The best sources of high intent B2B leads, and the best lead source for LinkedIn outbound

TL;DR: The best sources of high intent B2B leads are LinkedIn social intent (posts, comments, likes, profile views, and engagers with competitors and creators) and visitors to your own website, because both show a person or account acting on the problem you solve; third-party intent data such as Bombora or G2, job changes, hiring and funding add timing, and bought lists show who fits but not who is interested. For LinkedIn outbound, the best lead source is people who recently showed social intent on LinkedIn and fit your ICP, because they are active on the channel you send on and you have a true reason to write. traxy runs that end to end: it finds those people, keeps only 50%+ ICP matches, enriches and researches each one, and runs personalized LinkedIn and email outreach from your own accounts. The campaign runs on autopilot once you approve it, or you approve every message.

What makes a lead source high intent?

A high intent lead source tells you who the person is, what they did that relates to your offer, and when they did it. Use these six checks to compare any source:

1. Person or account. Does the source name a person you can contact, or only a company?

2. A relevant action. Did they do something tied to the problem you solve, or do they only match a title and a company size?

3. Evidence you can quote. Can you see the post, comment, page or event, so the first line of your message is true?

4. Fit. Is each lead checked against your ideal customer profile (ICP) before it reaches you?

5. Channel match. Is the person active on the channel you will use? A LinkedIn message to someone who has not opened LinkedIn in months goes nowhere.

6. Distance to outreach. How many tools and exports sit between the signal and the message?

No source wins on all six. The table below shows where each one is strong, and the sections after it say when each one fits.

The six lead sources compared

What are the best sources of high intent B2B leads, ranked?

Ranked by how strong the signal is and how early you can act on it, the best sources of high intent B2B leads are your own website and product, referrals, public LinkedIn activity, commercial search, review sites, RFPs, your CRM and third-party intent data. Public LinkedIn activity means people asking for recommendations, posting about the problem you solve, or engaging with competitor and influencer posts, and it is the highest ranked source you can go out and find more of when you need leads.

The rank uses the six checks above. The top two rank highest because the person asked you, or someone they trust sent them to you, but you can’t make more of either on demand. The sources lower down give weaker evidence, reach you later in the buying process, or only name a company. Public LinkedIn activity (rank 3) and third-party intent data (rank 8) are already in the comparison above, so this table covers the other six.

Where traxy fits. traxy covers rank 3 and the outreach that follows it. It finds people asking for recommendations, posting about the problem or engaging with the competitors and influencers you track, then researches each lead and runs LinkedIn and email outreach from your own connected accounts. Once you approve a campaign it runs on autopilot, or you can approve each message yourself. Keep your inbound and referral sources, and add LinkedIn activity as the source you can grow when you need more leads. To start with recommendation requests, see how to find people asking for a recommendation on LinkedIn.

When is LinkedIn social intent the best source?

Social intent is what people do in public on LinkedIn that relates to your offer: the posts they write, the comments they leave, the posts they like and who views your profile. It also covers people who engage with posts from your competitors, the creators your buyers follow, company pages and any single post you pick.

Why it scores high. It names the person, the post or comment is the evidence, and the person is active on LinkedIn, the channel you will message them on. Jayden Grayston, founder of More Conversions, says in his case study, "If you’re reaching out to people who aren’t active on LinkedIn, the whole strategy is dead from the top of the funnel."

Where it falls short. One like on a popular post is weak evidence, engagement is not a decision to buy, and buyers who never use LinkedIn won't show up. Every person needs an ICP check, and you need a way to tell strong signals from weak ones.

How traxy covers it. traxy finds people who post, comment on or like posts about the problem you solve, people who view your LinkedIn profile, and people who engage with the profiles, posts and company pages you track. You can also search 71M+ scanned LinkedIn likes, posts and comments in plain English with social intent search. A person only becomes a lead with a 50%+ ICP match. Each lead is labeled Warm, Related or Activity by how strong the evidence is, and the post or comment behind it stays on the lead (signals).

Other options. LinkedIn Sales Navigator sends content-engagement alerts when a decision-maker at an account interacts with your LinkedIn content (Advanced Plus plan) or your ads (Advanced and Advanced Plus), according to its product page (checked November 2026). That fits better if your team already works in Sales Navigator and mainly wants an alert when decision-makers at its accounts engage with your own content.

