanwhile, there are many benefits when working with a lead generation company, instead of attempting a DIY (Do It Yourself) approach.

Some of the advantages of hiring a lead generation company include the following:

  • Access expert assistance. Businesses can make the most of experts who already have in-depth knowledge and tools to bring in quality leads.
  • Stay focused on results. By having an agency drive new leads to your company, you can focus on other goals, initiatives, and priorities.
  • No more cold calling. Do you know only 2 % of cold calls result in an appointment? So, when working with a lead generation agency, your company can spend less time cold calling, as well as more time talking to prospective customers who are ready to make a purchase.
  • Handle leads effectively. How to handle leads after they’re obtained makes a huge difference. Hence, lead generation companies can create a follow-up strategy that helps businesses know what to do with each lead to gain more sales.

How to choose an appropriate lead generation company

There are more and more lead generation companies to choose from today; hence, finding one that helps generate more quality leads is crucial.

In the last part of this guide, you’ll know how to make sure that you don’t waste time and money on bad leads from lead generation companies, which don’t know what they’re doing.

Check the company’s experience

Generating leads for an e-commerce company cannot be the same as for a software company. Similarly, generating B2B leads will require a different approach when compared to B2C leads.

Check the company’s experience
Check the company’s experience

So, you can check the experience of a lead generation company by learning more about what businesses they’ve partnered with in the past, as well as the results. Besides, you should keep in mind the significant differences between the companies they’ve worked with. By doing this, you can understand how flexible they are with their approaches and strategies. It also shows whether they can customize their services to provide better results for their clients.

Find out how they get leads

The quality of the leads is likely to vary based on how they get them. For example, they have telemarketers randomly call customers to build a list of leads; those leads probably won’t be very good.

Instead, if they approach customers by using a comprehensive content marketing strategy, they may help bring in more high-quality leads. Or in some cases, leads that come from consumers filling in forms for more information may lead to more sales than from telemarketing.

Lead generation companies usually use different methods and channels to generate leads. However, each business requires a unique approach, making some methods suitable and some not. Therefore, before signing a contract with a lead generation company, you should make sure to understand how they get qualified leads for your companies.

Look for quality, not always quantity

Quantity is important, but when it comes to lead generation, quality is far more essential. Of course, businesses desire to bring in as many leads as possible, so they can try to get more sales. However, when the focus is just the quantity, the majority of those leads may be low-quality, which means they are not likely going to result in a sale.

Look for quality, not always quantity
Look for quality, not always quantity

So, make sure you choose a company that focuses on quality leads in order to cut down on wasted time and boost the number of sales. You can refer to our list of 15 lead generation companies in the previous part to make the best decision.

Check how to handle reporting

Reporting is an indispensable component of lead generation. Businesses need to know how effective the service is, how many leads are generated per month, how many of them are qualified leads, and how many sales are made. This makes it easy and transparent to see the return on investment and follow what is actually happening.

Therefore, it would help a lot if you choose a company that is going to provide a regular and detailed report with a thorough analysis. By doing this, your company can discuss with the lead generation company and determine if there are any changes or improvements or not.

Read customer reviews

When being in doubt, you can read client reviews, feedback and testimonials about the lead generation company that you are targeting. Some popular websites are available and trustworthy, such as Clutch, Google Reviews, and so on. Besides, you can learn more on social media channels, forums, and independent resources to know more about their services and ratings.

The bottom line

Generating leads may be a challenge for many companies, but it is an integral part in the process of growing and developing. Given the importance of lead generation, more and more brands chose to rely on lead generation companies for this tough and challenging task.

There are dozens of lead generation companies in the marketplace, and as you can see by the list above, each one has something outstanding and different to offer. When you research the top lead generation companies, be sure that you have clear business goals and understand your customer base. By discussing this kind of information with the lead generation company, you can start building a plan and set benchmarks that not only increase leads but sales as well.
