Important Factors When Choosing  A Lead Generation Company

Lead generation, by definition, is a relatively simple concept involving three key processes:

  1. Attracting people to your brand (or in most cases, your website/landing page)
  2. Capturing their contact information, effectively converting a random visitor into an actual lead/prospect
  3. Figuring out whether this lead is qualified and worth nurturing (lead qualification).

So, when choosing a lead generation company, we should consider their expertise in these three main processes, namely:


1. How They Actually Attract Visitors

Lead generation companies can use many different approaches to attract and engage with prospects. So, figuring out their approach can be a major factor in determining your choice.

Remember that not only the quantity of the leads is important, but also the quality. So, the process can be really important here, and those that focus on assessing and capitalizing on purchase intent are generally the most reliable. Here are some of them:


  • Telemarketing

Pretty self-explanatory. The lead generation company calls their contact database to measure their interest. While telemarketing might seems old-school for this digital age, it’s actually a very effective personal approach where the company can measure potential interest for specific products/services.


  • Content Marketing

Another effective approach nowadays is attracting prospects through content marketing. This is very effective since the lead generation company can establish the client’s position as the expert of the niche, attracting more qualified leads in the process.

Generally, in this approach we use lead magnets to capture the content reader’s information, for example by offering a more in-depth content in the form of ebook or white paper in exchange of their email addresses. Content syndication, which is publishing your content in third-party sites in exchange of leads.

Usually companies who use this approach will also provide content development and SEO consultancy services.


  • Nurture Campaigns

Here, the lead generation company nurture an existing contact list to convert them into actual leads. The company can use email marketing, online surveys, phone calls, and other approaches to engage the potential prospects.

The goal here is to create a new list consisting of more qualified prospects where your sales team can convert more effectively.


  • Database Mining

In this approach, the main goal is to “mine” new contacts through various methods including using software and programs to crawl public records and existing databases.

The technology used by the companies can greatly vary (and can sometimes be a scam). So, if a lead generation company offers you this kind of service, make sure to have them demonstrate their approach and learn about it as much as you can before making a decision.


2. Quantity and Quality of Existing Database

Besides generating brand new, organic prospects for your business, some lead generation companies will offer to sell their own contact database.

It’s important to understand that in general, organic contact lists (the ones generated from various methods we’ve discussed above) will perform better than these third-party databases. However, these databases can still produce great results when used properly and when they fit your buyer persona.

It’s important to consider both the size of the database and whether the prospects in the list are aligned with your ideal audience. Buying these leads can be very expensive, and so it’s important to only buy those with the highest chance of conversions.

Some companies will push you to buy these leads, even when they don’t have a campaign that can fit your needs. Avoid these companies, and make sure their database is properly aligned with a program that fit your business.


End Words

The most important thing when trying to find the right lead gen provider for your business is credibility—a proven track record—. It’s also important to find the right fit for your business, an agency whose programs can align with your overall business and marketing needs.

Also, think of outsourcing to a lead generation and marketing consultant as a long-term investment. While it might cost you significantly at first, when done right it can provide you with a sustainable, long-term source of growth.