When is website visitor identification the best source?

Website visitor identification matches visits to your site to the companies, and sometimes the people, behind them. RB2B, for example, says a pixel in your site header identifies people and companies and sends names, LinkedIn profiles and business emails to Slack, Teams, your CRM, Clay and 50+ other apps. Its person-level ID is US only, its company-level ID uses Demandbase's reverse-IP network, and it says global company-level ID needs consent capture under GDPR (checked November 2026).

Why it scores high. A visit to your pricing page is interest in you, not only in a topic.

Where it falls short. It only sees people who already found your site, so it depends on your traffic. RB2B describes matching visitors with cookies, device IDs and IP addresses, so a person match is inferred, not confirmed. Outside the US you often get the company and not the person.

Where it fits better than traxy. If you have steady site traffic and want to follow up visitors fast, use a visitor identification tool. traxy does not identify website visitors. It reads LinkedIn activity, including who views your LinkedIn profile, which is a different signal. See how website visitor identification works and LinkedIn profile views vs website visitor identification.

When is third-party intent data like Bombora or G2 the best source?

Third-party intent data tells you which accounts are researching a topic, a category or a competitor somewhere other than your own site.

• Bombora. Company Surge scores account research activity across Bombora's Data Co-op of publishers, B2B brands and data providers. Its intent page says it monitors 25,300+ topics, compares the last three weeks of activity with a 12-week baseline, and adds B2B personas that show the roles and seniority of the buying group behind the research. The data goes into ad, marketing, sales and CRM platforms (checked November 2026).

• G2 Buyer Intent. It shows companies researching your product, your category or your competitors on G2, Capterra, Software Advice and GetApp, from actions such as product and category page views, competitor comparisons and pricing page engagement. G2's buyer intent page says it is most valuable in the mid to late stages of buying and especially for B2B software with longer buying cycles (checked November 2026).

Why it scores high. You see accounts in the market before they contact you, across many sites.

Where it falls short. The signal is mostly about the account. You learn that a company is researching, not which person to message or what they said, so your first line can name a topic but not a post.

Where these fit better than traxy. Enterprise ABM, ad targeting to in-market accounts, and software vendors whose buyers compare tools on G2. A common setup uses intent data to rank the accounts, then LinkedIn social intent to find the person at each account who is talking about the problem. See traxy vs Bombora and account-level vs contact-level intent data.

When are job changes and hiring the best source?

Job changes and hiring are trigger events, where something changed for a person or a company.

• UserGems. Its homepage lists 30+ native signals, including job changes, contact-level intent, website visits, M&A and hiring, plus a research agent for custom signals. Reps see the signals in Salesforce, HubSpot, Outreach, Salesloft and Gong Engage (checked November 2026).

• LinkedIn Sales Navigator. Lead and account alerts tell you when a saved lead has an update such as a job or role change, per its product page (checked November 2026).

Why it scores high. A past champion at a new company, or a company hiring the role you support, is a clear reason to write.

Where it falls short. A change tells you the situation moved, not that the person cares about your problem. Many sellers watch the same public triggers, so your opener can sound like theirs.

Where these fit better than traxy. UserGems fits better if you want job changes, hiring and other signals scored against your own sales history and shown inside Salesforce or HubSpot. traxy does not run a live job-change or hiring feed. In a traxy campaign, research on each lead can check for an open role or a recent move before the message is prepared. See hiring signals in outbound and job change signals in outbound.

When is funding data the best source?

Crunchbase tracks private company events such as funding rounds, leadership hires and product launches, and offers funding predictions. Its homepage pitches revenue teams on anticipating funding and growth and reaching high-fit accounts early (checked November 2026).

Why it scores high. A new round can bring new priorities, new hires and a reason to review tools.

Where it falls short. It is a company-level signal, and it doesn't say which problem the money goes to. "Congrats on the round" is a weak opener with nothing else behind it.

Where it fits better than traxy. Teams whose offer is tied to company stage, and who want a funding database to browse and filter, should use Crunchbase. In traxy, funding can be part of your company criteria, and campaign research can check each lead's company for a recent round.

When are bought lists and databases the best source?

