Most businesses are missing 20–40% of their conversions in their ad platforms. Blocked cookies, misconfigured tags, double-counting, and missing offline revenue mean every campaign decision is built on incomplete data. We fix that — permanently.

Ad Platforms Covered
Before we build anything new, we audit what's already there. These are the issues we find on almost every account we inherit.
The same purchase fires in GA4, Google Ads, and Meta — making ROAS look 2–3× better than it really is. Most accounts we audit have this.
iOS 14+, Safari ITP, and browser privacy extensions block client-side tags — dropping 20–40% of conversions from ad platform attribution.
Leads convert by phone or get closed in the CRM weeks later — but that revenue never makes it back to the campaign that generated the lead.
GA4 shows 40 conversions. Google Ads shows 71. No one knows which number to trust, so both platforms are optimizing toward fiction.
A GTM trigger condition breaks after a site update. Form submissions stop firing. It goes unnoticed for months. The campaign data is worthless.
The customer first saw the ad on mobile, researched on desktop, and bought on tablet — but the attribution only credits the last click before purchase.
No single method covers every scenario. We deploy the right combination for your traffic, platforms, and business model.
The foundation. Google Tag Manager deployed on your website, firing tracking tags on clicks, form submissions, page views, and custom events. Covers all standard web interactions — fast to deploy, easy to maintain.
A server-side GTM container running in your infrastructure captures events before they reach the browser — bypassing ad blockers, cookie restrictions, and ITP. First-party data that can't be blocked.
When revenue happens offline — a phone call, a CRM-closed deal, an in-store visit — we import that data back to the ad platform via Google Ads Offline Conversions, Meta CAPI, and LinkedIn APIs. Real revenue attributed to real campaigns.
We configure tracking for every interaction that tells you something useful about a visitor — not just the final purchase.
Button clicks, CTA taps, phone number clicks, and navigation patterns.
Full purchase funnel with product-level SKU, price, quantity, and order value.
Lead gen forms, contact forms, quote requests — with field-level detail where needed.
Play rate, watch time, and 25/50/75/100% completion milestones.
PDFs, whitepapers, product specs — any high-intent content interaction.
Logins, signups, trial starts, and subscription changes.
Call tracking numbers with duration thresholds, connected back to campaign source.
25%, 50%, 75%, and 90% page depth — engagement signals for content and landing pages.
Each platform needs its own properly configured conversion signal. We set them all up — and make sure they're consistent, not contradictory.
Event-based tracking with custom conversions, audiences, and data streams. The hub everything feeds into.
Conversion actions, enhanced conversions (hashed email/phone), and offline conversion imports from your CRM.
Pixel implementation plus Conversions API (CAPI) for server-side event deduplication — recovering the conversions iOS privacy settings hide.
Insight Tag, conversion event configuration, and matched audience setup for B2B lead tracking.
UET tag, conversion goals, and remarketing list setup for Microsoft Advertising campaigns.
TikTok Pixel plus Events API for server-side event matching — critical as TikTok's iOS signal loss mirrors Meta's.
We don't just add tags — we audit, plan, build, and validate. Every event is confirmed firing correctly before we hand over.
Review every existing tag, trigger, and variable. Find double-counting, broken fires, and missing events before they corrupt more data.
Map every conversion action to your business goals. Decide what counts as a conversion, what's a micro-event, and what's noise.
Deploy GTM container updates, configure server-side containers where needed, connect platform APIs, and implement offline conversion pipelines.
Real-time validation using GA4 DebugView, GTM Preview mode, and cross-platform reconciliation. We don't go live until every event is confirmed correct.
The difference between tracking set up in 20 minutes and tracking built to stay accurate for 2 years
We confirm every conversion event fires correctly in real-time — not just that the tag appears in the container. If it doesn't fire on the right trigger, we don't sign off.
All implementations follow GDPR, CCPA, and Google's consent mode requirements. Tracking fires only after explicit user consent where required — compliant and still accurate.
We document every tag, trigger, and variable with clear naming conventions. When your site gets updated, your team or ours can quickly identify what needs changing.
We'll audit your current tracking setup, identify what's broken or missing, and show you exactly what we'd build — before you spend a penny. No jargon, no commitment.
Everything you need to know about our Conversion Tracking services
Conversion tracking is the process of measuring and attributing specific user actions on your website — such as purchases, form submissions, button clicks, phone calls, and file downloads — to your marketing channels. Without it, you're spending ad budget blindly, unable to tell which campaigns generate revenue and which waste money. Proper conversion tracking gives you 100% data accuracy so every marketing dollar is accounted for. Extra Large Marketing implements comprehensive tracking through Google Tag Manager (GTM), Google Analytics 4 (GA4), and Google Looker Studio to give you complete visibility into the customer journey from first click to final conversion. For businesses running Google Ads, it's the difference between profitable campaigns and guesswork.
