What the hiring manager dreads

Unclear budget ownership

Define who controls £/year, ad account structure, and spend guardrails so decisions are measurable.

ROAS volatility and weak attribution

Fix tracking, reduce reporting lag, and stabilise KPIs (ROAS, CPA, CVR) using GA4 and Tag Manager.

Hooks that work

1Experienced
Traffic Manager (e-commerce) managing a £500K/year media plan across Google Ads and Meta Ads.

Optimised audience signals in Meta Ads and keyword intent in Google Ads to improve conversion rate and reduce wasted spend.

Quantified results, clear channel ownership, and the exact stack recruiters look for.

2Junior (progress-ready)
Traffic Manager with 12 months’ experience coordinating campaigns in Google Ads and Meta Ads under defined test-and-learn budgets (£50K/year). Built weekly reporting in GA4, supported event tagging in Google Tag Manager, and improved campaign structure using search term analysis and creative performance insights.

Shows progression, hands-on tooling, and measurable reporting discipline.

Linking spend to revenue: how you run the media performance loop

As a Traffic Manager, I don’t treat PPC and social as separate tasks—I treat them as one performance loop that must link spend to revenue. In practice, I set clear ROAS and CPA targets per campaign type, then track delivery and results in Google Ads and Meta Ads against GA4 conversion events.

I use GA4 and Google Tag Manager (GTM) to ensure conversions are correctly attributed, including Purchase or Lead events and any key micro-conversions that explain funnel drop-off. That combination lets me act quickly when metrics drift, using pacing checks, audience overlap review, and search term performance analysis to reduce wasted spend.

To keep performance stable, I define guardrails like max CPA per stage and minimum CVR thresholds, then review reporting at a cadence that matches learning speed. For example, I’ll monitor weekly trends in cost per conversion, impression share, and click-through rate, then decide whether to optimise bids, adjust targeting, or reallocate budget.

In Google Ads, I use campaign structure and negative keyword management to protect intent quality, while in Meta Ads I refine audiences using engagement and retargeting windows. The outcome is a predictable optimisation rhythm backed by measurable KPI movement, not guesswork.

Attribution that stands up to scrutiny: GA4, GTM, and conversion quality

Recruiters often ask about tracking because unreliable attribution leads to poor decisions, and I build for accuracy from day one. I configure and validate GA4 event tracking via GTM, ensuring UTMs are consistent across Google Ads and Meta Ads, and that conversion events fire correctly before optimisation decisions are made.

Where platforms support it, I implement enhanced conversion settings and verify that deduplication logic is behaving as expected, then compare GA4 numbers with platform reporting to identify discrepancies. This is especially important when multiple devices and sessions are involved, because conversion lag can distort early performance readouts.

For technical rigour, I maintain a conversion documentation sheet (event names, triggers, parameters, and QA status) and run periodic QA checks using GTM preview mode plus GA4 DebugView. I also segment reporting by new vs returning users and landing page cohorts to spot whether traffic quality is improving or deteriorating.

When attribution is ambiguous, I use controlled experiments—like landing page swaps or creative testing—so changes map to KPI shifts rather than noise. This approach helps protect ROAS and keeps optimisation grounded in data the team can trust.

A practical optimisation plan: keywords, audiences, and creative learning cycles

I optimise with a structured backlog so improvements are continuous and explainable to stakeholders. On the Google Ads side, I refine keyword coverage by expanding high-intent terms, tightening with match-type choices, and enforcing a disciplined negative keyword routine based on search terms.

I also review ad relevance using query-to-ad alignment, then link landing page messaging to expected intent to improve CVR. On the Meta Ads side, I segment audiences by intent proxies—such as website visitors, engagement actions, and lookalikes where applicable—and I rotate creatives based on performance signals like CPM efficiency and cost per landing page view.

My approach to learning is to isolate variables where possible and run short, focused tests rather than broad, unfocused changes. For instance, I’ll test two audience hypotheses (prospecting vs retargeting depth) while holding budget and landing pages constant, then follow with a creative test to reduce fatigue.

I track each test outcome against KPI movement—CPA, ROAS, and conversion rate—rather than vanity metrics like impressions alone. Using Google Ads experiments and internal testing logs, I can explain not only what changed, but why it worked and what we’ll do next.

Stakeholder-ready reporting: making performance obvious to non-technical teams

I tailor reporting to the audience, but I always include the same core evidence: spend, conversions, revenue or leads, and the metrics used to make decisions. In weekly dashboards, I map platform results to GA4 outcomes so stakeholders see a consistent story, including what moved ROAS/CPA and which levers drove the change.

I present insights using clear summaries and next-step recommendations, such as “reallocate 15% budget to campaign X after CPA improved by 12%” or “pause ad set Y due to CPM rising without conversion uplift.” Tools like Google Sheets for analysis and Looker Studio for stakeholder views help keep reporting transparent and repeatable.

I also communicate risks early, especially when tracking changes or platform learning phases may affect delivery. If conversion volume is low, I adjust decision thresholds, extend learning windows, and report confidence levels alongside KPI movement.

For teams operating across multiple brands or geographies, I ensure UTMs and naming conventions are consistent so reporting remains comparable. That discipline reduces friction with marketing, ecommerce, and analytics teams while protecting the integrity of the traffic strategy.
