What Is Surge Score?
A metric that flags when an account's research activity on a topic spikes above its baseline.
A surge score measures the degree to which an account's research activity on a specific topic has increased compared to its historical baseline. When the score crosses a threshold, it signals that the account may be entering an active buying cycle. ABM teams use surge scores to time their outreach and campaign activation.
The concept is straightforward. Every company has a normal level of content consumption around topics related to their business. A marketing technology company will always show some research activity around terms like "marketing automation" or "ABM." A surge score only fires when that activity increases meaningfully above the baseline, indicating a change in behavior rather than business as usual.
Most intent data providers calculate surge scores differently. Bombora uses a topic-level model that compares an account's current week of research against its trailing average. 6sense builds composite scores that blend multiple topic surges with other behavioral signals. The methodology matters because it affects how sensitive the score is and how many false positives it generates.
In practice, ABM teams use surge scores in several ways. High surge scores can trigger automated ad campaigns targeting the account. They can alert sales reps to prioritize outreach. They can move accounts into higher tiers for more personalized treatment. Some teams use surge scores as qualification criteria for one-to-one ABM programs.
The biggest pitfall with surge scores is over-reliance. A high surge score does not guarantee an account is ready to buy. The research could be educational. It could be driven by a junior employee with no purchasing authority. It could reflect a content marketing initiative rather than a buying decision. Smart teams use surge scores as timing signals, not as standalone qualification criteria.
Combine surge scores with ICP fit and first-party engagement for the most accurate picture. An account that matches your ICP, shows a high surge score, and is engaging with your own content is a much stronger signal than a surge score alone.
Surge Score in Practice
An ABM team buys Bombora intent data and operates the surge-score concept as their primary intent-trigger logic. A surge score above 70 on a relevant topic (their Bombora topic list includes 12 topics tied to their product category) means the account is showing meaningfully elevated research activity compared to its own baseline. Surge level 3 (the highest) accounts get same-week SDR outreach. Surge level 2 gets next-week outreach. Surge level 1 sits in nurture until it escalates. The team finds surge-triggered outreach converts to meetings at 19% versus 4% for non-surge outbound. Another example: a security vendor pairs Bombora surge scores with 6sense in-platform intent scores and looks for accounts surging on multiple sources at once. A double surge (Bombora high plus 6sense high) converts to opportunity at 31%; either alone converts at 9% to 12%. The team weights double-surge alerts higher and routes them to AEs directly rather than through SDR triage.
The Most Common Mistake Teams Make
Treating any surge as ready-to-buy intent. Surge means an account is researching more than its baseline. That could be a buying signal, or it could be a competitive review, a strategic planning exercise, or noise. Strong programs combine surge with firmographic fit and first-party signals before alerting sales. The other failure is acting only on the highest surge level (level 3 in Bombora's scoring) and ignoring level 2 surges, which can be earlier-stage signals that convert with the right outreach.
What to Measure
Surge-to-meeting and surge-to-opportunity conversion rates, segmented by surge level and topic. Level 3 surges should convert to meeting at 15% to 25% with the right follow-up. Level 1 and 2 surges show lower rates but still beat baseline cold rates if paired with quality outreach. Track conversion by topic too; some topics are stronger predictors of buying than others.
Tool Landscape
Bombora is the most-used surge score provider in B2B. 6sense and Demandbase bundle proprietary surge or intent scoring with their ABM platforms. G2 Intent and TrustRadius offer review-site surge data. ZoomInfo and Cognism include intent and surge in their broader platforms. Most teams subscribe to at least one third-party intent source and overlay it with first-party engagement.
Frequently Asked Questions
What is a good surge score?
It depends on the provider. Most intent platforms use relative scoring that compares current activity to baseline. A meaningful surge is typically 2x to 3x above normal levels. The threshold depends on your conversion data and how many false positives you can tolerate.
How should ABM teams use surge scores?
Use surge scores to time outreach and campaign activation. High surges can trigger ad campaigns, alert sales reps, or escalate accounts to higher ABM tiers. Always combine surge data with ICP fit and first-party engagement for accuracy.
Do surge scores predict purchases?
Surge scores are correlated with buying activity but do not predict purchases with certainty. They indicate increased research, which may or may not lead to a buying decision. Treat them as one signal among many.
What does Bombora's surge score measure under the hood?
Bombora measures content consumption across their cooperative network of B2B publishers. A surge score reflects how much above-baseline an account is consuming content on a given topic in a defined window. Higher surges mean more pages, more articles, or more videos consumed on the topic versus the account's own historical average.
How does surge differ from generic intent data?
Surge is a specific implementation of intent data: it measures change versus baseline rather than absolute levels. An account that always researches a topic at moderate levels won't surge; one that suddenly spikes will. The surge framing catches buying-cycle starts that absolute-level intent might miss.
Should surge data drive outbound or marketing campaigns?
Both. Surge alerts drive timely outbound sequences. Aggregate surge patterns inform campaign timing and air cover. The same data serves different decisions at different cadences.
