Summarize this article with:
We audit Google Ads accounts every week, which means we also see the aftermath of every kind of agency relationship: the good, the lazy and the quietly expensive. The pattern is consistent. Businesses rarely pick a bad agency because they ignored red flags. They pick badly because they compared pitches instead of comparing systems, and every pitch sounds identical. The fix is to score agencies on twelve weighted criteria before you ever discuss price, because the agency that survives a scorecard is almost never the one with the best pitch. This guide gives you the exact scorecard we use, the five questions that expose weak agencies in one call, and the honest math on agency versus in-house versus freelancer.
- Score every candidate on the 12-point weighted scorecard below; under 70 out of 100 is a pass.
- Measurement capability and account ownership matter more than case studies.
- Five questions, asked in the first call, filter out 80% of weak agencies.
- Fee models are negotiable; data ownership never should be.
Score the work, not the pitch. Ask how they audit GA4 and conversion tracking in week one, how they steer Performance Max rather than trusting it, how often they review search terms and update negative keyword lists, and how they diagnose Quality Score problems rather than simply quoting the number back at you. If Performance Max carries most of your spend, our ranking of the best Performance Max agencies for 2027 applies the same checks to PMax. Then ask for accounts that look like yours. If you are hiring in Australia, our Sydney Google Ads agency comparison adds the AEST, AUD fee and contract questions to ask. In Queensland, our Brisbane Google Ads agency picks add a 10-point account health check and council-level targeting. In South Australia, our Google Ads agency Adelaide guide checks each provider’s location and Google Partner status. In the ACT, our comparison of Google Ads companies in Canberra adds ACT-only public holidays and the November 2025 procurement threshold. Ours include a local signage company taken from 1.5x to 7.35x ROAS, a commercial cleaning equipment supplier that saw 5.3x more leads at a 73% lower cost per lead, and ArmorPoxy at $1.58M and 12.84x ROAS.
Start With the Only Question That Matters
Before criteria, get clear on what you are actually buying. You are not buying campaign management. You are buying a decision system: someone who decides where your next dollar goes, based on data you must be able to trust. That reframing changes the evaluation. Suddenly the certifications wall matters less than whether the agency validates conversion tracking before optimizing, and the client logo slide matters less than who, specifically, will be inside your account on a Tuesday afternoon.
The 12-Point Google Ads Agency Scorecard
Score each candidate 1 to 5 on every row, multiply by the weight, and total. We built this from the criteria that actually predicted success across our own audits of accounts arriving from other agencies.
| # | Criterion | Weight | What a 5 looks like |
|---|---|---|---|
| 1 | Measurement discipline | 15% | Audits tracking before touching bids; explains deduplication and enhanced conversions unprompted |
| 2 | Account ownership | 12% | You own the account, tags, audiences and history; access survives termination, in writing |
| 3 | Relevant proof | 12% | Results in your vertical and budget range, with spend and timeframe shown, not just percentages |
| 4 | Profit orientation | 10% | Talks break-even ROAS, margins and CAC, not clicks and impressions |
| 5 | Who does the work | 10% | Names the actual account manager, their tenure and account load before you ask |
| 6 | Testing roadmap | 8% | Presents a specific first-90-days plan with hypotheses, not “we will optimize” |
| 7 | Fee transparency | 8% | Written rate card, all fees totaled for 90 days, no hidden platform charges |
| 8 | Communication cadence | 7% | Defined reporting rhythm, named response times, direct strategist access |
| 9 | Contract flexibility | 6% | Month to month after a short ramp, no punitive exit clauses |
| 10 | Landing page involvement | 5% | Audits and tests pages, or coordinates tightly with whoever does |
| 11 | AI bidding guardrails | 4% | Explains how they constrain Smart Bidding and catch algorithm drift |
| 12 | Honest disqualification | 3% | Willing to say your budget or offer is not ready, and what to fix first |
Two scoring notes from experience. Treat criterion one as a gate, not a tradeoff: an agency scoring below 4 on measurement cannot compensate with anything else, because every other decision inherits its data. And weight criterion twelve seriously despite its small number, since the agency willing to turn down your money today is the one you can trust with it tomorrow.
