Business leaders look to marketing and sales teams to generate, qualify and nurture leads without necessarily considering how or where to find leads. But these leads don’t just come from anywhere random. The reality is that there are specific lead sources, sometimes called acquisition channels, where leads can come from.
The best lead sources are obviously those that provide targeted opportunities that match a buyer persona to engage with qualified leads and customers to convert more sales for your company. Identifying which lead sources perform best for your company can be challenging though and requires the right marketing tools, data analysis and insight.
It’s important to know which lead source channels perform best for your business so that you can focus your lead generation efforts and budget towards finding and nurturing quality leads with a higher propensity to convert customers for a product or service in a shorter period of time.
Here are 10 most common lead source channels for your business.
Your Database
Your existing database may represent a significant lead source for you initially, particularly if you haven’t engaged with your database in some time.
Even if you don’t have a large database of leads, or aren’t actively capturing them at the moment, your company likely still has hundreds of contacts spread across applications or locations, e.g. in email accounts or business cards collected. These people or prospects are still potential customers, so engage with them to identify any potential opportunities.
Tracking and nurturing leads is where a CRM plays a crucial role. With the right CRM software, you’ll be able to manage every lead from initial contact to close. When a database has become a large unsegmented list of contact details over time, investing effort in segmenting and lead tracking will deliver significant returns.

Your Website
Your website is the most significant marketing asset for b2b lead generation in your business. It’s where the value proposition and differentiation of your business is articulated.
Your website also represents the key hub of your marketing and demand generation. It is where you funnel most of your prospects and opt of funnel leads to. Many of your other lead source channels will point to your website to give you the opportunity to capture interest or intent from your prospects and leads. Website optimization can turn it into a lead generation tool, and optimizing for search engines ensures visibility to potential clients.
Organic search, or people finding your website by searching topics or researching answers to their questions online, represents a significant source of attracting prospects and leads to your website. Because 75% of users never click past the first page of Google search results, SEO-driven content marketing is critical for capturing inbound interest.
When your website is integrated with your CRM or marketing automation platform, you’ll be able to capture prospect details through visitor tracking and track how they interact with your content. With lead scoring in place, you’ll be able to identify Marketing Qualified Leads (MQLs) and Sales Qualified Leads (SQLs) for your sales team to engage with as prospects move through the buyer’s journey, helping distinguish an MQL from a sales qualified lead within the sales process.

Social Media
Social media can represent a great source for generating new leads by providing an opportunity to engage with net new prospects and transition them with content to your website, but social media channels do not contribute equally in B2B, and LinkedIn is widely considered the most powerful B2B channel for reaching a target audience.
While it would be your website and other channels that then converts and qualifies the lead, from an attribution perspective the original source would have been social media.
Around 80% of social media leads come from LinkedIn, which makes it the premier B2B platform for social selling and thought leadership.
It’s important to recognise that generating organic leads from social media requires an ongoing investment and has a medium to longer term time to impact. This is because it takes a longer time to reach and build up social audiences.

Digital Advertising
If reaching net new leads organically takes time, digital advertising represents a lead source that enables you to attract attention and put content in front of prospective leads at scale.
Digital advertising is used here as a catch all to encompass pay-per-click ads on search engines, paid ads or lead gen forms on social media platforms, and placing display ads or sponsoring content with media or trade publishers across both paid channels and digital channels.
A major benefit of digital advertising is you get all the metrics you need to monitor, optimise lead generation campaigns, measure ROI, and track which campaigns are driving leads, which sources produce the most leads, and overall lead volume.
Paid search and social advertising can also retarget visitors who did not convert, using landing page behaviour and intent signals to generate quality leads.
It’s important to remember that digital advertising requires an appropriate investment over dedicated periods of time. Nearly half of B2B marketing professionals allocate the majority of their advertising budgets to paid advertising, which reinforces the need for sustained paid marketing investment. Short bursts of activity with limited investments may not deliver the results a business is looking for when first starting out. If there is already a history of digital advertising, shorter-term or targeted campaigns can make a more rapid impact.

