Google Ads Agency — economically managed, not platform-driven.
Search, Shopping, PMax, and Demand Gen — managed for economic contribution, not for platform recommendations. Calvarius has worked as a Google Ads agency for e-commerce, B2B, and SaaS since 2013 — with our own feed-management tool and clean server-side tracking as a control foundation.
Standpoint
What a Google Ads agency must truly deliver today.
Anyone looking for a Google Ads agency usually has a concrete economic question in mind: will I get the return for my ad budget that the platform promises? The honest answer, after over ten years as a Google Ads agency: not without discipline at the control level. Performance Max takes control away, Smart Bidding hides logic behind algorithms, and account recommendations often serve Google's interests, not the advertiser's. Anyone running Google Ads today like in 2018 is burning money. But anyone who blindly trusts the system and clicks "apply recommendation" loses control over profitability.
Calvarius positions itself between these extremes. We use the machine advantages — automated bidding strategies, PMax as a volume lever, Smart Shopping as an efficiency tool — but we steer them by economic metrics, not platform vanity metrics. Clicks aren't a success metric, conversions aren't a success metric — contribution margin per invested euro is the success metric. This metric isn't default-visible in Google Ads; we make it visible.
Concretely, that means: We build conversion tracking not as a compulsory setup, but as an economic data foundation. We use Enhanced Conversions for higher data quality. We cleanly separate brand and non-brand performance instead of drowning in the account aggregate. We review monthly which campaigns are still running at positive contribution and which aren't — and shut off without sentimentality what doesn't work. Our own feed management through our tool Delta ensures shopping and PMax campaigns work with clean, platform-specifically optimized product data — without Excel ping-pong and without one-size-fits-all feeds.
Audience fit
When you need a Google Ads agency — and when you don't.
Most important performance channel for most e-commerce setups. Search serves demand, Shopping serves comparison, PMax scales. Sensible from ~€5,000/month, fully scalable to six-figure budgets.
Search works for B2B when buying intent maps to searchable language — SaaS, IT, consulting. With long sales cycles, LinkedIn is often the better first channel; Google complements bottom funnel.
Works when trial conversion is cleanly tracked and CAC is clearly defined. Search for branded and bottom funnel, Demand Gen for awareness.
Monthly budget under €2,500 — operational effort exceeds the lever. Expectation 'double my ROAS' — we make no promises. If tracking can't be cleaned up — without clean data, performance is gambling.
Methodology
How our Google Ads agency starts mandates.
- 01Analysis (3–5 days)
Account audit, competitive analysis, tracking audit, feed quality check, customer lifetime value modeling where data is available. Output: concrete hypotheses where money is being left on the table economically — not marketing platitudes. No 80-page audits for self-profiling, but a focused assessment with concrete levers.
- 02Setup & Hardening (1–2 weeks)
Hardening tracking (server-side, Enhanced Conversions, GA4 integration). Aligning account structure to economic logic — brand vs. non-brand, funnel stages, margin classes. Feed optimization via Delta. First bid strategy adjustments. Where technical setup is already clean, this goes faster — where not, here lies the biggest lever.
- 03Scaling (from week 2–3)
Once the tracking foundation is in place: budget expansion in working areas, closure in unprofitable ones. PMax as volume lever with clearly delineated asset groups. Demand Gen for awareness extension where economically viable. Iteration cycles weekly, not monthly.
- 04Ongoing Operations (continuous)
Monthly performance review with economic metrics, not platform metrics. Quarterly strategic adjustments. Operational management typically directly by the managing director — not by junior account managers with heavy mandate loads. Response times typically within one business day.
Fast start as competitive advantage
While classic large agencies often need six to twelve weeks before the first optimized setup goes live, we are productive in the market within two to three weeks. This is possible because we don't manage stakeholder layers but work directly operationally.

What's realistic
Realistic results of a Google Ads optimization.
These ranges are empirical. We make no promises — serious performance management works with the concrete situation, not advertising claims.
- 01
Efficiency improvements of 20–40% in the first year are realistic in most mandates — especially where tracking, account structure, or feed quality were historically neglected.
- 02
Cost-per-acquisition reduction of 15–30% in B2C e-commerce within 3–6 months is a typical range when previously working with unchecked platform recommendations.
- 03
Scaling leverage of 2–5x at the same ROAS is possible when customer economics support it. Scaling without an economic check isn't a service, it's risk.
- 04
Brand-search share reduction of 10–25% at the same revenue is a typical lever when brand and non-brand have historically been mixed.

Glossary — related terms
Definitions and depth on the recurring concepts of this service.
- Smart BiddingSmart Bidding refers to automated bidding strategies in Google Ads that machine-learning-based optimize bids per auction in real-time — in contrast to manual bidding strategies.
- Target CPATarget CPA is a Smart Bidding strategy in Google Ads that controls bids so that conversions on average occur at a defined cost-per-action target value.
- Target ROASTarget ROAS is a Smart Bidding strategy in Google Ads that controls bids so that a defined Return on Ad Spend target value is achieved — relevant primarily for e-commerce setups with different conversion values.
- Performance MaxPerformance Max is Google's campaign type introduced in 2021 that automatically delivers a single campaign across all Google inventories — Search, Display, YouTube, Discover, Gmail, Maps.
- Quality ScoreQuality Score is Google's evaluation of the quality of a Google Ads ad on a scale of 1 to 10. Three factors feed in: expected click-through rate (CTR), ad relevance to the search term, landing page user-friendliness. Economic relevance: higher Quality Score lowers the effective CPC and improves ad rank — a Quality Score 9 account often pays 50 percent less per click than a Quality Score 5 account in the same auction. Levers for improvement: precise keyword-ad-landing-page congruence, clear conversion paths, fast loading times. Not directly visible in Performance Max campaigns.
- Budget PacingBudget pacing is the temporal distribution logic by which ad platforms like Google Ads spend the configured budget over a period — either evenly (standard pacing) or accelerated.