Five Questions That Expose Weak Agencies in One Call
First: “Walk me through the last tracking problem you found on a new account and how you fixed it.” Strong agencies answer with specifics in seconds. Second: “If we leave in six months, what exactly do we keep?” The only acceptable answer is everything. Our guide to outsourcing PPC lists what everything means: the accounts, billing, conversion actions, audiences and change history. Third: “Who will work on our account, how many accounts do they manage, and can we meet them before signing?” Fourth: “What would you test in the first 90 days, and why those tests first?” Fifth: “What would make you tell us to spend less?” That last one is the killer. An agency paid on percentage of spend that has never recommended a spend cut is describing its incentive structure, not your growth plan.
Every agency sounds data-driven in a pitch. The scorecard exists because pitches are marketing, and marketing is the one thing every agency is good at.

One question worth adding: what does your Conversions column actually count? Our case study on what a Conversions column counts shows how far reported conversions and completed applications can drift apart.
Should You Hire an Agency, a Freelancer or Build In-House?
Under roughly $1,000 in monthly ad spend, hire nobody: run it yourself against our audit checklist until the offer proves itself. Between $1,000 and $5,000, a specialist agency with flat entry pricing or a vetted senior freelancer both work; the agency buys you process and backup, the freelancer buys you attention, and either should cost $600 to $1,500 per month. From $5,000 to $50,000, agencies generally win on tooling and coverage. Past $50,000, compare a senior in-house hire plus tools (realistically $90,000+ per year fully loaded) against a 10% to 12% agency fee, and consider the hybrid most scaled brands land on: in-house ownership of strategy and data, agency execution of the channels. Whatever you choose, model the fee against required return with our ROMI calculator before signing. If a freelance consultant is still in the running, read PPC consultant vs PPC agency for a side by side breakdown, and if a solo specialist suits you better, compare these top Google Ads consultants. Hiring in Australia? Our ranking of Google Ads agencies in Melbourne applies the same tests with local checks such as GST, AUD reporting and daylight saving schedules. Hiring in India? Our guide to the best Google Ads agency in India adds GST invoice, rupee fee and Google Partners directory checks.
The Red Flags We See Most in Rescued Accounts
Accounts arrive at us from other agencies with the same wounds, so learn the pattern. Agency-owned ad accounts that vanish at termination. Reporting that celebrates ROAS while contribution margin quietly bleeds. One shared login and no named strategist. The bait and switch, where the senior strategist who ran the sales call hands your account to a junior the week after signing. Reporting that lives only in the agency’s own dashboard while you hold no admin access to your own Google Ads account. Guarantees of specific rankings or ROAS made before anyone looked at your data. Setup fees above $1,500 for standard builds. And the subtlest one: performance recaps that never once mention a failed test, because an agency that never fails is an agency that never tests.
The Mistake That Rewrote Our Own Onboarding
The scorecard’s heaviest weighting exists because we once got it wrong ourselves. Early on, we took over an account and, eager to show quick wins, spent the first two weeks restructuring campaigns before fully validating the conversion setup we had inherited. The restructure looked great against numbers that turned out to be partly duplicated. We caught it, rebuilt the tracking, and re-ran the comparison honestly, but it cost the client weeks of clean learning data and cost us an awkward conversation we never wanted to repeat. Since then, no Hustle Marketers account gets an optimization before its measurement passes audit, and we tell prospects to hold every agency, including us, to that order of operations.
How Do You Switch Your PPC Agency Without Losing Data?
To switch or replace your PPC agency without losing data, change who has access, not which account you advertise from. Keep the same Google Ads account so its history and conversion data stay, give the new agency access before the old one loses it, hand over Merchant Center, GA4 and Tag Manager, and hold off on bid strategy and conversion changes until the new agency has audited tracking.
Most of the damage in an agency switch comes from the order of steps, not the switch itself. Revoke access too early and ads or tracking break. Rebuild too early and campaigns go back into learning on data nobody has checked.
Who should own the Google Ads account when you change agencies?
Your business should own it. The Google Ads account, Merchant Center, GA4 property and Tag Manager container should sit under your company, with your own email holding Admin access, and the agency added as a user or a linked manager account. If you own the accounts, changing agencies is an access change, not a migration.