Contact databases sell coverage:

• Apollo lists 240M+ contacts and 30M+ accounts, buying signals such as intent, job changes and website visits, and a workspace for prospecting, outreach and dialing.

• ZoomInfo describes verified data on 500M+ contacts and 100M+ companies, with firmographic, technographic and intent data built from public web sources, company websites, filings, job postings and a contributory network.

• LinkedIn Sales Navigator searches 1+ billion members with 50+ filters, such as function, seniority and years at company.

All three were checked November 2026.

Why teams use them. Reach. You can find almost anyone by title, company size and industry, and get an email or a phone number.

Where they fall short. A filter match shows fit, not interest. Two traxy customers moved off Sales Navigator title and keyword lists. Paper Run went from 3 to 5 meetings every 60 days to 16 in the next 60 days. Federico Waldman of Resorsi said of his old keyword lists, "Before, 50% of my leads were garbage."

Where these fit better than traxy. Large-scale coverage of a known market, phone-heavy outbound, buyers who rarely use LinkedIn, and filling in contacts at accounts you already chose. traxy can look up a work email and phone for the leads you keep, but it is not a contact database you browse. See what contact enrichment is. If you want to stop buying lists, alternatives to buying lead lists covers seven replacements and a four-week plan to switch.

What's the best lead source for LinkedIn outbound?

The best lead source for LinkedIn outbound is people who recently showed social intent on LinkedIn and fit your ICP. They posted, commented on or liked posts about the problem you solve, viewed your profile, or engaged with a competitor or a creator your buyers follow.

Three reasons:

1. They are on LinkedIn. People who post and comment there see your connection request and your message.

2. You have a true first line. The post, the comment or the topic gives you something specific to say.

3. You can group them. People with the same signal get a message written for that signal.

The difference shows up in acceptance and reply rates. Teams that switch to traxy leads from other sources usually see LinkedIn reply and acceptance rates about double:

• Platter: reply rate from about 20% to 41%, and connection acceptance from about 20 to 25% up to 50%.

• More Conversions: connection acceptance from 2% to 18%.

• Resorsi: connection acceptance up 54%, and 50% fewer unqualified leads.

• In a test Ben Buaron posted, the same message got 12.6 replies per 100 leads on a traxy-sourced campaign, against 3.6 to 4.55 on three Sales Navigator campaigns. The campaign owner isn't named.

Those are the numbers each team reported. Your results depend on your market, offer and message.

When another source wins. If your buyers rarely use LinkedIn, start from a database and a trigger and lean on email. If you sell to a fixed list of enterprise accounts, use intent data to rank the accounts, then LinkedIn social intent to find the people at them who are talking about the problem.

Why does traxy put social intent and outreach in one tool?

traxy runs your entire LinkedIn GTM end to end, from finding high intent leads from social intent to enriching and researching each one, to running relevant, personalized LinkedIn and email outreach to them on autopilot. The campaign runs on its own after you approve it, or you approve every message.

Most stacks split the source from the send. One tool finds the signal, a spreadsheet or CRM holds it, a data tool enriches it, and a sequencer sends a message that no longer shows why the lead was picked. Each handoff drops context. In traxy, the signal stays on the lead from the first match to the last message:

1. Social intent. Posts, comments and likes on your topics, profile views, Tracking of competitors, creators, company pages and single posts, and social intent search.

2. Qualify. Only 50%+ ICP matches become leads, labeled Warm, Related or Activity, with the source activity shown.

3. Enrich. Work email and phone lookups, and Auto-Enrich for new leads.

4. Campaigns. Organize leads by signal, audience or offer, and run many campaigns at once. Campaigns run in priority order, so one lead never gets two at once.

5. Research on each lead. Each campaign researches the facts you ask for, such as hiring, funding, a job change or anything you describe, filters out who doesn't fit and groups the rest by signal.

6. Sequences. traxy prepares personalized LinkedIn and email steps from that research, sent from your own connected sender accounts.

7. Outreach on autopilot. Test on sample leads with nothing sent, check the launch review (who joins, who is skipped), then approve the launch and the campaign runs on its own. Or approve every message in a review queue. Replies, unsubscribes and hard bounces stop the sequence, and conversations land in one inbox (review and launch).

You can run it by hand in the app, through trax (the traxy agent), or from Claude, ChatGPT, Codex, Cursor or Grok with the traxy MCP, which waits for your yes before anything sends. The outreach side is on the LinkedIn outbound page, and the full model is on the signal-based outbound page.

