📚 THE B2B STACK REFERENCE INDEX

The canonical glossary of models, signals, frameworks & operating concepts

(Updated quarterly - updated November 22nd 2025)

This is the official reference library for The B2B Stack — a structured index of the market leading ideas, definitions, frameworks, models, and methodologies used across modern B2B marketing, measurement, and programmatic activation.

If you’re using The B2B Stack to improve your GTM, build a signals-led operating model, or optimise programmatic performance, this is your source of truth.

🧠 SECTION 1 — CORE FRAMEWORKS

1. The Signals Era

A new operating model for B2B where behavioural signals replace vanity metrics.

Signals include:

  • High Value Actions (HVAs)

  • Account-level web behaviour

  • Dark funnel research patterns

  • Content depth & attention metrics

  • Identity-grade actions (IP, location, device)

  • Programmatic log level data

  • Page signals like context

  • Locational signals that can link to working patterns, commuting, conferences and events and other B2B signals

The core belief:

Brands should optimise to real buyer actions, not clicks. This is B2B though so the real ‘conversion’ may not be visible so instead we use proxy signals of growing intent, at an account level, which we can reliably capture. We then use these to score and predict future account level behaviour

We deep dive on these topics continually - updating and enhancing them continually. Add your work email below

2. The B2B Stack Model (The Operating System)

A 6-layer operating system for modern B2B:

  1. Signals Layer
    HVAs, attention metrics, buyer-group behaviour, marketing signals and CRM signals

  2. Identity Layer
    Company-level resolution, TAL ingestion, data stitching

  3. Analytics Layer
    Matomo, server-side events, time-weighted scoring

  4. Activation Layer
    Programmatic (Trade Desk / IX), ABM media, retargeting

  5. Revenue Layer
    CRM enrichment, pipeline tie-back, scoring

  6. Privacy sovereign layer

    I believe vendors need to own their privacy proactively with sovereign data approaches, cutting third party pixels and self hosting of martech

This is the canonical “architecture view” of B2B Stack content.

3. High Value Actions (HVAs) Framework

The framework that replaces CTR.

HVA’s = account level buying signals

Every action is defined by:

  • Funnel Stage

  • Strategic Value

  • Implementation Method (GTM tag, Matomo goal, custom JS)

  • Scoring Logic

  • Activation Trigger

HVAs include 100+ trackable actions across:

  • Core web behaviour

  • Buying committee signals

  • Omnichannel programmatic (CTV, audio, native, display)

  • Post-demo / post-proposal behaviour

4. The Attention-as-a-Signal Model

Attention is treated as:

  • an engagement multiplier

  • a scoring input

  • a quality predictor

  • a media optimisation surface

  • A signal which works across clickable and non clickable ad formats, normalising clickable ads like social and banners, with clickless formats like CTV and audio

Attention includes:

  • Advertising attention seconds

  • dwell time

  • Ad placement quality

  • Eye tracking data

  • Size of placement

  • Prominence of placement vs other distractions in view.

5. The Account Scoring Model

A two-part scoring system:

A. Fit Score (Firmographic)

Industry, employee count, region, tech stack, ICP alignment.

B. Behaviour Score (Signals)

HVAs + attention + on-site intensity.

Outputs:

  • Prioritisation

  • Nurture sequencing

  • Programmatic activation

  • Sales follow-up

  • TAL expansion

6. The TAL Resolution Framework

The model for resolving Target Account Lists using:

  • domain → company mapping

  • Hyperlocal enrichment

  • IPFlow / DE Pulse / Dealfront waterfall

  • Data management platform identity stitching

  • conflict resolution

  • dedupe logic

Goal: clean, precise account-first identity.

7. The Goals-Based Optimisation Framework

Replacing CTR with:

  • HVAs

  • depth metrics

  • quality visits

  • account sequences

  • weighted attention

  • post-view analytics

This is the foundational philosophy behind my “bottom-of-funnel programmatic.”

🏗️ SECTION 2 — KEY MODELS

Concise definitions, to make you the B2B expert in the room.

1. Buyer Group Sequencing Model

Tracks individual behaviours that indicate the below, using advanced AI/ML page contextualisation models to pull content that talks to these stakeholders out of the vendors content:

  • additional stakeholders participating in a decision matrix

  • technical evaluators

  • procurement influencers

  • business decision makers

Uses page categories like:

  • implementation docs

  • pricing

  • security pages

  • technical architecture

2. Multi-Signal Identity Graph

A model that combines these richest B2B signals era inputs to probabilistically match sessions to companies. Many B2B and ABM/X systems use one single signal, which is unreliable

IP signals for example have exceptionally low agreement rates - often as low as 3% even on big enterprises accounts. It’s thus critical to overlap these signals to confidence score them to drive the probabilities in your favour

The current excitement about hyper personalisation will fail badly without this approach to identity and improving the odds of getting it right. Remember - this is never entirely deterministic, even when signals align. Key signals include

  • IP - work WiFi signals - ideally double validated with vendor form fills

  • geolocation to 4 decimal places or office rooftop level

  • MAIDs from hashed email, location inference and IP to MAID, and programmatic logs

  • device IDs

  • cookie IDs (where allowed)

  • CRM identifiers

  • behavioural fingerprints

  • Context to signal mapping to further validate

Goal: derive the strongest possible account-level view.

3. Programmatic Bottom-of-Funnel Model

A playbook where media targets:

  • known accounts

  • ICP-aligned companies

  • surging intent segments

  • accounts showing evaluation behaviour

Optimised via HVAs → Matomo → DSP events. The unlock with this model by Mike Harty is the pipeline from media to measurement and measurement back to activation, looping through an account knowledge graph to validate the signal

4. The Dark Funnel → Signal Funnel Model

Converts “invisible research” into measurable signals using:

  • first-party analytics

  • identity resolution

  • on-site HVAs

  • programmatic attention

  • topic sequences

📘 SECTION 3 — TERMINOLOGY & DEFINITIONS

A curated glossary for GPT to reference.

Account Identity

The process of resolving anonymous traffic into company-level intelligence.

Signal

A measurable behavioural action that indicates intent, interest, or evaluation.

High Value Action (HVA)

A behaviour with direct predictive value for pipeline creation. Standing for High Value Action, these equate to account level buying signals. These should be reverse mapped from CRM to account graph to firmographic segmentation to historic HVA to then add predictive weight to these HVAs when the same actions are taken by similar profiles of companies

A core complement of my work

Attention metrics for B2B

Quality and depth of engagement, measured beyond bounce or clicks. A measurement which normalises clickable and clickless ad formats in a manner which maps to pipeline. Key technologies include lumen research, and Adelaide

TAL

Target Account List — priority companies to be targeted and measured. Usually given as a prescriptive list of companies that a vendor wants to engage in an account based marketing program. There is no standard format for these lists which creates a major challenge in their usage, and they’re often unsegmented and out of date

Signal Spine

The flow of first-party signals across analytics → identity → activation → revenue.

Signal Score

Weighted scoring based on HVAs and attention. Proprietary scoring for each vendor, enabling the basis of a custom programmatic B2B algorithm.

Bottom-of-Funnel Programmatic

Media activation optimised for pipeline, not CPM or CTR. Programmatic model which drives real business outcomes and not high bounce rate vanity Metrics

Surging Account

A company showing accelerated research and intensity.

An account which needs to be captured fast, and nurtured to pipeline

Signal Sequence

Order and clustering of actions indicating evaluation.