Traditional Advertising
Traditional advertising such as outdoor or print advertising can represent a lead source for a B2B business, though is more difficult to track and quantify results.
One tactic that technically falls into traditional advertising or traditional marketing that is important to consider is telemarketing and appointment setting. Within a broader cold outreach strategy, phone-based outreach represents a significant opportunity to reach leads fast through cold calling, lead nurture, and setting appointments for the sales team to qualify and convert. Accurate data and reliable contact data improve outreach efficiency and help sales reps connect with potential leads faster.

Referrals
Word-of-mouth referrals from existing or previous customers, including customer referrals, as well as from strategic partners, is one of the most ideal lead source channels for your business, and satisfied customers are often the source of the strongest word-of-mouth introductions. This is because the lead has already identified a need or pain point, has discussed this with a contact, and that contact was provided a warm referral or introduction to you business. Organic referrals are the direct result of customer service and product excellence.
Some studies attribute 54% of B2B leads to customer referrals, which helps explain why this source often produces high quality leads.
Creating simple, formalised scenarios to ask existing customers for referrals contributes to this lead source channel.
Partnering with businesses that deliver tangential services or products to the same buyer persona or operate in the same channel ecosystem and don’t directly compete with your business may be a good source of referrals. Developing a referral partner program to formalise and structure these referral relationships adds trust, ensures mutual value and may increase the lead referral volumes as a result.

Events and Sponsorships
Events such as webinars, presentations and ‘lunch ‘n learns’ represent a great source of leads when executed as part of campaigns. Used across the customer journey, they support generating leads while also helping build trust with existing customers. They enable you to immediately register some form of interest or intent and provide your sales team with qualified leads to engage and nurture.
If you’re participating in events such as conferences, trade shows or trade exhibitions where prospects or decision makers in your target market are likely to be, then sponsoring these events can be a great source of new leads and bolster marketing efforts when aligned to your wider marketing strategy. It’s important to remember that there are many other brands sponsoring these as well, so achieving cut-through and gaining attention will require clever planning.

Prospecting
Prospecting is part of b2b lead generation focused on identifying a b2b lead or account that matches your target market and pain points.
Prospecting involves searching and sourcing these good-fit prospects either manually or by other digital means to target with marketing activities. This is often the first step in an Account-Based Marketing (ABM) program, and reaching target accounts often relies on a sales intelligence platform, filtered compliant contact data from B2B contact databases, and intent data platforms that provide insights into organizations actively researching solutions.
Using intent data allows targeting of accounts actively researching solutions, while technology can streamline the lead acquisition process and an omnichannel approach is often needed to surface high quality leads and quality leads across marketing channels and outreach.

Your Sales Team
Each sales team member you hire will bring their ‘black book’ of contacts with them. These contacts could be some of your best leads. As sales leaders will know, this source of leads is limited, and the sales person will need to have impactful prospecting and other forms of sales development activities in their repertoire to hit their sales targets across shorter or longer sales cycles, with sales reps adjusting outreach based on where prospects are in the buyer’s journey. Cold email outreach and cold email campaigns work best when built on targeted lists, personalization, and a clear understanding of prospect pain points. Email campaigns and sales calls should use consistent lead source naming so sales and marketing teams can improve tracking lead sources across the sales process.

Want To Identify Which Lead Sources Are Performing Best For Your Marketing and Sales?
Every company always wants more leads, but lead volume matters less than quality leads, so you have to consider what kind of leads you’re getting and from which lead sources perform best for your business.
Tracking lead sources across the customer journey gives revenue teams, the marketing team, and sales and marketing teams better visibility into which channels create quality leads, which lead source categories deserve more budget, and how to shorten sales cycles.
For many businesses, email marketing remains one of the best lead sources and a high-ROI channel when focused on segmentation, while effective B2B lead generation usually combines outbound outreach with inbound content marketing.