How does traxy research each lead and run the outreach?

A traxy campaign looks up the facts you ask for on each lead, prepares LinkedIn and email steps from what it finds, and sends them from your own connected LinkedIn accounts and mailboxes. Nothing sends until you approve the launch; after that the campaign runs on autopilot, or you approve each message in the review queue.

Here is what happens between the signal and the reply, beyond the steps above:

• Research fills in what the post can’t tell you. You tell the campaign what to check, such as whether the company is hiring SDRs or uses a tool you replace. Adam Salmanov describes researching each lead from a client’s content engagement for signals like an “Ecom brand doing over 100k site visits & running 50+ meta ads” (Adam’s post). A research-only campaign records what it finds without sending anything, so you can check a new source before you write to anyone (create a campaign).

• Steps wait for the right event. A wait in a sequence can depend on an event such as connection acceptance, so you can hold the first LinkedIn message until the person accepts and add email steps after it (sequences).

• Your accounts, your limits. Sending needs connected sender accounts. Each one keeps its own limits, active hours and ramp-up, a campaign does not bypass them, and emails include your signature when you set one (sender accounts).

• Some people are never contacted. Add emails or LinkedIn profiles to Do not contact and traxy stops outreach to them. The launch review also shows why someone is skipped: another campaign holds them, or they were contacted before.

• You can take over at any point. Each lead has one conversation across LinkedIn and email in the inbox, where you can reply, or pause that lead’s sequence and write yourself (the inbox guide).

The outreach side, with examples, is on the LinkedIn outbound page, and how to follow up on post engagement with a LinkedIn and email sequence walks through one sequence step by step.

How do you build a high intent lead source for LinkedIn outbound?

1. Describe your best customers. Write down the roles, company size, industry and keywords they share, and save them as Lead criteria. Or enter your website and traxy drafts the criteria and signals for you to fix.

2. Name the signals. In Signals, describe the problems, topics and situations that make someone relevant. Turn on the Profile views switch in the LinkedIn activity card if you want profile viewers to become leads.

3. Track who your buyers watch. Add competitors, creators, teammates and investors as tracked profiles, plus company pages by domain and single posts by URL. See who to track on LinkedIn for leads.

4. Search for a first list. Ask social intent search in plain English, for example "founders in the US looking for help with LinkedIn outbound."

5. Check fit and evidence. Open ten leads, read the post or comment behind each, and mark weak matches Bad fit with a reason.

6. Add a trigger where it helps. In the campaign, ask research to check each lead for an open role, a recent round or a job change (create a campaign).

7. Launch one campaign per signal. Test it on sample leads (nothing is sent), check the launch review, then approve.

8. Compare with your current list. Send the same message to your old list and the new one, and compare acceptance, replies and meetings. See test the list before you rewrite the copy.

How do you measure which lead source works best?

Judge each source by cost per qualified opportunity: what the source and the outreach to it cost you, divided by the qualified opportunities it produced in the same period. Lead counts, likes and fit scores don’t settle it, because engagement and a high ICP match do not prove anyone will buy.

What engagement and the fit score tell you. A comment or a like says the person paid attention to the problem. The ICP match says how closely they fit the customer you described. Neither one is a decision to buy: together they tell you who to contact first, not who will sign. See ICP match score vs signal strength.

How to work it out.

1. Define a qualified opportunity first. Agree on it before the test, for example a meeting with someone in your ICP who has the problem and a reason to act.

2. Tag every lead with its source. The list, the search, the tracked profile or the post it came from.

3. Add up the cost of each source. The tool or data for the period, plus the hours your team spends finding, checking and writing to those leads.

4. Divide by qualified opportunities. Count them per source over the same period and divide the cost by the count.

5. Rank sources on that number. A cheap list with no opportunities is the most expensive source you have, and a source with a higher price per lead can still cost less per opportunity.

How traxy helps you count. Each tracked profile and post shows the leads it surfaced and their ICP match, and Insights shows the top profiles or posts bringing in leads. Connect Google Calendar and traxy lists the meetings matched to traxy leads, and you record each outcome as Active opportunity, Already a client or Closed won (how to track meetings booked from LinkedIn outreach). Mark leads Bad fit with a reason to record why they don’t fit. traxy doesn’t know what your other sources cost, so keep that part in your own sheet.