Google’s access levels help says only Admin users can give account access, accept or reject manager account link requests and unlink manager accounts. It also says that when a manager account has ownership, its admins can edit user access, managers and product links in your account. So before you give notice, check two things in Google Ads under Admin, Access and security: that your own email is an Admin, and which manager accounts are linked.
If the old agency built the account under its own name or holds the only admin login, ask it to add your email as an Admin first. That conversation is easier before you announce the switch.
Why keep the same Google Ads account instead of starting a new one?
Keep the same account because the history lives there. Google says that after an account is unlinked from a manager account, it won’t lose its own account campaign history or access to Google Ads features. A new account starts with no conversion history for Smart Bidding to learn from, no audiences and no record of what has already been tested.
The record of past tests matters too. Google Ads change history covers the past two years and shows which user made each change, so the new agency can see what was tried before it changes anything.
Check where tracking and audiences live before anyone unlinks the old manager account. Google’s unlinking help says remarketing lists built on the manager account’s shared tag stop filling, and a cross-account conversion tag from that manager stops recording conversions for clicks after the unlink. If your conversions or audiences depend on the old agency’s manager account, move them into your own account first.
How do you hand over access to Google Ads, Merchant Center, GA4 and Tag Manager?
Hand over access in this order: confirm your own admin rights, sort billing, add the new agency, check tracking, then remove the old agency last. Each platform has its own user list, so an agency removed from Google Ads can still have access to Merchant Center, GA4 or Tag Manager.
- Confirm your Admin access in Google Ads. Your company email, not a personal or agency email, should be an Admin.
- Check billing before any unlink. Google says that if the account is on monthly invoicing paid through the manager account, ads stop serving once the account is unlinked, so set up billing under the account or the new manager first.
- Link the new agency while the old one still has access. Send or accept the new agency’s manager account link request, or add its team as users.
- Merchant Center: add the new agency under Access and services, then People and access. Google’s Merchant Center access help says admins can add, remove or edit people, and that removing a person tied to your website verification also removes the verification and your claim. Check that before you remove anyone from the old agency.
- GA4: only Administrators can manage users, according to Google’s GA4 access management help. Keep the Administrator role with your business and give the new agency the role it needs.
- Tag Manager: an account Administrator can change user permissions, and container permissions run from Read to Edit, Approve and Publish, per Google’s Tag Manager permissions help. Give Publish only to whoever will manage tags.
- Remove the old agency last. In Google Ads, open Admin, Access and security, then Managers, and remove its manager account. Then remove its users from Merchant Center, GA4 and Tag Manager. If you run Microsoft Advertising, repeat the same check there.
When should you switch agencies so campaigns do not reset learning?
Switch whenever access is ready, but freeze bid strategies, conversion goals and campaign structure until the new agency has checked tracking. Changing who manages the account does not restart learning on its own. Changing what the bid strategy optimizes for does.
Google’s learning period help lists three triggers: a bid strategy that is new or reactivated, campaigns, ad groups or keywords added to or removed from the bid strategy, and a significant change to the conversion goals or actions it optimizes for. It says learning lasts up to 7 days, and that budget, target and creative changes do not trigger the Learning status.
- Weeks one and two: access, billing and a tracking audit. No new bid strategies, no conversion action swaps, no restructures.
- Once tracking passes: fix what the audit found, one change at a time, with a dated note in the change log.
- New goals: test them in a separate campaign instead of changing the goal on campaigns that already work.
- Seasonal stores: avoid starting a switch in the weeks just before your biggest sales period, so the audit is finished before peak traffic arrives.
What should a PPC agency switch checklist include?
This checklist covers what to confirm, export or move before the old agency’s access ends.
| Item | What to do | Why it matters |
|---|---|---|
| Google Ads Admin | Your company email holds Admin access | Only Admins can add users and unlink managers |
| Manager account links | List every linked manager account and which one has ownership | An owning manager’s admins can change users and links in your account |
| Billing | Move monthly invoicing off the old manager account before unlinking | Ads stop if invoicing paid through that manager is unlinked |
| Conversion actions | Record each action, its source and whether it is primary or secondary | The new agency needs a baseline before changing goals |
| Cross-account tags and audiences | Move conversion tags and remarketing lists into your own account | Manager-level tags and lists stop working after an unlink |
| Offline and CRM imports | Note every upload, connector and schedule, and whose login runs it | Uploads set up under the old agency’s logins need a new owner before access ends |
| Merchant Center | Add the new agency; check who holds website verification | Removing the wrong person removes your verification and claim |
| GA4 | Keep Administrator with your business; add the new agency | Only Administrators can manage users |
| Tag Manager | Keep account Administrator; give Publish only to the tag owner | Tags control every conversion the account bids on |
| History and scripts | Download reports; list scripts, automated rules and feed rules | Change history covers two years; the new agency needs to know what runs automatically |
What should an ecommerce business ask before replacing its PPC agency?