We implement conversion tracking through Google Tag Manager using a structured four-phase process: tracking audit of your current setup, measurement plan aligned with your business KPIs, implementation of tags, triggers, and data layer variables, and finally QA validation. GTM allows us to deploy and manage all tracking codes without touching your website's source code, giving you complete control over data collection. We configure click tracking, e-commerce purchase funnels, form submission events, video engagement metrics, file download tracking, scroll depth measurement, and phone call events — all within GTM's container. Implementation typically takes 1-2 weeks from audit to validated live tracking.
Conversion tracking projects at Extra Large Marketing are custom-scoped based on your tracking complexity, number of events, and platform integrations. Typical implementations involving GTM setup, GA4 property configuration, and core tracking events (clicks, forms, purchases) are completed within 1-2 weeks. We provide a free tracking audit upfront to identify measurement gaps and scope the project accurately — so you know the exact investment before anything begins. Our service covers everything from discovery to live, validated tracking. For clients who also use our Google Ads management service, conversion tracking setup is included in the onboarding process at no additional cost.
Google Tag Manager (GTM) is the delivery system — it manages and deploys tracking tags on your website — while Google Analytics 4 (GA4) is the reporting platform that receives, processes, and visualizes the data those tags collect. GTM handles the 'how' of data collection (triggering tags on clicks, form submissions, page views) and GA4 handles the 'what now' (analyzing user journeys, building audiences, generating insights). Together, they form a complete tracking ecosystem. Extra Large Marketing implements both: we configure GTM as the single container for all your tracking needs, feed that data into GA4's event-based model for analysis, and build Looker Studio dashboards on top for real-time visualization. This stack replaces the fragmented, hard-coded tracking setups that plague most websites.
We implement enhanced e-commerce tracking through GA4 and GTM, capturing the complete purchase funnel: product views, add-to-cart events, checkout progression, transactions, and refunds — all with product-level detail including SKU, category, price, and quantity. This requires proper data layer implementation so that product information flows from your e-commerce platform (Shopify, WooCommerce, Magento, or custom) into GA4 in a structured format. Our implementation achieves 99.9% tracking accuracy, giving you reliable revenue attribution by channel, campaign, and product. Combined with our advanced analytics dashboards, you get real-time visibility into metrics like average order value, conversion rate by device, and top conversion paths — the kind of data that directly informs merchandising and ad spend decisions.
Yes, all conversion tracking implementations by Extra Large Marketing follow GDPR, CCPA, and other global privacy regulations. We configure consent management integration within GTM so that tracking fires only after users provide explicit consent where required. This includes proper cookie consent banner integration, data retention controls in GA4, IP anonymization where applicable, and documentation of all data collection points. Our implementations maintain 100% data accuracy while ensuring full privacy compliance — you get reliable analytics without regulatory risk. For businesses operating across multiple jurisdictions or handling EU customer data, we also configure region-specific consent modes to automatically adjust tracking behavior based on the visitor's location.
Absolutely. Using Google Looker Studio as our central reporting layer, we connect data from Google Ads, Google Analytics 4, Facebook Ads, LinkedIn Ads, CRM platforms, and e-commerce backends into unified, real-time dashboards. This gives you a single source of truth for cross-channel performance — no more switching between five platforms and manually reconciling numbers. Our dashboards include custom KPI tracking, conversion path analysis, device performance breakdowns, and automated reporting delivery. For clients running multi-platform ad strategies, this unified view is often the single highest-ROI analytics investment: it exposes attribution overlaps, identifies the true cost per acquisition by channel, and eliminates the data inconsistencies that lead to poor budget allocation.
Verified reviews from Google Business Profile and Upwork
Closing the loop between ad clicks and real revenue — across different industries and different lead sources.
Playwright + Zapier pipeline to extract revenue and feed offline conversions
Revenue data lived in SingleOps. The API couldn't export it. We built an automation that logged in, pulled the report, cleaned the data, and uploaded real job revenue to Google and Microsoft Ads as offline conversions every morning.
CallRail API + Gravity Forms webhook + headless browser for live chat
A law firm's calls, forms, and live chats lived in three separate tools with no shared data. We piped all three into a single Google Sheet the client manages himself, with automated offline conversion uploads to Google and Bing every morning at 5am.
