First-party vs third-party intent data
First-party intent is yours and high-trust; third-party widens coverage. Combined and resolved to accounts, they give the fullest, most actionable picture of who's in-market.
First-party intent data comes from your own properties — website, product, emails. Third-party intent data is collected across the wider web by providers. First-party is higher-trust and lower-volume; third-party widens coverage but is noisier.
First-Party vs Third-Party, line by line
An honest side-by-side — then how to stop choosing and run both.

1st vs 3rd-Party Intent, answered
The questions GTM teams ask most.
What's the difference between first-party and third-party intent data?
+
First-party intent comes from your own properties (site, product, email) and is high-trust. Third-party intent is gathered across the web by providers — broader coverage but noisier and provider-dependent.
Which intent data is more accurate?
+
First-party is generally the most accurate because it's your own behavioral data. Third-party widens coverage to accounts not yet on your site. Combining both, resolved to accounts and filtered by ICP, gives the most reliable picture.
Is third-party intent data worth it?
+
It's valuable for discovering in-market accounts you haven't reached yet, but only when filtered against your ICP and wired to action. On its own it's noisy; combined with first-party intent it becomes far more useful.
How do you combine first- and third-party intent?
+
Resolve both to the account level, score them together against ICP fit, and trigger plays when intent crosses a threshold. A unified score prevents acting on noise and surfaces genuinely in-market accounts.
