B2B lead generation strategies that still work

By Asen Levov, co-founder of Sellinger. Reviewed by Viktorio Shopov. Published . Last updated . 8 minute read.

Seven B2B lead generation strategies still work when they start from a specific reason to contact a specific person: signal based outbound, named owner letters, referral networks, partner surveys, fast answers to ad leads, live chat on your site and content that builds a profile people open. Each has a result in our case studies, from one account and one audience, so read them as examples to test.

Lead generation advice tends to list tactics with no numbers. Here we list the strategies we have run or seen run, with the figures and the limits, so you can choose by evidence. There is a longer treatment of building the list itself in how to build a B2B lead list.

1. Signal based outbound

How it works. You write to people who just did something that suggests a need: engaged with a relevant post, changed jobs, hired, raised money.

Evidence. On our own LinkedIn outbound, lists built from an intent signal replied at 54.6% and booked 4.54 meetings per 100 people messaged, against 21.7% and 0.71 for a Sales Navigator search. Over 12 months our own account booked over 1,500 calls, using on average 7.5 LinkedIn accounts.

Limits. The audience inside the signal decided the result: engagers with AI SDR vendors' posts booked 2.6% to 3.7% per person, engagers with enterprise sales voices under 0.4%. See signal based against database prospecting.

2. Named owner letters

How it works. A short, formal letter to the person who owns the problem, with one question at the end.

Evidence. Green Shield Logistics: named heads of quality, ESG, procurement and logistics replied at 8.2%, almost four times the 2.2% of clinic and lab inboxes, and produced 17 of the 18 positive replies. 11 replies forwarded the letter to the responsible colleague.

Limits. 546 organisations, one regulated sector.

3. Referral networks

How it works. In a market that runs on trust, you recruit the people others refer to, writing as a peer.

Evidence. The wealth advisor network messaged 9,808 professionals; 44.8% replied and 33.7% replied with more than a pleasantry. 95 calls were booked and corroborated, April to August 2026.

Limits. Profiles run for individual member firms replied at 27.4% and booked under 1%. Who you recruit matters as much as how.

4. Partner and customer surveys

How it works. Ask an existing base four numbered questions by email.

Evidence. Shelly Group emailed 3,940 installers in 111 countries: 13.6% replied in the June to August waves, against 3.3% for the first email alone. 360 replied, 225 answered the survey and 64 flagged a big project.

Limits. A listening programme to an existing partner base, not a cold campaign. 51% of installers replied in a language other than English, so the agent wrote in 21 languages.

5. Fast answers to ad leads

How it works. When a form is filled, contact the person at once. Sellinger polls Facebook lead form leads every 60 seconds and Google Ads leads every 300 seconds, creates them as leads and contacts them through the campaign, with Google Ads leads defaulting to WhatsApp as the first channel.

Evidence. We have no published conversion result for ad leads. The reasoning is speed: on our own LinkedIn outbound the median agent reply was 2.3 minutes since May 2026, and 48% of prospect messages arrived at night or on weekends. See speed to lead for ad leads.

Limits. The ad and the offer decide the volume. Speed only saves the leads you already paid for.

6. Live chat on your site

How it works. An agent answers visitors, qualifies them and books meetings, day and night.

Evidence. At our own hotel the reservations agent answered guest inquiries with a median first reply of 41 seconds over 54 inquiries. We have no published result for a B2B website widget.

Limits. It needs traffic. See live chat against chatbot against AI concierge.

7. Content that builds a profile people open

How it works. Posts that show what you know, so that the prospect who opens your profile after a message finds something real.

Evidence. We make no claim that posting raises outbound results, and have no measurement linking post timing to outreach results. The reasoning is that each person messaged in our own campaign could open the sender's profile before replying.

Limits. Slow, and hard to measure. See a four week LinkedIn content calendar.

How do you choose?

Table
Buyers talk about the topic on LinkedIn1, signal based outbound
A few named buyers in a regulated field2, named owner letters
Trust and referrals drive sales3, referral networks
You sell through partners4, partner surveys
You already pay for ads5, speed to lead
You have steady website traffic6, live chat

Pick one. Run it on 100 to 200 people. Read every reply for a week. Then add a second strategy and measure it on its own.

What goes wrong?

  • Running everything at once. You cannot tell what worked.
  • Counting leads, not meetings. A list of 5,000 leads that books nothing is not lead generation.
  • Ignoring the audience. Our data showed audience beat wording tenfold.
  • No follow through. A reply that waits a day often goes cold.

How do the seven compare on effort and speed?

A qualitative reading of the examples above, not a measurement across campaigns.

7. ContentMonthsConsistencyNo way to measure

Which two combine well?

Signals and a second channel. Start with strategy 1, and for people who never saw the first message add email. The sequencing is in a multichannel sequence that works. A second pairing is strategy 5 with a clear handoff, since the lead you paid for is lost if nobody answers.

What should you not combine?

Do not start two strategies in one week on the same audience. If a person receives a letter, an invitation and a chat message, you cannot tell which one worked, and they notice. Run one, read the replies, then add another.

How do you measure each one on the same scale?

Use meetings held per person reached, with the denominator written next to it. The examples above report different things: meetings per 100 messaged, reply rate, positive replies, inquiries. Convert your own results to one line:

People reached ___, replies ___, positive replies ___, meetings booked ___, meetings held ___.

With that line for each strategy, you can compare them without arguing about definitions (count meetings honestly).

What should a small team do first?

If you have a LinkedIn account and a clear buyer, start with strategy 1 on 100 to 200 people with approval on. If your buyers are named and few, start with strategy 2. If you already pay for ads, start with strategy 5 before any outbound, since the lead has already been paid for. Everything else waits for a month of data.

Are these strategies new?

No. Letters, referrals, surveys, quick answers and content are old methods. What is different is the cost of doing them with care at volume. An agent can write to each person in their own words and answer at night, so the advice that used to need a team of five can be tried by one person. That is the reason to test them now with your own list, and to keep the numbers above as examples, not promises. Search for the longer list-building steps in how to build a B2B lead list.

A checklist

  • [ ] I picked one strategy that fits my market.
  • [ ] I have a specific reason to write to each person.
  • [ ] I measure meetings held per person messaged.
  • [ ] I read every reply in the first week.
  • [ ] I treat these numbers as hypotheses to test on my own list.

Common questions

What is B2B lead generation?
Finding and attracting businesses or business people who may buy, and getting them into a conversation.
Which strategy is best?
The one that fits your market and your capacity. In our data signal based outbound did best on LinkedIn, but a referral network or a named owner letter fit other markets.
Is outbound still worth it?
Our own account booked over 1,500 calls in 12 months using on average 7.5 LinkedIn accounts, so yes for us. The audience and the offer decide it for you.
What about paid ads?
Ads create inbound leads that decay quickly. Sellinger polls Facebook lead form leads every 60 seconds and Google Ads leads every 300 seconds so they are contacted at once.
How many strategies should I run?
One or two at first. Add another when the first is steady and you can measure each separately.
