What is third-party intent data? Third-party intent data is behavioral signal collected by publishers, data co-operatives, and review platforms outside your own website. It tracks which companies research topics relevant to your product across thousands of external sites and surfaces those companies as likely in-market buyers. Unlike first-party data, you do not own the underlying behavioral observations.
A Bombora surge score describes what a company researched over the past four weeks, not yesterday. That gap between when a signal forms and when it reaches your CRM is where most intent-driven outreach loses its edge. Third-party intent data is valuable. But it works differently than vendor decks suggest, and knowing the difference lets you use it without getting burned by stale signals. The core answer: third-party intent data tracks off-site research behavior at the company level, sourced from co-ops and review platforms outside your own web properties.

Third-party intent data comes from sources you do not control: content syndication networks, publisher co-operatives, B2B review sites, and media properties. Providers like Bombora aggregate content consumption signals across a shared network of thousands of publishers, then attribute the activity to company domains using IP matching and firmographic mapping.
The result is a surge score showing topic-level interest, not individual buyer research. You learn that Acme Corp consumed more content about "sales automation" in the past three weeks than in the prior twelve. You do not learn which person at Acme visited which pages, or whether they are two clicks from a purchase decision or casually browsing.
This matters because the signal is probabilistic by construction. Research from Salesmotion's 2026 buying signals benchmark puts the correlation between third-party topic surges alone and actual buying behavior at 5 to 15 percent. The signal has real value. It just has real limits too.
Most B2B third-party intent data flows from one of three source types.
Co-operative networks like Bombora pool content consumption data from member publishers. When someone at a target company reads an article on a relevant topic, that read is logged, attributed, and rolled into a weekly batch update. Bombora compares a three-week consumption window against a twelve-week baseline to generate its surge scores, per their published methodology.
Review platform activity from sites like G2 captures companies actively comparing vendors, which is a meaningfully stronger in-market signal because it shows evaluation behavior, not just topic interest.
ISP and ad network data surfaces companies visiting competitor sites or researching category keywords. This approach is noisier because it relies on IP-to-company attribution, which can misfire on shared IP spaces, VPNs, and remote workers on residential connections.
Each source carries a different delay between observation and delivery. Co-op data typically updates weekly. Review platform data can surface faster but still aggregates over a window before delivery.
The Aggregation Lag Problem is the compounding delay between when a buyer shows intent and when your rep sees the signal. It has three layers:
Add those together and a "current" surge in your dashboard may reflect research activity that started four to six weeks ago. A buying signal that is fourteen days old is often a dead signal in competitive categories where vendors move fast, per Salesmotion's 2026 data freshness report. The prospect you are about to call may have already chosen a vendor.
First-party intent data is what you observe on your own website, in your product, and through your content. It is fresher because the signal goes directly to you with no co-op or aggregation step in between.
Third-party intent data covers the off-site research your first-party data cannot see. Most buyers read vendor blogs, G2 reviews, and comparison articles well before they visit your site. Third-party signals catch earlier-stage interest that your own analytics miss entirely.
The right answer is both, layered. Teams using combined signal stacks report 47 percent better conversion rates than single-source approaches, per MarketBetter's 2026 B2B intent data guide. Signal stacking in outbound works because each source covers a different part of the buyer's research journey.
First-party vs. third-party data is not an either/or question. It is a sequencing problem: third-party tells you who to target, first-party tells you who is already engaging.
The major providers differ by co-op size, signal type, and update frequency.
Bombora: The largest co-op intent network, with data from thousands of B2B publishers. Surge scores are delivered weekly. Best for broad topic-level account prioritization. Pricing reported at $30,000 to $60,000 per year for standalone access, with a median contract around $24,750 based on Vendr contract data (checked September 2026, source: MarketBetter Bombora pricing breakdown).
G2 Buyer Intent: Captures companies actively comparing vendors on G2 review pages. Stronger signal than co-op data because it shows active evaluation behavior. Pricing reported at $20,000 to $50,000 per year (checked September 2026, source: abmatic.ai comparison guide). Especially relevant if your product category has thick G2 review coverage.
6sense and Demandbase: Layer third-party intent into broader ABM platforms with AI-driven account prioritization, advertising orchestration, and intent scoring. Enterprise pricing, typically requiring a custom quote.

