Seven benefits of lead generation companies

There are many benefits you can reap from working with a trusted provider of lead gen services, but here are the top seven:

1) Better lead quality

One of the main reasons why B2B lead generation firms exist is because of their ability to spot the best and most relevant leads for your company. They achieve this by assessing vital elements such as lead demographics, online behavior, and search intent.

2) Greater reach

Usually, business lead generation companies have comprehensive databases of potential leads that span many industries and locations. This means that they can help you pinpoint the right contacts for you literally at the touch of a button.

3) Enhanced brand awareness

Working with a lead generation company can get your brand out there in a more impactful way, thus boosting views, reach, engagement, and overall brand awareness.

4) More conversions

Once a lead generation company has identified a range of high-quality, relevant leads, it will keep supporting you in attracting and nurturing them so they eventually convert into loyal, returning customers.

5) Higher scalability and flexibility

Do you plan on breaking into a new market, launching a new service, or expanding your operations abroad? With the right lead generation company by your side, you’ll gain the level of scalability and flexibility that your business goals and strategy require.

6) Increased cost-effectiveness

While the upfront cost might seem high, working with a great lead gen company will pay off in the long run. Doing everything in-house can end up being a lot more costly (not to mention complicated and time-consuming), while a lead generation firm takes care of everything on your behalf.

7) More time for strategic work

As a natural follow-up to the previous point, working with a lead gen firm will also enable you to free up time and resources to focus on value-added business processes, such as product or service development and delivery, personalization, and customer service.

How to choose the best lead generation company for your business

The above are just some of the many benefits lead generation for companies in the B2B industry can bring. Now, before selecting the best lead generation company for your needs, consider the following aspects:

Legal compliance

One of the essential things to think about when choosing the best lead gen firm to work with is, no doubt, whether they comply with all the relevant standards and requirements in terms of data protection, such as GDPR and CCPA. 

They should have a solid data privacy policy, which includes personal data consent, opt-out options, and more.

Lead relevance

Usually, lead gen companies don’t offer one single lead generation service—they have a portfolio that includes a wide range of options. 

Once you’ve narrowed down your search for the best lead gen company for your business needs, check the company’s service offering and make sure what it does is really relevant to what your business needs. 

Does it have expertise in your industry? Is the company interested in what you provide? Do the leads it identifies fit your target audience?

Pricing

Of course, money is a crucial part of the selection process. First of all, make sure that the pricing options offered are transparent and easy to understand. 

Then evaluate the cost-effectiveness of the service by calculating how much each lead will cost you. Lastly, check if they have the option for customized pricing plans, as these might work out much better for your needs.

Lead ownership

Do you know who owns the leads generated by the lead gen company? Once again, transparency is vital. 

In some cases, these companies choose to retain lead ownership, which makes it hard for you to use them in the way you’d need. Before sealing a deal with a lead generation firm, ensure that you’re aware of—and happy with—their policy around lead ownership.

Flexibility

As we mentioned earlier, one of the main benefits of working with a lead gen company is the high flexibility that it can offer. For this reason, you should opt to work with a firm that’s willing to match your lead generation requirements over time and as you grow, as well as try out different techniques to generate the best leads.

Are B2B lead generation companies compatible with most software?

Most lead generation software is compatible with other software tools, which enables B2B companies to avoid data silos and foster more productive and streamlined workflows.

These are some of the most common integrations offered:

• Analytics and reporting, such as Google Analytics, Looker, and Tableau

• CRM systems, such as HubSpot, Pipedrive, and Salesforce

• Marketing automation platforms, such as ActiveCampaign, Marketo, and Omnisend

• Sales enablement tools, such as Groove, Outreach, and Salesloft

Always check the integrations offered by any lead generation company you are considering to avoid vendor lockin.

How much do lead generation companies cost?

Most lead generation success stories you hear or read will include a mention of the price customers had to pay to achieve their goals, so it’s natural for you to ask, “How much should I pay for lead gen services?”.

The answer is far from clear-cut; some agencies will charge you a set price per month or year, whereas others will offer customized pricing plans that adapt to the specific requirements of their clients. 

Generally, prices can range from $60 to thousands of dollars per month, and this depends on factors such as:

• Lead quality and volume: The more leads you need and the higher granularity you look for, the more you’ll likely be charged.

• Service scope: Prices also vary depending on whether you’re seeking basic lead gen services or full-funnel support with add-ons like content creation, appointment setting, and lead nurturing.

• Industry and audience: More niche or competitive sectors might need more specialized lead generation services, which often come at a premium.
