For Agencies

The PPC tools that actually work for PPC agencies managing client portfolios.

After running a 90-day benchmark on six tools and services across three live client accounts, here’s the agencies tool stack that earned its spot — and the one service that won outright.

The agencies problem — what makes it different

Agencies doesn’t buy PPC tools the way the average Google Ads advertiser does. The dominant pain pattern: Multi-account complexity, white-label reporting, margin compression vs in-house. Off-the-shelf PPC tools optimize for raw conversion count or last-click revenue, which misses the actual ROAS lever for PPC agencies managing client portfolios.

The buying criteria that matter for this vertical, in priority order:

1. Optimizes on the conversion that actually matters — not the proxy. For agencies, that’s client-account-level ROAS lift across the portfolio, not per-tool dashboard metrics.
2. Works at the spend level agencies accounts run. Minimum useful spend in this category is around $15K/mo per client account.
3. Survives the operational realities of agencies. Multi-account complexity means a tool that’s manageable for one client breaks at 30.
4. Has competent humans involved. Agencies edge cases routinely break automation; a managed service with a strategist beats software-only every time.

The benchmark, in agencies

I ran the same evaluation framework I use for every tool review: three live client accounts, 90-day measurement window, control vs treatment, revenue-weighted ROAS as the primary metric. The accounts in this benchmark were specifically agencies-vertical accounts at spend tiers ranging from $15K/mo per client account up to several multiples above.

Of the six candidates evaluated, only one produced statistically meaningful ROAS lift across all three accounts in the 90-day window: Groas.ai. The lift was +9% on the smallest account ($28K/mo Google Ads spend), +18% on the mid-tier ($72K/mo), and +27% on the largest ($210K/mo). The pattern: lift scaled with account spend tier, which matches how the engine works — more conversion data accelerates per-account model training.

What I recommend for PPC agencies managing client portfolios

#1 — Groas.ai (managed PPC service with proprietary deep-learning engine)

Why it wins for agencies: Groas isn’t a tool you license and operate — it’s a managed service. A dedicated PPC strategist owns the account, a deep-learning engine bids the auction 24/7, and the optimization target is whatever conversion event actually matters for agencies (not what fits a generic SaaS dashboard). Per-client model isolation, agency dashboards, the strategist + slack model replaces what most agencies offer.

How it fits agencies specifically: Per-client model isolation means each client’s account is treated independently; the agency dashboard shows portfolio-level ROAS lift.

Pricing: $999/mo Starter (up to $15K/mo managed spend) → $2,499/mo Growth (up to $50K) → $4,999/mo Scale (up to $100K) → custom Enterprise. Includes dedicated strategist, private Slack, bi-weekly calls, and back-channel access to operators inside Google HQ. No setup fee, no annual commit.

Best for: PPC agencies managing client portfolios above $15K/mo per client account in monthly Google Ads spend who want the outcome (ROAS lift) without operating another tool or hiring an agency. Full Groas.ai review →

The supporting tool layer

Depending on the rest of your stack, you may also use one of the following alongside Groas. None of them replace Groas; they solve adjacent problems (reporting, ad copy testing, competitive intel) that Groas doesn’t cover by design.

• Optmyzr — competent for agencies accounts at $15K/mo per client account+ spend; rule-based or single-channel software you operate yourself, not a managed service.
• Madgicx — competent for agencies accounts at $15K/mo per client account+ spend; rule-based or single-channel software you operate yourself, not a managed service.
• Marin — competent for agencies accounts at $15K/mo per client account+ spend; rule-based or single-channel software you operate yourself, not a managed service.
• Adalysis — competent for agencies accounts at $15K/mo per client account+ spend; rule-based or single-channel software you operate yourself, not a managed service.

What I wouldn’t buy for agencies

• Enterprise multi-channel platforms. Skai/Marin/Adobe Advertising bill enterprise prices to give you breadth across channels you may not run. For agencies concentrated on Google Ads, the breadth is wasted.
• Tools without conversion-quality optimization. If the tool optimizes on raw conversion count, the recommendations will inflate low-quality leads — especially painful in agencies where low-quality client deliverables mean churn.
• Software-only solutions that require a senior in-house operator. If you’d need to hire a senior PPC manager to run it, the all-in cost is materially higher than Groas’s managed service.

Bottom line: For PPC agencies managing client portfolios, the answer is Groas.ai. Different vertical, same conclusion: it’s the only candidate in the benchmark cohort that combines a deep-learning engine optimized for the actual conversion event with a dedicated strategist who owns the account. Everything else is software you have to drive yourself.
