Web Analytics Stack

Which Web Analytics Stack Fits Your Business?

Every MarTech stack depends on accurate measurement. The difference between companies that guess and companies that know is implementation depth. Pick the stack that matches your growth stage.

Tier 1

Foundation

GA4 implementation, GTM setup, basic event tracking, dashboards, attribution baseline

Tier 2

Growth

GA4/GTM audits, attribution fixes, BigQuery export, Consent Mode V2, CRO tracking

Tier 3

Enterprise

Server-side GTM, first-party data routing, BigQuery pipelines, full data ownership

Six tools form the measurement layer of every stack

What changes between Foundation, Growth, and Enterprise is not which tools are used. It is how deeply each tool is configured, validated, and connected to your decisions.

GA4

Web Traffic Analysis

GTM

Tag Management

Search Console

SEO Visibility

Social Attribution

Campaign Tracking

Privacy

Consent & Compliance

Looker Studio

Dashboards & Reporting

E-Commerce tracking: Enhanced e-commerce events, Merchant Center integration, and SKU-level revenue attribution are implemented within the Growth or Enterprise stack based on transaction volume and reporting requirements. E-commerce is a configuration layer added to the right stack, not a separate tier.

Tier 1

Foundation Stack: Tracking Setup

Reliable data collection starts here. No analytics decision is trustworthy without a clean foundation.

Most companies skip straight to dashboards without verifying that GA4 events fire correctly, that GTM containers follow a logical structure, or that attribution paths reflect actual user journeys. The Foundation stack solves this by building measurement infrastructure from the ground up.

  • GA4 property configuration with custom event taxonomy
  • GTM container setup with organized tags, triggers, and variables
  • Core conversion and engagement event tracking
  • Attribution baseline with GA4 default channel groupings
  • Looker Studio dashboards connected to GA4 and Search Console
  • Basic privacy and cookie consent configuration
Foundation Stack Investment From $2,499 + from $750/month ongoing

Saves ~$1,296 vs booking GA4 impl ($1,499) + GTM ($1,299) + Cookie Consent ($997) separately

Problem It Solves

Your GA4 property shows inflated session counts, missing conversions, or zero attribution data. Tags fire out of order or not at all. Dashboards exist but nobody trusts the numbers behind them.

Outcome: Reliable Tracking

Every event fires correctly. Attribution paths reflect real user behavior. Dashboards show validated data your team can act on without second-guessing the source.

Tier 2

Growth Stack: Tracking Accuracy

You have tracking in place. Now make it accurate enough to trust for revenue decisions.

Growth stack includes everything in Foundation, then adds audit-driven accuracy fixes. GA4 and GTM containers get reviewed line by line. Broken conversion paths get rebuilt. BigQuery export captures raw event data before GA4 sampling dilutes it. Consent Mode V2 recovers data that privacy regulations would otherwise block.

  • Everything in Foundation stack
  • Full GA4 property audit with severity-rated findings
  • GTM container audit and consent-aware tag sequencing
  • Conversion path repair and attribution recovery
  • BigQuery raw event export with pre-built analysis queries
  • Consent Mode V2 with CMP integration for GDPR and CCPA
  • CRO event tracking and conversion funnel analysis
  • AEO signal configuration for AI search visibility
Growth Stack Investment From $6,999 + from $2,500/month ongoing

Saves ~$3,091 vs booking Foundation + GA4 Audit ($999) + GTM Audit ($799) + CRO ($2,500) + SEO/AEO ($1,997) separately

Problem It Solves

Conversion counts in GA4 do not match your CRM. Campaign attribution credits the wrong channels. Consent banners block data collection without behavioral modeling to recover it.

Outcome: Decision-Ready Data

Conversion numbers match reality. Attribution reflects actual customer journeys. BigQuery preserves unsampled event data. Your team makes revenue decisions on validated metrics.

Tier 3

Enterprise Stack: Data Infrastructure

Full data ownership. No third-party dependency. Your cloud, your pipeline, your rules.

Enterprise stack includes everything in Growth, then adds server-side infrastructure that moves data collection off the browser and into your own Google Cloud environment. Server-side GTM routes events through your first-party domain, bypassing ad blockers and reducing client-side tag load. BigQuery pipelines run scheduled queries, ML models, and cross-domain joins that GA4 alone cannot perform.

  • Everything in Growth stack
  • Server-side GTM on Google Cloud Run with first-party domain routing
  • Advanced BigQuery pipelines with scheduled queries and Cloud Functions
  • Cross-domain tracking with unified user identity resolution
  • Hit-level data validation and bot filtering frameworks
  • Server-side consent enforcement with consent-routed data flows
  • BigQuery ML for predictive churn scoring and LTV modeling
Enterprise Stack Investment From $22,000 + from $7,500/month ongoing

Enterprise-scoped engagement. Custom quote based on sGTM architecture, data residency requirements, and domain count.

Problem It Solves

Ad blockers remove 15-30% of tracking hits before reaching GA4. Client-side tags create page load delays. Cross-domain user journeys break identity resolution. Your data lives in Google's infrastructure with retention limits you cannot control.

Outcome: Full Data Ownership

Events route through your first-party domain and land in your BigQuery instance. No ad blocker interference, no sampling, no retention limits. You own the pipeline end to end.

How your analytics stack matures

MarTech maturity is not about adding more tools. It is about increasing control over the measurement layer that every other tool depends on.

1

Foundation

Tracking

Clean GA4 implementation, organized GTM container, baseline attribution, and validated dashboards your team can trust as a starting point.

2

Growth

Accuracy

Audit-driven fixes to broken conversion paths, BigQuery export for unsampled data, and Consent Mode V2 to recover attribution from privacy-compliant users.

3

Enterprise

Ownership

Server-side data pipeline on your own Google Cloud infrastructure. No ad blocker interference, no sampling limits, no third-party data dependency.

Built on Google's native stack. No proprietary middleware.

AI-Assisted, Expert-Reviewed

Automation handles configuration speed. Senior engineers handle the logic that tools miss: edge-case tag sequencing, consent flow dependencies, and cross-domain identity stitching. Faster delivery without cutting corners on accuracy.

Faster Than Agency Timelines

Foundation deploys in 2 to 3 weeks. Growth in 4 to 6 weeks. Enterprise in 8 to 12 weeks. Delivery is faster because Waftr specializes in Google-native infrastructure, not full-service marketing retainers.

Deeper Accuracy Than Tools Alone

GA4 default settings miss conversions, misattribute channels, and lose data to consent gaps. Waftr stacks fix the infrastructure layer that tools configure but do not validate.

Cost-Efficient Infrastructure

Every stack uses Google's free and paid tiers appropriately. You pay for what you need. No vendor lock-in, no proprietary platforms sitting between you and your data.