Ben Buaron’s agency runs this as a weekly loop: every Monday it pulls who liked and commented on each client’s posts, filters for ICP fit, tags which post each lead came from, routes each lead to the campaign built for that signal, and puts the booked calls next to the posts that produced them (Ben’s post). Andy Cloyd, co-founder and CEO of Superfiliate, makes the case for counting quality over volume: “A busy calendar is nothing if it’s all low quality. With traxy, the confidence that a meeting is going to be a good meeting is higher, because so much of that qualification work was the input of the signal traxy flagged for us.”

What does this look like in practice?

Paper Run: from title lists to industry engagement. Paper Run ran LinkedIn outbound off Sales Navigator title filters. With traxy, it watches competitors, industry voices and its own content, scores everyone who engages against its ICP, enriches the matches, and every opener refers to something the prospect did. It booked 16 meetings in 60 days, up from 3 to 5, with connection acceptance up 104% and replies nearly doubled (case study).

traxy's own outbound: only warm ICP fits. Over four weeks, Adam Salmanov's team sent 9,930 connection requests across traxy's own and client campaigns, only to ICP fits who had liked a post about the problem or engaged with traxy's posts. 39.3% accepted, 603 replied and 251 were interested. The signal picked the template: someone hiring for a specific role got one message, and someone who had posted 2+ times in 30 days got another (Adam's post with the dashboard).

Profile viewers into a campaign. Ben Buaron's workflow: see who viewed your LinkedIn profile, filter to the people who match your ICP, and sequence them into a signal-based outbound campaign (Ben's post). The step-by-step version is in how to turn profile views into leads.

Which source should you start with?

FAQ

What is a high intent B2B lead?

A person who fits your ICP and recently did something related to the problem you solve, such as commenting on a post about it, viewing your pricing page or comparing vendors. Fit without an action is a target, not a high intent lead. An action from someone outside your ICP is noise.

Is intent data the same as social intent?

No. Third-party intent data, such as Bombora's, mostly reports which accounts are researching a topic. Social intent is what named people post, comment on and like on LinkedIn, so you can see the person and their words.

Are bought lead lists worth it?

They are worth it for coverage, contact details and markets where buyers are not active online. On their own they are a weak source of intent, because a title match shows fit, not interest. Add a signal before you decide who to contact first.

Can you combine lead sources?

Yes, and most teams should. A common order: intent data or funding picks the accounts, LinkedIn social intent picks the people, and research adds the trigger for the message. In traxy, campaign research can add hiring, funding or job change facts to leads found from LinkedIn activity.

Does traxy identify website visitors?

No. traxy reads LinkedIn activity: posts, comments and likes on your topics, who views your LinkedIn profile, people who engage with the profiles, posts and company pages you track, and social intent search. For site traffic, use a visitor identification tool.

Does traxy send the outreach, or only find the leads?

Both. traxy runs LinkedIn and email sequences from your own connected sender accounts. You test on sample leads with nothing sent, review the launch and approve it, then the campaign runs on its own, or you approve every message. Leads can also go to Clay, Zapier, n8n, Slack or a webhook.

Can I run this from Claude or ChatGPT?

Yes. With the traxy MCP you can search social intent, list and research leads, and draft, test and launch campaigns from Claude, ChatGPT, Codex, Cursor or Grok. The AI asks for your yes before anything sends or launches.

Which lead source has the highest intent?

Inbound requests on your website and product, then referrals, because the person asked you or was sent to you by someone they trust. You can’t make more of either when you need leads. Of the sources you can go out and find, public LinkedIn activity ranks highest, because it names the person and shows the post or comment behind them.

Does a high ICP match or a LinkedIn comment mean someone will buy?

No. A comment, a like or a profile view shows attention to the problem, and the ICP match shows fit. Neither proves a purchase. Use them to decide who to contact first, and judge the source by the qualified opportunities it produces.

What is cost per qualified opportunity?

The cost of a lead source, including the tools, data and team time spent working it, divided by the qualified opportunities it produced in the same period. It is a fairer way to compare sources than cost per lead, because a cheap lead that never turns into an opportunity is not cheap.