Ask how the new agency will protect what already works. A strong answer starts with a tracking and feed audit, keeps the accounts in your name and leaves profitable campaigns alone in the first weeks. Use the 12-point scorecard above, then add these takeover questions:
- Will you audit conversion tracking before you change any bids or budgets?
- Will we keep ownership of Google Ads, Merchant Center, GA4 and Tag Manager?
- What will you leave untouched in month one, and why?
- How will you handle our Merchant Center feed, feed rules and website verification during the handover?
- Is the contract month to month, and what happens to our data if we leave?
How does Hustle Marketers handle a PPC account takeover?
Hustle Marketers takes over inside the accounts you already own. You keep ownership of your ad accounts, ad spend is paid straight to Google or Microsoft, and our team is added as users. Our fee is $600 to $800 per platform a month for PPC management, month to month with no lock-in.
- Tracking before bids: no bid, budget or structure change until the conversion setup passes our audit, the rule we explain in the onboarding section above. Our Google Ads conversion tracking guide shows what that check covers.
- Live campaigns left alone: if you want a new goal, such as new customers only, we test it in a separate campaign that excludes your existing customer list instead of resetting campaigns that already work.
- Negatives before launch: any new campaign goes live with its negative keyword lists in place, at account level where possible.
- No promised numbers: we do not promise a ROAS, CPA or cost per lead before seeing your data.
- Partner status: Hustle Marketers is a Google Partner and a Microsoft Advertising Partner.

Frequently Asked Questions
How do I find a reliable Google Ads agency?
Shortlist three to five candidates, score them on the 12-point scorecard, and gate on measurement. Verify Google Partner status in Google’s own directory, read Clutch reviews for your business size, and insist on meeting the actual account manager before signing.
How do I evaluate a Google Ads agency I already use?
Run the same scorecard on your incumbent once a year. Then check three numbers: reported ROAS versus backend revenue, the share of spend on search terms reviewed in the last 30 days, and the number of documented tests last quarter. Gaps in any of the three justify a deeper audit.
What criteria matter most when selecting a Google Ads partner?
Measurement discipline, account ownership and relevant proof carry the most weight, at 39% of the total scorecard combined. Everything else is negotiable; those three decide whether the relationship can even be evaluated honestly later.
How do Google Ads agencies compare to in-house managers?
Agencies win below $50,000 in monthly spend on cost and coverage; in-house wins on context and speed at scale. A senior in-house hire costs $90,000+ per year fully loaded, so the crossover point is where that beats a 10% to 12% fee. Many brands run a hybrid.
Should I change my Google Ads agency?
Change when trust in the data breaks, not just when results dip. Results dip for market reasons; data problems are agency problems. If your agency disputes an independent tracking audit instead of fixing it, that is your answer.
What should a Google Ads agency cost?
Expect $600 to $1,500 per month flat at entry level, and 10% to 15% of spend as budgets scale. Compare candidates on 90-day total cost including setup fees, and see our small business pricing guide for tier-by-tier expectations.

What do people on Reddit say about Hustle Marketers?
When a B2B ecommerce store asked r/PPC where to find a Google Ads expert, one reply listed Ishant Sharma from Hustle Marketers among the names that keep coming up in PPC circles, and called out his work on Shopping, Performance Max and Merchant Center cleanup. The same reply gives advice worth following whoever you hire: start with a short paid audit or pilot, and only trust people who can show you real dashboards, reports or references.
On r/hiring, when a business looked for a contract Google Ads specialist to run a 35-location account, another reply recommended Ishant Sharma from Hustle Marketers. The commenter, a web developer, said a client they both work with kept praising him, which they had never seen that client do for anyone. They were also upfront that they could not speak to his results, so read it as a reference on what working with him is like, not as a performance claim.
