Lead Generation Agency or Software: Find What Works for You?

Many marketers might mistake lead generation software for agency and vice versa. But they're not the same. In this section, let's understand the key differences between a B2B lead generation service and software.

Lead generation companies offer personalized service and expertise in crafting tailored strategies, which is beneficial for companies without in-house expertise. Such agencies also work well for businesses with a limited budget or those looking to scale quickly.

Factors to Consider While Choosing a B2B Lead Generation Agency

Choosing a befitting lead generation service is like selecting a partner for a dance marathon. You want someone who understands the rhythm of your business and moves to the same beat.

As we shuffle through these options, let's consider the key factors that ensure your lead generation agency is a step in the right direction.

  • Look for an agency that specializes in your industry. Go through a prospective agency's website to learn about their list of clients. Are they from your niche? Then, you must consider hiring this prospective agency for B2B lead generation services.
  • Assess their track record in delivering high-quality leads. Don't forget that lead quality is a significant factor when choosing a lead generation company.
  • Ensure they maintain accurate contact data to avoid wasting time on incorrect leads.
  • Seek transparency in their processes, pricing, and reporting.
  • Look for agencies that tailor their approach to your unique needs.
  • Effective communication is essential. Choose an agency that keeps you informed and collaborates closely.
  • Remember, each business has different requirements, so choose a service provider that aligns with your lead generation goals.

Advantages of Hiring a B2B Lead Generation Agency

As a B2B sales and marketing leader, are you struggling to generate high-quality leads consistently and at scale?

Enter the lead generation outsourcing: your lighthouse in the mist. B2B marketing agencies aren't just vendors but partners in your journey towards sporadic business growth.

With an in-depth understanding of the B2B landscape, they navigate through the noise to bring you closer to your most sought-after prospects.

By outsourcing lead generation, B2B companies can focus on their core competencies and ensure their pipeline is brimming with potential.

It's a strategic move to leapfrog and achieve extraordinary business outcomes.

  • A B2B lead generation company has experience and expertise in helping you build relationships with the right prospects at the right time. They have access to technology and people to execute scalable lead-generation campaigns cost-effectively.
  • A lead generation service provider allows you to run or stop campaigns based on your business requirements. The costs associated with an in-house team are fixed and often significantly higher. Hence, outsourcing lead generation can be a huge cost saver for your B2B business.
  • Agencies bring in-depth knowledge of market trends and customer behaviour. Therefore, they can create the right messaging for you to generate the best quality B2B leads for your business.
  • Hiring a lead generation partner can help you run campaigns on multiple channels simultaneously. For instance, you can use email, LinkedIn, content marketing, paid campaigns, and cold calling to get prospective customers into your funnel.
  • By hiring an external lead generation service, you automatically reduces your risk of investing in non-performing marketing strategies, as you pay only for the leads the agency generates for your business.

How TripleDart Helped SpotDraft Achieve a 400% Increase in Demo Bookings

About SpotDraft

Documentation can be mind-numbing work, especially when it comes to tedious legal documents with multiple clauses, subclauses, and so on. SpotDraft aims to solve this problem and positions itself as a provider of Contract Management Systems for legal teams.

In August 2023, SpotDraft partnered with TripleDart Digital to generate qualified leads at scale.

How TripleDart Executed Quick-Win Strategies for Better Leads

We adopted a targeted approach and focused on quick-win search campaigns. Initially, our emphasis was on BoFu (Bottom of the Funnel) campaigns. To empower these campaigns, we created well-designed landing pages and optimized them with targeted keywords. As part of the expansion strategy, we also targeted new regions, including APAC, EMEA, and NA. We recognized NA's highly competitive landscape, where ROI could be challenging. So, instead of directly competing in the region, we focused on leveraging MoFu (Middle-of-the-Funnel) content to generate leads.

We also used dynamic search ads to target downloads in the initial phases and attracted leads for MoFu content pieces such as downloadable reports, templates, and checklists. All this allowed TripleDart to efficiently navigate difficult markets and maximize B2B lead generation for SpotDraft.

Conversion Rate Optimization (CRO)

At TripleDart, we implemented strategies to enhance the quality of incoming traffic by focusing creating value-driven content. We improved the website content and refined the ad copy to increase traffic and attract higher-quality leads. We created customized landing page messages to achieve higher rates of conversions.

Strategic B2B Lead Generation

We implemented effective pipeline management strategies to scale pipeline growth, focusing on lead nurturing and conversion optimization.

Our team also focused on identifying missed opportunities and getting the ideal buyers to enter SpotDraft's sales pipeline. We expanded into new regions and implemented strategies to capture a larger market share.

The efforts proved fruitful, and TripleDart Digital helped SpotDraft achieve a 400% increase in demo bookings and scaled pipeline growth from $22,600 to $163,300.
