Stack
What I work with daily.
I don't like long lists of "data-driven" and buzzwords. This is the concrete stack of tools I use for MUGA clients. Each chosen because it delivers something the rest can't.
Tracking & attribution
The foundation. Without properly configured tracking, optimization becomes an expensive guess.
- Google Tag Manager (Server-Side) — for clean server-side tracking without data loss from ad blockers and ITP
- Stape — GTM Server hosting, cheaper and more performant than GCP direct
- Google Analytics 4 — the only serious web analytics platform
- BigQuery — for custom reporting and attribution on first-party data, not platform-reported numbers
- Conversions API (Meta, TikTok, Reddit) — server-side conversion tracking direct to networks
PPC & ad networks
The 4 networks worth spending your budget on. The rest are on the "What I don't do" list.
- Google Ads — Search, Shopping, Performance Max (only with strict configuration)
- Meta Ads Manager — Facebook + Instagram, with Advantage+ where it makes sense
- TikTok Ads Manager — for clients with video creative that works
- Microsoft Ads — surprisingly effective on US/UK for certain niches
Product feeds (eCommerce)
Most eCommerce campaigns fail at the feed level. Here's what I fix them with.
- Google Merchant Center — source of truth for Shopping and Performance Max
- DataFeedWatch — feed transformation with automated rules
- Channable — DataFeedWatch alternative, sometimes a better fit
- GMC Rules — native rules when no external tool is needed
- Meta Catalog — feeds for DPA and catalog campaigns
SEO & GEO
Classic SEO for Google + GEO (Generative Engine Optimization) for AI search.
- Ahrefs — keyword research, backlinks, content gap analysis
- Screaming Frog — full technical audit on large sites
- Google Search Console — primary data source for SEO
- Schema markup + JSON-LD — structured data for rich results and AI Overviews
- llms.txt — new file format that signals AI engines how to cite your content
Email marketing
For retention and nurture — the channel with the highest ROI per dollar when done correctly.
- Klaviyo — the standard for eCommerce, excellent behavioural segmentation
- Customer.io — for SaaS and clients with long sales cycles
- Postmark — for transactional email with very high deliverability
- Mailchimp — only if the client already uses it and migration isn't the right move yet
Reporting & analytics
The tools through which I show you what's actually happening in your campaigns.
- Looker Studio — client dashboards, custom to each client's needs
- BigQuery + SQL — deep analysis on first-party data
- Hotjar — heatmaps and session recordings for CRO
- Triple Whale — for eCommerce clients who want a single pane of glass
AI marketing & automation
AI for creative ideation, research, reporting automation, GEO and LLM SEO. Never for blind execution or set-and-forget on strategic decisions.
- Claude — for research, audit prep, writing assist, and complex data analysis
- ChatGPT — for creative ideation, campaign brainstorming, ad copy at scale
- Perplexity — for industry research and competitive intelligence with cited sources
- Gemini — for long-context analysis on reports and audits
- llms.txt + structured data — for optimizing your content in AI search
- BigQuery + AI — for anomaly detection and pattern recognition on first-party data
- Custom ML scripts — for predictive bidding and budget allocation
- Automation tools — Make, Zapier, n8n for repeatable workflows