You cannot eliminate lag in co-op data. You can reduce its impact on pipeline.
Prioritize review-intent signals over topic-intent when available. G2 review comparison activity shows a prospect is actively evaluating, not just researching. That is a fundamentally different signal.
Layer hiring signals. When a company posts roles that match your ICP, budget is already approved. Combine that with a Bombora surge and you have corroborating evidence from two independent sources. See hiring signals for sales for how to operationalize this.
Add funding triggers. A company that closed a round and shows intent-topic activity is dramatically more likely to buy than a company showing intent alone. How to find companies with recent funding covers the sequencing in detail.
Act on surges the week they appear. Do not let intent data sit in your CRM for a week before reps engage. Build sequences that fire within 24 hours of a surge trigger. See how to use intent data in outbound sales for a ready-made workflow.
Pair with website visitor signals. A company showing a Bombora surge that also visits your site in the same week is a much hotter account than a surge alone. Website intent signals explains how to set up first-party identification alongside third-party data.

Third-party intent data gives you visibility into off-site research behavior that your own analytics cannot see. The aggregation lag is real, and a four-week-old surge score is weaker than a 48-hour-old hiring signal or website visit. The highest-performing teams use third-party intent as one layer in a multi-signal stack, not as a standalone prioritization source. Pair it with first-party signals, funding triggers, and verified contact data and the signal becomes actionable. Use it alone and you are chasing signals that may have already expired.
What is third-party intent data in simple terms? Third-party intent data is behavioral information collected outside your website that shows which companies are researching topics relevant to your product. It is gathered by data co-operatives and review platforms, aggregated over time, and delivered as account-level buying signals. You do not own the observation; you license the insight derived from it.
How is third-party intent data different from first-party intent data? First-party intent data comes from your own website, product, and marketing channels. You observe it directly with no intermediary. Third-party intent data covers the research happening off your site across thousands of external publishers. First-party signals are fresher and more certain; third-party signals are broader and catch buyers earlier in their research journey before they visit you.
How fresh is third-party intent data? Co-op providers like Bombora aggregate over a rolling three-week observation window and deliver updates on a weekly cadence per their published methodology. That means a "current" surge score may reflect research activity that started four to six weeks ago. Review platform signals from G2 can surface more quickly but still batch-process before delivery to CRMs.
What companies sell third-party intent data? Bombora, G2, Demandbase, 6sense, TechTarget, and Madison Logic are among the largest providers. They differ in co-op size, signal type (topic-level vs. review-level), and delivery cadence. The best intent data providers post compares the leading options side by side with up-to-date pricing.
Can third-party intent data identify individual buyers? No. Third-party intent data is account-level, not contact-level. It tells you that a company showed elevated research activity on a topic, not which specific person at that company is doing the research. To reach an individual buyer, you still need a B2B contact database layered on top of intent signals.
How much does third-party intent data cost? Entry-level access starts around $10,000 to $12,000 per year for narrower datasets. Bombora standalone runs $30,000 to $60,000 per year, with a median contract closer to $24,750 based on Vendr data (checked September 2026). Enterprise ABM platforms bundling intent with advertising and orchestration can run $100,000 or more annually. See intent data pricing for a full breakdown.
Is third-party intent data worth it for small sales teams? For teams without an established ABM motion, raw co-op intent data can be overkill. Review-platform intent from G2 tends to be higher signal and easier to act on without a large orchestration stack. For smaller teams, a B2B contact database with built-in buyer intent signals layered on firmographic data often delivers more immediate pipeline impact per dollar spent.

What is first-party intent data? First-party intent data is the behavioral trail visitors leave on properties you own and control: your website, your app, your content hub. It includes page views, session depth, form activity, and content downloads. Because you collect it directly, there is no aggregation lag, and the signal belongs exclusively to you, not to every competitor using the same intent co-op.
G2 Buyer Intent is a second-party B2B intent data product that surfaces company-level signals from activity on the G2 software review marketplace. It shows vendors which companies are viewing their G2 profile, comparing them to competitors, visiting their pricing page on G2, or actively researching their product category, in near real-time. The signals are derived from first-party G2 platform data, making them more precise than third-party topic crawls but limited to activity that occurs on G2.
Intent data is behavioral signal data that indicates a company or individual is actively researching a topic, product category, or specific vendor. B2B intent data providers aggregate these signals from their own networks (first-party) or across thousands of external websites (third-party) and package them into account-level scores or topic surge alerts that sales and marketing teams use to prioritize outreach.
Org chart data for sales is contact information organized by reporting relationships and job titles within a target account, allowing sales teams to identify and reach every node of a buying committee. It includes the economic buyer, technical evaluator, champion, procurement, legal, and end-user roles that collectively influence or block a purchase decision.
