Paid Search & Shopping

Ad spend that pays for itself, then keeps paying.

Impressions don't pay invoices. We build paid search and shopping campaigns engineered around profitable ROAS — not click volume, not vanity reach.

The Bidding Engine

Where tight account structure meets bidding logic that protects margin, not just market share.

We treat every campaign as a profit centre, not a traffic source. Structure, bids, and budgets are built around unit economics from day one, so spend scales only where it's actually earning a return.

Our philosophy

Good PPC spends less to earn more. Bad PPC just spends more.

Most agencies optimise for clicks, impressions, and conversion volume — numbers that look great in a dashboard and say nothing about whether the business actually made money. We start from your margin and your unit economics, and build campaign structure backwards from there.

That means every keyword we bid on, every audience we target, every dollar we shift between campaigns is driven by one question: is this spend profitable at scale? If it isn't, we cut it — regardless of how good the click-through rate looks.

Profit-first bidding

We bid to target ROAS and CPA ceilings tied to your actual margins, not to maximise impressions or vanity click volume that drains budget.

Structure built for control

Tight, segmented campaign and ad group structure means we can isolate what's working at the keyword level — not guess from blended account averages.

Built to be tested

Every account runs structured ad copy and landing page experiments. Winners get budget; losers get cut — fast, not after a quarter of hoping.

What's included

From account audit to scaled, profitable spend — fully managed.

We don't hand off a campaign and walk away. We build the structure, write the ad copy, manage bids daily, and keep iterating until every dollar of spend is earning its place.

Account Audit & Structure

We tear down your existing account — wasted spend, broken conversion tracking, overlapping keywords, poor Quality Scores — before a single dollar moves. Most accounts we inherit are leaking 20-40% of budget on day one.

Account auditConversion trackingCampaign structure

Keyword & Audience Strategy

We build keyword lists around commercial intent, layer in negative keywords aggressively, and define audience targeting tied to your actual customer profile — not broad-match guesswork that burns budget on irrelevant traffic.

Search intentNegative keywordsAudience targeting

Ad Copy & Creative

Search ad copy, responsive display assets, and shopping feed optimisation built to earn clicks from buyers, not browsers. Every ad is tested against real alternatives, not shipped on a gut feeling.

Bid & Budget Management

Daily bid management and budget reallocation toward what's actually converting profitably. We use automated bidding where it earns its keep, and override it where it doesn't — not a hands-off "set it and forget it" approach.

Smart biddingBudget pacingDaily optimisation

Landing Page & CRO

Paid traffic to a weak landing page is wasted budget. We audit and optimise post-click experience — message match, page speed, form friction — so the clicks you're already paying for actually convert.

Reporting & Attribution

Reporting tied to revenue, margin, and customer lifetime value — not clicks and impressions. Every project includes a 60-day initial optimisation sprint, then ongoing monthly management as the account scales.

How it works

From audit to profitable scale — exactly how we do it.

No black boxes. You know what's being spent, where, and why at every stage of the engagement.

01

Discovery & Account Audit

A full audit of your existing accounts — conversion tracking accuracy, wasted spend, Quality Scores, campaign structure — plus a 90-minute kickoff to understand your margins, target CPA, and growth goals. Deliverable: a written audit and prioritised action plan.

Kickoff workshopAccount auditTracking auditAction plan
02

Strategy & Account Rebuild

We rebuild campaign structure around your margin targets, define keyword and audience strategy, and fix conversion tracking so every dollar reported is a dollar you can trust. Reviewed with you before launch — no surprises once spend goes live.

Campaign structureKeyword strategyTracking setupBudget plan
03

Creative & Landing Page Build

We write and test ad copy variants, build out shopping feed optimisation where relevant, and audit your landing pages for message match and conversion friction before any meaningful budget scales up.

04

Launch & Daily Management

Campaigns go live with tight budget caps while we gather conversion data. From there, bids and budgets are managed daily — shifting spend toward what's converting, cutting what isn't, and protecting against runaway costs.

05

Testing & Scaling

Once core campaigns are profitable, we layer in structured A/B tests on ad copy and landing pages, expand into new keyword segments or platforms, and scale budget behind what's proven — not what's promising.

Report & Compound

Monthly reporting ties spend directly to revenue, margin, and customer acquisition cost — not impressions. We review what's working, cut what isn't, and reinvest savings into the highest-performing segments. Most clients see ROAS continue climbing well past month three as data accumulates.

Two recent engagements — different industries, same discipline. Start with the margin, build the structure, scale only what's proven.

From the people we've built for

Our previous agency reported impressions and click-through rate like those were wins. Digital Zenith showed us we were burning 40% of our budget on searches that never converted. Fixing that alone paid for the engagement in month one.

Marcus Klein

They restructured our entire shopping feed around margin, not just sales volume. We're now spending less overall and making more profit than when we were chasing every sale regardless of what it actually earned us.

Most PPC agencies want to "set and forget" with automated bidding and call it a strategy. Digital Zenith is in the account daily. That's the difference between a managed account and a babysat one.

FAQ

Questions we get asked a lot.

If your question isn't here, book a 30-minute call — no obligation, no pitch deck.

How long before we see results from PPC?

Campaigns can go live within two weeks, and you'll see early conversion data within the first month. Meaningful ROAS improvement typically shows by month two as bidding algorithms gather enough data, with the biggest gains landing by month three as testing and budget reallocation compound. PPC is faster than SEO, but it still rewards patience over panic.

Do you take a percentage of our ad spend as a fee?

No. Percentage-of-spend pricing creates a built-in incentive to spend more of your budget, not to spend it well. We charge a flat monthly management fee scoped to account complexity, so our incentive is the same as yours — better performance, not bigger bills.

Which platforms should we advertise on?

That depends on where your customers are actively searching or browsing with buying intent. Google Search tends to win for high-intent commercial keywords, Shopping for e-commerce with a strong product catalogue, and Meta or TikTok for demand generation and retargeting. We'll recommend a starting mix in the audit and expand based on what's actually converting.

Will you use fully automated bidding?

We use automated bidding strategies where the data supports them, but we don't hand over the account and walk away. Automated bidding without human oversight tends to chase volume over profitability if left unchecked, so we set the guardrails — target ROAS, budget caps — and intervene when the algorithm drifts from your margin targets.

What happens after the initial engagement?

PPC is not a set-it-and-forget-it channel — auctions shift, competitors enter, and creative fatigues over time. After the initial structure and optimisation sprint, most clients move to an ongoing monthly retainer for continued bid management, testing, and budget scaling. This is where ROAS keeps compounding as we learn what works at your specific scale.
