If you are a B2B company, lead generation (or Lead Generation) is the most important element in the growth of your business, without any doubt.

For this, there are numerous acquisition channels that you can activate. 19 in total (source: Traction book).

In these 19 lead generation channels, there are obviously offline channels (trade shows or the network for example), but also and especially digital channels that you can activate more easily. Zoom on one of these channels.

Lead generation: what does it consist of?

Lead generation or lead generation therefore consists in generating interest from people who can subscribe to your product or service.

The action that this person generally takes is to fill out a contact form to obtain a document, register or book an appointment.

In this form, she usually leaves her email or phone number, which is when this contact becomes a lead.

To do this, in B2B, we will generally target profiles who are “decision makers”. That is to say profiles that are likely to be interested and in addition to making the decision themselves.

Lead generation: the main digital channels

In digital, there are certain channels that will be very relevant for you:

  • Ads on media networks to generate leads : Google Ads, Facebook Ads, LinkedIn Ads. They bring more or less qualified leads depending on the audience and the channel, with a controlled cost.
  • Prospecting rather written by message, using LinkedIn or Cold Emailing. Once we have a base with our targets, which we will generally build up via scrapping on LinkedIn Sales Navigator, the goal is to send messages en masse and in a hyper-personalized way.

Why use a lead generation agency?

Lead generation agencies make it possible to activate one or more of these channels in order to increase the volume of incoming leads.

Agencies generally have 2 advantages:

1/ They are senior on the subject and have well-established processes allowing you to go faster in setting up and managing the various campaigns.

2/ They are generally less expensive than a busy salary: that is, if your objective was to hire one or more people to set up these acquisition channels internally.

What place does lead generation have in your overall marketing strategy?

If the process is proven, and brings results, these are acquisition channels that can bring you a lot of value:

  • Qualified leads (since targeted)
  • In the case of digital prospecting: no media budget spent, which is not the case for Facebook Ads (you can find the Top 5 best Facebook Ads agencies), Google Ads, or LinkedIn Ads.
  • Scalable: as leads can arrive regularly, you also have the possibility to modulate your sending frequency (email) or your budget (ads) to anticipate the number of leads you want to receive. This is generally very interesting depending on the evolution of your sales team and the time you have to give to incoming leads.
  • If your target is large, and you have an interesting average basket, there is a good chance that it will be very profitable.
